so, while greasing the wheel bearings on my boat trailer with the bearing buddy, it made me wonder if such a thing could also be done on my solid front end toyota. i was thinking, take the hub off, and drill a hole between the races, insert grease nipple and re install. let me hear your opinions, good idea? bad idea?

FWIW: im talking about the hub.... which houses the wheel bearings..... NOT the locking hub.

in theory it sounds good, my major concern would be blowing out the seals. You have to have some place for the air to vent. I know they are not 100% sealed, but a grease gun delivers alot of pressure.

lol true........ but your assuming the seals in there are good LOL

Grease guns put out a lot of pressure, our machinist makes little jacks to move equipment with grease guns, something like 12 to 14,000 psi. :eek:

In applications similar to what you are thinking about we generally have labrynth seals so the grease,air and pressure have a place to escape.(too much grease causes heat) Good idea in theory, thought about it myself a lot. [cheers]

good point on the heat joe, didnt think of it. if you have that much grease inside a bearing housing, its gonna get hot, and potentialy do more damage than good.

I run synthetic grease in my wheel bearings and birfs, they seem to run cooler and displace water..:D
