Does that '02 SS rear contain the optional SLP Auburn LSD? I ask because the visible aluminum cover would suggest such (it looks like the AAM cover that came with this option, unless you just swapped the cover from the previous Firehawk rear which may have had that option). If so, a conventional 80w90 lube (plus 4 ounces of GM LSD additive) might provide for better operation than the synthetic lube show above (Auburns can be picky about lube type). But if the SS rear has the standard (for that year) Torsen LSD, then the synthetic 75w90 is just fine.
