Took my 14 Nissan Xterra into a driveline shop today to have my rear diff inspected for a whine on the power side at 60mph. Everything checked out according to them, backlash, etc. Possibly the gearset is worn but the cost is prohibitive to rebuild. ( $2500. 00) vs finding one at a junkyard.
The mechanic said he used 80W90 (GL4) vs 75w90 in my rear diff. I'm planning on dumping it out soon. Any harm in using 80w90 vs 75w90?
