Past couple weeks i've noticed a small amount of fluid running down the passenger rear tire which appears to be comming from around the studs. First I checked my brake fluid and that was good. I started taking her apart an believe its comming from the hole in the picture (not sure if this is possible for anything to come from here...) or the seal between the axle and tire/break assembly. Any ideas about this?

 

It can only be one of two things. Brake fluid from wheel cylinder or gear oil for bad axle seal

 

x2 on axle seal.

 

My vote is gear oil...

 

anybody have any preference on 4" suspension lifts

Hit up a search on this one. They are all over. Neither of mine are lifted...yet. I found this a bit ago, may help.

I know it's about tires but they discuss lifts as well.

Sounds like its gear oil....Anyone know what size the bolt is too drain and fill the rear diff. is? I don't have anything that big so gonna have to buy one.

thanks

 

definately gear oil and your inner axle seal is shot... hear tell they are a major PITA to replace... good luck with this one...

 

15/16 or 24mm... the same exact size... almost...

 

Thanks everyone for all the help

 

Better check the diff level soon to make sure you're not too low.

 

yeah thats the plan, tried to check it today but didn't have a large enough socket. Gonna park it till I get it checked.

 

an adjustable usually works for me....or vise grips...

 

Mine was on too tight for an adjustable so im going to buy a socket and use that, thanks though

 

where in the 7 hells did that come from?


and yeah, a 24mm for the drain and fill plug

you'll need a socket for the drain plug because of the ridge around it, but either a socket or a wrench will work for the check/fill plug

 

yes, make sure that level dont get too low... i was an extreme case (extremely lazy) but i paid for it the hard way...

x2 here i had to rebuild my rear diff too....check the gear oil!!!!!!!1111

 

yea im with the majority here, axle seal gone bad usually caused by the wheel bearing going bad also.

 

yeppers; I was going to suggest that bearing while you're in there as well; you have to have it removed with a press anyhow to get to the outter seal


BTW, here's how you can tell if the bearing is SHOT

use a 6point socket to, if you want to make sure its diff fluid. just smell it.
