  • Capacity 2,65 liter (+ differential lock)
  • LX 450 (USA) (1996-1997)
  • Rear
  • Use: Normal
  • Capacity 3,25 liter

Additional Notes

  • The Lexus LX 450 front differential holds 2.8 liters under standard configuration, while the variant equipped with a differential lock carries a reduced capacity of 2.65 liters, reflecting the additional mechanical components housed within the differential casing that displace fluid volume.
  • The rear differential of the LX 450 (USA) for 1996-1997 has a notably larger capacity of 3.25 liters compared to either front differential figure, consistent with the rear unit bearing greater torque loads in a body-on-frame four-wheel-drive platform.
  • Both front and rear differential fluid specifications for the 1996-1997 LX 450 (USA) are listed under normal use conditions, meaning the intervals and capacities apply to standard driving rather than severe-duty cycles such as frequent towing, off-road operation, or extreme temperature exposure.
  • The 0.15-liter difference between the standard front differential capacity and the differential lock variant indicates that the locking mechanism occupies a measurable portion of the internal fluid space, a detail relevant to ensuring neither overfilling nor underfilling during a service fill.
