Shop manual: Link to bearing replacement. ....You will need a retainer plate gasket between retainer and backing plate. Link to Gasket.

The bearing is a self contained unit with the race included. The only way the race comes out seperately is if the bearing has failed badly.
The outer race has an o-ring between it and the housing.

I have access to a press, but I don't have the special support plate J-5741 shown in the manual. Are there any alternative recommendations? It seems like the bottom support in the press should be contacting the bearing inner race directly. If it contacts the bearing retainer, it would probably work, but might damage the retainer.

Thank you

Larry

J-5741 is a bearing splitter. Link to bearing splitter. The splitter can grab the outter race of the old bearing as your not concerned about damageing it.

The old bearing are removed by nicking its retainer collar with a cold chisel to expand it then the bearing and collar are pressed off together. The new bearing is pressed on by its inner race and then a new bearing retainer collar is pressed on behind the bearing to lock it in place

55 & 56 bearings are sealed on both sides and permanently lubricated by their own grease but 57 bearings are only sealed on the outside and open on the inside to be lubricated by the differential’s gear oil.

Not marking the U-joint and which way you put it back is not a problem. Like installing a new U-joint, it doesn’t matter. Drive shafts are balanced without the transmission or third member and U-joints should be neutrally balanced.

The type of bearing “separator” shown are commonly used on hydraulic presses to press things on or off shafts and can be place up or down depending on application.

By turning the separator flat side up and adjusting it close to the axle’s diameter the bearing inner race will set on the separator and can be pressed on or off the axle.

I can't get my splitter between the bearing and retainer. The shop manual shows the splitter between the flange and retainer. The retainer only contacts the outer race. Link to shop manual.

Damn, welded ring! Be careful with removing that.
Just press against the outer retainer cuz' you're not going to re-use the bearing.

That welded collar would make me think that axle had had previous problems.
