Question on Rear Spring Removal
I need to change the spring pads on the wife's 300D and I am a little unclear on how to do this.
I have access to: (1) a Klann spring compressor (2) a grease pit and (3) a two-post lift Would the grease pit be the best for easy removal? Does the car need to be up in the rear, but the wheels resting on the ground or the trailing arms supported somehow? I assume the shock needs to be taken out completely, but the factory manual seems to contradict this. Any help from those who have done this would be appreciated. Rick

the corner to be replaced should be off the ground.
For just pad replacement you do not have to remove the spring, just compress it. On my 126, the shock needs to come off...top bolt behind rear seat. CAREFUL!

An important thing to remember is that the spring compressor works better with the springs slightly compressed as with the weight on wheels. I noticed a lot of scary bowing of the spring if I tried to use the compressor on an extended spring. Ramps are what I used to accomplish this.

I just finished rebuilding the rear of my SD. I had the car up on a jack stand with the wheel removed then used a floor jack to compress the spring slightly. As noted you will have to remove the shock first. All in all pretty straight forward. Just be careful.

Diffy mount.
If you're doing both sides, the safest, and easiest, way to remove the springs is to drop the rear of the rear subframe by unbolting the differential mount where it attaches to the crossmember.
Jack the rear of the car up and support w/jackstands. 1. Remove the rear wheels 2. Remove the rear shocks 3. Remove the rear brake caliper fixing bolts and hang the calipers from something stationary. 4. Remove the rear sway-bar link fixing nuts where the link meets the bar, and separate the link from the bar. 5. Put your floor jack under the differential; put just a tiny bit of pressure on the diffy. 6. Remove the four 13mm hex head bolts which secure the diffy mount to the crossmember. 7. Slowly lower the jack. 8. When the springs fall out, stop lowering the jack. 9. Put it back together the way it was when you started. No spring compressor. No worries. Jay.

Wagon springs.
While you've got the old springs out, chuck 'em in the scrap metal bin, and replace them with a brand-new set of TD springs. The car will handle MUCH better.
