TR4/4A – Rear Axle Oil Leaks Due To Pressurization

by Phil Allen

To prevent rear axle internal air pressure build-up and subsequent axle shaft and pinion oil seal by-pass/leakage, always clean the air vent “bore-hole” when checking the rear axle oil level. (vent is located on the right hand upper section of the axle housing adjacent to the rear axle differential cover)
