At Hendersonville Muffler and Brakes, we’ve seen it all — from worn brake pads to rattling exhaust systems. But there’s one crucial service many drivers overlook until it’s too late:
Changing your differential gear oil.
If you’re driving around Sumner County and haven’t thought about your gear oil in a while (or ever), this one’s for you.
🚘 What’s Differential Gear Oil, Anyway?
Your differential is the system of gears that allows your wheels to turn at different speeds — like when you take a corner. It’s what keeps your ride smooth, stable, and safe.
That system needs differential gear oil to lubricate the gears, reduce heat, and prevent wear. Over time, that oil breaks down or gets contaminated — and if it’s not changed, the damage adds up.
⏱ How Often Should You Change It?
Every vehicle is a little different, but here are general guidelines:
-
Conventional gear oil: Change every 30,000–50,000 miles
-
Synthetic gear oil: Lasts up to 100,000 miles
If you tow, haul, or drive in extreme temps, you may need service even sooner. That’s why we recommend having it checked during your regular oil change.
💬 “Most people have never had it done — and don’t realize the risk they’re running,” says Justin Hunter, owner of Hendersonville Muffler and Brakes. “We check it on every inspection because the damage can get expensive fast.”
🔥 What Happens If You Don’t Change It?
If you ignore your gear oil for too long, you might notice:
-
Clunking or whining noises when turning
-
Vibration or rough handling
-
Burnt smell from the rear axle
-
Increased wear on your differential gears
-
Repairs that cost $1,500+ compared to a simple service
