Do you think your car’s differential, also known as its back or rear end, may be going bad? One of the tell-tale signs of a bad differential is strange noise. While noises can be the result of many different vehicular problems, the sounds of a failing differential are usually quite obvious and distinct. If you hear a howling noise, a thudding or clunking sound, or a noise that sounds like whining, your differential is probably to blame. Many people with differential problems tend to experience these problems when their vehicles are turning corners, but the noises can really present at any time.
A truly troubled differential will often move past strange noises to full-on vibration. The vibration usually starts out as a slight humming sound and then gets worse and worse over time. If you feel like your entire vehicle is shaking and you can’t figure out why, it’s likely your differential. If left uncorrected, this excessive vibration can greatly decrease your speed on the road and can often be the first sign of an impending breakdown. When the differential is at fault, leaks often accompany the vibration.
Ideally, you would know about differential problems long before these signs would ever occur. The best way to spot differential issues early on is to regularly have your vehicle inspected thoroughly by a skilled and qualified mechanic. Mechanics are trained to detect these and other automotive issues in the very early stages, which is good since the earlier a problem is detected, the easier and less expensive it will likely be to fix.
The good news is that few vehicles are completely beyond repair. A differential rear end rebuild-repair can help almost any vehicle, providing it is done by a qualified, highly trained professional. Therefore, you should never just throw in the towel on your vehicle. Whether you’ve just discovered a problem with your vehicle’s rear end or whether you’re noticing symptoms like these described here, it’s not too late to seek help from the pros.
