Jeep Wrangler, TJ (EU)

Additional Notes

• The Jeep Wrangler TJ (EU) front differential capacity for the 2.5 and 4.0 engines covering 1997-2002 is listed as a fixed 1.2 liters, while the 2.4 and 4.0 engines from 2002-2007 carry a wider front differential capacity range of 1.2-1.9 liters, indicating that multiple axle variants were fitted across the later production period.
• A capacity expressed as a range, such as 1.2-1.9 liters, typically reflects the presence of more than one axle assembly type within a given configuration, where the lower value applies to one unit and the upper value to another.
• Rear differential capacity across all three engine variants and both production periods holds consistently at 1.7-1.9 liters, regardless of whether the axle is a standard open unit, a limited slip unit, or one paired with the trailer towing package.
• The front differential on the 1997-2002 2.5 and 4.0 engines holds a fixed 1.2 liters, which sits at the lower bound of the 1.2-1.9 liter range seen on the 2002-2007 front axle specifications, suggesting the earlier period used a single axle type at the front.
• Limited slip differentials on the Wrangler TJ (EU) share identical capacity figures with their open-differential counterparts in every listed configuration, meaning the addition of a limited slip mechanism does not alter the fluid volume specification for either the front or rear axle.
• Rear differentials equipped as part of a trailer towing package carry the same 1.7-1.9 liter capacity as non-towing-package rear units across all engine variants, with the distinction between configurations appearing in the application note rather than in any change to fluid volume.
• All capacity values across the full 1997-2007 span are associated with normal use conditions, meaning none of the listed differential positions carry a separate severe-use interval or capacity figure in the specifications.
