Viva la Differential

With front-wheel drive being so common these days, the differential is just taken care of during a transmission service at Judson's Auto Tech Inc, so most Montague drivers don’t even have to think about it. And most rear-wheel drive differentials don’t need to be serviced for many kilometers, so it’s understandable that it’s not something on the top of mind for Montague drivers. So it’s not uncommon for Montague drivers to not know they have a differential let alone know that it needs service.

To better understand what a differential does, think about a high school track. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That’s to compensate for the longer length of the outside lanes. Staggering the starting lines means that each runner has the same distance to run.

The differential compensates for the difference in speeds on drive wheels between the inside wheel and the outside wheel in a turn, because they have to travel together through slightly different distances.

Differentials do a lot of work for Montague drivers and require very heavy duty parts. And those parts need protection. The differential fluid lubricates the gears in the differential and keeps them cool. The fluid eventually gets dirty and worn down. Some kinds of differentials require special additives that breakdown over time. So automobile manufacturers recommend intervals for replacing your differential fluid.

Your Judson's Auto Tech Inc service advisor will drain the used fluid and check it out for metal bits, which could be a sign of excessive wear on the gears. He’ll then replace the fluid and install the additives if necessary.

Montague drivers's four wheel drive vehicles need special attention to their differentials because they have a differential on both the front and rear axles that work at different times and sometimes under heavy loads – so they may need to be serviced at different intervals.

Your Judson's Auto Tech Inc service advisor can look up the car maker’s recommended service interval or you can check your owner’s manual.
