I am overhauling the suspension on my W140, including control arm bushings.
I have got one front control arm out without problems, but on the other the front excentric bolt is stuck. The nut and the excentric washer came off fine, but the bolt itsself won't move.
I have heated it, hammered it and everything else, I could think of, but still stuck.
Any brilliant ideas?
Can you put a steel bar against the bolt's threaded end? If so perhaps a couple of large "C" clamps can be used to pull against the steel bar and so push the bolt out from it's "nut" side.
This is only a suggestion, not something that I've done so please keep that in mind as you read it.

I don't know the W140 but often, when working underneath older MBs, a right-angle grinder comes in handy...

Thanks for your hints.
Finally got the d... thing out.
It was completely rusted inside the bushing - nothing to see on the outside.
Grinder was also my first thought, but no space to get near the bolt head. Drilled away the bolt at the bolthead end, combined grind and drilled away the bolt at the nut end. The bolt is hardened, so i was a quite job to do. Rubber bushing was not easy to get out either because of the bolt stuck in there. Had to drill out the rubber to take out the inner part and used a hacksaw to carefully cut the outer ring of the bushing to get it out. A total og 8-10 hours and a lot of patience.
The biggest problem I faced was to get the rear suspension control arm bushing into the control arm. I didn't have the right tool but made one from all the other tools. I used an ordinary 12 mm bolt to pull in the bushing, but it didn't withstand the stress. I never managed to get it fully into the right position (both sides of the vehicle) but enough for it to be mounted. I have to do the job over later.
What is the right way to do it?
