We here's my experience on some vibrations, of course actual test results may
vary (LOL),
I just took the car out for a road test after putting the drive shaft in the
right way, seems my mechanic (uh that'd be me) put it in with the sliding
shaft closest to the diff. Also switched out the old axles which had more wear
than I had thought for some "new" (THAT'S BE NEW TO THIS CAR) axles. Now the
constant vibration which started at 85 mph is no longer present at least up to
100 mph, not sure beyond that point.
The vibration I was getting under slight deceleration and acceleration at
+75 is no longer present. At least I think so as it's a little hard to tell
with the tranny cover removed, because it was a vibration that was slight and
with the tranny cover on it was a little hard to feel and hear.

Subject: Re: vibration on a 72 TR6 very stock
Oliver,
No help here, but I've got a slight vibration on very slight deceleration
but not when fully off the throttle. Also a slight vibration at small
acceleration, not mashing on the gas completely, but just giving it a little.
It's most noticeable at over 75 mph. The Vibration gets worse at a constant 85
mph and over. I had the tranny cover off to look at the drive shaft while in
motion to see if that was it and no vibration there it was rotating smoothly.
So that narrows it down to what's behind the drive shaft, axles, U-joints,
diff. All the u joints are new, but I'll look at the axle shaft ones again. I
did notice both axle shafts have about 1/4" slack in them, either u-joints or
worn splines. I'm leaning to the axle splines, because when I hit a bump in
mid curve the rear end acts up and gets squirrelly.
I am running steel wheels, but don't think this would be the cause of
vibrations at the accelerating and decelerating conditions. If it were due to
the wheels it should be a constant thing. Maybe the steel wheels are causing
the constant vibration at +85mph?
I want to check the axle shafts and their u-joints before putting my new
Dayton wires on the car. As I don't want to change two things at a time, if I
do that then there will be no way to know what was causing the vibration.
OH yeah, my car isn't stock, Good's springs with 1/2" spacers, soon to be
removed spacers as the body sways too much, rear coil over shock conversion,
F&R up rated sway bars.
So what to check, check the bolts to all the axle shafts, u-joints and
axle splines for wear.
