Oil Changes and Tyre Pressures

Howdy folks! My name is Tony and this is my latest blog. For some time, I have been trying to think of what my new blog should be about. It was yesterday when I realised that the topic had been in front of me all along. The biggest thing I have learnt recently is how to service my car. I didn't believe in auto servicing. I thought it was the kind of thing people talked about but never did just so they seemed smart. Well, I didn't feel very smart when I broke down at the side of the road. The mechanic was kind enough to teach me all of the top tricks about how to maintain a car.

Why You Need to Investigate Any Strange Noises Coming from the Back of Your Car

Vehicle manufacturers have invested a lot of money and effort into making the car that you drive as quiet as possible. To do this, they have paid a lot of attention to aerodynamics and soundproofing, while also fitting exhaust systems that adequately muffle the noise. Therefore, you're able to conduct a normal conversation with your companion when driving down the road, but also become aware of unusual noises rather quickly. If something at the rear of the car has caught your attention, what could this be and why is it important for you to take action now?

Zeroing in on the Differential

While a noise from the back of the car could be associated with suspension issues, it's likely to be related to the differential. This is one of the most important components of the car, but also one of the most hard-working. A number of different mechanical noises could emanate according to what's going wrong.

Deciphering the Noise

When you are accelerating the car, do you notice a whining or grinding noise? Typically, this means that the teeth that are part of the various cog mechanisms are engaging incorrectly, or at the wrong angle. The noise may get worse when you take your foot off the accelerator, which indicates a more advanced version of the same problem.

The axle shafts that connect the wheels to the differential can sometimes wear out, which will in turn develop a knocking or clicking sound. It is possible, however, that such a noise only appears when you're going around a corner. Bearings within the differential casing could be wearing out and the problem is exacerbated when the unit is under pressure., Alternatively, you may find that the outer bearings contained within the road wheels are the culprit, which is somewhat simpler to fix.

Why Do These Problems Arise?

When you consider how hard the differential has to work, it's not surprising that things start to fail over time. Remember, this part of the car is converting energy created by the engine into forward motion. This energy has to be "stepped down" and turned through ninety degrees, all of which requires very precisely engineered tolerances and metalwork that's under constant pressure.

What to Do Next?

Any type of noise emanating from the differential is potentially problematic and you should book the vehicle in to your service centre as soon as possible. With an eye to the future, understand just how crucial the diff lubricant is and ensure that it is checked or replaced periodically to safeguard all components.
