Additional Notes

  • The PAZ 3237-05 rear differential carries 11 liters of fluid, which matches the capacity listed for the 3237-01, 3237-03, and 3237-09 variants, placing all configurations at the same fill volume.
  • The 3237-01, 3237-03, and 3237-09 variants share a single capacity figure of 11 liters under normal use conditions, with no interval data listed for those configurations.
  • On the 3237-05, a first-change interval of 3,000 km applies to the rear differential. A first-change interval is a break-in service designed to remove metal particles and contaminants generated during initial component wear.
  • Following the first-change service, the 3237-05 rear differential operates on a normal-use schedule with fluid checks at 15,000 km and full fluid changes at 90,000 km.
  • The 90,000 km change interval on the 3237-05 is notably long relative to the 3,000 km first-change interval, reflecting the difference between break-in servicing and steady-state maintenance once the differential has seated properly.
  • The 3237-05 entered the specification record from 2013, while the 3237-01, 3237-03, and 3237-09 are recorded from 2012, representing the earlier group within the 2012-2013 coverage window.
