Simple Answers from Robert's Auto Repair for Port Isabel: Differential Service

Question:
What is a differential and why do Port Isabel drivers need to have it serviced?

Robert's Auto Repair Answer:
First of all – your vehicle does have a differential. If it's a rear wheel drive, your differential is on the back. If it's front wheel drive, your differential is built into your transaxle (transmission). Port Isabel drivers with all wheel drive or four wheel drive will have differentials front and rear and maybe one in between.

When you are steering through a turn at an intersection in Port Isabel, the wheels on the outside of the vehicle have to spin faster than the inside wheels because they have to travel a slightly longer distant through the curve. The differential compensates for these speed differences between the wheels.

Because it is part of the equipment that transfers engine power to the wheels, the differential is working pretty hard. Differential fluid – a special heavy-duty oil – cools, lubricates and protects the differential. It needs to be replaced on a schedule to remove metal shavings and other contaminants. Note: if you have a front wheel drive vehicle, replacing your transmission fluid takes care of your differential service needs.

Differentials have become increasingly sophisticated for Port Isabel drivers. Rather than the simple mechanical devices of yesteryear, they are more complicated and may actually be part of the computer controlled vehicle stability system. This means they are more taxed, so it pays for Port Isabel drivers to have them serviced on schedule at Robert's Auto Repair in Port Isabel to avoid premature wear.
