Re: Bits of brass in a 32 900 differential

Tom,

I've used the sleeve option on other ball bearing before when a source was not available. I try to use a slightly smaller bearing so I don't have to modify the original casting. If the correct bearing is found, or made in the future it can be put back in.

As long as the dynamic axial and radial load rating is equal or better than the original bearing you have, you should not have a problem.

Did you mark the location of the spider X that is captured between the two housings? This is the part the four spider gears fit on.

Also the two differential halves that capture the spider should have been marked so they would be re-assembled in the same location. If you didn't you may want to try different orientations to correct the bind in the spider gears.

I don't think excess torque is you problem. Try removing all the spider gears and reassembling them one at a time. You don't need to full torque all the nuts. Check for free play as you assemble each gear and tighten, then loosen and add another in.

The side gears the spiders mesh with, the ones the axle shafts fit into, should have been marked and re-installed in the same place they were originally.

Any dirt, chips, etc. between these side gears will cause a bind in the spider gears because it will force the side gears against the spiders.

I wouldn't worry about the mark on the I.D. bore of one of the spiders, as long as it is not a crack. These gears only turn at slow speeds to compensate for the difference in revolutions between the rt. and lft. wheels.

Regards,

Dave
