Wheel bearing going bad.

Hey all got a front vibraion starting at about 50 and up, this is constant and steady. I raised the front today and the drivers side tire rolled smooth the passenger was tight.

Do you think the bearing is bad?

I looked up bearing on the net and found 2 types one says its square driven and the other says its rectangle driven.

one is coarse threads and the other is fine threads (I can figure this one )


Thanks
Brian Felts

Make sure your brakes are not hanging up to cause the wheel to turn hard.

Sounds like the passenger side caliper is bad. If it is tight it will heat the rotor and warp it causing the vibration. Your first indication it is a caliper is the rotor will be a different color then the other one, probably blue.

Does it pull to the right when you apply the brakes?

If so, replace the caliper and your problrm should go away. I would suggest you replace them as a pair.

Is your vibration felt in the steering wheel? If it's rocking back and forth, it COULD be brakes/rotor issues. If vibration source is more difficult to pinpoint, jack the truck up until the tire is off the ground and grab the tire on each side firmly and try to rock the wheel on the axle. If the bearing is bad it should rock or clunk back and forth. If it doesn't, I'd look elsewhere. Good luck!

No pull or wabble out of the rotors. No excess brake dust, but at about 45 it starts to hum with a steady vibration. It started to only do it a 70 mph but has become worse over the last few days.


Thanks for the input
Brian
