What maintenance is required for the aFe differential covers?

The magnetic drain plugs should be inspected and cleaned periodically to remove any captured metallic particles. Refer to the manufacturer's instructions for recommended cleaning intervals. Also, inspect the oil level through the sight glass regularly and replenish as needed.

What if I need to replace the oil level sight glass?

The sight glass is replaceable. Contact aFe directly or your authorized aFe dealer for replacement part information. Be sure to have your part number (46-7703AB) ready when you call.

Do I need to add a friction modifier with this oil?

The included PROGUARD synthetic gear oil exceeds API GL-5 performance requirements and is suitable for both open and limited-slip differentials. You typically do not need to add a separate friction modifier, but always refer to your vehicle's service manual to confirm.
