    Default front hubs? need info!

    what is the correct grease for the front hub bearings? I pulled off the plate to replace the lockouts and on the pass. side. it has what looked like rusty wheel bearing grease, gritty, and on the drivers side there was what would be no more than axle grease in it. what is supposed to be in it? Im hauling it to Co. and dont need any problems so as im there new wheel cyl's and all are in order along with bearings and seals. thanks in advance.

    I don't know that there's really any "incorrect" grease you could use. Any general wheel bearing grease ought to do you fine. I use Lucas Xtra Heavy Duty grease for mine.

    Not that any bearing in an M715 would be "high speed!" Heh, heh, heh....

    Tim, you can pull a 715 alot faster than it will drive. We hit some high speeds on the way to W.I.T.C. a couple years ago.

    Good point. So you would agree that Lucas X-tra Heavy Duty Grease would be a good choice for that, eh? But I posted that more for the chuckle than anything else!

    Dave, normal wheel bearing grease will work fine. The water proof boat trailer stuff isn't really needed if you sealed the lock out hubs on right.

    Don't try to run the CO speed limit on I-70 of 80 mph either. Besides sucking gas like crazy, 60-65 and new grease will keep your M715 happy.

    True, but waterproof grease for the hubs/wheel bearings is just a habit from my CJ driving. We have a lot of puddles and creeks to cross along mountain trails and it's just plain hard to keep the water sealed out. I appreciate the extra protection a waterproof grease offers.

    No doubt the water proof stuff is better. However, the lube order just calls for wheel bearing grease of the standard type. So, I just tried to pass on to Dave that the stuff he uses on all the vehicles he works on will be just fine on his ice cream truck.
