so i did a 1/8" x2" washer between bushing and frame, as well as SS plate on top of frame followed by 2" washer , 1.5" washer, locking washer and then double nutted with lock tite. is the geometry of the suspension going to be off on due to the 18" washer on the RR ?
Going to do the other side eventually, unfortunately i have a different problem i need to address first, with a low speed wobble in the steering wheel, and vibration at highway speeds,vibration is visible in the passenger seat/entire car .
Just replaced tires, and road force balanced, new rotors pads, new trans and engine mounts, all front suspension components have around 35k on them, and seem solid. idk if this rear failure had any thing to do with it , or if i have a bent spindle up front?

I have a question for everyone that did this repair. Have a C32 with a freaking ripped mount on the passenger side. Is there a way to drill an access hole through the side of the mount instead of the front which means i have to drill in the plastic spare tire well too (which i'm trying to avoid)? Thanks in advance for the replies and really helpful threads everyone!

Wow thanks for the quick reply. I saw that blog post too but was wondering if it was different for the w203 chassis. Also saw someone on Youtube which solved the same issue by cutting a hole in the spare tire well and drilling on the "rear" side of the mount. I've attached a pic of what i mean. Really hope i don't have to resort to this.

Sorry after looking back at the walk through it does kind of make it appear that the hole cut is rearward facing, if you haven't looked at the E55 bushings in person I can see how it appears that way. But I don't think there is any way possible to get to it from the front or back. That trunk deal might work. Joe has a C55 I think? He may have some helpful info for you if the models are similar enough.
