Jack it up and see if it does it on the stands also. A cv joint or hub going bad without road pressure might react differently when driven. Not really sure.

When I had my tranny rebuilt it had a slight shudder on acceleration so the shop put in a new valve body.

3:69,typically are more unreliable of a gear set. 2.93 being the steongest available 3.29 being the second best

No one has yet to be able to answer why the chain drive is somehow weaker with different sprockets. IMO its just a matter of statistics, less people use the 3.69's and they are typically higher powered car's so they have a higher failure rate. Doesn't give it more or less strength then the other sets, the drive chain is the same regardless.

I believe they all are the same length the 3.69 just puts more stress on the chain I guess I'll just put another and hope for the best

Simple, think about a bike gearset, 1st gear is tall and big, which if you figure in torsional forces and everything else is more likely to shear and cause loading issues side to side on the chain then let's say the small 7th gear would, as its less material and doesn't have as much ability to fail. Hence Why the super high power cars are on 2.93 or the 3.11 gmr set.

Question, so a rebuild with those chains would be much better obviously, but is there anything needed to support those chains?
