loud clunking

[GoaT]

i was driving my truck last night. i went over a set of train tracks, not too agressive or anything. but  a loud clunking has started im my rear axel, as my truck rolls. like every one tire rotation.

i see the drive shaft kick a lil but not alot. and the clunking come and goes.

i have 5.29s and its welded in the rear

what could be the prob? i replaced the pinion seal not to long ago, maby that bolt came loose? im about to tear in down.i just needed some guidence.

[79coyotefrg]

was this track crossing  at a "crossing"  if not you probably crushed the crush sleeve

[GoaT]

crush sleeve? like i just drove over it like all the rest of the cars. i wasnt off roading

[Duffil]

pull the driveshaft and check the torque on the pinion nut.

[79coyotefrg]

pinion nut    then check all U joints

[GoaT]

keep brain storming for me. i cant work on it till an hour or so.

thanks guys.

but whats a crush sleeve?

[Duffil]

it slides on the pinion and crushes down, maintaining proper preload.  Sometimes this is replaced with a solid pinion spacer.  looks like a top hat here:

its the only weak link of a toy diff,   the only  good way to go is a solid spacer

haha, not relly the only weal link.  you might have busted a tooth off of one of the gears.

was a crush sleeve something i needed to change when i did the pinion seal?

[79coyotefrg]

well it needs to be done when the third is on the bench

[GoaT]

well it needs to be done when the third is on the bench

well i hope it was already...

well the pinion bolt only tighened about a 1/8 turn maby less. this sucks i really dont want to tear the 3rd out. i guess ill have to run a stock 3rd. its gonna be a turd to drive tho...

[GoaT]

weel my axle is in the air. the clunk is every one tire rotation. same spot every time. is it a tooth?

[GoaT]

remember this is my daly driver. i have no other car...

[olivedrab85]

Pull the drain plug if you broke a tooth you'll know.

[GoaT]

Pull the drain plug if you broke a tooth you'll know.

just by pulling the plug? how?

Shavings/metal

[rebelKrawler83]

if theres a crap load of metal shaving that come out then yeah you know a tooth is busted off. you said it was welded in the rear right???

[79coyotefrg]

you'll have a chunk come out

my guess from what you said,  broke ring gear


i have that complete 86 wide rear for sale $100

[79coyotefrg]

what gear ratio do you have??

[rebelKrawler83]

there we go that would solve the problem haha

[GoaT]

k a lil chunk of weld broke off.. jammed up on the inside of the ring gear. so it would clunk everytime the pinion gear passes over it..

[GoaT]

i have cleared it. spinns fine and gears look good...

but. do i take it to be re welded? od get rid of is and put a locker. haha if i can get the money to do it..

5.29s

[rebelKrawler83]

pretty sure it would make that noise happen, hopefully it didnt mess up any of the other teeth

[GoaT]

it was a small peice. no bigger then a ball bering. 3/16 by 3/16...

[rebelKrawler83]

but the rest of the gear teeth and stuff are ok?

[GoaT]

everything looks great.. just that lil piece of missing weld worries me

[79coyotefrg]

chances are good  it DID  mess a tooth up,  and if it broke loose  the next time you go around a corner in town it could explode

get that out of there and put a open or locker init


i would run a spool befor i welded one

[rebelKrawler83]

yeah i agree get rid of the welded one cuz if it explodes your screwed and yea id get a spool cuz there cheap so yeah
