this should help Chevy GMC Front Wheel Bearing Hub Assembly 2008 Chevy Silverado 1500 4x4 Wheel Bearing Replacement

Sounds like a bearing issue. Either a bad bearing, not seated correctly or not properly installed

You need to replace the wheel bearing. I would bet it is the right side. When you turn to the right the load of the vehicle is transferred to the left. Less load on the right side and the noise goes away. It is a classic sign of a bad wheel bearing.

I can give you further instructions on how to make the repair. Just need to no if its 2 wheel drive or 4 wheel drive.

the bearing hub is a pre-assembled unit it has to be pressed together and the bearings have to be preloaded that is why you can only buy the hub assy. and it a whole lot easier to replace then the old 4X4 ft. wheel bearings.HAVE FUN

nowadays, mechanics can change an assembly and pay only $55 to $75 or up for the whole hub assembly complete with the abs wheel speed sensor.

The assembly comes with a new bearing. Otherwise, special knowledge and tools are required to press a new bearing on to the old hub, which probably is rusty.

So, it makes sense to change the whole hub assembly when the bearing goes bad, and many times get a lifetime warranty on the part..

Good luck on this one.

it is on the side of the transmission case near the rear

It sounds like you may have a wheel hub bearing going bad . Jack up front of truck and spin each tire and listen for any noise it should be quite and spinfree if you find it's bad you must replace the whole hub you can't just repair the bearing this is a common problem on the f250

That will be a Huge job. The whole front diff must come out of the car and the case will need to be taken apart to even gain acess to the carrier side bearings.
The hub bearing is where the wheel bolts up is that maybe what you are talking about?
Also the axle seal isn't that bad to do you need to remove the cv shaft then it's just a simple remove the seal and install the new one.
But all of these jobs will be big ones.

Sorry this is a very difficult job and you will need special tools,take my advice and take it to your local spanner man

Jack up the wheel that may have the bad wheel bearing and position your left or right hand at the top of the wheel and the other hand at the bottom of the wheel and rock from top to bottom if there is over 1 cm of play your wheel bearing needs to be replaced and if there is excesive play from left to right your rack ends need to be gresed if the have a grease nipple or replaced hope i was some help
