Wheel Bearings
« on: December 12, 2017, 10:04:48 AM »
I have a few questions.
I am really annoyed with myself I just recently replaced the Axle and all associated parts except the wheel bearings that had 30,000 miles on them. Now I think the bearings are going bad. Drove the jeep yesterday and a really god awful sound was coming from the front end. I completely over looked this. :swear_mad: 

1. How often are you guys going through wheel bearings?   

2. What brand are you guys typically using?

3. Would a bad wheel bearing cause a vibration at higher speeds? There is a fine vibration above 50 MPH it gets worse as you get faster. Sounds like I have a Sub in the Jeep that is just playing a constant bass signal.

Thank you,
Ryean

1. It varies, but with 30k with wheeling (especially deep water/mud)  and larger tires and reduced backspacing, they could very well be bad.

2. Stay away from the economy brands like Duralast, go with Timken.

3. Yes, especially if the noise is proportional to speed, probably wheel bearings.

I'm 10 min away, so let me know if you need a hand or tools.

Thank you Rey! That is what I thought. I am just annoyed with myself for not replacing the bearings when I had it apart. Good practice right! I will let you know if I need a hand I appreciate the offer!

Thank you,

as much as it sucks, we have all been there.

Better in your driveway than the trail.

I preferred the brake on the trail tho, more hands to help that way.... JK

Jack up one wheel at a time and rock the tire top to bottom.  See if there is any play.  If there is, the bearings are bad.  Do you have individual bearings or a unit bearing?  Usually, if a wheel bearing is whining you can get the noise to change as you move the steering wheel back and forth loading and unloading the bearing.  Find a big open parking lot and dive around in figure 8's and see if you can hear it change.

With that said, I have had bearings really loose and never felt it, or heard it on the road.

All the National bearings I have put in recently are made in China these days.

I called and looked everywhere for the Timken brand no one seems to carry them. I did not try Rock auto.
I did lift the front end this evening to see if there was any play in the wheel to my surprise it was tight. I also did the figure eight, the sound was there when I was turning to the driver side and going straight. I turned hard passenger and now it is gone, really weird. I was able to get it to do it again when I was in reverse turning passenger.

Turning hard passenger will put more load on the drivers side tire and take the load off the passenger side causing the noise to stop.

I've got a CAP auto parts store nearby that always has Timkin unit hubs in stock. Do what Terry said to see how much play there is, if it's bad replace it sooner than later, the result of one failing on Rt 2 West is not pretty...

I lifted the front last night there was no play at all. I was surprised...

Did you happen to spin the wheel while it was up to see if you could replicate the grinding noise?

Hubs are weird, they usually just whine as they go bad. By the time they get to "god awful" level in my experience that means they've got about a mile left before the wheel falls off.  :rotflmao:

Might as well change them anyways if you've got the parts, keep the old ones to make loaded spare shafts (nice not to have to mess with that 175 ft lb axle nut on the trail) but I wouldn't be shocked if the vibration and noise is still there and is coming from the driveshaft, U-joints, somewhere else.

I did spin the tires to see if I could pinpoint exactly where the noise is coming from. Unfortunately I could not reproduce the noise. I just contributed it to not having a load on the wheels.
I do agree with you on getting rid of the vibration. I do not think this has anything to do with the wheel bearings (I am Hoping). I did have the front driveshaft rebuilt do to it being bent. I honestly think its either in the gear set up, or its something with the transfer case. The vibration is more harmonic you really don't feel it, but its visual in my rear view mirror and it sounds like I have a stereo system with a constant bass note being played.

I would think the unit bearing may not be as bad to have play but after sitting the bearings had time to pit and are damaged . I agree on while lifted they wouldnt make noise as the werent supporting any weight .   That vibration thing sounds bad . Id pull the DS and take her for a spin. See if they did their job. Usually a bent shaft get re-tubed not straightened. Then there is always did the balance it after they were done. Gotta start some where , its free and easy.     FjR68
