Rear Axle Seal & Bearing Job

[arcteryx]

Thanks for the reply Tim. Yes I did use a thin layer of grease, but won’t next time. It seems to slide out easily which is causing part of the problem. I think this is one of those things that may get done once per ownership, if that, so information seems harder to find vs the front per se. Appreciate the video.

Nissan- I have 2 long/left side axles pulled, both do not have any movement in them. I went ahead and ordered a new bearing and housing from Mr T, should be in early next week. I will measure both bearings to see if there is a difference with those buts showed they were the same.

I wonder if the bearing housing stretched and the housing is a max 2 time reusable item (initial from the factory and 1 more to do this job), similar to UCAs. The first time I did it I don’t think there was any movement but the seal did not stay due to the grease so I redid it. Then the second time I pressed it caused it to stretch which are the results I am seeing and brings it to 3 times being pressed. That is my hypothesis now anyway. Will report back.

@Timmy65 (or anyone else).

First, good video, both parts. I did order the full set from Duane and it has worked great.

I am running into a problem- when I seat the outer seal, it ends up moving when being pressed in. There appears to be play in the bearing/bearing housing, which is not a pressed fit, and the bearing slides in the housing. The pic shows the gap when the bearing is pressed on as far as it should (where the snap ring indentation is), but the seal is up in the oil slinger. The video shows the play when I lift it up with my feet (can't record and lift . Everything is pressed in except the retainer/abs ring which is the last thing to press.

Perhaps the play is ok and will tighten up with everything installed, but the concern is the seal may not seat correctly then. I first did this after putting pressing everything on and torquing the 4 axle bolts then noticed the seal was not straight, so I redid everything thinking I may have made a mistake. Second time, same result. The only other thing I can think of is I perhaps I put too much axle grease on the base of the gasket? It was a thin layer thinking it would help seal it and make it stick.

Thoughts?

Normal for the bearing to be kinda loose fit. I installed 3 of them. All the same. Not sure why you're seal wouldnt stay out though, I had to hammer mine in with seal tool.

To update this, I did get an Toyota label bearing and bearing housing and successfully put it all back together.

I attribute my issue to 2 reasons:
1) I used (too much) grease initially. This time, I did not use any grease when pressing the bearing into the housing nor did I use any on the the axle seal. The bearing was slightly loose but not enough to cause the movement I saw.
2) The bearing housing was stretched from pushing in the bearing multiple times. I do not have calipers that measure the inside lower part, but this is my theory.

Additionally, the Toyota label and Koyo bearings are identical in all aspects including size, caliper measurement confirms this. I went ahead and used the Toyota label one since I had it, but when I do the other side I will use the Koyo label and the existing housing without grease.

Again, thanks for the input, hopefully the above will help peeps in the future.

I love this forum! I'm just about to do this job in the next day or two. Thanks for the good info!
