Rear Stablizer bar/subframe mount (?) - PeachParts Mercedes-Benz Forum

How much would bad/worn end links on the rear stablizer bar contribute to body roll and suspension noise?

How much would worn subframe mounts? I don't have any uneven or weird tire wear...

I put new sway bar links on my 300D and there was a *slight* decrease in body roll. I also put in new sway bar bushings up front which helped tighten it up. I've never driven a W116, i wonder how the body roll is compared to a w126?

Well, my car leans like a sailboat when I go around corners.
I do know I have a broken shock bolt and need new links, which I have now.
I guess I'll put 'em on and if the roll doesn't decrease or my banging doesn't go away then I'll look at subframe mounts.

I had "banging" on my 75 450. At first thought it might be the axle.
Turned out to be the rear sway bar bushings on one side.
Wasn't dangerous- didn't particularly sway- just made a loud
banging noise when you turned.

The bushings you wanna replace are at forward points on wishbone rear subframe forward of rear jack points on yer 116, same as 114/115's. And its easy DIY with pair of sizzor jacks. Basically you raise the car one side at a time, then unbolt the old rubber bush and install new. Put the 2nd sizzor jack under rear susp swingarm at the wheel. Takes muscle work and might need propane torch, 3' pipe extension for 1/2" drive brake-bar and possibly sledgehammer. Rear subframe bushings are worth doing, will make a world of difference. It's once in lifetime repair thats easy DIY, costs less than $100 in parts.

My 1980 300SD also yaws and rolls around corners and deffinitely needs new subframe bushings, but I'll install fresh bilsteins first. It's front sway bar bushings that have me worried on mine. They feel shot and dunno how to access them being at 1:00 o'clocl position towards the cabin on 116.

yeah, that ain't going to be fun. I had to remove my brake booster to get at my drivers side bushingmount to re-weld it. It's in there tight.

You done front swaybar bushings on 116?? Understand ye gotta pull a bunch of stuff to git there. It aint something I'm lookin forward to. Please tell me more....

Meanwhile rear wishbone sub-frame bushings aint that bad, done em twice on 114's figure an afternoon. On DIY scale of difficulty I'd rate it 4-6 of 10. Instant gratification includes improved handling, immediate loss or road noise and 'clunk' around corners. Probly ALL 116s and 114/115's deserve a fresh set of rear subframe bushings if the owner's serious about keepin the car on the road.
