Additional Notes

  • The Lexus GX 460 URJ150 front differential holds 1.4 liters, while the rear differential holds 2.7 liters, reflecting the larger housing and gear set typical of a rear unit on a body-on-frame SUV platform.
  • The rear differential capacity of 2.7 liters is nearly double the front, a difference that corresponds to the greater mechanical load the rear unit carries as the primary drive axle in rear-biased four-wheel-drive systems.
  • For the Canadian-market URJ150 covering 2009-2021, both front and rear differentials share a check interval of 16,000 km or 12 months under normal use conditions, with no separate severe-use interval listed for that market.
  • The USA-market URJ150 from 2009-2021 specifies a check interval of 15,000 miles or 18 months for both differentials under normal use, while under severe use the same 15,000-mile or 18-month interval becomes a fluid change rather than an inspection.
  • The distinction between a "check" and a "change" at the same 15,000-mile or 18-month interval for the USA-market GX 460 means severe operating conditions trigger a full fluid replacement at the same mileage point where normal conditions require only a level and condition inspection.
  • Capacity figures of 1.4 liters for the front and 2.7 liters for the rear remain identical across both the 2009-2021 and 2021- URJ150 configurations in both markets, indicating no change in differential hardware between those specification entries.
  • The Canadian-market interval of 16,000 km converts closely to the USA-market interval of 15,000 miles, placing both markets on a broadly equivalent distance-based service schedule despite the different unit systems used.
  • The 18-month time component of the USA-market interval is notably longer than the 12-month time component used in the Canadian market, meaning time-based service triggers differ between the two markets even when the distance intervals are roughly equivalent.
