Rear Suspension Camber

[brucemillar]

C55 AMG Estate.

So I had the suspension geometry checked out today by WIM. The N/S rear wheel is sitting in at the top (camber). There is no adjustment for this on my car. It is within tolerance so is not causing any real issue.

However... I can see it is sitting in every time I look at the car and so can others.

WIM have done all they can to try and correct this, without replacing control arms and sub-frame etc.

You cannot see if anything is bent and computer says within tolerance. I have no desire to throw parts and money at it. Thinking now is:

1) Ignore it. This does not work as it annoys the hell out of me and I know it is not correct.

2) Fit adjustable control arm to N/S and wind the camber out.

3) Get a Camber Bolt (sometimes referred to as "crash bolts" - Best option due to cost and ease of fitment.

Does anybody out there know if you can get Camber Bolts for the C55 Top Rear? or have any clues apart from rebuilding the entire suspension what I can do?

How old are the springs?

 

[brucemillar]

Don't know how old. But the shocks look new and the springs are black and shiny with three yellow paints marks on each spring. So they do not look old. The car sits level (according to inch tape)

As far as I am aware the eccentric camber bolts/bushes are only used on the lower spring arm inner mount= taking the bottom of the wheel IN as opposed to the adjustable upper camber arms which push the top of the wheel OUT . I am unaware of any adjustable upper arm bush commercially available. Sure you have wheels with exactly the same offset on both sides? This might arise if the front and rears had slightly different offsets[ same width] and had been swopped around at some time? I EXPECT ANY WHEEL ALIGNMENT WOULD HAVE PICKED THAT UP THO.

Is the tyre wearing oddly ? How many miles on the tyres.

What caused you to have the car checked at this point in time ?

There are both types of adjustable devices available - top in/out and bottom in/out.

From Australia and States.

The car was checked after a well documented drive shaft CV boot issue. This showed that the car had most likely had some "light" accident damage in it's history. While checking that out it was noticed that the wheel was not correct. So best way to proceed was to get the geometry checked.

Now there is a distinct possibility that the O/S side wheel is sitting out to far (but it looks OK). The geometry is within tolerance! hence no bad tyre wear.

Has it been lowered at all?

Has it been lowered at all?

I don't know if it has been lowered. Is there any way I could tell? What do the paint marks mean on the springs?

Thanks for the help.

Bent rear frame perhaps?
