CV boot questions

My son has a 96 Accent and the outer BJ boot wasn't ripped but it is
thin enough in a few spots that it was just starting to allow the
grease to leak out slightly. Time for a new outer boot before any
contaminants get in there. Since this vehicle has everything press
fitted together at that end of the axle you need to pull the whole
axle out. No big deal. I picked up the new boot kit so it had the
boot, 2 boot bands, and a tube of grease. I already had new boot bands
to go on the damper and the TJ boot. All set to go now. Wait a minute,
since the TJ boot had to come off as well and the spider had to be
removed, I now have to replace the grease in that boot. According to
the service manual the inner boot uses ONE-LUBER MK grease and the
outer uses CENTOPLEX 278M/136K grease. What is the difference between
these greases (besides the fact the BJ grease is black and the TJ
grease is a yellowish colour)? I even asked at my local Hyundai
dealership and the mechanic there couldn't answer the question. Maybe
someone here can help "learn me sometink new"... lol. Thanks.

I couldn't tell you. Any more, the Hyundai kits come with two tubes
of the same grease, so I doubt the difference is great. If anyone
actually knows the answer to this, I'd like to know what it is.
