While Jaguar is known for offering maximum power, amazing performance, and tight handling, it can also develop issues with the rear differential. This shouldn’t detract from the overall driving experience of this brand of vehicles, as the Jaguar’s innovative suspension is well-known and highly regarded by car enthusiasts. However, it is definitely something worth bearing in mind as a Jaguar owner.

Rear differential problems are common in Jaguars of all years, and how you approach resolving the issue will depend upon the age and model of the model you drive. Let’s explore rear differential problems further and discuss why you need to respond to them in a timely manner.

The Purpose of the Rear Differential

All vehicles will have a differential within their suspension systems. It is needed to control wheel movement when turning. The regulation of wheel movement and shift works to counterbalance the inner and outer wheels when cornering. Almost all Jaguars use an independent rear suspension, which features a limited-slip differential, with the exception being recent models.

Because rear differentials are actively working with literally every corner you take, the differentials need constant care in order to stay in working condition. This maintenance comes in the form of lubrication which helps extend their lifespan and increase their performance.

Different Types of Differentials

As mentioned, there are several different types of differentials on the market with most Jaguars favoring the limited-slip differential. However, it is worth bearing in mind that your Jaguar may use a torque-vectoring differential instead. Having this information at your disposal is important when it comes to knowing what warning signs to look for and how to deal with them should they arise.

Factors that can Cause Differential Failure

The cause of differential failure in your Jaguar really does depend upon the age and model of the brand that you drive. Warning signs may vary depending on whether your Jaguar uses limited-slip differential or torque vector differential, so keep this in mind. By and large, there are two main causes of differential failure, which are as follows:

1. Oil Contamination

As we learned earlier, differentials require lubricating oil to function correctly. Different oil helps to protect these hard-working parts from accelerated wear and damage. Therefore, if the oil becomes dirty or contaminated, it will start to fail. This can result in the differential becoming worn out entirely. While differential oil does need to be changed, this doesn’t need to occur as frequently as motor oil. It should be changed out at the discretion of your trusted mechanic.

2. Faulty Differential Gasket

The differential gasket keeps the much-needed differential oil from leaking. With time and use, the different gaskets can become worn out, and their seal can begin to crack or slacken, allowing oil to seep from the system. When this happens, the gaskets need to be replaced. This is a simple fix for an experienced mechanic who has the industry knowledge of your year and model of Jaguar. This repair is an affordable repair at your expert technician’s shop.

Don’t Ignore Differential Failure

Your Jaguar’s suspension is designed not only to provide you with comfort when you drive but also to keep you and your passengers safe. The suspension is what keeps your car level and balanced. It stops your car from rolling when you take sharp corners, and keeps it stable when on bumpy roads. Therefore, any type of part failure which compromises the function of the suspension should be viewed as a safety concern that should not be ignored.

Remember, rear differential failure is easy to fix, so it’s not worth risking the lives of you, your family, other motorists, and pedestrians for the sake of a single part.
