I am not to sure If this has been posted yet or not. But last night I as I was putting together my diff. I noticed that is was very similar to an X-ray diff.. so hmmmm.. As I was reading the instructions and it said tp put grease on the thrust washer then place the thrust balls on there I thought that is retarded
.... And I noticed that it appears to be the same size as the X-ray thrust set up... so I used an old Xray one.. It worked perfect. http://www.axiommotors.com/thrust-bearing-p-132.html
It is so smooth. Just thought I would share.
