Car trouble doesn’t have to be an expensive inconvenience if caught before the problem worsens. Warning signs can tell you when to hire an experienced mechanic for auto repair. The differential, for example, is an essential component that often needs professional attention. Here’s what you should know about your car’s differential and how to tell it needs service.

What Is the Differential?

Have you ever watched a track race and seen how the runners on the inside of the curve are positioned farther back than those on the outside? This is because those on the inside have a shorter distance to run. The same is true of your car’s wheels when you make a turn. The wheels on the outside of the turn must rotate more times than those on the inside, which puts stress on the vehicle.

The differential is a mechanical system that compensates for this difference, allowing the outer wheels to rotate the necessary number of times so your car can handle the turn. They affect the drive wheels of your vehicle, whether it’s rear-, front-, or four-wheel drive. The differential undergoes a lot of stress, which is why it’s important to watch for signs that it needs maintenance.

What Are the Signs It Needs Auto Repairs?

Fluid helps cool and lubricate the gears inside the differential. Your mechanic should check these levels during service to make sure the fluid isn’t leaking or dirty. Dirty liquid can wear down the gears faster, while a leak can reduce fluid and expose the gears to more friction, shortening their life span. Ask your mechanic to check the pinion seal, which is meant to keep the differential fluid from leaking. If the rubber on this seal appears worn, there may be a leak.

Another sign your differential needs auto repairs may be a strange noise from your vehicle’s axle. You may also hear clanking when you turn your vehicle on and put it in drive, or the sound of grinding gears when you accelerate quickly. This indicates the differential gears are stripped and should be immediately repaired. If you ignore this problem, you could lose control of your vehicle while driving.

You can extend your differential’s life span with routine checkups. If you need professional help around Kailua-Kona, HI, Precision Auto Repair services all vehicle needs.
