New grease

[bandit86]

Had my 180,000 mile 03 diesel ram in for ujoints and ball joints. While out, I flushed the front wheel bearings with diesel several times, then loaded the with chevron semy-liquid grease, and a few pumps of moly grease. Not supposed to mix greases, yeah I don't care, ,this little bit won't hurt. Also loaded all 5 front u joints with a caterpillar extreme 5% moly grease, maybe that helped.

First thing I noticed was that the truck rolled in the driveway. Never did that before. And several red lights in town it rolled back too, something it didn't do. I didn't have a chance to do an long trips to measure overal efficiency, but I think it's better. Some unit bearings you can't re-grease, but maybe can with a grease needle. I always had this thought that oil filled bearings would tire asker than grease filled ones. I'd like to do a better trial, but likely wont have time till spring.

Maybe you freed up the calipers. For bearings to change that much they'd have to be really messed up before.

I did run a rear hub in the Sport Coupe in oil for several years until the seal failed. It did spin nicely when jacked up in the air.

The hub spun much free-er once the liquid grease hit it. Mind you, this is on a 3/4-1 ton 4x4 front axle. Before it took several pounds of torque to spin it, then it was almost free. What I'm saying is, grease gets old, hardens, maybe some of you would do better with new grease
