HEEEELP!!! rear axle issues!

The bearings are exactly the same, it's the position of the oil seal that is different. The oil seals are exactly the same as well.

 

so ive done all the dang research i can do. im getting pissed with this guy it will be the last time anyone works on my vehicle besides myself. ive spoke to toyota and rear every thread online possible and everything says all the hardware is the same except i need a different oil seal butted up againt the axle flange to accommodate for the larger axle housing size (the neck) that the axle slides into. whats insane is im going to get all the parts myself and will be going to the shop and installing everything myself on that particular side so im not very happy at all. i will update once the job is done and let everyone know what we found out. thanks for all your help guys!!

 

Had a day off from work and got to figure out what's going on. The bearing pictured is the one from Toyota the issue with this bearing is the throat that sticks out does not fit in the space provided on the axle for the bearing and retainer ring. On the non-abs axle there is 36mm from where the bearing buts up to where the snap ring is inserted in the slot. The bearing pictured measures 28mm including the lip and the retaining ring is another 13mm totaling 41mm. According to the auto parts store the non-abs axle came out of a 2002 tacoma. Which uses a bearing without the lip and measures 23mm+13mm for the retaining ring to get 36mm. So everything should be getting pressed together soon and I should get my truck back today thank god! Maybe this will help someone in the future if they are every faced with this issue.

 

Glad you got it figured out!
So...for future reference.What are the part numbers for abs and non abs bearings.Is the 90363-40068 one in the pic the right one or the wrong one?

Which seals?......90310-50006?

 

When I go back to pick it up I'll get all the part numbers for everything.

 

Sounds good!
Kind of confusing because Toyota parts catalog list the 90363-40068 bearing(the one in your pic) fits them all.
My pics below are from the Camelback toyota parts catalog(2001 tacoma prerunner) I gave you a link to, in a earlier post in this thread.
Looked up 2002 also and no change.
90363-40068 is #5

 

$49 90363-40020-77 Radial Ball Bearing

90363-40020-77

That is the part number used on my 99 8.4 axle and a 00 elocker axle. The 8.4 did not have abs and the elocker axle was setup for abs. Neither of them use a bearing with a thicker inner race like you pictured.

 

Thru 2000 takes

$49 90363-40020-77 Radial Ball Bearing

90363-40020-77, 23mm, no extra lip. Been there done that many times.
2001 and up takes 90363-40068, 23mm plus the lip
Only difference is the lip. Seals are the same.
An educated guess would be the earlier bearing would "work" in the later application but the later bearing would not work with the earlier bearing housing.

 

Is it possible to use a non-abs axle in an abs housing then?

 

The non-ABS axle does not have a machined area long enough to accommodate the ABS ring and the second retainer. It's just long enough for the bearing and one retainer. One could do away with the ABS system but there would still be no place for the inner retainer to sit so the inner seal would not be sealing against anything.

Marlin once made an adapter to relocate the seal from down in the axle tube (ABS) to the end of the tube (non ABS). Kind of a reducing bushing in plumbing speak. Others have fooled around trying to find a seal that would fit the larger diameter of the outer end of the ABS tube.

 

this looks like a non-prerunner diagram, hence the w/o Prerunner 2wd nomenclature? Unless they have more on there that's not visible in your snippet?

 

Here is all the information ive gathered about this issue.

Prerunner ABS axle (original)
bearing part# 9036340068 or 511031 from autoparts store.
outer seal# 9031354001
inner seal# 903105006

Non-preunner, non-ABS axle (not the orginal)
bearing part# 903634002077 or 511021 from autoparts store.
outter seal# 9031348001
inner seal# 903105006

The inner seals are the same, the outter seals are different. The only issue other than the difference in parts in running a non-ABS axle (of this particular style). would be the inner seal not making contact with the widened part of the shaft. however ive seen different threads where people are either A. machining what i would call a "reducer" to reduce the lenght of the throat on the axle so the seal will make contact with the widened part of the axle shaft. or B. buying an oil seal that fits the wider part of the throat directly which is 75mmx40mm. I think i may just go the route of the oil seal that fits in the throat. I dont know the dimensions on the reducer and a seal seems like it will be easier to remove if i every find the correst axle at a decent price. I do belive some non-ABS axles run the exact same parts so the only thing needed would be the new oil seal or reducer. It just so happened that in this case different parts were needed. thankfully i will have a parts list for the job if i ever have to do this again and the knowledge to do it tmyself.

 

It's for a 01 Pre Runner.Just used some cropped screenshots .
They list all the parts for an 01 "universal and rear axle"in the drawing rather then break it down for the many different combos.You have to read and interpret what you have.

Again, I gave the link in post #7

 

I Have an non abs axle housing, can i put an abs axle assembly in there with a non abs bearing and seal kit? You seem to know your stuff right now.
