finger tight and then tighten in a crisscross fashion to 18–22 ft. lbs.
8. Let the RTV sealant cure per manufacturer’s recommendations prior to the next step.

Caution
Each AEV differential cover can be used in either the front or rear axle locations and has two oil fill level
holes labeled “F” for Front and “R” for Rear to aid in servicing. Depending on what axle you are servicing,
use the appropriate hole as a quick reference when adding oil. All oil quantities should match the opera-
tor’s manual recommended amounts and weights. Always service differentials on flat level ground with
wheels chocked.

11. Lubricate and install the AEV provided O-Ring onto the AEV fill plug and install into the differential
cover and secure by torqueing to 25 ft. lbs.

Note
AEV recommends using a RUST-OLEUM type automotive Scratch & Chip Repair paint (Universal Flat Black
& Silver Satin) to preform minor repairs on chips and scratches that occur during off-road driving. Re-
move existing rust and apply paint as recommended by the manufacturer in the affected area to prevent
any additional corrosion or chipping.
