    So I've spent hours online looking into this...looks like its a common problem and a hard one to fix....boo.

    Anyway. The inner seal seals the axle housing, the outer seal protects the bearing from external threats like water and mud. Hopeful an inner seal replacement and breather fix will work.

    Mine started leaking a few years ago and then finally became a problem when the oil soaked onto the brake shoes. It failed inspection, so the shop did the work for me. They just did the inner seal.

    You probably will be buying a new breather when you do the relocate. Mine was clogged. I cleaned it and it opened, but when the new one showed up it had was twice the breathing volume compared to the old cleaned one. Glad I found this forum as it gave me the idea to do the breather and extension. The mechanics that fixed the seal did not mention to replace the breather.

    Definatly replace the breather. And it's not a hard job, just looks like it. If you do the seals only, you dont need to take the brakes apart. Just pull the drum, disconnect the ebrake cable and hard line, then the 4 14mm nuts holding the backing plate on.

    Well, I think I found diff juice on the ground, under the tire the other day. I looked at the backing plate and it looked a bit oily, but only up top. But the wheel definitely showed signs of leakage from somewhere considering I swapped front to back after doing everything. I haven't gotten pics or taken anything apart yet, but this sucks. Toyota will want to charge me for their bearings/seals/everything and wants the truck there so they can charge me labor to remove/repair/replace, or try to take it back to the worthless fuck I drunkenly ranted about and tell him to fix it. I'm not exaggerating, amarillo has 0 competent toyota axle bearing pressers. Toyota itself is an elitist snobbery who cant do it with the axles out of the truck, or deal with the 2 cousin fucker machine shops with bearing presses big enough, but dont understand anything other than big block chevy. I dont know what to do, but I'm NOT paying toyota a grand to fix this. I wont have pics for a bit, seeing as how I'm drunk sitting on Grand Lake in Tulsa right now, but can have some up on Tuesday. Just drunk posting/ranting for now.

    It's to bad I dont have a little more time to make a press that could be passed on to everyone doing rear axle bearings. Just made this up for work.

    That's some impressive fab work.

    Regarding a press tool for the Toyota, somebody already makes one:

    https://www.ebay.com/itm/202596609234

    It works on these vehicles:

    4Runner: 1984-2002. Generations 1, 2, & 3
    Tacoma : 1995-2015. Generation 1 & 2
    Tundra: 2000-2006 Generation 1
    T100: 1992-1997
    Hilux: Most older years. Check first
    And with an additional $45 adapter he sells, it will work on later gen Tundras, Sequoias, and FJ Cruisers.

    Here's the video review of it by Tim the Toyota Toolman:

    https://www.youtube.com/watch?v=R-c2x3F8DU4&feature=youtu.be

    I made the decision to buy mine based on Tim's video.

    You need to have a shop press -- like this 20 ton press from Harbor Freight.

    The tool works really well.

    I'd be open to loaning it out. We'd have to have a system similar to the auto parts store loaner tool program, where you basically buy the tool, then get a refund when you return it.

    For $168 that would be cheaper than paying anyone else to do it. I might consider that.

    Sorry to heat that BMF. I've also watched TimmtyToolman's video and thought it was very informative. But I'm not sure you need a press and all the specialized tools that he uses. This video from ThePracticalMechanic does it with just a piece of steel pipe. Now I know a press would probably be the smoothest, but he doesn't seem to be beating on the bearing with much force to get it into position. In the comments he says the pipe is 1 5/8 ID. Good luck.

    100% with you BMF. It drives me insane when we've done the homework and know exactly how a job needs to be done but we don't have a 50 ton press in the driveway to do it with. Then we have to find a shop willing to do it, give them parts and instructions and still they fuck it up for $120 per hour.

    I would go back and tell them that they didn't do it right, do it again free. Then again I understand the sentiment of if they fucked up why waste time going back.

    I had to look high and low to find a shop to press my front wheel bearings. Toyota wouldn't touch it. Most shops said they would only do it of I bring in the whole truck so they can test drive when it's done, like I'm gonna pay labor for all that disassembly and reassembly hoping they do it all right. When I finally found a shop that wasn't scared and was competent I felt like I struck gold.

    That is a very well thought out tool. What I was thinking would be similar but you could do it without the press. A press takes up a lot space but are nice when needed if you do a lot of bearings. I belive if you extended the tube roughly a foot past the axle you could use a hollow single acting ram similar to this Mophorn 20T 4" Hydraulic Cylinder Jack Hollow Single Acting Hydraulic Ram Cylinder 100mm Hydraulic Lifting Cylinders for Riggers Fabricators (20T 4" Hollow) https://www.amazon.com/dp/B07K7LZLJW/ref=cm_sw_r_cp_apa_i_IEa.Cb87H5W3H
    for removing and installing everything, it would take a little time to think it out, the benefit would be that it could be in one box and shipped without breaking the piggy bank. Looking at Tim's garage looks a bit cramped like mine.

    At this point I'm almost ready to sell it. On top of this 316k mile truck, I have 3 SHOs that I need to drop the subframes and swap a lot of shit around, a full time job, 3 kids, a GF, and I'm doing 9 credit hours in 8 week classes this summer. And I'm here at the lake getting shitty. :burp:

    I did this at home for freeeeee
    Pulled the axle after i found out the bearing was bad, from the seal going bad. Replaced all diff fluid twice. Did all seals



    Sooooo
    For the bearing and ring on the axle i simply found a old board and bashed the whole thing up and down while holding the backing plate it eventually came off. To get everything on i used a piece of 2 inch black iron pipe from work and used it as a slide hammer to press down the bearing and rings.

