85k miles on a 2015 C220d

[RicketyRick]

When I drive over bumps, my 2015 C220D Amg Line, which has 85k miles on the clock, slides and kicks to one side. Wheels are in good condition; we replaced the springs. Even the alignment is acceptable. Would shock absorbers be the culprits?

When I drive over bumps, my left rear tire slides to the left and my right rear tire skips to the right. The left is inferior to the right. This problem has persisted for some time; installing new springs and tires helped, but obstacles continue to cause instability in the back.

Just what is it?

The dampers may not be working properly. I am curious as to why the springs were replaced.


By the way, could you tell me what kind of tires were put on, and I'll assume the pressures are right?

[RicketyRick]

The driver side front and rear springs were replaced due to corrosion and damage. The tyre pressures are accurate, and I repaired it for emergency purposes.

Apologies, but those were regular Goodyear tires, not runflats.

Poor damping is what it sounds like. You can rule it out because your tires are of great quality.

Forget it; it's still sliding leftward on bumps. The only part that's sliding is the back left. Ideal is on the right.
I have replaced the rear tires, shocks, and springs but still don't know what the problem is. Maybe bushings are what it is.

I suppose so. Did the last MOT take wear into account?
