After more that a few tries I finally got the right combinations of shims under the rear pinion bearing race (cup) to give me a reasonable wear pattern on the crown gear.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Lacking a race extraction tool I used the brass bar on the left and a small maul to remove and install the race. Not the best, but there are crescent shaped cutouts in the differential casting for this type of removal. I used the same tools to replace the differential side bearings which I also had to do a number of times to get the spacing right for a good wear pattern and the correct backlash.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

I picked up this unit to remove the side bearings on Amazon. I had to remove the bearings a number of times before I got the wear pattern and backlash right.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

It is recommended that the housing be only spread apart .020. Rather than open it up to the .020 I decided to just do the minimum by only going enough to cover the .008 side bearing preload required<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

With .045 shims on the left and .015 on the right I was just able to slip the TT unit in the housing (without the spreader) – snug enough that it took a pry bar to get it out. I figure there was likely .002 clearance. Just enough to allow the unit to slip in place with a few taps from a rubber dead blow hammer. The manual calls for .008 preload on the side bearings. So I added .010 (.002 plus the .008) to the left side and then had to move .005 from the left side and move it to the right side to get a good backlash. I needed to spread the housing a little over the .010 for the TT unit to slip in. That would be less of a spread than the .020 recommended.<\/p>\n\n\n\n

The TT unit slipped in with some help from the dead blow hammer and a final check on the backlash showed about .004 – recommended between .003 and .006.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Believe it or not the next thing I did was to dissemble the TT unit and the pinion. With all the work I did I expected that there would be some brass, metal and paint slivers throughout the assembly. Also I used a lot of chassis grease to hold things in place during the operations.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

I cleaned everything up using brake clean and a tub of clean parts cleaner and then blew it all dry.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Same for the housing.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Pinion back in place with lots of hypoid gear oil over everything to stop the raw metal from flash rusting.<\/p>\n\n\n\n

The TT unit being reassembled with hypoid gear oil over all and in the side bearings.<\/p>\n\n\n\n

These are the two thrust blocks that fit in a hole in the centre of the cross arms. I was at a loss as to how to hold them in place until I realized that they are held together with a 1\\8″ roll pin. No worry about them falling out when the axles are finally put in place.<\/p>\n\n\n\n

A fine bead of sealant for both sides of the gasket.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Gasket and cover both in place aided by two guide bolts.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Bolts in finger tight. Tomorrow I’ll torque them to spec and touch up the paint ready for install over the winter sometime.<\/p>\n\n\n\n
