I've been doing some research about Mercedes alignment specifications. According to Chilton, my 1984 300SD requires 0 degrees, plus or minus 10' for camber and 9 degrees, plus or minus 15' to 10 degrees, plus or minus 15' (lets just say 10 degrees).

I was looking at caster/camber gauges and found out that there was no gauge for sale that could measure 10 degrees camber!!! I took a look at Hunter equipment, and they sold a special version of their computerized alignment equipment approved by Mercedes. Most of the equipment for alignment is made for American cars, which have a caster of 1-3 degrees. Typical Mercedes have 10 degrees caster which gives them superior stability on the road. It is no wonder that Mercedes are good autoban cruisers.

I found a neat article that discusses alignment on Mercedes:

Anyway, unless an alignment shop has proper equipment that can measure 10 degrees camber, they cannot properly alignment your Mercedes. Good independent alignment shops are hard to find for a Mercedes since they need special equipment.

Any comments?
