Differential

Stay in Control with Expert Differential Service

If your vehicle has ever made a strange noise or felt shaky when turning, chances are you have experienced differential issues. The differential is the component of your vehicle that makes it turn and swerve around corners smoothly. It works by allowing the wheels on your vehicle to rotate at different speeds, which is necessary for navigating turns and curves without losing traction.


However, like any other mechanical component, your vehicle's differential needs regular maintenance. Otherwise, it may wear down over time, resulting in breakdowns or expensive repairs. Hi-Tech Auto Specialists is the go-to destination for a differential service to prevent significant issues down the road (both literally and figuratively).

What Does a Differential Service Include?


Most drivers don't think about a differential service until they experience problems with their vehicle's handling. However, regular maintenance saves you from expensive repairs and rough rides.


When you bring your vehicle to Hi-Tech Auto Specialists for a differential service, a mechanic will do a differential inspection to check for leaks, worn-out gears, or any other signs of trouble. They will conduct necessary repairs to prevent further damage if they detect a leak.


Then comes the differential fluid change — or differential fluid flush if it's really dirty. Over time, this fluid breaks down, which can lead to excess friction and wear. A fresh differential oil change keeps everything running smoothly.


If your vehicle has a limited-slip differential or a locking differential, the right fluid is extra important to prevent damage. These vehicles require specific additives to maintain proper operation. Since Hi-Tech Auto Specialists carries a wide range of differential fluids, we can match the right one to your vehicle for a limited-slip differential service.


Your vehicle might need a rear differential service, a front differential service, or both. The former is more common. But the latter might be necessary if you drive a high-performance vehicle or an all-wheel-drive (AWD) or four-wheel-drive (4WD). A front differential service is similar to a rear differential service, except for the location.


Some other services Hi-Tech Auto Specialists provides are:


  • Differential Gear Service: The mechanic will check the differential gears for signs of wear and tear, such as chipping or cracks. If needed, they will replace them with high-quality gear.
  • Differential Seal Replacement: The service is needed if the differential seal is leaking. Replacing the seal helps prevent further leaks and keeps the differential fluid at the correct level.
  • Differential Fluid Level Check: The mechanic will check the fluid level and top it off if needed.


At Hi-Tech Auto Specialists, we specialize in all things related to differential maintenance and repair. So, as soon as you notice any strange noises or vibrations coming from your vehicle, make an appointment with us to have it checked out.


Warning Signs That A Differential Needs Service


How would you know when to bring your vehicle to Hi-Tech Auto Specialists? Here are some signs.


  • Poor handling: If your vehicle is having trouble turning or feels like it's pulling to one side, something may be wrong with the differential. A locking differential service may be needed to restore smooth performance.
  • Whining or Howling Noises: If you hear a high-pitched whine while driving, especially when turning, the differential might be low on fluid and due for a differential oil change.
  • Burning Smell: Overheated or old differential fluid can cause an intense burning odor. Take this as a signal to take your vehicle in for differential repair or maintenance, whatever it needs.
  • Grinding and Clunking: These could mean worn-out gears requiring differential repair. However, a differential rebuild will be necessary if the damage is severe.
  • Leaks: Spot some fluid under your vehicle? It could be a differential leak. Bring your vehicle in to have it checked by our expert mechanics.


If you ignore these warning signs, they could become more concerning issues. Instead, let the mechanics at Hi-Tech Auto Specialists diagnose and repair your vehicle's differential problems in a timely manner.
