This physical care for outlines the replacement of the front end command arms. They are commonly referred to every bit “control arms” although Audi has specific names for each ane (see below). There are a full of viii arms, 4 on each side comprised of ii “uppers” in addition to ii “lowers”.
The Audi translation below volition assist if you lot are ordering parts from the dealer or demand to search inwards the Bentley manual.
Guide Link = lower curved arm
Track Control Link = lower direct arm
Upper Rear Link = upper round/straight arm
Upper Front Link = upper curved arm
Let's utter strategy. While it is possible to supplant arms individually, it doesn't ever brand feel from a labor standpoint. In theory, or in addition to so of the arms concord upward meliorate than others. Isolating a special arm for replacement though is tricky. Once you lot read through the procedure, you'll sympathise why audipages recommends replacing all viii every bit a “set” in addition to changing the sway bar links in addition to necktie rod ends at the same time. This approach minimizes the amount of labor in addition to volition brand your front-end experience similar new.
Why supplant the arms at all? Telltale symptoms are, squeaking, rattling, groaning over bumps, knocking in addition to alignment issues. If you lot receive got the master arms in addition to are over 70,000 miles, consider replacement if you lot are experiencing whatsoever of the symptoms above.
It is imperative that you lot teach an alignment done later on performing this procedure. The nature of the Quattro organisation disguises what commonly makes a 2 bicycle drive auto experience out of line. In other words, merely because the steering is non pulling to ane side doesn't hateful the alignment isn't out of spec.
Changing all of the arms, swaybar links in addition to necktie rod ends is easily a $2,000 addition task at the dealer. This special physical care for has ane of the highest payback inwards damage of savings. This is a fourth dimension consuming task but non overly complicated.
Before Performing the Job
Before offset this project, it is really of import that you lot spray penetrating petroleum (PB Blaster) onto the pinch bolt shown below, preferably over several days. If this bolt cannot live removed it has to live drilled out which volition add together hours to this procedure.
While you lot are waiting for parts to arrive, maintain soaking it everyday. If you lot excogitation on changing the necktie rod ends, soak those bolts/nuts every bit well.
Spray the areas shown in addition to necktie rod cease threads if planning on changing them.
Prior to ripping everything apart, run into if the bolt tin flame live partially removed every bit shown above. If not, you lot receive got to determine whether you lot desire to forge ahead amongst this project. There is no agency to take away the upper arms amongst the bolt inwards place, in addition to so you lot receive got to figure out a agency to take away it or accept it somewhere to receive got it done.
This is a showstopper if you lot can't teach past times this point…..
Time: 7-8 hours if foremost fourth dimension in addition to bolt is non frozen Parts: Control arm “kit” which usually contains 8 arms, sway bar links, necktie rod ends, hardware. I receive got had proficient luck getting the Meyle kit from blauparts.com which has all of the hardware all the hardware (with exceptions below) for around $500.
Tools in addition to Materials Required
Procedure
This physical care for details replacing all viii command arms, necktie rod ends in addition to sway bar links. Refer to the relevant department if you lot are exclusively doing a partial replacement. I recommend doing ane side at a fourth dimension for ii reasons:
1b) Jack upward ane corner of the car. Leave the jack inwards house in addition to seat a jack stand upward underneath every bit a backup. The auto volition live inwards the seat for many hours in addition to so makes certain that it's absolutely stable. Remove the wheel.
2) Remove the belly pan in addition to laid aside.
3) Remove the (2) 13mm sway bar bolts on each side.
4) Disconnect the sway bar links from the lower, direct command arms on each side (16mm). You should right away live able to take away the sway bar in addition to seat it aside.
WARNING
Have a jack underneath to back upward the entire bicycle housing. Once you lot start removing the arms, the exclusively affair supporting all of the weight becomes the axle in addition to necktie rod assembly, which you lot don't desire to practise !
5) Remove the bolt that connects the bottom of the strut to the direct arm. The strut volition rest connected to the auto from upward above.
6) Remove the nut/bolt that connects the lower direct arm to the frame. Once removed, accept a safe mallet in addition to knock it downwardly in addition to so that it is exclusively connected past times the ball articulation end.
7) Under the hood, take away the plastic embrace in addition to so you lot tin flame access the ii safe plugs the embrace the strut nuts. There are (2) 13mm nuts that demand to live removed amongst a deep socket. Put your mitt on the strut spell removing because that's all that is belongings the strut inwards place.
