88 w126 suspension - jandamerc - 12-14-2014 Hey. I picked up 88 300sel with only 94k miles. Runs great but its got something going on with the suspension. The whole car squats on the driver side. Sits about 1 inch low on the rear and 1/2 inch low on the front. I was thinking springs but idk. I'm wanting to lower this car about 2 inches and I've got some r129 wheels 225/55/16 front and 245/50/16 rear. But I wanted to see about this issue before I tried lowering the car. Anyone got any info. RE: 88 w126 suspension - mmetzdavid - 08-27-2015 Most probably it should be a ball joint, or a bushing. But that's just a guess. When does the car this? In corners, at a certain RPM, when the suspension works vertically, coming out of corners, ...? Another tip is to dig up the sevice history or the paperwork of the car, to see what did they change and when. Or try to move every bit in every direction on both sides, (including the wheels aswell) and try to find the source of the noise/problem. RE: 88 w126 suspension - jandamerc - 09-10-2015 haha. Don't think you've grasped what I'm saying. It's squatting. As in all the time. No noise. I'm going to swap the differential mount and subframe bushings and hopefully that'll fix the rear. Maybe ill get lucky and it'll balance out the front too. Who knows. RE: 88 w126 suspension - Petar - 09-11-2015 The rear suspension is really simple, semi trailing arms, only thing that can fail there are the 2 bushings per arm and the subframe mounts, all cheap and not too difficult to replace. Or it could be the springs. RE: 88 w126 suspension - Hario' - 09-14-2015 If it has some kind of self-levelling badger that might have died. that would cause it. RE: 88 w126 suspension - TurboTim - 09-26-2015 Do you not think it could be a broken coil spring? RE: 88 w126 suspension - jandamerc - 09-28-2015 Nah. They're not broken. Everything looks good. I know the differential mount is bad. So that may have something to do with the rear sagging. I assume the sub frame bushings are bad as well. Gunna change them one day and see what happens. RE: 88 w126 suspension - TurboTim - 09-28-2015 The springs support the car so I couldnt see anything else causing it to sag. The diff could be removed and the car would sit the same. RE: 88 w126 suspension - swampmonkey - 09-29-2015 not al w126 rearends are simple, you could have a antisquat-antidive equiped, but that you would notice as soon as you went under. the bearings gets crap of that, but would not affect ridehight that much. and no Turbotim, the whole rearend is somewhat hold up by the differential acctualy if you drop the differential, the whole rear of the car sags, like a peeing dog,  althou a bad differential mount would not affect one side only imo.  its just to go under and check for worn things, it should not be rocketscience. perhaps you are missing the rubber inlays on that side for some reason? (on top of the springs) or they cut the coils on one side, but didnt get to the other.  RE: 88 w126 suspension - TurboTim - 09-29-2015 I just broke my rear diff. I have it out of the car. I pushed the car around the shop. I can assure you that it will make no difference. Look in the engine section and I have pictures. Are you maybe talking subframe? RE: 88 w126 suspension - TurboTim - 09-29-2015 I gotta be honest the fact that you think the diff is attached to the rear suspension makes me think you have never actually work on one of these cars. Its attached to the subframe but not the actual suspension. RE: 88 w126 suspension - swampmonkey - 09-29-2015 Sorry, my bad, i was thinking of the gen1, the same differentialmount on gen1 holds up the gen2 subframe, ive mostly worked on w115, w116, w123 and w126gen1, the taxfree ones the difference that the gen1 hangs on the diff, and the gen2 hangs beside the diff. -- i was tired, the gen2 w126 is some "wierd adaptation" of 1968-1985 subframe/suspension, missed that swap the subframe mount (if it is bad, should not make a large difference in height thou, and on both side) since you have a gen2 w126 (gen1 differential mount) if it is bad, it holds up the subframe, and thus, the suspension, (A1233511142)
