Lexus LX, J310 (USA / CAN)

Additional Notes

• The front differential on the Lexus LX 600 AWD holds 1.16 liters, a relatively modest capacity that reflects the compact housing typical of front differentials in full-size AWD platforms.
• The rear differential capacity of 5.45 liters stands notably higher than the front, which is consistent with the greater mechanical load carried by the rear axle in a rear-biased AWD layout.
• The limited slip rear differential variant holds 5.25 liters, a slight reduction compared to the standard rear differential's 5.45 liters, likely due to internal components associated with the limited slip mechanism occupying a portion of the housing volume.
• Under normal use conditions in the Canadian market, the rear differential fluid change interval is set at 96,000 km or 72 months, whichever comes first, giving a six-year maximum service life between fluid changes.
• The Canadian-market front differential carries only a check interval of 16,000 km or 12 months, with no change interval listed in the specifications, distinguishing it from the rear differential entries which include both check and change intervals.
• Under severe use conditions in the US market, both the standard and limited slip rear differentials share the same change interval of 15,000 miles or 18 months, despite their differing fluid capacities.
• The severe-use interval for the US market front differential is also 15,000 miles or 18 months, aligning with the rear differential intervals under the same use condition, and no check-only interval is listed for any US-market entry.
• The Canadian-market check interval of 16,000 km or 12 months applies uniformly across the front differential, standard rear differential, and limited slip rear differential under normal use conditions.
