Car swinging from the rear when going over slight bump

Jonnykhan · Jan 27, 2014

Hi all

Another issue with my (issueless!) s class.

Basically what happens is when i go over any sort of hump at normal speed the car seems to swing like it is loosing control from the rear end.

at first i thought this was due to the size of my alloys (19inch) so i replaced them with standard 17inch alloys, however this has not stopped the issue.

Just last week, i had the car MOTd and asked him to list absolutely everything that needs changing or looks on its way out. I got everything changed, from ball joints to track rod ends.

Unsure if there is any part that i am missing which is causing this issue.

can anyone advise

thanks

Check you rear sway bar links.

And the associated sway bar bushings.

These cars also have an unusually amount of rubber bushings in other rear wheel linkages that can rot out with age / use.

How many miles on the car?

Was the suspension work confined to the front, or was the back end worked on?

Yes I got the rear bushes changed aswell. However as you said there may be some that I dont know off. Looks like I may need to get this on a ramp and inspect it

I have exactly same issue, were you able to fix it and how???

You'll need to get the car on a lift. Not just the rear suspension bushings, check the bushings on the rear sub frame. I've had to remove the rear sub frame before and replace bushings as well as other rear control arms.
