[6pack] rear end vibration

[Ian Breyer]

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.
