DaleB Dale I can give you a quick list
Bad universal joint
posi rear carrier locking up or unlocking
loss control arms or bushings have play, same for solid metal bushing
play in the trans internally
back lash in the rearend.
output shafts twisted in the rearend
play in the hub bearings
Transmission angle and rearend angle off, cause binding
Yoke on the trans binding
no lube in the pivot joints out universals
Heim joint binding from no
oil or the grease is gone from joint
The frame could have a bad weld and be cracking
The list can go on for another 15-20 lines, I think you get the problem
If the car is abused, any part of the drivetrain or suspension could cause the problem. You need to find a mechanic to isolate the problem. They have chassic ears to help locate the problem for couple hundred dollars.
It could also be nothing more that the body on the frame at one opf the mount locations. Bottom line, I don't know the price of the car but would want this problem FOUND if not fixed before buying. The car has you in love with it and a problem that could kill you. Cracked frames do happen. I am not trying to scary you but this is real. Get some one to look at the car.
Also get in writing from owner that this car is solid built with no problem. If owner doesn't do this, I would walk away and look for another prize. JMO. Rick L. Ps it's like a box of cracker jacks, you never know what the prize wil be.
