You should remember those bolts are ECcentric. The mnemonic is that
they are like most of us on this list.

Dieselvolk,
Yesterday I started the job of replacing the bushings in the front lower
control arms on my '87 wagon, aka The White Whale. It has developed a
steady pull to the right as I've been driving it over the last couple
months. I took it to a local garage to see about an alignment, but the
technician took one look at those bushings and declined. He was very
concerned that the bushings were too far gone and would not even allow the
concentric bolts to turn properly.
Well, I should have pushed him to at least try to align the car. I sprayed
some PB Blaster on all the nuts / bolts that needed to come loose, and then
proceeded to try some of the nicer looking examples on the right side. I
found that both inner bushings concentric adjustment bolts were loose. The
bolt for the rear bushing was REALLY loose and could easily move all over
the place. Clearly the last alignment tech had not properly torqued them,
and so they came loose and subsequently the front end went out of alignment.
They did look awful (the outer visible edge that is), and I'd already
purchased new bushings from the MB Classic Center ($137 per side for the
kit which included new bushings and the replacement one-time-use nuts), so
I decided to proceed. After another few hours and using Rich's spring
compressor and a sawz-all clone from Harbor Freight, I had both bushings
out. Internally, they looked (and probably worked) fine. The rubber had
plenty of life to it, and there was no corrosion at all inside the sleeves
of the lower control arm.
I'm going to wire-wheel the rust off the outside of the control arm, get
some black rustoleum paint on it, and put her all back together. Probably
finish up right side next weekend, unless I get some time after work this
coming week.
