There have been some recent postings about vibration problems at 65mph or
thereabouts. I've been fighting this problem since I purchased my 6 about a
year
ago. To date I have replaced the tires, rebuilt the front
suspension-including new shocks, replaced the rotors, installed a tube shock
kit on the rear,
replaced the half shaft u-joints as well as one of the half shafts that had
some
play in the splines. I have balanced and rebalanced the tires-even checked the
balance with the trim rings on as suggested by Dick Taylor. I took her out
today for a 300 mile road trip. Still shakes. There is no slop in the front
wheel bearings. Oh I almost forgot-front and rear springs were replaced and
urethane bushings were used in the suspension rebuild. There was a little play
in the left trunnion. I didn't replace it-could that be a problem? There is
some lateral runout on two of the stock wheels. They balance out fine on my
spin balancer but is a TR critical about the wheels being near perfect?
My experience tells me that a high speed vibration has to be caused by a
rotating mass. Anybody out there got any ideas?
Thanks in advance Mike C '71 TR6
