But as a general rule, when it comes to bushings and bearings a bit of prelube is always a plus. It might take a few minutes - sometimes even an hour of running to pull enough oil from the rear end up into that pump to make it prime. A bit of grease will wash out quickly when it does prime and is cheap insurance in the meantime. [Reply]   [No Email]

Is that what you had in mind? just a little grease to get by until priming? Chad [Reply]  [No Email]

I would not hesitate to squeeze a teaspoon full into, onto, around and beside the bearing and race. As long as it didn't interfere with assembly, why not? Lube is cheap compared to hard parts.

I'd see no problem lubing the seals and bearings, even if they will be splash or imersed lubed later. I pact pto beairng snad lube the selas and the entire assemble in wheel beairng grease when i R&R them... same with the ballnut and other bearings in a steering box. i don't see how it could hurt as long as it goes back together correctly..
