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.
