Theyll be there thursday. Got them for 100 each. Now I just have to take my other hub off then wait till thursday.

Instead of ordering from Rockauto.com who I order from on a regular basis, I would instead remove one of your unit bearing hubs and take it with you to your local auto parts store & make sure you get the right hub. Sitting them next to each other & comparing their height differences is the only way to know for sure if you're getting the right version.

Installing the wrong unit bearing hub will lock the wheel up.
Dang this is a good thing to know. I didn't know this and would have most likely ordered online...which would have meant wrong bearing because that is how my luck works.

LouieDelTorchio Alright well I'm going to start taking the hubs off today. Ill let you all know how it goes

Patrick H Murphy usually enters here for me. If I just replace one, the other one seems to fail shortly after. It's probably just my luck though.

Jerry Bransford Not precisely at the same time, no.
02-10-2013 05:58 PM
LouieDelTorchio Also, is it normal for both front bearings to go out at the same time?
02-10-2013 05:43 PM
LouieDelTorchio Alright sounds like a good idea. Thanks Jerry, youre always helpful

Jerry Bransford Need to see Rockauto's page that shows the Timken part number.
02-10-2013 05:08 PM
LouieDelTorchio Is this the correct one? Rockauto says it is but I just want to make sure. Sorry about all the questions.

Jerry Bransford The hub's retaining nut was torqued by the factory & then locked in place by a nut holder which is locked in place with a cotter key. In other words, the nut couldn't have loosened on its own where simply retightening it would be the correct fix. Unless someone has removed the nut and didn't re-tighten it back properly, and since you say the tires have been properly balanced, it sounds like your fix is pair of new unit bearing hubs.

He was just making a guess. He was saying that maybe it wasnt tight enough. Both front tires are wobbling and have play in them.

LouieDelTorchio I had the tires balanced twix e by rwo different places. My dad said something about being able to tighten the nut on the hun assembly. He doesnt know too much about jeeps but could that be the problem?

Jerry Bransford A speed-sensitive wobble invariably makes me immediately think bad tire balance, or at least imperfect tire balance. But a bad bearing is possible too. Our TJs use what is called a "unit bearing hub" which is non-serviceable, it is replaced as a unit which is a fairly simple job. Timken is a desirable brand of unit bearing hub. At the very least, I would first have the tires very carefully balanced by a good tech who knows he needs to take a little extra time on your tires to try to solve a problem.

By itself, a bad alignment will not cause a shimmy or vibration.

Horn5413 You have to replace the wheel hubs. You can't repair them.

Wheel Bearings?

Alright so I've had this bad wobble at 40-45 for a while now, and I've checked the steering components and such for some loose bolts but it all seemed good. Then, I noticed my rear trackbar was loose so i tightened it, but still the problem remained. So i was reading about bad wheel bearings, and they say the test is to wiggle your tire when in the air. Mine has some play in it, not a lot, but some. I then put my tire on my brother's TJ just to check and there was absolutely no play in it. Both sides of my front axle have play in it. I'm wondering if this is my problem? If it is, is there anyway i can fix it or do i have to buy new bearings? I've heard you have to buy the whole hub assembly. Also, I think my alignment is off, but would that cause a severe wobble?
