[T3] Vibration

[Dave Hall]

Wheel bearings adjusted OK?  Any slack in the suspension?  Steering damper
rubber bush still good - not elliptical hole?  No brake rubbing (rusty area
where the pads were sitting?).   Anything that might allow a bit of
vibration can be noticeable as resonance at a particular speed or wheel rpm.
It may be the damper has failed.  You should be able to check it by removing
one end and seeing if there's resistance to pushing and pulling the other.

You could try swapping front and rear wheels - maybe one wasn't balanced
quite right, or has somehow lost a balance weight.

*We took my '69 Squareback, MT, FI for a 65 mile, "test run" after being
stored on jack stands, in an unheated airplane hanger since October 2010.

After putting the tires back on the ground, everything seemed to operate OK
at city driving speeds ..... but at 55 mph, flat road, 4th gear, there
seemed to be a steering wheel vibration.  50 mph .... OK.  60 mph .... OK.
55 mph, not so good.  Not violent ...  just a bothersome "jitter".

It doesn't seem to be the tires.  They are new radials and balanced.  On a
known, excellent, smooth, blacktop road for 30 miles or so, my other car is
vibration-free.  Not the VW.  UGH!

I can't seem to determine if it's engine rpm's, steering  damper, or what
else it could be.  I'm puzzled.  Could it be wheel alignment?  Camber?
Caster?  Toe-in?

Any ideas?
