I installed a 8"vibration at certain speeds. trac-loc pig in my car this weekend. the car now has a vibration and it happens when I'm letting off the gas and it's not as bad when I'm on it. the drive shaft seems to short now. it used to stick ou a bit past tail of the trans and I mesured it to see what it was. 2-3/16" is the distance between the tail of trans and the front of the u-joint. also the rear seems to be very tight(binding a little) a round corners. is there a way to see if the rear is too tight without removing the 3rd member? or is this normal for a posi?
