Rubi front axle noise

Alright, this one might call for Jerry and the like My Jeep started driving funny, steering wheel shimmy's real quick left to right while going straight. Alignment and tire balance were good, so I thought U-Joints. Put it in 4x4 to do something, somewhere (can't remember what ) and I heard some clicking from near both from wheels. Okay, definitely the U-Joints on the hubs, right? So a few weekends ago I did some brake work. I figured while the brakes were off, I would spin the hub a little and see if there were any obvious problems with the U-Joints. Normally you can't see em when they go bad, but sometimes you can catch a broken cap or something. Anyway, I start turning the hub, and the darn thing is making a grinding noise. Like, metal on metal grinding. Not sure where to go from here. It could be any number of things in the front axle. I am going to have access to a lift on Saturday, so any suggestions on what to check/how to check it would be awesome. This Rubicon is still under an extended factory warranty, so if I can prove it's not a non-warrantied part, I can just take it in and let them deal with it.

Do both sides make the noise when you spin the hub? Any chance its the rotor rubbing on the dust shield? Could be bad hub or hubs or something inside the housing. Take it in a see what they say.

If there's no rocks or debris caught between the rotars & dust shield, next thought would be see if the brakes are dragging as you rotate.

Probably a good chance though its the Hub Assembly (unit bearing).

Rotor isn't rubbing dust shield, nothing caught in between, brakes were off when I spun the hubs, and both sides make noise. I am going to venture a guess that jeep did away with hubs were you could just remove a cotter pin, 36mm nut and replace the wheel bearing? How much are unit bearings? Are they covered under extended warranties (I'm guessing not since wheel bearings are wear/tear)?

Yep, front hubs that use separately replaceable bearings are pretty rare now. Most have been replaced by a sealed non-greasable unit bearing that is easily replaced as a small subassembly. Unit bearings are inexpensive, I'd guess $120-130 at the most from the last time I looked since my front axle no longer uses unit bearings. Unit bearings only held onto the knuckles by three bolts so it's an easy swap once you get everthing else off.

I'd just take it in and tell them "I've got an extended warranty, fix this grinding noise". Who knows what it is, hopefully it's nothing more than a unit bearing and not something inside the differential.

Yea it's (1) assembly now, but still same method, remove (3) hub assembly bolts, remove cotter pin and 36mm Axle Nut.

Depending on your local autostore I would recommend getting the Timken Hub Assembly. Typically run about $100-$125 ea.

Here's a place on the net thats a little cheaper.
Auto Parts Fast at RockAuto
Timken part number HA597449 $78.79

If it was the unit bearing then you'd start loosing your braking occasionally. because it will start separating and that forces the caliper out as well. If it's making a grinding noise can you determine if its coming from the diff?

Of course if you have an extended warranty then just take that bad boy in if there's nothing you can see yourself. Because your next step is going to be cracking the diff and looking in there along with pulling the shafts out to see if one of them is rolled pretty bad.

I can't do much right now. The garage is full of motorcycles, lawn care products, scattered tools, and my sisters broken toy. Celica Heh. I should have checked the bearing by trying to move the wheel while it was in the air. Stupid me. I am trying to get ideas of things to look for when I get it on the lift Sat. You guys have been awesome. The shop I am using is a well known, ASE certified trans shop. Worst comes to worst, i'll tell the dealer they did brakes and took a gander at the 6spd bearing rattle the dealer can't fix, and they noticed the front end noise, did a little investigating etc (with a "receipt" of course).

I used to turn wrenches, have my certs etc. Just haven't done it in awhile. There's that whole "if you don't use it, you loose it" brain problem though :-). Honestly, I'm just trying to avoid the $90 diagnostic fee and high dealer prices if it's not a warranty problem. I wanna make sure it's either inside the axle, or covered etc. U-Joints I can take care of, don't need to be bent over. Unit bearings = parked jeep for a few paychecks. I'm almost hoping it IS the front axle... Than a tech makes some money, and I can afford to fix her :-D

Alright guys. I got my Jeep jacked up in the garage until I can get over to the shop. I deffinitely know the trans mount is bad. It started banging on my way home last night and its cut through pretty bad..How do I test the unit bearings? I tried shaking the wheel like wheel bearings, but got no where. If I spin the tire in the air, it sounds like someone sanding metal real slow. Its definitely coming from the hub area on both sides, and the rotor is not rubbing the dust shield/debris etc
