702_MJ Posted December 9, 2007 Posted December 9, 2007 I was cruisin the street last night and i noticed a kind of rubbing and grinding noise in the front of my truck. Took a look and did not see any sign of rubing or anything from what i could tell. Kept driving and it progressivly got worse and seemed to slow the truck down a little every time I heard it, like somthing is rubbing that really aint supposed too. I amd gonna check the front axle fluid level, carrier and gears inside if they are seizing or anything, check transfluid, and just work my way from there. Any other suggestions because I have no idea what is making this noise, its either internal or something i couldnt see?
CWLONGSHOT Posted December 9, 2007 Posted December 9, 2007 Noises can be damn near impossible to track down. More often than not you stumble on the cure... That being said, we need more information from you. 1) When did this happen? 1a) turning? 1b) Slowing down or speeding up? 1c) Going over a bump? 1d) Going over a bump while turning? You get the idea... One other thing, what the last thing you did or had done to the truck? CW
702_MJ Posted December 10, 2007 Author Posted December 10, 2007 Man it just happens when i drive. I think when i was muddin a week ago I fell into a water hole and had the water up to the bottom of the mirrors. So my guess is that water creeped its happy @$$ in there and now its screwing up a bearing like you guys said. But the noise just happens driving period. So I'm gonna take it apart today and just start process of elimination. Check the brakes, bearings, axle shafts, carrier, etc. until the problem is solved. Thanks for the ideas.
CWLONGSHOT Posted December 10, 2007 Posted December 10, 2007 You have at it there fella!! :cheers: Let us know what you find. CW
offroader461 Posted December 10, 2007 Posted December 10, 2007 Mine was started doing that one day and it kept getting worse...so i limped home and jacked it up and found out my Pass side unit bearing assembly bearing were bad...replaced both sides and it solved my problems
702_MJ Posted December 11, 2007 Author Posted December 11, 2007 Man sounds like a good deal so I'll do the same. Is there any grease that i can pack in there to kinda prevent this again, like marine grease or something?
offroader461 Posted December 11, 2007 Posted December 11, 2007 no the bearings have a rubber ring that seals them off and my ring was partially missing...
702_MJ Posted December 11, 2007 Author Posted December 11, 2007 Well any way I started taking the stuff off. Is it bad to have half eaten BB's fall out when you take the rotor off, thought that was a clear sign. Well now I don't have a socket big enough to get the adjusting knut off, any ideas, i don't need a special tool do I? Another thing would it be a good idea to change all the oil seals around the bearings?
offroader461 Posted December 11, 2007 Posted December 11, 2007 its a 36MM socket you can get from autozone...yea that pretty much means that the unit bearing or wheel bearing is toast...i would check the wheel bearings first then check the back of the unit bearing and see if its grinding...if so just replace it with a new one...can't be rebuilt..either a J/Y replacement or buy new
702_MJ Posted December 12, 2007 Author Posted December 12, 2007 Yeah I just called a friend and he said I just gotta replace the hub,so i gotta replace it on each side. Hopefuly i can find one at pepboys or checkers.
Pete M Posted December 12, 2007 Posted December 12, 2007 Be prepared for stickershock on those unit-bearing hubs. :(
702_MJ Posted December 12, 2007 Author Posted December 12, 2007 Yeah I went to auto zone last night to get that 36mm, checked the price of the hubs and they were outragious! $165 for expensive and $100 for oe spec ones. I was gonna go through quadratec and order some but I need these fixed by friday morning.
offroader461 Posted December 12, 2007 Posted December 12, 2007 yea they are not cheap in anyway...i just figured i needed it done so i spent the money...mine were a bit cheaper b/c i know the guy who got them for me :D
702_MJ Posted December 13, 2007 Author Posted December 13, 2007 yeah then i found out that mine were not tapered, they're ball bearing, my dad changed the axle when he did the engine swap. So no they becam 150 a piece so 300 total, man i am now broke. Oh any specific technique to get the nut with the cotter pin off mine is seized pretty good and it its kinda got me confused and i don't want to break any thing.
CWLONGSHOT Posted December 13, 2007 Posted December 13, 2007 Clamp the stub shaft in a good bench vice and remove nut with impact OR braker bar and LONG extention bar. Of coarse you need to remove cotter pin and guard first... CW
Oizarod115 Posted December 13, 2007 Posted December 13, 2007 Clamp the stub shaft in a good bench vice and remove nut with impact OR braker bar and LONG extention bar. Of coarse you need to remove cotter pin and guard first... CW should be able to bust it with a 30" breaker bar... i'm scrawny as hell and i popped mine loose, if its still on the truck leave the tire on the ground in park or gear whichever and try to get it loose best way is with an impact... why waste energy? 36mm socket bTW
702_MJ Posted December 13, 2007 Author Posted December 13, 2007 see thing is its still attached to the axle. But luckily my friend's family I'm staying with has an impact gun.
Oizarod115 Posted December 13, 2007 Posted December 13, 2007 see thing is its still attached to the axle. But luckily my friend's family I'm staying with has an impact gun. blast away my friend!
702_MJ Posted December 13, 2007 Author Posted December 13, 2007 well i blasted away, everything was just coming off effortlessly ..........until i got to the hub its self. man when they put them on there, THEY REALLY PUT THEM ON THERE! so I'm taking a quick break then I'm gonna go back out and try to get it off.
702_MJ Posted December 13, 2007 Author Posted December 13, 2007 ok well i got the hub off. one question is the axle supposed to just slide out of the housing really easy? Thats a shock to me, so i don't know.
offroader461 Posted December 13, 2007 Posted December 13, 2007 yea it supposed to do that...don't worry mine did the same thing and i called a good friend(also a jeeper) and he said its normal
702_MJ Posted December 13, 2007 Author Posted December 13, 2007 Yeah I was trippn out, but i called a a fellow comanche owner, and he said the same thing. His truck got into JPmagazine's May 2007 issue in jeep shots. They called it Hawaiian MJ if anyone wants to take a look at it. He was hella stoked when he found out.
702_MJ Posted December 14, 2007 Author Posted December 14, 2007 well its done, hopefully it solves my problems. Thanks to everyone for the help.
