[6pack] rear end vibration

Like Aaron stated check all of the rear end assembly. In one of your
posted you stated a difference in side to side measurement. This could be
caused by the bushings in the trailing arms going. A check would be jack the
car up and with a pry bar against the frame see if you can move the trailing
arms.

Ian,

I havent seen anyone encourage you to check out the differential
mounting pins, especially the right front.? The symptoms you describe could be
caused by a cracked mount if it has gotten really bad, especially letting your
foot off the accelerator.? A good inspection of the entire rear end is a good
idea at this point.? Let us know what you find.

Hi all. I hope you guys can
provide some insight. 

My 72 tr6 has been shaking pretty bad. It seams to be
be coming from the rear of 
the car and is most noticeable when doing 50mph or
more especially when I let my 
foot off the accelerator. The car also seams
very jumpy around town when I hit 
bumps. Incidentally it started after I had
the rear wheels off to bleed the 
brakes. I thought maybe I hadn't tightened
the wheels properly so I took them 
off and retightened them. I have checked
tire pressure and the tires are pretty 
new so I don't really think this is
the problem and that the timing of the two 
problems was just a coincidence.
When I had the wheels off I took a look at the 
rear shocks and springs. They
are old but nothing looked broken or disconnected 
as far as I could tell. I
wasn't able to check out the u-joints or rear end.

I am leaning towards
having the rear suspension rebuilt as I have all the parts 
on hand. 

I can't
completely rule out the front end as there is some vibration in the 
steering
column but it feels to me that this is being transmitted to the 
steering
wheel from the whole car shaking rather than the front end being the 
problem.
I have driven cars with alignment issues and this feels different to 
me.

Any
insight would be much appreciated.