    It was spectacularirly redneck and we had some good times doing it

    That's how the tech in a professional shop installed the new bearing in the video above -- so if it works, good on you. Well done.

    Did you confirm seal-to-race allignment with grease or a sharpie? It makes a big difference on the longevity of the repair.

    @bmf4069 thanks for the write up. This thread has given me the courage to do mine. Driver’s side is leaking. Found a “reputable” (so they say) shop in town to press new parts on the axle.

    Would you just as well do both sides while I have the one off already?

    So I'm thinking about buying the adapter thingy on fleabay. But it still requires a tall press so it leaves me in the same situation of no press/cousin humper machine shops. As an electrician I have acces to all sizes of rigid, intermediate, and emt conduit.

    So my question is how many tons of pressure do the bearings take? Can I do some extreme rigging and put the axle against a support beamon the ceiling and use an 8' or so length of pipe with a 3 ton car jack? And what would I use to measure the proper press depth? I'm thinking caliper something but cant remember...

    Most of the utubes I've watched show DIY guys pressing the bearing off with a Harbor Freight press, maybe 10 ton or something similar. One video the guy doesn't even use a press. He just bangs the axle some plywood to free it from the backing plate. Then he cuts the bearing and retaining ring, finishes it with a cold chisel, then rams a new bearing and retaining ring on with iron pipe that fits over the axle. Sure you have to spend an extra $50 for new retaining rings, but you save not buying a press you use once a year and a ebay adapter gizmo you use once a decade.

    I've wanted a press for a while, so to me, buying the press was a pro, not a con. The press is only $150 from Harbor Freight. Will come in handy for future bearing and suspension work. I suspect mine will last the rest of my life.

    I wouldnt mind having a press, but I dont have a garage. I have car parts and tool over, under, and next to the kitchen table. As cool as it would be, I dont think even I would be ok with a shop press next to the kitchen table too.

    Well, you clean your valve covers in the dishwasher... so I figured you might be up for a 20 ton shop press next to the fridge. :)

    If you were in Maine, you could come over and use mine. Would only cost you a few beers!:cheers:

    Also remember when it comes to installing bearings if you live in the northern states you can place the axle outside (or big freezer) a few hrs then heat the bearing to 150 F to 200 F and they should almost fall into place.

    Do you have a yard? Just stick it outside.

    Not to mention, you can use it to make your on AK47s.

    Thats what I got mine for....oddly enough I only built one AK with it but I've pressed quite a few bearings.

    I went for round 2 on the rear seals this last friday. This time I had the axle tool thing and we measured the bearing retainer to make sure it seats good. I didn't get too many pics this time as I was in a rush. Still took every bit of 7 hours.
    Also, I hate drum brakes. Such a pain. I nominate @empty_lord to figure out a way to put a sequoia axle under a tundra. If people can SAS the front end, a SAS(sequoia axle swap) for the rear should be feasible.

    So yeah, it's pretty straight forward. Just pull the brakes off, pull the abs sensor, pull the wheel cylinder, then the axle comes out. We cut the retainer of and were able to pry the abs ring off and repress it since my dumbass only bought one bearing kit. Fortunately, it has 2 retainers in it so we made it work.
    After that we used the red piece as a stopper and pressed it all back together. The instructions on the tool thing aren't very clear for tundras unfortunately. Then I fought them back in, wrestled the new shoes on, and semi adjusted them. I still need to bleed and adjust the rears. It was hot and I was well past beer thirty. Anywho, hes some pics for y'all.

    My drain plug is very shiny, it worries me. You can see it on my hand too.
    20200703_115258.jpg

    Drivers side covered in oil again.
    20200703_120150.jpg


    Pass side was fairly clean, except for one thing...
    20200703_120202.jpg

    This is all the brake dust in there. I've driven maybe, maybe 1000 miles since putting them back on.
    20200703_120212.jpg

    Oily drivers side.
    20200703_120222.jpg

    Drivers side abs sensor. Notice the shiny streak? Wtf?
    20200703_123820.jpg

    So I pulled the pass side to see if it was leaking. Yup. And the same shiny streak.

    My other pics aren't popping up on drive. I'll reserve this incase I finger it out.


    Ok, so it's only giving me 2 more.

    Getting the press set up.

    Retainer cut off the left axle.

    So pretty much we knocked a stud out and pryed the abs ring up. We then slid the red piece from the first pic in and ran the ring down to it. Then pressed the retainer to it. Put the stud back in and off we went.

    BMF, glad to hear you got your bearings sorted. I remember your frustration about six months ago when the local shop pressed the bearings in too far. After you sweat out the thirty beers, please upload some more pics of the proper bearing position on the axle. In my opinion we cant have too many reference pics for this job.

    If you want a sequoia axle under a tundra all you need to do is strip all the sequoia suspension parts off and weld on tundra perches and shock mounts...

    Whoa! Way too much dust for only 1k miles. Glad you are getting this finally sorted as, like you, have been through knuckle draggers without a clue doing hack bearing work.

    The real test will be in about 200-500 miles of driving to see if you got it right this time. Did you do the grease test on the inner retainer seal?

    I’ll post up a pic of my oiled up ABS Sensor for others to see. Didn't have the silver, but had the rustys from maybe a bad passenger bearing that isn’t noisy yet. Or maybe water intrudes somehow? The oil was trapped in the Sensor/Retainer part of the hub and had no signs of drips in the drum. I’ll pull my Sensor tomorrow to see how the Seal Replacement from a few weeks ago is holding.
