Hello everyone-
my car - w123 023 , euro 230 sedan...
this has been a debate of mine with my father for some time...my rear subframe mounts. i have read that after these past 23 years they can be very exhausted and in need of replacement for various benifits. i own new ones but my father is very leary of doing the repair in regards to our location...We are in buffalo,ny and the car was used here before i bought it. we had one ruff ride sealing her back up, restoring the chassis,metal,frame,etc...he feels that pulling those bolts might be a can of worms if the threaded area is destroyed, rotted out or in trouble. it would become a large task to take them out and replace with new thread boxes, or in the worst case the car could recieve a fatal blow, these are worst case situations. everything else came apart and was restorable, only one caliber bolt ever broke and needed to be drilled out and re tapped.... has anyone in a salted winter climate (or with a compimised w123) changed these and if so what did you find out?
thank you-
jake
ps the car rides and tracks fine.

Rear subframe bolts, if they are still in from the factory, should be covered in thread lock. You shouldn't have a problem with the rust as long as there is thread lock on the bolts. I would give it a shot personally. I don't think it will be a problem.

You may want to get a second opinion though.

yes they are the oem as far as i know, i bought the car seven years ago and have no record of them being changed, and they look 23 years old.
thank you for the info -jake

I have a old 72 SLC, had all replaced. We were all concerned about that same possible problem. There was none. Car does have some good bit of underbody rust, nothing that can not be fixed. Hope this helps, I would go for it.

YES they came out, nothing broke....everything is moving along a o k on the rear end rebuild.

thanks all, another rusty old MB comes through
