wheel bearing mobil 1

[ron55]

anybody using mobile 1 in their front wheel bearings? I am and have change it 4or5 times because of the color. well there is no leaks, no water and it turns tan almost immediately. I have a two jeeps and mobil 1 in every gear/differential and while checking the front end I found the oil tan. I am thinking about going back to dino oil.
by the way I just read a a 4 stroke outboard oil test which included mobil 1 and the cheap old regular pennzoil won out over some expensive brands such as yamaha, suzuki, quicksilver, mobile 1 amd a couple more that I caint remember. penzoil had more of the additives to prevent corrosion, wear, shear and some other things. test piece of metal was oiled and soaked in salt water. I have never run penzoil but I am considering it.

Ron, This is just a suggestion to rule out a condition. Remove the tire and disassemble the hub. Remove the caliper, etc. Remove the spindle nut and pop out the outer bearing. Continue the disassembly and remove the rotor.

Remove the inner bearing. Get some brake clean and completely clean out the hub and spindle. Check the bearings for any abnormality. You may want to install new inner seals, they might leak. Put everything back together - you know how to load and set the bearing adjustment. Restore the cotter pin. Install the hub and gasket if it looks OK.

Restore the OE (stock) 90W GL-5 gear oil Pn#1052227. Take 2 aspirins and call me in a week or so and I bet the fluid color will stabilize.

One has to rule out the interactivity between fluids as this might have caused a reaction between 2 or more of the fluids used regardless of the fact that the fluids are labeled compatible. I would expect that the lubricity is there and this would be the method I would use to rule out the color issue.
