Recurring Axle Seal Leak

[Hopeless Diamond]

After I did both of mine, the passenger side had started leaking again (service records show it was replaced twice by a dealership). I used new retainers (don't remember if I flipped them), applied FIPG around the axle before I pressed the inboard retainer on, and also applied it around the axle housing before I installed the seal. Made sure to clean off any excess. Have put ~20k miles on it since, over 10k of those miles were from Seattle to Cabo, twice. Lots of hard miles

I flipped the retainer many years ago on both axles and have around 150k using this method and no leaks. Didn't use rtv, so can't comment on that. If I had to do it again, I would still flip the retainer using Toyota seals. Good luck

Sounds good. Thanks for the input. Now I just need to see if my 12 ton harbor freight is up to the task.

I flipped retainers (and used new ones) and used the updated seals. No FIPG and I've got about 9k and 10k miles I think on the job (was slow getting both sides done). Done a lot of offroading on them. Just pulled the ABS sensors not long ago and everything is still bone dry in there. Pretty sure I was the first one to change to seals too, everything seemed to likely be original (old style seal and OEM bearings with very faded grease seals). I wonder if things get screwed up on this job in the past if it just basically hoses the axles unless you do the FIPG.

I saw on a different thread that you bought the bearing from napa. I was looking on there and couldnt seem to find one fir the wheel bearing, do you have a part number or a link to the one you bought?

I had mine replaced at a shop, first time it leaked, second time after getting "fixed" it leaked. I was told there was a groove worn in the shaft but have not looked any further into it yet.

Planned to swap a locked rear in but considering selling now. 2020 TRD tacoma looks pretty good and I bet the seals don't leak!

Is it safe to assume the only difference in abs and non-abs axles is the abs uses two retainer instead of one for non-abs? I'm looking at this kit and the non-abs only has one retainer in it. I was hoping I could reuse one of the retainers closest to the bearing and use a new retainer on the seal side. Looking to replace the bearing and retainer plus a new factory seal. I cant imagine the retainers are different for non-abs vs abs. Mine is an abs axle.

I think the retainers are the same for ABS and non ABS.

Thanks for these part numbers

I was able to get the Nachi 6308-2NSE bearing for $26 free shipping at
6308-2NSE9 NACHI bearing 6308-2NSE seals 6308-2RS bearings 6308 RS Japan 6308-2NSE Nachi bearings [6308-2NSE9] - $26.00 : JSB Great Bearings, online radial, pillow block and miniature bearings store

Seemed of same quality as stock and stamped made in Japan. Bought retainer on ebay for $16 and my local dealership had the seal for under $7. Not too bad for doing a bearing replacement. Now cross the fingers it doesn't leak again

Did you check that the rear diff breather was clear? A clogged breather will cause rear axle seals to leak faster than Sonic the Hedgehog can run. And that's fast!

Good luck!

Yeah I've actually modified mine and all is clear. Good advice though. My seal was riding on bevel part on the retainer. I flipped the retainer and used FIPG on the retainer and seal. Did the sharpe test and mine isnt exactly riding in the middle of the retainer but I think it will be enough which kinda surprised me since I went 5mm from the shiny part of the axle.
Hopefully this fixes it for good.
