Ok so because not having the time and it being easier to pay someone at the time I paid a shop to do my leaking axle seals as well as new shoes andMobil1 fluid change . Well I got it from them and within a couple of days I noticed poor breaking. i pulled the wheel and drum and just as I thought it was still leaking. I took it back to the Indy mechanic and he re-did both sides. I then got it home breaking was awesome and no signs of leaks. I did the rear breather mod and my breather was in-fact completely plugged up. Now turn to today I am on my way home today and notice breaking wasn't the best so stopped and bought some more break cleaner and when I got home pulled the drivers side wheel and drum and suspicions confirmed again its leaking!!!!! So cleaned it all with break cleaner put it back together. I don't want to take it back to the indy that did it the first 2 times because he apparently can't do it right.
Now the question

Is the switch to MOBIL 1 to blame?
If I do it myself can I pull the axles with brake shoes and components intact just 4 bolts to axle and ABS bolt and brake line?
Anyone in the lower Michigan area done this want to come over and drink some PBR and supervise?:biggrin1:

Make sure your axle breather vent isn't clogged. The heat built up by movement can cause the seals to leak. My buddy just went through this problem on his Dodge rear axle. Ended up that the breather was plugged with dirt and oil.

Did you have all the axle bearings and related parts replaced or just the seals?

a shop did my first axle seal replacement, and within a few months it was leaking again. I completely tore it apart and replaced everything myself. I found that the shop had badly gouged the seat where the seal sits, and the used low-quality non-oem seal. I carefully sanded/polished out the gouge, and replaced with an OEM seal, and 2 years later still no leaks.
 
Good to hear you replaced the breather.

All OEM parts used? If the inner seals are NOT OEM, get OEM ones. I learned this the hard way.

When I switched to synthetic mine leaked through on one side. Went back to regular gear oil and didnt leak. Not saying that is your issue and I know a lot of people use Mobil 1 and don't have issues. I think as long as you change your gear oil regularly, I think normal gear oil is completely fine. It shouldn't be leaking, especially with new seals. Maybe they didn't use OEM parts? I'm actually just finished one side of my axle with this problem, put it back together and then I noticed the wheel cylinder leaking afterwards as well. I'm watching to see if it leaks.

Yes you can disconnect the E-Brake, brake hard line and take the 4 bolts connecting to the the axle flange and pull the axle shaft off with the all of the brake components intact.
 
Grease test will confirm the proper position of the retainer. As another member said, make sure there's no gouges where the retainer seats. Mobil1 will not cause your leak. Use all OEM parts, especially the seals. To remove, do all the things you said and you have to remove the Drum brakes and disconnect the bell cranks. Super easy way, I found to remove the rear brakes is to remove the lower spring and remove the 2 set springs holding each shoe on. Then just spread apart the shoes at the bottom and maneuver the asy away from the backing plate. Just make sure you put it all back together the exact way. For example, the E brake cable that connects the bell cranks to the one shoe rides in a guide. Also, make sure to properly adjust the shoes when done.
 
I know they were supposed to use Toyota seals because I got them. I have an extra set that I ordered but then they didn't come in on time so the Indy was supposed to get them from the dealership but who knows.
 
Does anyone know first hand if Mobil 1 will leak because of the smaller molecules of synthetic or is this a wives tale?
 
I had a shop gouge holes under where my inner seal sits (first time) and that was the cause of my leak. after the 3rd time of replacing it myself with new bearings i sanded it down, added some grey gear oil rtv and it hasn't leaked it 3 months knock on wood
 
75W-90 Syn isn't supposed to cause leaks, and I'd rather use syntetic in gear cases.
But, after my own personal epic five-redo dealer rear axle seal job two years ago, I'm haunted by the ghosts of anything that is even rumored to cause trouble with the rear seals.
So I use conventional 80W-90 in the rear diff. I change it every year anyway, so it never gets old.
 
x2 on bad bearings. My local Toyota always changes the bearings with a blown axle seal. Otherwise you find yourself doing it over and over, which you are experiencing.
 
So I just talked to my Indy mechanic and he did not use Toyota seals he used some national seal brand seals. [emoji31] so what do you guys think ?
 
National, while a good brand for parts for American cars (used by me frequently), should NOT be used as an inner seal replacement. OEM, nothing else.
