Hi,

I have a 1981 Corvette that I recently installed new Spicer 1330X U-joints into the half shafts. I replaced them because I had gotten a weird wobble feel from the back tire one day while I was driving it. It was almost like the tire was coming off. After some research, decided to replace U-joints.

Working on installing the half shafts back into the car and ran into a strange issue. I got the passenger side half shaft installed and tightened all the strap bolts down. I moved to the drivers side an installed the strap bolts onto the yoke/wheel bearing. When I went to install the strap and bolts on the side attached to the diff, noticed that there is a pretty good gap of maybe 1/4 inch or so... and the U-joint does not sit flush against the yoke on the diff side. Almost as if the half shaft is too short?

I then pulled the one on the passenger side that I just installed just to try to install on the drivers side and same problem, about a 1/4 " gap from the U-joint to the yoke.

Anyone experience this or has an idea what it could be? Could it possibly be the wheel bearing? It turns no noise and don't see a wobble when turning by hand.?

Frame is straight and it always drove straight and true for the ten plus years I have owned it? Seeing that the diff is bolted to the cross member, I don't see that it could have moved? Stumped...
