I just received Glenn Chaffins' orange front and rear axle MTFCA book... what a plethora of useful information. Best money spent so far! HOWEVER, theres a gray area between the 25 and 26-27 new and improved model info...
The book and my past experience has proven that theres supposed to be 2 nuts on each rear radius rod. One in front and one in back of the U joint housing to adjust perpendicularity (whew!!) between the drive shaft and the axle. This unit came with TWO... one on each side. It seems the radius rod pulled up against a shoulder making for NO ADJUSTMENT and possibly distorting the diff housing. Anyone care to comment on this?
Next step is to order a spool bearing kit. Adjustable or not? Comments? Seems the adjustable is the way to go but does cost a bit more. Also got a new drive shaft bushing. With the spool kit does the thrust collar need to come off? ws
