Audi A6 C6 type 4F upper control arms replacement tutorial. A step by step guide. Be sure to check out the video on proper alignment of the arms before tightening.
Never tighten the upper control arm bolts down until the suspension is at ride height. Use a jack to raise the suspension to about the point where it would be with the wheel on and on the ground. This will also help seat the upper control arms in the spindle. If you don't do this, you will tear the bushings out.
Everyone - you're right pointing out the wrong alignment. must be done in the neutral position. I put some ideas together in an addendum video. thanks for picking that up and pointing it out.
3:00 My friend, when you place that Jack under the car, that spring loaded plate MUST be flat with the ground! That could be a crucial mistake. I bet that spring on the jack it's crushed down towards the plate.
good afternoon to all and on the pneumatic Audi A6 /S6 sedan III 3.2 FSI quattro how to adjust the angles of the upper levers.what is the distance to throw off the pliz diagram Height for the front lever … Height for rear lever …
Would reinstalling the bolts inwards benifit the next mechanic, that way you won't have to take it out completely. What's the science behind it. Sometimes I feel like Audi does shit like this just to make it harder. I did a starter replacement also on this a6 which was an inconvenient bolt Situation too.
There is a major mistake from 19:38 to 20:08. You only tighten these upper bolts when the car suspension is under load and the control arms are in a neutral position. To do that, place a jack under the steering knuckle and take the weight of the car, then tighten the bolts. Otherwise it will cause premature failure of the control arm bushes.
Hi Gladius - thanks for pointing this out and yes indeed it's a mistake. I'm adding a link to this video to correct this. unfortunately you can't edit already uploaded videos. My bushes did end up tearing so please everyone - TAKE NOTE and click the link to the correction!!
Please note 04Interc3ptorP71 - and disclaimer - do this fix at your own risk. I can't guarantee this fix won't cause any damage. Mine worked out well with 60 000 km later no issues.
Hi All - I'm adding a correction to aligning the control arms as per the comment from 04Interc3ptorP71 and Gladius. Click on the link in the video at the end.
i can tell you from biter experience, its not this easy when you live in the UK with salted winter roads, more often than not, that top pinch bolt will shear, I only wanted to replace the upper control arms but ended up buying all suspension links as well as a steering knuckle as that damn bolt would not come out. I watched your video before i started this job and thought - well thats easy enough, i can do this, and 4 weekends later, the car is still off the road - eeeeish!

Agreed. I did actually make that mistake and it did tear the bushings. PLEASE TAKE NOTE! I should actually fix that in the video
Works performed at a nice, patient pace with sensible filming. Think I might give it a go if my A6 fails its MOT test....Many thanks
Welcome Adam - just note the control arm alignment correction. very NB!

Great Job !
Thanks Art - just note the control arm alignment correction. very NB!
Great video, very clear, one of the best I've seen. I couldn't see an axle stand any where, I assume you didn't use one?
no I didn't use one. guess it's safer though.
Quick question - did you only jack up one side of the car?
Excellent video - this makes me more confident for doing it on my own! 👍🙌 Thanks!
yes only lifted one side at a time
Great Video. Do You must take the whole part out to change the arms? Can one of the upper arms be change without removing everything?
Thanks
Yeah but you end up tearing the other arm from moving it too much
Don't think so - it's not that difficult to just remove everything
3:00 My friend, when you place that Jack under the car, that spring loaded plate MUST be flat with the ground! That could be a crucial mistake. I bet that spring on the jack it's crushed down towards the plate.
Agreed hence the addendum I added. ended up tearing the joints in a few thousand km. must be level
So, definitely need to remove the strut?
couldn't see a way around that

Oh - and I cut out the part where I said to keep the suspension down. That's wrong.
I had this change now it squeals when I turn, what might be the cause
sorry I'm not sure why that would be. have you resolved this?

How did u remove bolt clip off?
yes that thing isn't easy. had to pry it off really. but it does damage it. just bent it right again before I put it back on.
