How to Grease Car Wheel Bearings

Video Transcript

"DOUG JENKINS: Hi. I'm Doug. I work with 20 great guys in St. Louis at Doug Jenkins Custom Hot Rods and we're going to do some work for you today on Expert Village. The next step in installing the front brake rotors, Mark is taking the new bearings and he's got this--a nice tool he got from the Snap-on guy that greases the bearing, it pushes the grease up through the center of the bearing. So he sticks it in there. He then takes a little bit off from the tool and wipes it around the outside. It doesn't take a ton of grease. It just has to have grease on them. All of the entire bearing and that's absolutely perfect just like that. The smaller bearing is the outer. The large bearing is the inner. You never mix and match bearings. You would never take an inner--they always come as a matched pair. You don't want to take the inner from inner bearing from one and put it on the other after they've been used. When they're new, you can swap them around, but not when they're used. A bearing wears into its race as it goes along. Mark's going to put a little bit of grease on the seal so that it seals better and preserves the seal; it doesn't melt when it goes on the spindle. So now Mark is installing the seal, getting everything clean, so it goes together nicely, it doesn't splatter grease all over the place. Again, installing the seal's a little bit tricky. You want to hit it as evenly as you can; have it go down at the same rate all around the perimeter so that you don't damage the seal."