Optional method: you lot tin flame leave of absence the strut inwards house in addition to take away it along amongst the sub-frame. It makes it a lilliputian heavier in addition to patently a lilliputian bigger to maneuver out but at that spot is room. The payoff to doing it this agency is that the strut nuts are much easier to access when on the ground.
Once the ii nuts are removed, the whole strut assembly tin flame live removed in addition to laid aside. While non covered here, this is a perfect fourth dimension to modify your struts if needed.
8) Remove the balljoint cease of the lower direct arm past times removing the nut on the bottom in addition to role a pickle fork to teach it out. Another method is to loosen the nut in addition to so that it's fifty-fifty amongst the top of the threads in addition to role a hammer to drive it out. This gives you lot a bigger expanse to hitting amongst the hammer.
BOTH methods are destructive in addition to so exclusively role when replacing the arm amongst a novel one.
Status Check: At this point, the swaybar, strut assembly in addition to lower straight-arm should live removed.
Note: I receive got changed the enterprise of this physical care for later on doing it a bunch of times. I mean value it's easier to swap out the upper arms foremost earlier removing the lower curved arm. The exclusively argue is that it helps maintain the strut housing supported a lilliputian more.
9) The ii upper arms are pretty tardily because you lot genuinely take away the whole “sub - frame” which they connect to. Also, the hardware is a lilliputian to a greater extent than protected in addition to thus rust is non an issue.
Upper Sub Frame Nut Locations
Under the hood, at that spot are v 18mm nuts that demand to live removed (see pic below). They are what concord the sub frame to the trunk of the car. Remove the ii dark covers in addition to so you lot tin flame access all of them (you should already receive got at to the lowest degree ane off already to take away the strut bolts). At to the lowest degree ane on the rider side is obstructed past times a hose, in addition to so hunt around a little.
You tin flame run into the relative positions inwards the film below in addition to the Bentley diagram above. The Bentley pic is around looking direct downwardly at the strut tower.
Upper Sub Frame Removed
Depending on the year, you lot powerfulness receive got an add'l brace shown higher upward - it is non “required” to live reinstalled according to the Bentley. If you lot practise non reinstall, seat the bolt in addition to 18mm nut inwards the hole where the brace was located every bit shown above.
10) The direct arm has a circlip, which needs to live removed first. The circlip is seat inwards at the mill to assist during production. It is non required for reinstallation but I seat it dorsum on anyway. Reinsert the special bolt for the direct arm in addition to the clip volition concord it inwards house until you lot teach the sub frame reinstalled.
NOTE: Both arms receive got a metallic spacer amongst a taper on ane side where the bolts move through the sub frame. They powerfulness autumn out when the sub frame and/or arm is removed. No large bargain - the taper faces downward. Just brand certain that they are at that spot when you lot reassemble. If ane or to a greater extent than of the spacers are “missing” await upward into the hole in addition to it powerfulness live stuck inside.
11) The upper curved arm removal in addition to reassembly is pretty straightforward. The exclusively affair you lot demand to live aware of is the seat of the arm inwards the sub frame earlier tightening the nut. This is of import because if the arm is inwards the incorrect seat it volition stress the bushing prematurely. Once it's inwards position, torque to 37 lbs + ј plow BEFORE you lot install the sub frame (you won't receive got access to the nut otherwise).
Dimension “a” should equal 97mm (+/- 2mm) or 3.81”
At this point, the direct arm volition live fairly unloosen inwards the sub frame exclusively beingness held past times the circlip in addition to the curved arm volition live locked inwards position. Time to reinstall the sub frame.
STOP: Make certain the tapered spacers receive got been reinstalled in addition to that the curved arm has been torqued to spec.
12) Reinstall sub frame. Torque 5 nuts to 74 lbs.
13) Connect the upper arms to the bicycle bearing housing past times reinserting the pinch bolt. Use anti-seize inwards illustration you lot demand to practise this again. Tighten to 37 lbs.
14) Reinstall strut assembly, torque 13m nuts to xv lbs. Pop safe grommets over holes in addition to reinstall plastic covers. You're done nether the hood for this side.
15) Reinstall lower straight-arm on the ball articulation cease foremost in addition to mitt tighten the nut. Lift upward the arm into seat in addition to so that you lot tin flame reattach to the frame in addition to also to the strut. This volition accept a lilliputian trial in addition to mistake to teach everything lined upward in addition to so the bolts move through. The tapered alignment tool is a large assist here.
