I'm getting ready to replace the rear coil springs on my 2016 E250 4Matic due to the apparently common failure at bottom coil. I've purchased OEM springs and lower seats from EEuroparts.com.
From what I can see, there are two methods for their replacement, 1) use internal telescoping spring compressor to compress the old spring and install the new spring without touching anything else (except the bottom cover), and 2) loosen the spring arm-carrier bolt, support spring arm with jack, remove the drop link, shock, and spring arm-subframe bolts. Slowly lower the spring arm and spring drops out. Finish with reverse. I have two questions.

1. Has anyone used the spring compressor method successfully? If so, which spring compressor do you recommend? Is it really that simple?
2. If I use method 2, what are the final torque settings for the 4 bolts that are loosened/removed?

I would appreciate any recommendations for the best method to use and any information that I should be aware of before I do this.

The dealer wants ~$1300 for parts/labor. I paid $300 for parts.

Thank you!

I do not have MB type spring compressor.
But I done rear springs removal.

To note : Whenever you remove the big arm for the spring at its bushing at subframe side, you must re-install it at ride height ( pre-tension ).

Example : Normal droop as is




RIDE HEIGHT adjusted



Becareful, that is +-500kg of force to make spring be at normal ride height.



Torque. Spring arm bolts at wheel side.

I use this type of spring compressor, not the best for MB rear spring but not too bad.


I can only use 1 compressor and not 2. It is more for my own protection , this spring compressor .
Single unit can not press down properly a spring if this type of design.

Good luck

I replaced the rear springs on my 2013 GLK350 by compressing the springs. I have a lift and a transmission jack and an impact driver to thread the spring compressors. As other posts mention, please be very careful, this is a dangerous job. It is not difficult but please move carefully and make sure the spring compressor is in place properly.

Thank you very much for the detailed response! It sure has given me a lot to think about.
