Bearings cleaned? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was replacing a lug stud on the front end and managed to drop the greasy bearing assembly right into the dirt.

How can I clean it? Could I just use gasoline or should I use something different due to the proximity to the break drums?

NO. Don't use gasoline on anything unless you absolutely have to. I've seen some bad things happen, man. Bad things.

Get some Brake Cleaner from NAPA (or as I like to call it "Liquid Gold"). It's in a spray can. Put your bearing on a metal surface or on a shop towel that you don't care gets grubby, and spray away. It'll take the crud right out from between the rollers.

Once that's done shake it out, blast it with the air compressor, let it dry, and it's ready to repack.

cobalt is right, don't use gas! You can also get some varisole, hell I guess that is how you spell it. It works good too!

Working on farm tractors as a kid, I used to clean out tractor bearings with diesel fuel. It's a pretty good solvent -- about like kerosene.

yeah that's ok. Diesel and Kerosene are oily and have a pretty high flash point (temperature point in which exposed to heat or ignition will actually combust). Gasoline is pretty low (it doesn't take much). The only thing about diesel and kerosene is they sometimes can leave a residue. Brake cleaner leaves nothing. It evaporates pretty quick too.

I thought you are not supposed to use compressed air or similiar on bearings? It doesnt have to be a compressor but next to near. You should let it air dry. I may be wrong!

You are not suppose to spin them with air.

Thank-you for the confirmation. I didnt want to 2nd guess someone who's probably been working on these trucks longer then I've been alive which is 24 years.
