Re: [FWDLK] Bad vibrations

[Al Toews <ahtoews@xxxxxxx>]

Can worn components in the tranny tail shaft cause vibration. I'm trying to
solve a similar problem and like John, I've ruled out so many potential
causes. An extra clue I got was when I swapped the rear end gears from 2.76
to 3.55's the rumble moved down the speed scale from 65 down to 50 mph. That
ruled out wheels, tires, axle bearings, alignment and leaves something
between the tranny output shaft and the rear U joint. I've had the drive
shaft balanced twice with no noticeable improvement.  The U joints look fine
and are centered which leaves me wondering about the Torqueflyte . . .

Cheers!
AL

Thanks again for all your replies. On the drive shaft issue - before trip I
did change drive shafts because my original one had a  torn front boot and
it was easier to just change drive shafts than to try and maneuver that boot
off of one shaft and put it on another. I guess one of the things to do is
get a new boot and put the old drive shaft back on. In the meantime though I
do have another car I can take the drive shaft off of and try that one. If I
have no vibrations or vibrations at different speed then it would point to
drive shaft. Whats kind of puzzling though is that vibrations are felt most
strongly in steering wheel, not seat, and that car drove perfectly for the
first 500 miles of trip.
