Differential Service That Keeps You in Control

A vehicle’s differential may not get as much attention as other parts — but when it’s not working right, you’ll feel it. From strange noises to shaky turns, differential issues can affect your vehicle’s handling, balance, and ride comfort. 🚗

At Hi-Tech Auto Specialists, we specialize in differential maintenance and repair, helping you stay safe and in control on the road. Whether you need a fluid flush or a full rebuild, we’ve got the tools and the know-how to keep your ride smooth and reliable. 🔧

Understanding Your Vehicle’s Differential

The differential plays a crucial role by allowing your wheels to rotate at different speeds — especially important when turning. Without it, your tires would skid through every corner, making the ride rough and your tires wear out faster.

Depending on your vehicle, you might have a  rear,  front, or all-wheel drive system — which means different types of differentials. And just like your engine, it needs regular care.

At Hi-Tech Auto Specialists, we work on all types of differentials and offer complete maintenance services to prevent costly damage down the road.

What’s Included in Differential Service?

Proper differential maintenance helps avoid wear and tear that can lead to serious repairs. Our team at Hi-Tech Auto Specialists can perform:

🔧  Differential fluid change  – Old fluid breaks down and leads to friction. We replace it with the correct grade for your vehicle.
🔍  Differential inspection  – We look for worn gears, damaged seals, or leaks.
💦  Differential fluid flush  – If fluid is dirty or contaminated, we do a full flush and refill.
⚙️  Gear and seal service  – We check for chipping or cracks and replace seals if needed.
🔄  Front & rear differential service  – Whether you’ve got AWD, 4WD, or RWD, we handle both.
🛠️  Limited slip & locking differential service  – These require special fluid and care. We’ve got it covered.
📏  Differential fluid level check  – Quick check to make sure you’re not running low.

Whether it’s a simple oil change or a complete differential rebuild, our experts ensure everything is functioning properly.
