Excessive rear wheel steering
 

I am experiencing some excessive rear wheel power steering with my 92 400E, especially when it rains, I almost have to drive very conservatively during turns, I feel rear wheels want to slide out if I want to keep other's pace in the turn, it is no longer stable at highway speed, car also leans in turns.

Tires are Bridgestone RE950, they are almost new, I have 230k kms on my car, the shocks are original, I did the bouncing test, it seemed OK, the ride heights are OK too. The only noticeable problem I have is the passenger side rear tire is showing some camber, it has more wear on the inner side.

I visually check the multi-links, particularly the thrust arms and torque struts, I couldn't find any collapsed bushings, I shaked the tires back and forth, there was no movement.

I am going to replace shocks, but is the test above enough to show all suspension links are fine? it there any other reliable ways to test suspension links?

If it were my car with that mileage (142,915 miles) , I would replace:

- shocks
- the front and rear sway bar bushings

Check the rear suspension links.
