I don't know much about M-211's but I had a similar problem with my 78
Datsun pickup truck. The front end didn't seem to have a problem until I
hit 63 mph or hit a bump on the road. It would shake so violently that I
had to slow down to about 30 mph or lose control of the car. It turned out
to be a set of tires that were out of round (about 1/8"). I couldn't
afford to replace them as they were nearly new and the dealer would not
make good on them so I was left with two options. I could have them trued
(which would cut 1/8" of wear off of them!), or I could have a steering
damper installed (which I did) and it solved the problem. You can get one
at any off road store for less than $100. I hope this is of some help.
