Wheel bearing grease

I just finished performing a little routine maintenance on the TT wheel bearings. After removing the hub cap, I used a small flat head screw driver to remove the rubber cover from the center of the hub. That revealed the grease point. Using a hand pump grease gun, I filled the hub until I could see the grease coming out from the center. I then replaced the cover and hub cap and went to the next tire. Now, all I have to do is put some grease on the hitch ball and I'm ready.

I was just about to do the same. How much of a tube does each one take?
Thanks.

When I grease the wheels of my various trailers (re: TT, Utility Trailers, boat trailer), I always "pull their hubs". Always. When hubs are off, I inspect their brake pad thickness (replace pads if needed), I take fine grit sand paper and rub the inner brake drums (to remove rust on the brake pad and contact points), and I inspect their inner brake wires / magnet thickness as well. If a trailer sits for 4+ weeks, it will get natural rust on the hub's surface (where its brake pads touch). Thus, use fine grit sand paper or steel wool to rub it off - going "with the grain" of its movement. Every other year, I replace the hub' rear seals as well. Thus, doing a proper brake and wheel bearing greasing.

By only adding grease, the condition of the brakes are being ignored. And, older age seals are left in place. IMO, the proper way to grease a wheel hub is to remove each hub (its older grease is 100% removed), new grease is installed and maintenance is also done on its brakes. For grease type, I like to use boat trailer grease. re: Marine wheel bearing grease is much better then normal "low grade" wheel bearing grease.

Hope this helps in future brake job greasings....

Whoa buddy... You may have over packed those bearings...One or two pumps each wheel is all you need... my buddy did the same thing you did .. and filled the brake drums with grease...when be blew out the seals...

(This would be nice to have a DIY video on how to do this! In a quickie search, I couldn't find one on Youtube, but I thought I saw one there once !)

I agree totally. Grease in the brakes will only cost you more money.

I can speak from experience. I kept pumping until the grease came back out. We went camping in the Sierras and on the return trip I noticed the TV brakes were getting hot ( I carry a temp gun) so I took my time getting home. Inspected the drums and two had grease all over the shoes.

I now give each zerk two pumps.

Those YouTube vids are great. Thanks.

Not to point fingers at anyone, but it seems that the wheel bearing thing gets overdone. Pull the trailer a couple of thousand miles or kms, and - oh! time to grease the wheel bearings again! If there is no sign of grease leaking out, or the bearings turn nice and easy, leave them alone.

I'm not saying to never tend to such matters. We think nothing of driving down the freeway at full tilt with our vehicles for thousands and thousands of miles, and seldom, if ever, check the wheel bearings. Just take it a bit easy with the grease gun.
