I have the same problem and will try this fix in the coming weeks. Where you able to replace the parts yourself or did it have to be done by and experienced mechanic?
Thanks
I changed it out with hand tools, pretty straightforward - there are several how-tos for 4runners etc that are similar on YouTube. You may struggle to get the old seal out, I found it helpful to have a 2-pronged seal puller handy. It’s also hard to seat the new seal, I ended up using my axle socket to tap it in place gently. Might help if you put it in the freezer beforehand.
Thanks for this.
I think I may have to do mine sooner than later.
Any other additional suggestions in terms of tools that I need and parts that I should have before even removing one bolt or nut? Your wisdom and experience are highly appreciated.
Do you have a press or a machine shop that can press the bearing off to replace outer seal? There are some posts here about doing it, along with at least one person who made their own fixtures to do the press work.
If the outer seal is not a really tight fit it can slip out when you bolt the axle back in, so keep an eye on it. Had to press mine apart a couple of times to reseat, before ending up gluing it in.

Has anyone attempted to use this tool?
Rear Axle Bearing Puller, Tone Ring Tool /Installer Toyota 4Runner Tacoma | eBay
I need to do this job soon and I'm thinking of trying to modify this tool to work with the 100. I couldn't find any info on the inner diameter of the wheel bearing. It looks to be a tad bigger than the Tundra/4Runner, ~45mm. I think the axle puller should work, the ABS tone ring installer might need to be enlarged to fit the larger 100 series ring. I contacted the seller to see what he says.

Perfect timing. That tool will work with the NEW ADAPTER plate for LC me and the seller DONALD-THE-BONALD (Duane) created. He should soon list the adapter plate on ebay that will work with his tool for a LC.
I used that tool to do the rear axle seals on my 3rd gen 4runner and it worked 100%. There are few things you want to get it right.
Make sure to follow Timmy the Toolmans video about rear axle bearing on 3rd gen 4runner using Duane's tool (that adapter plate on the video does not work with the LC).
1) Do the sharpie test to make sure the oil seal rides on center of the retainer.
2) If you have aftermarket retainers installed (OEM has nothing embossed), you will have to grind it to make it less tight before using the tool to pull the ABS ring. Otherwise the ABS ring will bend: (yes it happened to my 4runner abs ring)
Email Duane through his ebay link and ask him whether you can buy one (he is doing some powder coating on those LC plates right now). Perhaps, you can document the process and make a good engineer to prosper. You can tell him that Nissan referred you.
I ordered it. Duane is going to include the prototype adapter plate. I will post pictures when I'm done with the install. Also, FYI the inner diameter of the bearing is 48mm.
Hey guys, it was never answered - is this the full list or is there more to it? I want to order everything tonight.
I have the rear axles out to put lockers in. Mine arent leaking, but I might as well do the bearings while this is all out. I have a feeling putting the E-brake back together is going to be a *&!%'n PITA.
Bump... any help?
I would not mess with the bearing if it is good. Install OEM oil seals. IF the bearing has up and down (not side-to-side) play I will then replace the bearings with OEM bearings.
The process to get the ABS retainer sleeve to meet the oil seal is cruicial and it needs careful attention.
I'm open to anything, but I can tell you that putting the parking brakes back on is going to SUCK and not a job I want to do again. If its out now, and I am going to replace with all OEM parts (on a 230k vehichle) - are you saying I shouldnt do it because its too hard to get someone who knows how to do the job correctly?
Well.. You should do it if the bearings are worn. Not many shops know how to properly align the abs ring retainer (on which the oil seal is running). I see lots of threads on the 4runner forum where people report leaks even after rear axle seal job.
The job is not difficult at all. I did mine once without following the guidelines outlined by Timmy the tool man's video where he describes "sharpie" test , and ended up seeing oil leaking in to drums. I did it again following his Sharpe test and it worked 100% percent.
Watch his video and you will see what I mean by the sharpie test.

I have watched those videos. I dont see a sharpie test, maybe I'm missing it... but are you talking about putting the inner retainer in 'upside down' with the bevel side down? The Dr Coffee method?
I dont want to buy a press or the plate, plus I have enough projects right now. I'd rather pay someone to do this. But to your point, I certainly dont want this being done incorrectly.
Edit: I just found a guy locally that I think will be a good resource. He does these axles for a lot of the local shops. He's never done a 100 but hes done a ton of other Toyotas (he said he owns an 80). Before I even brought up the issue with the seals leaking as a result of the retainer he told me how its a common issue when people dont know what they are doing.
Now I need to double check and ensure I dont need more parts than this:
90313-62001 Oil Seal
90369-48001 Wheel Bearing
90310-58002 Axle Shaft Oil Seal
90520-44038 Bearing Retainer Lock Ring
90208-48002 Oil Seal Spacer

Looks like you found the right person to get the job done right. Yes, Dr. Coffee method.. he was in T4R 3rd gen forum and found the method!
Sorry, it is 47:55 mark on that video :
At 48:51: The axle has been inserted into the axle-housing and mounted with 2 bolts. Then they spin the axle to get the seal to ride on the retainer. To check the mating surface, they pulled the axle out to inspect. The smeared area on the shrpie mark indicates the seal is properly riding on the retainer.
You must install new Retainers especially the one near the bearing.
I think 80 series from 1996 got ABS so the shop should know how to properly set the ABS retainer to ride on the Oil Seal.

You're the man, thanks!
They've done a bunch of 4runners with ABS and he specifically referenced the retainer issue, so fingers crossed things will be fine.
Hey bud, sorry to bother you again. Is the 9031058002 part number the inner oil seal, the one that is located IN the hub itself? It looks like it to me, but the FSM has no part numbers and I cant find a worthwhile diagram on the internet to save my life.
After re-assessing the situation, the bearings feel great and i see almost no seepage around the seals, so I am going to keep the OEM ones in there for now. However the guy that I was introduced to that was going to do the bearings said I should definitely replace the inner oil seal and the associate o ring. Tracking down the part #'s has been futile. I already have 90310-58002 and from what I can tell its looks like the correct part, but I was hoping for some confirmation.
These are the inner seal and O-ring part numbers
I had a rear axle seal leaking, so I pulled the axle and replaced the seal and large o-ring. My axle is still leaking, so I dug into it again last night and did the sharpie test and found the seal was working correctly per the photos below. What I am seeing is a gap between the outside (output) flange of the axle and the plate that the bearing is pressed into (second photo). The wheel bearing appears to be new and is nice and tight, so I suspect this is the result of the axle not being pressed far enough through the wheel bearing when the rear wheel bearings where done.
