Additional Notes

  • The Jeep CJ-7 / CJ-8 (1985-1987) carries a front and rear differential capacity of 1.2 liters each, with a check interval of 7,500 km and a change interval of 60,000 km under normal use conditions.
  • The rear differential on the CJ-7 / CJ-8 equipped with a trailer towing package shares the same 1.2-liter capacity and 60,000 km change interval as the standard rear differential, with no deviation in service schedule under normal use.
  • Both the Wrangler 2.5 and 4.2 in the 1987-1993 range carry a 1.2-liter capacity for both front and rear differentials, with a check interval of 12,000 km or 6 months and a change interval of 48,000 km under normal use.
  • The Wrangler 2.5 (1987-1993) front and rear differential specifications are identical across normal and severe use conditions, with the same 1.2-liter capacity and 48,000 km change interval applying to both.
  • Moving into the 1994-1997 Wrangler 2.5, the front differential capacity increases to 1.7 liters, while the rear differential sits at 1.6 liters, reflecting a change from the 1.2-liter figure seen in earlier configurations.
  • The Wrangler 4.0 (1994-1997) front differential holds 1.7 liters and the rear holds 1.6 liters, matching the capacity figures of the Wrangler 2.5 from the same model years.
  • Under normal use, the Wrangler 2.5 and 4.0 (1994-1997) share a change interval of 48,000 km or 24 months for both front and rear differentials, adding a time-based threshold absent from the 1987-1993 specifications.
  • Under severe use conditions, the Wrangler 2.5 (1994-1997) front and rear differential change interval drops to 20,000 km, compared to the 48,000 km interval applied under normal use, representing a significant reduction tied directly to operating conditions.
