i have a vibration at 40 mph that i just can't find the cause of.i have had severial motors put in and out of the car,rebuilt the transmition,rebuilt the front end,rebuilt the steering all the way through.all of this work has not done any good at solving the vibration problem.all that is left is to remove the rear end and start rebuilding from top to bottlem but before i do that i want to run it by you guys to get your opinion.there is no noise at all from the rear end.it all apears good except the rear axel keyseats are a bit lose but i keep the rear drums tight to prevent anymore wear.i just don't think the vibration is found there.i did put in a new universal jount when i overhauled the transmition however from that point back i have not touched anything.what is the runout spec.on the driveshaft if i decide to take it out and check it?
