Jeep Wrangler, TJ (USA / CAN)

Additional Notes

• All differential fluid change intervals across the Jeep Wrangler TJ 1997-2006 lineup are rated for severe use conditions, set at 12,000 miles for every engine variant and axle configuration listed.
• The front differential on the 2.5 and 4.0 engines covering 1997-2002 carries a fixed capacity of 1.2 liters, indicating a single specified fill volume with no range variation for those axle assemblies.
• Starting with the 2002-2006 model years, the front differential capacity on both the 2.4 and 4.0 engines shifts to a range of 1.2-1.9 liters, reflecting that more than one front axle assembly may be fitted depending on configuration.
• The front limited slip differential on the Wrangler 2.5 (1997-2002) carries a capacity range of 1.2-1.9 liters, whereas the standard front differential for the same engine is listed at a fixed 1.2 liters, pointing to a physical size difference between the two axle types.
• On the Wrangler 4.0 (1997-2002), both the standard and limited slip front differentials share the same fixed 1.2-liter capacity, meaning no volumetric distinction exists between those two front axle variants for that engine and period.
• Rear differential capacity across all three engines and both model year groups holds consistently at 1.7-1.9 liters, a range that applies equally to standard, limited slip, and trailer towing package configurations.
• The trailer towing package designation on rear differentials does not alter the stated capacity or the 12,000-mile severe-use change interval relative to non-towing rear axle entries for any engine variant.
• The limited slip designation on rear differentials likewise carries the same 1.7-1.9 liter capacity and 12,000-mile severe-use interval as the standard rear differential across all engine and year combinations listed.
