Mercedes-Benz W204 C-Class Rear Spring Replacement

Springs are usually a long life part on a car but if you live in a four season climate, carry a lot of weight in the car or drive a lot of rutted and bumpy roads they can wear out. Springs must also be inspected for rust. The spring carries most of its tension in the outer section and any signs of rust or crack on the spring should have you replacing them right away.

Remember to always replace your springs in pairs.

Changing the springs on a W204 is easy, if you have the right compressor; first safely raise and support the rear of the car and remove the rear wheels; please see our article on this procedure for additional assistance.

I had always planned on doing this via removing the inboard control arm bolt & lowering/raising the control arm with a floor jack, but this method certainly is faster. Also, added benefit of not removing unnecessary hardware with 1 time use self-locking nuts.

However, I still trust my floor jack holding the control arm in place FAR more than I trust those discs on the spring compressor from not shifting & sliding off. Ugh.
