NHTSA recall 97V056000
Power Train · Toyota Motor Corporation
Details
What's wrong: Due to a clearance between the oil separator plate and the differential housing of the front differential unit, oil leakage at the air breather plug can occur, when the vehicle is operated continuously above 75 miles per hour.
Why it matters: Oil leakage will result in a sufficiently low oil supply to cause bearing damage to the front differential unit leading to eventual seizure of the unit increasing the risk of a crash.
The fix: Dealers will install a modified air breather plug to prevent such oil loss.
