Differential Service

Gearbox fluid provides lubrication for the sets of bearings, shafts and gears located in the different types of gearboxes which operate under high stress and high heat. Kwik Kar recommends differential service every 12,000 miles or 12 months if towing heavy loads or submerging rear-end in water. Otherwise, see owner’s manual for suggested interval.

What we do:

Remove and inspect the fill plug

Remove and inspect the drain plug

Flush and vacuum the old gear oil out of the gearbox

Reinstall the drain plug

Fill the differential with up to 5 pints of new gear oil

Reinstall the fill plug

Why we do it:

Helps protect against bearing and gear failure

Prevents abnormal wear on gears due to poor lubrication

Prevents gear overheating
