Rear right wheel leaking grease?

Alright...My TJ has been making a humming feel/sound when it reaches about 40 mph for about a week. It felt like the tread may have been uneven or my tire was out of balance just slightly. However over the weekend I noticed there is grease on the street on the inside of the rear right wheel. Climbed under it and this is what I found, see picture.

I'm not a mechanic besides the basic oil change, thermostat and a few other minor things, but I'm pretty sure that's not supposed to leak. Is this something I could take on myself or should I play it safe and take it to the mechanic. I haven't pulled anything apart yet.

I have the 97 TJ Full service manual, but haven't found this in there yet. I don't have a lot of time to fix it this week though...go figure I'm off next week and would all the time in the world...but don't think it would last before causing serious damage.

Any advise?

On the axle shaft there is an axle seal holding all your fluid in the diff. They are notorious for leaking. In the past I jack up that side of the vehicle to let all the fluid run to the other side. Pull the axle shaft, slop some RTV on the seal and shove it back in place. I always use Right Stuff by permatex so it sets up quick.

In order to replace the seal you have to press the bearing off the shaft and that is no fun when the RTV works just as well. There are only 4 bolts holding the shaft in the housing. You can see them in your picture. Pull the brake drum, unscrew 4 nuts, pull shaft. It is a simple deal.

Sounds simple enough. I presume I'll have to replace the lost differential fluid as well? Haven't drained that and refilled it yet anyways.

Could it do damage if drive on it for to long? I assume that's probably yes...

if you run out of fluid yes...pull the drain plug, if no fluid comes out then go to the auto store get some fluid and fill it until it comes out of the fill hole. Just keep it toped off until you get a chance to fix it and you will be fine. It will only take a couple minutes to pull the plug and top it off.

The only bad things is the diff fluid gets on your pads. If you lift just the passenger side of your axle all the fluid will go to the drivers side. You shouldn't lose much. But fill it up after you seal up the leak.

That is alot of fluid so I doubt it but it could be the wheel cylinder going out. Check your brake fluid for rear circuit and see if there's any in there. Either way, axle seal or wheel cylinder, easy fix.

as long as you keep it full till you get a chance to fix it, it will be fine.

Alright got it lifted and can see where the leak is. It's actually in this picture but didn't notice it till I got it jacked up and the tire off. There is a hole on the bottom of the brake shield. The other side has a rubber stopper on it...but the leaking side doesn't and that's where it's coming from. I haven't pulled anything else off yet...but does this sound like the brake fluid or still a leak in the axle seal?

Axle fluid stays inside the axle. The brakes are on the outside of the axle. You will see the fluid leak if you pull the brake drum. It is either on the bottom side of the axle seal or up top coming off the brake cylinder.

Alright...I found this picture on here: Jeep Rear Drum Brake Remove - Install and Adjust. This is the plug I'm referring to that is missing.

Now I'm trying to pull the break drum off...but I have a dumb question. What kind of tool do I need to remove the 4 bolts? They have a rounded bolt except for one side which is flat and I apparently don't have what I need to remove it.

The rubber plug is an inspection cover that allows access to the adjustment rod for the brake drums. It doesn't really matter that it isn't there. I'm specific so I would replace it. Regardless, you shouldn't have any grease or lube on the inside of that plug.

The bolts you see with the one sided jobber is the bolt. On the opposite side inside the brake drum is 4 nuts that need to be removed. See the 4 bolts in this picture?

Hit it with a rubber mallet a few times and catch it before it hits the ground. The drum with pop right off.

You have to release the emergency brake. Then pull on the drum. It will pull right off. Or.. BFH

Looking at your pic it doesn't look to me like gear lube. That really looks like brake fluid. It is not thick enough in the pic but I can be wrong.

Just in case you didn't know.... diff fluid becomes less viscous as it heats up.

Ok drum off...now how do I get to those 4 bolts? The access hole that should be there according to everything I've read isn't and I don't have enough room for any leverage behind the axle to remove the bolts.

Any suggestions?

The access hole is definitely there, you have to remove the axle shaft to see and get to it. What axle do you have, D35 or D44?

It's a D35...I'm referring to the access hole in the axle to get to the nuts behind it. Which you can see in my previous picture that it isn't there. Am I missing something? Is there something else I need to remove first to pull the axle and get to the seal?

The diagram below is out of the TJ Full Service Manual of the axle.

The axle shaft needs to come out. Remove the diff cover and after having supported the axle on jack stands, shove the axle shafts inward so you can remove the c-clip that holds them in. The c-clip is hidden and is only exposed/able to be removed after the axle shafts are pushed inward. Once the c-clip has been removed, the axle shafts can be slid right out. A magnetic tool may help retrieving the c-clip.

This task is growing. Think I'm going to put everything back together and take it to my mechanic tomorrow. I'll see if they'll let me watch them do it, so I know for next time. Thanks for the help guys!

removing the c clip is nothing. you just pull it out then you can slide the axle shaft out and get to the bolts. take the 4 bolts out put some rtv on the seal and throw it all back together. taking it to a mech wont be cheap, at least 200 in labor and they will want to replace the seal.

Ok so I'm going to try this again after the Cowboys are done putting up a pathetic game against the Skins.

So all I need to do is jack up the jeep place the axle on the jack stands, loosen the diff cover and drain the fluid, remove the tire, remove the brake drum, remove the diff cover, find the C Clip, push in on the axle and pull the c clip out. Then I can slide the axle out, undo the 4 bolts, get to the seal, add rtv, then put it all back to together and add diff fluid?

One question...I only have to pull the tire off on the side I'm working on...not both sides? Correct? Only reason I ask is Jerry B mentioned "shove the axle shafts inward so you can remove the c-clip"...shafts being plural...so just checking.

hehe. You need a factory service manual.

You have to remove the cross shaft in the case so the axle shaft will push in. You see that little bolt at the top of the case? Take that out so the cross shaft slides out. Then push the shaft in and the C clip will come out. Then pull the shaft out the housing.

Don't get frustrated. Keep up the good work. Turning your own wrenches is rewarding.
