WHAT WE SERVICE
The gear boxes under your truck
Each unit holds its own oil, separate from engine oil. Each is one service.
Differentials
The gears that turn your wheels. Rear-wheel-drive vehicles have one, and 4x4s have a front and a rear.
Transfer case
Sends power to the front and rear axles on 4x4s and many all-wheel-drive vehicles.
Manual transmission
Stick shifts run on gear oil too, and we change it the same way.
WHEN TO COME IN
When to change your gear oil
You're at the mileage
Your owner's manual lists an interval for each differential and the transfer case.
You tow, plow or go off-road
Heavy loads and heat wear gear oil out faster. Many manuals list a shorter interval for that kind of driving.
You drove through deep water
Water can get in through a differential's vent. Milky gear oil needs changing.
You hear a whine
A whine or howl from underneath is worth a look. Fresh oil helps healthy gears, and we'll tell you if we see more.
We check your differential and transfer case levels at every oil change. Every service earns a rewards punch: an oil change plus front and rear differentials is 3 punches.
HOW IT WORKS
Gear oil service, the honest way
1 · We check and show you
We check each differential and the transfer case, and show you the oil.
2 · You get the total first
You pick which units we do, and you know the price before we start.
3 · Fresh oil, coupon off
Your $20 comes off the total, and every unit earns a punch on your rewards card.
