Wheel Bearing Gone Bad?

Hey everyone I have an '05 Sport V8 4 wheel drive 49K on the clock. I put 265/70/17 NTG's on it about 2 thousand miles ago.

I think I have a wheel bearing going bad. The vibration will start around 55 mph and doesn't go away the faster you go. It does seem to smooth out a bit around 85-90 but between 55 and 65-70 it's definitely there.

At highway speed (55-65) if you turn the steering wheel to the right it goes away until you straighten the wheel again. Turn the wheel to the left and the vibration and noise change but doesn't go away.

I am assuming it's the right front.

Anybody have any input or ideas? I'm going to jack up the front and see if I can move the tire. That should confirm the bearing is bad?

Links on replacement?

Thanks.

dont forget to check if a wheel weight fell off ,loose lug nuts, also check alingment in case that wasnt done when ya got the new tires.

Wheel bearings aren't a common problem on T4Rs?

I've been on this forum for over 4 years and have never seen a post about a wheel bearing problem on a 4th gen. I'm not saying it is impossible, just not likely.

It may also be the vibration problem that is inherent in many of the 4th gens. discussed at length in the following link.

If your 4runner is stock (except for slightly bigger tires) and does not have a wheel spacer, then wheel bearing bad under 50k miles is a rare thing indeed! I would have your tires re-balanced on a proper machine with the proper adaptor.

Sounds exactly what mine is doing.

Driving down a very smooth highway not hearing much until around 55-70 mph. Turn the wheel to the right and it goes away until you straighten the wheel. Turn the wheel to the left and it doesn't go away.

I jacked up the front end and tried moving the wheel side to side; up and down and neither of the front wheels moved.
 
Those symptoms are exactly the same our GX470 was exhibiting at 75K miles. It was definitely the front wheel bearing. I replaced it with one from NAPA and now it is smooth as silk again. You have to press out the old one and press in the new. I had a local machine shop do the presswork for $35.

The one that is bad is the one that gets quiet when the side load is increased on it. If it gets quiet turning right (Like mine did) then it is the Drivers side that is bad.

I replaced both of mine just in case. They are unit bearings.

The front wheels dont necessarily have to move side to side for the bearing to be bad

Look like I have a job ahead of me.

I guess the brand of bearing isn't important? Buy a pair of them and start tearing into it.

I'm pretty sure I can handle it. I've done U joints on the front of my Dodge. Although this is different still should be an alright job.
 
It's not a hard job. Just take your time. Look how far the stock bearing is pressed into the hub before removing it so you know how to press in the new one for depth. It takes a BIG press and a bearing puller or similar tool to put between the hub/bearing to press them apart. I'd have a shop do the press work if I were you.

Is this the correct bearing?
