Is there a difference in grease applications? After recent work on the inner part of one driveshaft, the mechanic packed it with a pinkish grease. Prior to this it had black grease (probably 2 yrs/10,000 miles old). I'm about to work on both shafts now. I have a can of hi-temp red lithium based wheel bearing grease available. (GC- LB) Are these interchangeable? Can they be mixed? Or should I clean out all the new stuff in the recently repaired axle which only has a few hundred miles on it and is uncontaminated? I will definitely clean out the 2 year old grease. The recently fixed axle just needs a little to top off.
Thanks
