Review on ACDelco GM Original Equipment RW20-10 Rear Wheel Bearing: Precision Performance and Reliable Durability by Damon Murray

These bearings were exactly: (KOYO - Made in USA) OEM bearings that I pulled out of my 2013 Silverado rear axle today. (10 bolts) Upon inspection, both bearings were identical, rotated smoothly, and had no defects, scratches, or marks. Excellent quality product. I installed them today along with OEM gaskets and fresh Mobil 1 75-90 syn fluid. Absolutely no problems on a test drive, the bearings seem to work perfectly. In fact, I had a small problem with vibrations at different speeds. over 60mph, having replaced them at 140,000 miles today, I immediately noticed a huge drop in vibration with the new bearings. No noise, just a smooth ride. I'm not getting paid for this review, I'm just a regular Joe who likes to save money and make sure my personal car does a quality job with quality parts. These fit great!
