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

Bought a pair of these for my 2005 GMC Canyon (4x4) and they fit perfectly (ie REALLY tight). I've personally watched a few tutorial videos and read a few guides on how to replace them, I've never done that. All in all it went very well although their installation required some time and patience using a three pound sledgehammer and an old bearing as a makeshift die. The removal of the old bearings was easily possible with a rented bearing puller. If I were to do it again, I would definitely use a bearing mandrel, a large sleeve, or a piece of PVC that would make it easier to drive the bearing in. It was difficult to get a consistent hit with the old bearing, but I managed it in the end. Another trick I've heard of is to put the bearings in the freezer beforehand as the cold will shrink them a bit which makes installation easier. After installation I prelubricated the bearings with a small amount of gear oil. After a few days of driving, I noticed that the ride was smoother. My old bearings were probably original, so they're 13 years old and have 132,000 miles on them.
