If your Chevy Silverado 1500, GMC Sierra 1500, or a bunch of other GM trucks from the 1500 series (think Avalanche, Suburban, Tahoe, Yukon) with 2WD is making that grinding noise from the front wheel, you've probably got a bad wheel bearing.

This MOOG unit, part number 515054, is the fix.

It's a direct replacement, brand new in the box, and it comes with the bolts and grease included, so you don't have to run to the hardware store mid-job.

This is a full hub and bearing assembly for either the front left or right side.

It has the ABS sensor built-in (it's an integral sensor), so your anti-lock brakes will keep working right.

It's a 6-lug pattern (6x5.5 inches) with 3 flange bolts.

MOOG is a solid brand, known for good quality, and it comes with a 3-year warranty.
It's steel, has a polished finish with rust protection, so it should hold up.

This one part number replaces a ton of others: SP450301, BR930417, 15037207, WB15053, you name it.

So yeah, grab this if you want that humming noise to go away.
