GM Genuine Parts RW20-10 (12479031) Rear Wheel Bearing

It’s more expensive than others but AC Delco is the best and I don’t want to have to redo it.

Bought a pair of these for my 2005 GMC Canyon (4x4) and they fit perfect (aka REALLY tight). I personally watched several instructional videos and read several how-to guides on replacing these, having never done this before. It overall went really well, although installing them took some time and patience using a 3lb sledgehammer and the old bearing as a makeshift punch. Removing the old bearings was easy enough with a rented bearing puller. Were I to do this again I would absolutely get a bearing driver, a large socket, or a piece of PVC that would let me pound in the bearing easier. It was hard to get an even hit using the old bearing, but eventually I made it work. Another trick I heard about was putting the bearings in the freezer beforehand, as the cold will slightly shrink them making it easier to install. After install I used a small amount of gear oil to pre-lube the bearings. After a couple days of driving I think I notice a smoother ride. My old bearings were likely original, making them 13 years old with 132k miles on them.

The Bearing Worked Exactly As Expected and Appeared to be of Good Quality!!!

These bearings were the exact: ( KOYO - made in USA ) OEM bearings I pulled out of my 2013 Silverado rear axle today. ( 10 bolt ) Upon inspection both bearings identically matched, rolled fluidly smooth, had zero flaws, scars or marks. A solid quality product. I installed these today, along with OEM seals, fresh fluid “Mobil1 75-90 syn” Absolutely no issues on test drive, bearings seem to be doing perfect. In fact, I had a slight vibration issue at various speeds over 60 MPH, after I replaced them today @ 140k miles, I immediately noticed a huge drop in vibration with the fresh bearings in. No noises, just smooth sailing. I’m not paid for this review, I’m just a regular joe who likes to save money and make sure a quality job was performed on my personal vehicle, with quality parts used in the process. These fit the bill great !

Perfect fit for my 1997 C1500 2wd rear axle bearing

Recently discovered that both of my axle seals were leaking. Decided to replace the axle bearings while I was there … no issues with his part. These are Koyo bearings which are legit. Rear end is quieter now and it also eliminated a roaring noise I was getting from my rear end when coming to a stop in my 2005 Chevy Avalanche.

Good fit, but not the same brand bearings that came off the truck.
