Quote: one thing i did notice when i put the drive shaft back in there was a bout .010 to .015 side to side play where theu joint sits in the yoke.
I mensioned that you should check the rear yoke for spreading [ twice ] on page three, Why are you changing out the front yoke if its destroying the rear u-joint??? There's probably more slop than that also.You might want to try turning thr rear yoke by hand to see if the pinion goes in and out some , if it does it might be the reason it doesen't vibe in reverse
i did put a new billtet yoke on the rear and the ujoint is a nice tight fit now, as for the rear it self i tried another set of gears, this set is a 3.91 with the same results as the 4.30's and the 3.23's
