I got 100,000 Km on a motorcycle wheel bearings and 190,000Km on a 1958 Chevrolet suspension with no problems and no excess grease. Especially nice not to have to periodically clean the grease from the motorcycle brake drums.
Anyone else tried this?
That's really nice but motorcycles don't pull 6500 lbs of trailer plus 4000lbs of truck like the Taco does, all hanging on needle bearings around two spider stubs barely 3/4" dia.
If I'm towing like that, I'll make sure all the dirty grease is pushed out and do it frequently... so what if the shaft tunnel is coated with old grease...it just gives less area for rust to start!
I think his point is valid for things like ball joints and tie rod joints when they had zerks: filling them till the bellows burst was not a good idea and irked me no end when they did it during service.
