To obtain a proper chamfer for a good seal installation, deburr the right side axle housing seal bore using a standard deburring tool (1), such as
DEBUR300 from Snap-On, EO1000 Edge Off from Noga, SHAVIV by Vargus or the equivalent.
It is necessary to remove the exhaust system and the right rear wheel drive shaft. Refer to Rear Axle Shaft Seal and Rear Wheel Drive Shaft Flange
Replacement in SI to allow room to perform the following service procedure:
Place a clean, lint-free shop towel inside the right side differential seal bore to protect the bearings from any chips created by this process.
Using a deburring tool, chamfer the outer edge of the right axle housing seal bore (1) approximately 3-6 times or until a smooth chamfer of 1.5 mm (0.06
in) depth is created.
Clean off any chips from the housing area.
Remove the shop towel.
Visually inspect that all chips have been removed and that no burrs or sharp edges remain on the chamfer (1).
Follow the regular seal installation procedure. Refer to Rear Axle Shaft Seal and Rear Wheel Drive Shaft Flange Replacement in SI.