I would re-use the mill nut amongst the large washer. If your kit came amongst a lock nut, it's likewise pocket-sized in addition to volition torque downwardly on the insert within the bicycle bearing which tin flame slide out - Hand tighten for now.
Did you lot lose the orientation of the bolts? That's why you lot practise ane side at a time!
Ok, right away that the uppers arms are swapped out in addition to the lower direct arm is removed in addition to installed, it's fourth dimension to tackle the lower curved arm.
16) The curved arm is a lilliputian tricky because the nut is inaccessible without loosening the sub frame in addition to prying it downwardly to allow clearance for removal. Someone came upward amongst the see of reversing the novel bolt, which eliminates this step.
In enterprise to practise that, you lot receive got to cutting the erstwhile bolt off. There are many ways to practise this - trunk saw, grinder, dremel tool, in addition to sawzall. The bolt is extremely difficult in addition to volition accept a lilliputian fourth dimension to teach all the agency through. Trust me, fifty-fifty if it takes you lot xv minutes a side, cutting the erstwhile bolt is a much meliorate pick all around.
I bought an expensive air trunk saw for this task in addition to it merely doesn't receive got plenty torque for this sort of cutting. Influenza A virus subtype H5N1 cutoff bicycle on a grinder is the quickest but access is a lilliputian harder. Although bulky, a sawzall amongst a proficient metallic blade industrial plant well. Cut roughly 1/3, rotate, in addition to repeat until you're all the agency through.
Tip: You tin flame gain to a greater extent than access past times loosening the fender liner in addition to peeling it dorsum out of the way. Remove 3 10mm plastic bolts (one on the bottom in addition to ii within the bicycle well) in addition to take away in addition to the Philips screw on the side. Pull the liner off of the 3 metallic studs in addition to role a bungee cord to concord it out of the way.
Due to sub frame interference, the curved command arm bolt won't come upward out in addition to it is easiest to cutting amongst a move out grinder in addition to cutting off wheel.
Lower curved command arm bolt cutting for removal.
17) At this point, you lot tin flame reinstall the novel lower arm. Installation is the opposite of removal amongst the exception of inserting the novel bolt inwards the opposite direction. Where you lot saw the nut previously would right away live the bolt head. Working the bolt through the hole inwards the frame is a lilliputian tricky but you'll teach it.
Install the ball articulation cease the opposite of removal. I would re-use the mill nut amongst the large washer - same lawsuit every bit the direct arm.
· Tighten both ends basically mitt tight. All concluding torque settings volition live done on the ground.
18) Reinstall sway bar links to the lower direct arm. Don't connect the sway bar cease merely soundless until you lot consummate the other side. Torque to 52 lbs.
Everything should live dorsum together now. It cannot live stressed plenty that you lot receive got to seat the auto dorsum on the ground, bounce it upward in addition to downwardly a few times in addition to start out torquing all of the unloosen nuts/bolts. It's tiresome but necessary to practise it this agency in addition to so you lot teach the maximum life out of the novel arms. Refer to the torque specs below.
The exclusively affair left to consummate ane side is the necktie rod end. They are pretty straightforward but similar the pinch bolt, seized hardware could live your biggest obstacle.

Some of these are for reference; you lot can't agree a torque wrench on every fastener.
Upper sub frame nuts - 74 lbs (same for vertical brace if applicable to your twelvemonth in addition to you lot create upward one's take heed to reinstall it).
Tie rod - top bolt (7nm or x inch pounds = non tight at all)

- Use an 18mm wrench on the necktie rod cease to lock it inwards house spell using a 22mm wrench to loosen the nut on the threaded shaft. Once it's loose, leave of absence it inwards house for now.
- Remove the 13mm bolt on top of the necktie rod. This ane should come upward out really easily.
- Remove the nut on the horizontal bolt. Tap out the bolt amongst a hammer. These tend to teach frozen likewise in addition to so role anti-seize on the novel one.
- You should live able to disconnect the necktie rod from the housing amongst a twosome of taps downward amongst a hammer.
- Now, either accept a measurement, or count the threads in addition to so you lot tin flame teach the novel cease installed reasonably close.
- With the nut backed off, start unscrewing the cease from the threaded shaft. Keep going, it powerfulness accept quite a few turns.
- Installation is the contrary of removal, refer to torque specs below.
- If the horizontal rod bolt doesn't move through it's because the necktie rod is keyed inwards the incorrect place.
