Alright everyone my rear end messed up in my truck last night so today i took it apart and found this....i dont really know what went wrong because everything is trashed...my spider gears are just rolling around and my pinion gears are chewed off and they are all broken i was looking at doing 5.29 or 5.71 with a lockrite locker from low range off road....any opinions on this oh and i have a 1990 toyota pickup with 37-14.50 and

 

Well not knowing what went wrong, is a problem in itself. If you don't know how they got messed up how can you prevent this from happening again? Were they making noise and you kept driving? Did you have any inkling something was wrong? When they failed, how DID you know? What kind of wheeling do you do? Mudd, fast, Rock, slow? Do you have a rear diff breather extender? Did water get into your diff? How often do you change your diff oil, or look inside of there?

See this will help many of us give input as to what kind of money you should put back into your diff.

I'm not making fun, just need some more info here as to how you think your rear diff failed, and where it failed.

 

Oh and some punctuation in your post would be nice.

 

Mainly mudding and some trails. Change fluid about 6 months ago.i have a breather extended to the top of my bed. I have been hearing some poping noise but never knew what it was im guessing this was it haha.

P.s. Got my periods just for you mr lysmachia didnt know you was a grammer teacher

 

Oh and i was driving on the road when it broke.

 

fix'd.

 

OH haha thanks peow and sorry lysmachia!!!

 

Um YEAH! Here's the deal. If you do the same thing again, or install new gears without knowing what happened, the same thing may just happen again costing you loads of money...

I assumed as much. What speed? Though this may not matter as much as the above. The mudding part can lead to a broken diff a lot faster than rock crawling.

It just helps those of us who are going to take the time to help you, to read your question is all.

Good one. Yes Yotamonsta.. I am a Lady.

 

yea im trying to get more into trail and crawling....probally doing 20 when it broke. it felt like it locked and the snaped loose. sorry about the pics i took them with my i phone so not that great. everything in there is trash now. All gears are chewed up and missing teeth. And thank you for your help

 

Naughty Naughty, lets not be mocking the staff

Looks to me like your pinion bearing wore out to the point where it allowed your pinion gear to touch the differential carrier. Then things started breaking.

If the case isn't chowdered, you can just have a new gear and bearing set stuffed back in there. If it is, you will have to get a new diff and have it rebuilt/regeared to your specs.

 

Well i was looking at doing sas soon and i found a guy selling both axle from and 82 with 5.29 gears and lockrite locker with 400 miles on them for 800$ ...imma be spending almost that much on the rear axle to rebuild it? Think it a good deal or no, he will let me take it apart also to look inside?

 

id say look at em and say ill take em for 700$$$

 

Pinion bearing wore out and the crush sleeved crushed and carved a nice set of grooves in your carrier. Done.

Rebuild your diff with a solid pinion spacer and get someone to build your diff who has a clue what they are doing.

 

x2 dc!

where did the center pin go? that would explain the floppy spider gears lol.

 

I'm with DC... had the same thing happen to my 93....although....I rebuilt that one from 3 different used diffs, and just eyeballed it back together.....still got 60k before it genaded tho....

 

Im going to tear it apart today and see what else i can find....i will take alot of pics but this thing will only let me ypload 3 pics? and the guy is willing to meet me half way from alabama and im in texas so it will be five hour driving one way for both of us!!! i told him if he would meet me and let me tear them down if all was good id give him 800$ my dad wil go with me cause he knows a littl more of what to look for and a lil more about it then me.... Thanks for the help guys!!!

 

x3 - same thing happened to me and AxleIke due to the torque of dual cases. I would imagine full throttle mud assaults with big tires are what spell doom for yours. Be sure to use a solid spacer and really crank up the carrier bearing preload. See www.gearinstalls.com for more info on how to build a diff to take abusive use.

I would also recommend you check your housing very carefully and make sure it isn't bent.

You are a prime candidate for the Front Range Offroad full-float conversion kit.

 

The 82 rear axle is 3" narrower than your current axle. I would just take the 3rd out and put it in your current housing.

 

Oh i actually did not know that.. So should i use the same axle shaftes and everything??

 

pinion barring failure for sure, it had to have been doing that for a while to wear through your carrier enough to break it. your fault for not keeping up on your stuff..

+1 on just swapping the third..
