My tires look like this /---\ Any ideas?
 
So I noticed that both of my front tires are leaning inward on the top, and I had a mechanic look at it. He jacked each side up and pushed on the tire and it wobbled back and forth (both tires did this). I believe he said it was a worn drive bearing? So he called Napa who said you have to buy the whole bearing and hub assembly for $130- So I called the dealer and they said the same thing for $160.

Has anyone heard of this? I might have mentioned the wrong thing but im pretty sure thats what he said.

I looked on quadratec and they sell tons of bearings for $20-50.

Please chime in if you know anything about this! I'd love to save $200

Sounds like you need a set of unit bearings. O'rallies has them for 120$ or so apiece. Its an easy enough job to replace them if you are comfortable in pulling the front axles.

Oh btw you need to get this fixed asap.

burton861 11-12-2012 05:47 PM

So this is what I need?
MOPAR 52060398AC - MOPAR® Hub and Bearing for 07-13 Jeep® Wrangler & Wrangler Unlimited JK - Quadratec

I can't just get something like this?

If im way off in my reasoning here its because this is over my head... Im just trying to learn. Also I will not be the one replacing these in case anyone is wondering

wwch99tj 11-12-2012 05:52 PM

You would need the top 1

Check www.rockauto.com
Might save you a few bucks

Lol you better hope you don't have to replace the pinion bearing anytime soon. That would cost you way more then what your problem seams to be now.

Different bearings. You need the top one. The bottom one goes in the differential.

jtbaker1911 11-12-2012 07:56 PM

you need two hub bearings. One for each side. These are sealed for life bearings. You have to replace the hub assembly.

Raziel 11-12-2012 08:57 PM

Let me see how much I could get them for you. I might be able to save you some money if you want? I'll post later.

Yea, I can't get it for much less than 130.00

Sure it's not your ball joints? You might want to have a seconed opinion

burton861 11-12-2012 09:51 PM

Raziel- How could you get them cheaper, and how much?

Ruby- I am not sure what it is so I am open for opinions. If you jack the car up and are looking at the tire like this- O -then you can push the top and bottom and it will move back and forth. This mechanic is not "out to get me" so a second opinion would only be for knowledge, if that is what you were referring to.

Ruby Tuesday 11-12-2012 09:59 PM

It just sounds more likely ball joints to me, if your wheel bearings were so wore out that you could see the tire sitting off camber the bearings would be gone and the tire wouldn't turn at all. However, wore out ball joints will do exactally what you discribe

Since his wheel is wobbling I don't think it would be the ball joints. I had to do the bearings in my CJ5 it sounds like Chrysler made it so you have to spend more money than you should on a cj you can completely take apart the hub to get to the bearings.

Ruby Tuesday 11-12-2012 10:08 PM

I have never been into the front axel on my JK, I base my opinion on experience with solid axel Ford and Chevys. With that said I could be wrong

burton861 11-12-2012 10:12 PM

Sooo.... Ball joint or new bearing hub assembly? Who thinks what?

My bad I had an mind fart right their I was thinking of tie rod ends, it could definitely be ball joints. Also what kind of milage does it have because bearings should last a while if they are seated and lubed up correctly.

You would think so, but I have seen it happen a lot on vehicles with sealed bearings.

burton861 11-13-2012 06:15 AM

its got 32,000 miles on it. With 35 inch tires for all of those miles and it does go off road

Silverton34 11-13-2012 06:44 AM

I would think ball joints too. If the unit bearings were bad enough to let the tire visibly lean then they are worn completely through the needles and there would be significant noise. The balljoints would be pretty silent.

3JKs1H1 11-13-2012 08:38 AM

Both the unit bearing and balljoints start wearing the first day you drive the jeep. To see which ones need replacing (or both) jack up that side of the axle with wheel still on the jeep. To check the ball joints, slip a 2x4 under the tire and lift up, also leverage the tire back. You can also both pull and push the bottom and top. Have another person look at the ball joints for slop. If they are moving alot, have them replaced with the unit bearing.

The unit bearing will have it's own slop, up/down and side to side.

Cheaper to have them replaced at the same time that taking it apart twice.

Actually not a bad DIY project.

kik 11-13-2012 09:32 AM

Not only Jeeps. Any vehicle that I've seen with the wheels as you descibed needed ball joints.

With tires that big and taking it off road it's entirely possible that you have bent the axle a little. The D30 doesn't hold up in the long run to even stock tires when you take it off road a lot. The tubes can deflect and the ears at the ends of the axle can bend as well. Both will cause the /------\ problem with the tires.

The wheels wobbling back and forth a little also means that the unit bearings are wearing out. 35" tires off road will do that too. But new unit bearings alone might not get you back to looking like this: |------|

You really should put new unit bearings in, no question. But if you're still tilted you need to start making a plan to replace the front axle. Investing in a Dana 44 from someone like Dynatrac will, in the long run, save you money over swapping in even a Rubcon Dana 44. The Rubicon D44 is really a D44/D30 hybrid that has a lot of the weaknesses of the D30. An aftermarket D44 will be a lot stronger and will take the abuse of off roading a lot better than any factory axle.

Ruby Tuesday 11-13-2012 01:15 PM

I'm sticking to my ball joint opinion, unless you do some serious off roading or beat the crap out of your jeep your axels should hold up fine, keep in mind some people say a black eye is domestic abuse and others say its love. And I have no idea how you treat your jeep. If I were you I would have at least two mechanics look at it.
Keep us updated

Cons_Table 11-13-2012 01:36 PM

I am not a JK guy...but I am gonna second the ball joint thought. I say this for a couple reasons:

1: My TJ has 125k on it...about 45k of those miles were mine. I have not replaced the unit bearings yet, and I highly doubt someone else did. Mine are making a gritty noise, so they do need replaced, but my camber isn't jacked up because of it. 32k seems like an early life for wheel bearings unless you spend all your time playing in the mud.

2: When I replaced ball joints on my jeep, I had some slop and some bad tire wear patterns. They did not cause my my camber to be messed up though. However, when buying ball joints, they had the factory style (cannot adjust camber) or they had another style where you could adjust camber...theoretically, I would think that an extrememly bad ball joint would cause messed up camber.

It is very common that bad ball joints result in being able to move the wheel back and forth. 3JKs made a good comment on how to check this.

@derf...My understanding is that a TJ Rubicon D44 front axle is basically a Dana 30...except for the differential and the inner axle shafts. A JK Rubi 44 is much closer to being a true Dana 44. I also don't believe that you will go about bending and screwing up factory housings unless you are jumpin and bouncing the jeep. Granted I do not know how the OP drives offroad, I am not convinced that bent axles is a normal occurence.

derf 11-13-2012 03:43 PM

Of course, my input is only speculation. It's impossible to tell by just what is said on a message board. I only suggest a bent axle as a possibility. There are as many truss/reinforcement kits for the front axle on the JK as there are for the TJ. Probably for a reason. The best course of action for the OP would be to give it a thorough inspection and alignment to see what is actually wrong with the Jeep.

burton861 11-15-2012 04:45 PM

So I got new unit bearings on each side and my tires are straight as an arrow!
