well from what i gathered with a crush sleave you have to re-torq your pinoin brearing ever so often or it comes loose, mine was loose? and i have no clue why, i tightened it b4 it did any damage prolly somewhere around 300 ftlbs and it still came loose again and destroyed my pinion bearing.......ill be reading into it more when i go to setup my new gears

299k miles on mine; I've never retightened it... knowing the previous owner, I bet it was never done before either, lol

well, now I have something to get my hands dirty with this weekend

All I know is I lost the pinion bearing preload and it ended up trashing a set of gears. There are a number of ways the crush sleeve can get over crushed and that dramatically increases the chance of damage to the diff.

The crush sleeve is probably fine for stock use, but start wheeling hard (and in my case with dual cases) and it's a liability that you don't need to worry about.

To the OP - WOW that's gross. You got a lot of cleaning up to do! Those pix should be stickied as the example of why you need to extend your diff breathers and check the fluid periodically!

yoterr

haha yeah, its def a good idea to check your fluids prolly every time you do an oil change...the diff's are just one thing i never got to, im still pretty excited that i was able to drive and wheel the truck just fine with 4.10's i cant imagine what its gonna be like with 5.29's

so are the gears still good?are you buying a new set of gears?

haha, those gears look clean compared to mine...

yoterr

yeah the gears r fine, just the pinion bearings are toast, but their 4.10's and i want 5.29's cuz the acceleration still wasent there, and offroad even in 4lo i still had to ride the clutch a lil,

GOOD GOD 87 that looks like it just had straight mud in it, is that ur front axle?

peow130

mud is a pretty good lubricant lol...
my gears looked clean as a whistle when i pulled my diff.. your guys' are just nasty..

yoterr

lmao looks like ur truck was well taken care of too, mines kinda lackin in that department....im sure there was a time when this thing was a street queen (everything under the truck is painted yellow and white) but apparently that time has gone

updated with new pics

iamsuperbleeder

that still crazy how it rusted inside there like that... I mean even it water gets in there, there should still be enough oil coating everything and keep it from rusting...

yoterr

i dunno man its gonna get cleaned out a lil bit more b4 i go to put the gears in so...n the truck sat for about 6 months b4 i started driving it, so maybe thats why?
