My friend Don actually bought the kit. It had 4 pieces; he used two on his 1974 240D and put the other two on my car. When I see him I will ask brand or part number and where he got them...

No, the rear axle is completely different in W114/W115 than in W108.
That was used in W110, W111 and W108:


..and the strut or the spring is located behind the rear-axle.

But W115/W114 had similar construction as W123 and W126:

They are called Spring Helpers and he got them at O'Reilly Auto parts. The spring helper does not go on the Compensator. The Spring Helpers go on the suspension springs. The pictures above do not show the suspension springs.

I will crawl under my car and take a photograph.

Can you put them on without a coil spring compressor? I'm considering this as an alternative to swapping my springs.

Yes, no compressor needed. Actually you would do the opposite of compressing; you would jack up the car which and install the helper between coils.

Would not place anything between the springs. Doubt that your springs have been compromised. If the top of your rear tires cave in then you have a camber problem that is most likely related to the hydropneumatic compensator. Check the HP compensator first. If it is shot then switch to the coil spring kit and you should be fine.

Cool, I'm eager to see if I can find these for the rear springs on Wilma. They're tired, and I think the little rubber pads have rotted away. She's never going to be a track car, and this seems like the simplest solution. Has the ride quality changed dramatically on your 108? I need to bring my ride height up, did it bring yours up?

The earlyer car's had a spring you need the spring and bracket. and you can do away with hyd.

Spring Helpers totally worked for my W114, check my (ongoing) thread on old Wilma for details about them. Thanks for the assist Jeff.

I had that problem with the kit; the car sat way too high, and in fact higher on one side than the other. The spring included with the Febi kit has the same part number as the spring EPC lists as being for vehicles where "on special request, harder spring suspension" is installed. It is visibly heavier/thicker than the weaker spring (110 329 04 01) which I obtained from the MB dealer. The weaker spring corrected my ride height problem.

Having seen in this thread that the rebuilt compensators are available, I may go ahead with that. I was reluctant to buy a NOS unit because the nitrogen charge and rubber components in these only lasts so long before seeping out. So even a new unit that has never been on a car before may not be in top shape. Still, 700 Euro is a lot...

Now, I wonder who might still have one of the NOS never previous installed compensators still on the shelf.......Rubber boot has been compromised, though.

Look under the rear trunk at the 'V' shaped mount at the differential. If the middle part in this has come loose from the outside frame and dropped to the bottom of the 'V' shaped frame, then that's the problem. That 3/4 inch drop in the middle has a much larger effect in height drop in the body.

My 72 280 se 4.5 was sitting to low on the back. My compensator was gone so I bought the spring kit and then it went the opposite. Now is sitting too high with one side higher to the other. I hate that look!

I'm a little late to the party but I'm trying to catch up.

My 1968 280 S parts car had a very hard rear suspension. I've moved the engine/trans into my 1967 250 S car, which was always the plan. The 250 S sags like crazy. Really sags.

So from what I'm reading, it's either wimpy springs or a worn out hydraulic spring compensating gizmo, is that correct? I'm wondering if someone put bigger springs in the 280 S and that's why it doesn't have the problem. So anyway, what do I need to do? see if one of the cars has this hydraulic thing and switch them between the cars? Or replace it with a "spring kit"? The link to spring kit did not work for me.

Help?
thanks
Scott

If your butt is sagging, but the wheel camber is normal (itself a debatable amount), then it is the road springs; if the rear end is sagging and the camber is quite negative. Then the compensator comes in to play and is likely defective.

Or so I hear...

Cheers.

Pat
