Recently my truck developed a nice growl/grind noise in the front right.

Today I replaced the wheel bearing and hub assembly. Slightly less vibration, but no other change. I also replaced the gear fluid and it was clean and had not water in it or metal shavings/dust.

The grind/growl is especially pronounced while coasting at lower speeds (15-20mph). Turning the wheel side to side doesn't seem to affect it one way or the other, applying the brakes sometimes makes it vibrate more at low speeds.

I'm kind of at a loss for what to do next.

Any ideas, hive mind?

 

Did you replace both sides, or just the right?

 

I just replaced one side the right. People are telling me to check the u joints on the axles.

 

Get under there, ideally with the axle jacked up (front wheels off) and spin the wheel by hand, watching for play in the u joint. You can also grab the yoke/ujoint part of the axle at the way end (even with wheels on ground) and push back and forth/up and down to check for play. If they're real bad, you'll see them "clunk" when spinning the wheel.

I don't see them making a grinding/howling noise, however...

 

If you want to take the time, you can read through this data.

There are 6 steps to the thing, as can be seen at the bottom of the page.

Also, there's a link to TSB 03-05-99 that you may want to look at.

Found out what it was. It turned out to be the two front tires they have signs of cupping I switched out the front to rear and its gone. You can hear/feel a slight vibration from the rear but it isn't too bad anymore.
