If the differential is full you probably are correct. Those bearings are large and tough so in the early stages of failure they won't show up as loose or noisy when run on a lift with no vehicle weight on them. Being a fairly reliable part, likely you can get one that is good from any scrapyard for far less than a new one.

I replaced my tierod on the passenger front.there is still some play in the left to right there is also a humming sound at speeds 40+mph. it's coming from the hub bearing or ball joint.


Any wear or play in a bush or rod usually gives a 'knock' or causes vibration, not a humming noise.
If there's play in the steering wheel that may be due to a worn steering rack and pinion.

A worn ball joint can cause a 'crack' noise and depending on the wear, vibration that will be felt through the steering wheel. A worn ball joint can also cause the car to pull to one side.

A humming noise suggests it is either a brake rotor/pad, or a worn driveshaft or wheel bearing.

Changing front axle assembly or wheel hub or both? Either way, need torque specs for all bolts.


you've got a bad axle shaft in the front and possibly a bad bearing in the hub. 4/wheel drive makes the front axle actually work. Theys no real pressure on these shafts when in 2/wheel drive.

2003 GMC envoy humming


  • A humming noise that increases with acceleration is an indication of, more than likely, a wheel bearing (HUB) going out. Could need an alignment or could have a suddenly off balance tire as well. Any increase in humming/vibration when turning a corner? If so when turning which direction?

My car vibrates causing this loud hum while


Hi:
;You most likely have a wheel bearling or hub assembly that is bad. You should be able to narrow the hum down to one side or the other. Other possibilities are a noisy engine accessory, such as a bad bearing on a alternator, or power steering pump, but you should be able to make that noise show up, just by rev ving up the engine, so if it only shows up when the car is moving, check out your wheel bearings.

2004 Chrysler Crossfire 25,000 mls auto, road hum noise


MOST of the hums after a while come from the diff as the back axle does the driving and almost all its life runs the same way except when going in reverse ,is the rear diff meshing and worn on both the crownwheel and the pinion and the humming gets slightly louder the faster you go and almost goes when almost stopped and this can also be the slight vibration you get so get the diff oil drained and refilled and check if there is any metal in the oil when drained if so thats your problem But it will last for years like that..Let me know how you get on RON
