The differential is the part of your vehicle's drive-train that enables your left and right wheels to turn at different speeds when making turns while still maintaining control. The differential is positioned between two wheels and attached to each wheel by an axle shaft. Without a differential, your vehicle would bump along the road. Whether your vehicle has a four-wheel drive, front wheel drive, or rear wheel drive, its differential experiences heavy wear and tear. Maintenance for differentials will differ every vehicle depending on where you drive most often and how much time you spend on various types of terrain. At the first sign of problems, such as noise coming from your vehicle's differential, contact Gearmaster as soon as possible to diagnose and fix the issue.
Differential Fluid Change
Differential fluid lubricates the differential in all-wheel drive (AWD), four-wheel drive (4WD), rear-wheel drive (RWD), and front-wheel drive (FWD) vehicles. The fluid in your vehicle's differential plays an important role in keeping the ring gear, pinion gears, and axle bearings lubricated and cooled. The technicians at our Gearmaster in San Jose, CA recommend changing your differential fluid every 15,000 to 30,000 miles.
If you suspect a problem with the differential in your vehicle, bring it to our San Jose transmission shop and one of our certified technicians will do a complete differential diagnosis to determine the problem.
Heat from friction gradually causes the differential fluid to break down, making it harder to keep the differential properly lubricated. Degraded differential fluid causes poor differential performance, excessive noise, and disproportionate wear. Be sure to perform routine maintenance on your differential system as indicated by your owner’s manual to avoid the expensive cost of replacing your entire differential system just because of old fluid. Depending on your vehicle's needs, when you come to Gearmaster for a differential service, components of your differential system will be checked and if necessary, repaired or replaced to keep your vehicle running efficiently.
