I run a spool in my S 60 with no issues. The only time I notice it is turning tight pulling into a parking space.

Was that spacer and beat up shims on the pinion? If so whoever set it up did not do it right, the pinion was moving in and out, so the gears are plain junk. If you say the bearings are good I would sand roll or dremel them out to make them slip bearings so you can get the pattern perfect, and buy new shafts, new R&P, new bearings and be done for about $400. Drag radials did not break that suregrip, it was put together wrong, factory service manual for that, carl jantz u-tube to learn how to slam a dana 60 setup in 5 minutes with slip bearings. If I recall the new shafts will not have the hole in the middle, so if you have tapered axle bearings you will need to drill them, and add the thrust spacer. If you have greens then you do not need them. One other thing would be if you have aftermarket axles make sure they are not to long and that is what broke the shafts.

The damaged shim was in front of the pinion spacer. It may have been beat out by the pinion moving back and forth, but the other shim beside it was okay, so I think that the shim slipped out of place during installation. Just a guess on my part.

I know that the drag radials did not play a role in this mess, I only mentioned them as a point of reference on my question about spool vs Sure Grip.

And it has the green bearings with aftermarket axles. So that is a good tip to check the length of the axles. Thank you.

Had dana 60 on my mind, sorry as I see it is an 8-3/4. You only need one slip bearing, well worth the time, you will never set a rear without one after you use one.

Close inspection of the shafts and axle ends revealed marks that I believe show contact with each other. Good catch, I really appreciate the heads up. I will definitely shorten them.

The thrust block moves about 3/8", so half that is 3/16", that would be the minimum clearance, I would do 1/4". As long as you have full spline engagement you can do more.

I prefer to polish the pinion to reduce the rear bearing press fit enough to install and pull the bearing with just a light effort. Not sloppy, I still want to use a press. The front bearing is made to just tap on and off of the shaft. I want to use the same bearings for set up that will be used in final assembly.


If the results don't match the theory, change the theory.
