Not sure about the 'wobble' issue you guys are talking about. I'll check it tomorrow at work and find out what's going on. I'll have to check on the diff thickness' also. I just built a 'store bought boxed kit' to see if everything was good and it was.
Tony do you remember this post? Diff problems way back before the first of the year. Let's see the Birds were in Feb. So how long does it take to research a problem. The post before this one that I quoted was from wannabe asking about the problem There are more if you need me to refresh your memory.
