    Time to do Control Arms. Best options..

    Guest-only advertisement. Register or Log In now!
    3 of my 4 upper control arm bushings are worn or torn (75K on the clock), so I have some work to do. I searched through the forums, and found a lot of people are running the AWE SPC kits, how are they holding up after 10K or 20K miles?

    I was originally looking at getting an aftermarket control arm kit, but a local Audi/VW shop owner claims the aftermarket SPC type "pop" and "click" after even just a few thousand miles. He also claims he sees cars with these problems frequently, and commonly returns them to stock for customers due to these issues. I actually didn't ask which kit specifically he was referring (although he did mention SPC bushings), but I know they sell parts from many aftermarket Audi vendors.

    I think the kit I want is actually the 034 adjustable kit, as they are rebuildable and I have always had excellent luck with 034:
    https://store.034motorsport.com/034m...s5-q5-sq5.html

    I am also looking at the AWE kit, but I have no experience with AWE....:
    http://www.awe-tuning.com/make/audi/...ontrol-arm-kit

    And of course, there is always the option of staying stock.

    Right now my suspension is stock, however I am planning on going either full K&W V3 coilover or perhaps just a simple Eibach spring switch soon. I am still debating the best option there as well, I had K&W V3 coilovers on my last car (S4), and loved them. But honestly, once they were set up, I never adjusted them. So I just don't know if they are worth the money, since the best thing out of coilovers is adjustability. I'm wondering for my daily driver city street mule if I would be better off with some Bilstein shocks and Eibach springs. But in either case, if the car is going to be lowered a little bit, that does make an argument for getting adjustable control arms.


    So, I have to do this repair regardless, and any input from owners who have experience with control arm replacement would be greatly appreciated. Esp 034 or AWE aftermarket kits...with decent mileage....

    I have the SPC Arms and H&R Coils on my A5. I get that clicking/popping noise when going into my driveway, but not during normal driving. I drive my car a lot so I have had to replace the bushings twice (75k and 130k) and other than the previously mentioned driveway noise, the SPC arms/bushings are the same as the oem ones. Noticed you're in Utah, PM me if you'd like to meet up and we can take the car out so you can experience it first hand.

    Hope this helps!

    Greetings fellow enthusiasts :)
    When my 08 3.2 A5 went for service last month, I was also told that the upper control arm bushings were worn.
    The dealership quoted ~$850 for the job - I'll prolly not go with them for the job.

    In a lot of threads I read on the forum, the control arms were also replaced when the bushings were worn.
    Is that the norm? Or can just the bushings be replaced?

    Technically the bushings can be replaced, but the balljoints in the control arms wear out as well. You may as well swap out the entire arm.

    034 makes a density line non adjustable set for $180. They also make an adjustable set for I believe around $400. A TRW (OEM) set is about $200, SPC and LYKT both make adjustable sets.

    $850 is a lot. I just did mine this weekend (TRW, would have gone with 034 but they ~just~ released them) in my driveway in 2 hours. You will need an alignment afterwards.

    What is a sign your bushings are torn by driving or just really worn, without obviously jacking the car up and looking? I am at 85K with everything stock aside from H&R OE springs. I plan to either replace the stock shocks with Bilstein sport shocks this spring, or perhaps go to coil overs. Car rides pretty damn good still with everything being not refreshed to my knowledge.

    Definitely looking for input on this as well, my '09 A5 is at 115k miles and my mechanic informed me that all control arms on the front were worn and needed to be replaced.

    I was thinking about going with the 034 upper and lower complete set for $495 since it seemed like such a strong value to me. Anyone have input on the 034 non-adjustable control arms? I'm not really planning on lowering my car or doing a lot of suspension work. Also, is there's a DIY for the upper and lower control arms? I have access to a lift and tools, but on a tight budget so I'd rather not pay labor for it.

    Much obliged.

    My local shop quoted me $650 for he job. Most of the aftermarket solutions are rebuildable, but I think it is best just to replace the entire arm if it is stock.

    Yeah, I was checking that out too....034 just came out with a Density Line variant...might be another option....

    There can be a lot of symptoms, depends on the exact cause of failure (worn/torn, which one, ect.

    My car feels a little squirrelly when hitting certain bumps or driving on a road with even minor ruts; the wheel pulls to a side when it shouldn't. When I hit a bump with say the right front wheel, the car will pull and track to the right a couple inches...this typically won't happen if all the bushings were good. It will also 'walk' a little bit when driving on roads that have ruts in the asphalt. There is a road like this on my way home from work, and lets just say on that road I have to keep my hands on the wheel to keep the car going in a straight line.

