Everything You Need to Know About Diff Reconditioning

Diff Reconditioning

What is diff reconditioning?

Every time your car takes a turn, have you noticed the movements of the wheels? When you take a left turn, the wheels on the right side of the car have a longer distance to cover than the ones on the left and vice versa for a right turn. This means the wheels which are supposed to cover a longer distance are supposed to turn faster than the other pair. Now, the question that arises is that how the car knows when to make a wheel faster than its counterpart. The part which makes this wizardry possible is the differential. The differential allows the wheels of the vehicle to rotate at different speeds in turns without any jerks and wheel binding. In the case of a rear-wheel drive vehicle, the differential is on the rear axle. In the case of a front-wheel drive vehicle, the differential function is handled by the transaxle. Also, all-wheel drive vehicles have differentials on both the axles. There is also a centre differential between the front and rear axles that compensate for speed differences between the front and rear. Because all the power of the engine is transferred to the wheels through the various differentials, it is one of the most important components of the car machinery and that is exactly why you need to maintain it in a perfect condition. That is why diff reconditioning is essential.

How does the whole process of diff reconditioning work?

  • Testing the diff case and diagnosing what is wrong comes first. This can be done without any major dismantling.
  • Then, the diff reconditioning process starts and the differential case is opened and it is stripped down and each part is inspected for damage.
  • Any unserviceable components are replaced with brand new parts if they are beyond repair and the rest of them are reconditioned.
  • Those that pass all the checks and tests are cleaned thoroughly and returned to the assembly.
  • All the metal parts are brushed and scraped to get rid of rust and scaling and its shiny surface is restored.
  • After all the parts are individually tested, reconditioned and then compiled and assembled back together.

With this, you get a differential case which has efficiency just like a brand-new model.

When to get diff reconditioning services?

In the majority of cars, the differential lasts throughout the life of the car without any need of diff reconditioning. However, in the case high-mileage vehicles, sometimes the differential begins to show signs of failing. Most differential problems occur in vehicles which reach more than 150,000 miles on the odometer. Often, the mechanic can solve the problems simply by adding differential fluid, but it is advisable to get a diff reconditioning as a precaution.When the differential starts failing, it usually starts by showing small signs that escalate with time if ignored. Look out for the below-listed signs in your vehicle to detect a differential damage.

  • As the differential is usually silent while working normally, any abnormal noise your car makes may be because of a flaw in the differential.
  • Keep your ears on alert for a whistling noise from your car. If you hear a high-pitched whistle or whine around the axle where the differential sits every time you take a turn, this is the first sign of differential trouble.
  • Keep checking for rumbles or clunks around the axle. This is a sign that the differential condition is already getting worse. You may occasionally hear this sound when you press on the accelerator pedal and more frequently when you are coasting.
  • If you feel a drag on the vehicle while driving, you need to consider it as an alarm. The car feels more sluggish when you’re coasting at low speeds and it might feel like you are driving on low tires.

If you feel any of these symptoms, DO NOT ignore them because if you do, you may experience a dangerous breakdown and also, your car is not safe to drive around with a differential in this bad shape. Get diff reconditioning services as fast as you can from a certified mechanic.
