Well this is a nightmare.
I guess my first question is are they left and right side spacific?
I took mine in for a rebuild and this has gone soooo south.
I went to install them and the one was fione, but the other had about a 1/4\" gap between the shaft and the diff housing.
The shop first told me they were the same, but now he tells me they are side spacific.
Waht a pita........MAJOR.
