Rear axle bearing washer?

[myquestoyota]

I had a SOR rear bearing set on the shelf for years and decided to replace the bearings because I was replacing the differential and had it apart. I removed the old bearings and seals and replaced the bearings but then saw two "axle washers" in the kit from SOR. There were no washers in my axles and I don't see them in my FSM. Any input on these washers?

Full floating axles are a different design than semifloating axles. The early FJ40 axles are semifloating. This design requires the axle outer flange to be bolted onto the hub to retain the driveshaft. Full floating axles have "C" shaped retaining washers next to the spider gears to prevent the driveshafts from moving outwards under load.

I don't know, but I'd guess the SOR kit was for both types.

Are the " axle washers" shaped like a C ? Since you have taken the axle apart I assume you are familiar with the C clips and the " axle washers " are not the C clips ?

On our 1970, the "washer" was closest to the differential, then the bearing then the seal.

The washers in diff between side gears and housing are thrust washer and used to set spider gears and side gears clearance. They come in multiple sizes.


You also have the C clips and flange bolts backwards.

I do have an interesting early Land Cruiser that has a custom hub made to eliminate the C clips and make it a full floater with a single pressed on bearing. Those have a washer.

I assumed he was referring to the "C" washers, since he couldn't find where to put them in his axle.

As you can see in the diagram on this page the washer goes in the end of the axle housing before installing the bearing followed by the seal.

I believe the washers were omitted in 1974 and later models with semi-floating axles.

Up until then, the rear axle bearings included a race press-fit on the axle shaft. I think the later axles used the same bearing, but the axle diameter under the bearing was increased to eliminate the race.

I always thought the washers were to help hold the axle shaft up off of the seal to prevent it from damage when sliding the axle into place. Maybe not.
