One problem related to axle assembly has been reported for the 2000 Lexus RX300. The most recently reported issues are listed below.
2000 Lexus RX 300 awd: the tone ring on the right rear drive axle cracked causing a false reading to the anti-lock brake system, the cracked ring would not turn in conjunction with the axle causing the abs system to think that the affected axle was no longer tuning therefore activating the abs system and jeopardizing braking distance, after repairing I was wondering how this could have happened and did some inquiries, I found that this is a common problem on these vehicles (right rear axles awd models) water gets into the axle tone ring area, freezes causing the ring to crack and creating a dangerous condition, unnecessary activation of the abs system for the unsuspecting driver Lexus dealerships throughout the northeast keep these a supply of these very expensive axles in stock due to their familiarity if this problem.
