Did this video help you?

Amandeep Rakhraj: I always had the understanding that the upper control arm bolts that run through the bushings should always be torqued to spec once the vehicle's suspension is under load (i.e. the position of the arms once the vehicle is on the ground and the suspension is under the load of the weight of the vehicle).

nelias7306: If you put anti-seize on the new bolt that replaces the pinch bolt only on the shaft and not where the nut threads would that help to prevent corrosion next time?

Ieducs Wesps: Excelent Thanks very much

Sam Doms: not permitted to tighten the control arms on the MacPherson strut yet. Ssame reason as the bushings n the bottom side => ride height!

bruce tec: I would not pry on rubber boots. You can use flat chisel in the open to slightly release the pressure on the arms. That way yiu save your boots and do t have to hammer on the arms and marring them. Also your video made me apreciate being a tech I florida. No rust.

madi zaha: motherfreaker that's not a vw toureag

IulianE: this is real world mechanics ,well done!top video!

Dick Carter: One should only finger tighten the bolts through the bushes until the car is back on the ground and at normal level, otherwise, the bushes will be wound-up when static.

tmk111: After few weeks when i did this, one of the arm nearly half way out.... why? i'v putted new bolt.. thanks

VikNucKlHed: Right, PO would have made it easier and maybe would have even saved the bolt

SashaTessa: точно) рассмешил

BobMaplethorppe: This was a huge help! Thanks!

BentleyPublishers: @Gmudan1 when I remove the uppers I install them in the same position they come out at. So the rubber bushings end up in the loaded position when torqued. Otherwise it is nearly impossible to torque the fasteners with the suspension loaded.

VikNucKlHed: Another issue.. You want to compress the suspension prior to tightening the control arms. Saves the bushings (rubber) on the control arms.

BentleyPublishers: @VikNucKlHed That is absolutely right. However when I remove the uppers I install them in the same poisition they come out at. So the rubber bushings end up in the loaded position when torqued. Otherwise it is nearly impossible to torque the fateners with the suspension loaded.

preludin1: Does Bentley include the torque specs?

jacek666b: what torque wrench are you using?

LetMeSeeThis99: What a great video!!! if you make more of these it would help us DIY guys a whole lot!!!. One question: how do you know when the control arm needs to be replace? By mileage, free play by shaking the wheel?

Michal Pátek: Dělal to jak amatér co to nikdy nedělal...postup je poměrně dost špatný..

BentleyPublishers: @Hellz420 Yes, our ebahn DVD does cover that repair.

siucbasser: should have used the penetrating oil first... PO makes life so much easier.

VikNucKlHed: @BentleyPublishers Okay, I will have to buy off on that one... that would require marking prior to removing the bolts. I am just a DIY guy who has been working on my C5 A6 with 181k and ticking on the ODO... keep going on the videos! Good Stuff!!

xplodeedy: Great video !

racespyder: I watched twice to see when you reattached the bolt in the strut to the bottom control arm...video doesn't show that. I assume to put bolt and nut loosely on, then tighten bolts from top, and then torque bottom bolt, prior to installing control arm end to the wheel end?

trucks809: It looks like you can buy just the bushings without the whole arm. How hard is it to remove the bushings from the arm and reinstall new ones?

Ron Greer: great video, very clear instructions! These are also applicable for Passats.

Серж Михалыч: для нас да !

vgorous: im trying to remove the passenger pinch bolt right now. I'm gonna try a hammer drill as a substitute for an air hammer. My driver side came off with some good blunt force, but the passenger side just refuses to budge. I have let it soak with penetrating oil overnight, so I hope when I attempt later tonight, I can get the bolt to break loose a bit. great video. As good as Haynes are, Bentley are the most detailed manuals.

LetMeSeeThis99: Great Job.. but what's the torque pound for all the bolts that you needed to tie down??

Peter Zoch: Hi, what if I got it already dissembled is there a way, template or some easy procedure, how to install them into the same place?

BentleyPublishers: @LetMeSeeThis99 Tightening torques are in the video. They pop up when the fasteners are torqued. Control arm ball joints and bushing fail. Usually causing noise of vibration. Go to bentleypublishers website and get the A6 repair manual for your vehicle. It will answer a lot of your questions.

1970rafboy: Fantastic video

Pendemic: freaking stupid pinch bolts...and idiot mechanics that don't put anti-seize on them.

Hellz420: @BentleyPublishers does the bentley manual dvd have videos on how to change the timing chain on a 2001 gti vr6?

Johan Nyström: Verry good video but i allways put a bit of grease on the bolt thath holds the controll arms so u dont have the problem getting the loose whene u change theme in the future!

GixxerEdis: now how similar is the setup to 09 audi a4?

Vikingdescendent: Well done! Thx.

fawzi147: if the pinch bolt is seized and the penetrating oil , hammer or anything doesn't work . There is only one solution left. If you know how to use a Torch then safely heat the bolt and the knuckle , this will loosen the RUST. But then it will damage the both upper control arms. You would have to replace both of them .

Arun Rao: Excellent instructions. You appear to have followed the factory manual instructions, which is fine, but do you know if it's possible to remove the control arms without removing the strut assembly? I saw at least one other video that seems to indicate that it is possible.

gursharan mudan: great job..just one question when tightening bolts on the bushings , is it not possible to measure the ride or load height before lifting the car , then lift one side up at a time , to attain the height from centre bolt to lip of fender , and then tighten up bolts to toque at right height and torque.

BentleyPublishers: @patrickwbaker You will want to torque with suspension loaded. This video is an overview only and not a substitute for our repair manual.

Rick Born: Great video, very helpful. One issue I ran into (other than that bear of a pinch bolt) was my uppers were completely wore out so I could not reinstall new ones in same position (the old ones just free spun). I had to install arms loosely, then put vehicle at curb weight and do my best to torque upper bolts. You are correct in previous post that this is very difficult to do. I also read that you can measure the angle but my car has lowering springs so the measurements were wrong.

vgorous: It wouldnt come off...I also read in other places that the B6 knuckles were alluminum, not the B5s. Anyway it was in there good. I drove the car to a mechanic to do just the one side of the car. THanks!

Irmantas Stanislovaitis: noises in suspension while drive,shake wheel,pick up car and try move arms with small crawbar but carefull dont damage any rubber parts/cover

Sam Mourad: This video is EXCELLENT, THANK YOU!!!! I'm not a mechanic whatsoever with limited access to tools. It took me more than 5 hours of tapping on the pinch bolt with a 25cm long 5mm diameter punch and a 3 lbs hammer, with half a bottle of PB Blaster to remove the pinch bolt!!! There should be a somewhat easier way to dealt with that bs!!! Comments: I wouldn't remove the upper suspension rack. It is easy to detach the control arms from the suspension easily using 2x19 mm wrenches.

audiocable: blow torch to heat it up, be careful their aluminum

BentleyPublishers: @xplodeedy Thanks for the feedback!

Golden907: How much pounds of torque are you putting on the nuts and bolts?
