Rear end of car sagging.. help..

I have noticed that in the past year or so the rear end of my car is slowly starting to sag.. I was wondering if any of you guys know whether if it is caused by the shocks or springs? The car is a 1999 s320. I have also noticed that with the rear sagging so much that it has cause the front to rise. Would that be the cause of my front tires having its outer tread wear more than the rest of the front tires?

How many miles on the car?

Shocks, unless self leveling, will not affect ride height.

You may have alignment issues up front, camber or toe problem.

For the most part you may just have tired springs in the rear, a sagging rear will only make it seem like the front has risen, granted your car is not a see-saw at the local park. My neighbor has an S420 96MY, he has a serious case of worn rear springs, top of tire cannot be seen it is slightly tucked up into the wheel well, he does not have self leveling, he does however have 240k miles or so.

Over 184K and it's sweet!



It MUST have been that leather wrapped dash that got 'er going, what else do you have to offer?

The car has about 113,000 miles on it. I'll try to take some pictures of it and post it.

*if your car has self level*
I had the same problem at 250,000 km. It turns out my accumulators were leaking and I was slightly low on fluid. I had both replaced for $600 including labour. My mechanic also told me there is an adjustment for self leveling where you can dial-in the ride hight. Maybe another member will have more info on this.
I doubt by the age of you car that the springs are tired, so this may be a good place to start.

Yes the lever off the swaybar to the valve can be adjusted, a 10mm nut can be loosened and the linkage can slide to attain a desired height.

My car doesn't have the self leveling shocks. I'm going to replace the rear shocks this weekend and see what results I'll get from it. I figured its about time to replace the rear shocks anyways. I'll have to do it sooner or later. If it rise the rear end of the car back up then my problem is fixed. If it doesn't then I'll proceed to get a set of lowering springs and swap out all the springs. Any suggestion of what brand I should get?? I'm leaning more of Eibach or B&G as of right now if I have to get new springs.

the fron is not raised, replace your rear springs, then do an alignment, and you ll be all set.

I swapped out my rear shocks yesterday and you guys were right... the rear shocks has nothing to do with the height of the car... in the following month or so I'm going to try and change the springs depending how busy my schedule looks.. thanks for all your inputs.. by the way.. after swapping out the old shocks with the new one, the ride is a lot more firmer..

make sure you get the OEM spring compressor when you do the job.

no after market compressor will be able to fully collapse your springs...
