Symptoms of a failing Differential
Driving feel is off
Notice any weird feelings, such as shudders or vibrations in the front or rear of your vehicle while driving or while turning a corner? This can indicate poor functionality of the differential inside the transmission system. Try to be observant while you’re driving. Not only will it make you a safer and smoother driver, but it will allow you to spot things that you might need to replace as soon as they go awry.
This shouldn’t be news to you, but weird sounds coming from your vehicle usually aren’t a good thing. The gears or bearings inside the differential might whine or make other abnormal noises when the unit is on its way out and in need of a replacement. Furthermore, unusual sounds could be due to a low fluid level…which brings us to our next symptom.
Sounds simple, but you should occasionally check for fluid leaks coming from the transmission. Those gears like to be bathed in fluid all day, every day. Make sure they live in the oily spa they deserve.
Car doesn’t move
If your differential has failed completely, power can’t be transmitted to the drive wheels to move your vehicle. Have you ever tried operating a car that doesn’t move? Not so fun is it?