    Then recently, it started to act funny when in reverse. If I back straight up, it's fine. But if I back up and turn the wheel all the way to the left, I will get a "pop" from the right front of the car, and to an extent it almost feels like the car is dragging the right front wheel. Same thing but on the left if I back up and turn the other direction.

    But although I knew something up front wasn't right, I didn't know what was wrong until I had looked into it.

    Yeah, I'm really considering that Density Line kit as well. I'm wondering if 034 will mix that with the adjustable uppers, as I would want the ability to adjust when I do wheels/tires/springs (coilovers?). I kinda feel since my uppers are so bad just to have the lowers done while I am in there anyway. There can't be much wear left of the lowers and the balljoints if 3 out of 4 of my uppers are torn....

    Thanks for the inputs
    Forgot to mention my car has ~88k miles and I think it's on the factory setup. So I think it should be a good move to replace the arms as well.

    The dealership's quote was $860 with OEM parts - I suspect it is only going to be bushings! plus $150 for an alignment.

    A reputed indie shop quoted $1150 with the Density Line (full kit I'm guessing) including the alignment. That seems reasonable considering that the kit is ~$500.
    But is that going to be overkill? Or would it just be preventative replacement? Do the lower control arms/bushings wear "as often" as the uppers
    I've been seeing OEM front upper control arm kits go for ~$200 (confirmed by previous posts as well).

    I've wrenched a lil bit on my Porsches and an Mk1 TT that I briefly owned - no means an expert
    Still need to figure out if this can be a DIY with the tools I have. Is there a good DIY post for this anyone is aware of?

    It's a very easy diy. I don't know of any b8 specific, but its very similar to the b6 and b7.

    After jacking up the car and removing the wheels, the tops can be done with two 16mm wrenches, a hammer, and a punch. I don't know what size the lower control arm bolts are.

    So I dropped off my car today to replace all my control arms with the 034 motor sports density kit and install st coilovers and paid $500 for the installation of everything

    If it's this easy then I'll order the density line kit this weekend and do it myself in my garage.

    I really need to get new control arms, does anyone know a good youtube channel or DIY site that has control arm instructionals? I've never done anything this "involved" before, but I am more than willing to experiment so I know for future maintenance. I will start my online search regardless, but it would be great if folks here already had tried and true instructionals that worked well.

    Here are a couple of YouTube videos I came across.

    This one's on an A4, but pretty detailed on the procedure.

    How are you liking your Airlift?
    I'm on bags too, but I somehow feel like I lost traction control.

    Is that normal?

    I love my airlift system. No issue whatsoever. Been on air for 4+ years now.

    Lost traction control? Dont know about that one...

    I almost hydroplaned off the highway yesterday going only 60 miles per hour.

    Front wheel drive Hondas and Toyotas were passing me left and right..

    Called Audi this morning, and they said that most likely, the Air Suspension is not letting the car communicate with the road?

    Not sure if Audi is correct.

    OP I have 034 adjustable kit and does its job!

    Silly question: but how are your tires?

    Hydroplaning would be more as a result of tires than suspension. Not sure how traction control would help in that instance, either.

    I got new tires performance all weather tires 2 months ago.

    Wouldn't traction control help with hydroplanning? I'm not sure.. and the Audi tech didn't have any experience with bagged cars, but his conclusion was that because the car's suspension does not communicate with the ECU, it doesn't know when to activate traction control?

    I have noticed that on my air ride set up in the rain on a very very wet road the car gets a little floaty like it's hydroplaning. If you air up just a tad the problem goes away. I believe the reason is that there is nowhere for all the water go when it's being thrown off the tires causing it to stick in the treads so to say (definitely not the technical description of this). By airing up just a little its allowing the water to escape the wheel well allowing for more traction.

    Again, not the technical explanation I would like to give but those are my results. Also, I have plenty of friends who are static and really low who have experienced this same problem.

    I just switched from the SPC to the 034 upper control arms this weekend. Took about 20-30 minutes to change all 4. The 034 seem to be higher quality and I love that they can be rebuilt. The SPC have a wider range of adjustability.

    For the hydroplaning it could be when you lower your car it could be throwing off your toe. It will cause a car to hydroplane, because it forces the two front wheels to fight against each other, and there is nothing that traction control can do to help you. A lot of people think that negative camber wears out the inside of your tires, and it does a little, but toe being off affects it much more. It does help turn in, but it is brutal for tire wear and driving in the rain.

    Ok, that kinda makes sense! I'll air it up and drive a bit slower next time!

    Thanks for the feedback!
