I also just changed tires from worn out mud grips to street

This answer was rated:

I also just changed tires from worn out mud grips to street tires & had the front end aligned & all the fluids replaced. Since then there's been a high pitched whine at highway speeds most of the time but it seems to increase if I pull to one side. Like if I'm going straight and there's zero force on the wheel the whining stops. Then if I put a tiny force on the wheel one way or the other it starts up again... just finished a 1000 mile trip with nothing failing. Dunno if that was highly risky or NOT? Also don't know if the noise was there when I had the mud grips on since there was plenty of noise just from them...

Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner till early morning.

Normally a swerve associated noise is going to be caused by a wheel bearing starting to go bad. If you think it may be related to read design or a tire. Try to pinpoint which corner is worse then rotate the tires and see if it moves to another wheel. Normally a swerve to the left points to a RF wheel bearing with the issue for example.

I guess that means i've got bad bearings on both the left and right because when I pull to the right it makes noise & when I pull to the left it makes noise. What about the differential?
Customer: replied 10 months ago.
To check the bearings I can jack it up and rotate the wheel, if it makes noise then I found it?

The differential will not be affected by swerving. It would make a noise based on applying throttle or coasting around 40-60 mph. A wheel bearing that is not in horrible shape is going to require a stethoscope to listen to it while the wheel is spinning at least 15 mph. A good sound would be like your ear close to a ceiling fan. A bad noise would be like hearing a blender from about 20 ft away.

How do get a wheel moving at 15 mph while it's jacked up?

You would run it in 4wd and if its 2wd then use a drill with a hole saw in it to hold it up to the tread and spin the wheel.
