Cayenne Says It's Time for Differential Service at Allied Auto Works

cay

What time is it?  Cayenne here and for me it's always food or sleep time but your vehicle it could differential service time right here at Allied Auto Works.  So why you go check to see the last time you had that differential service we are going to bark about right now before we run out of time.  So let's get barkin'!

Hello Los Altos - let's talk differentials. If you have a rear-wheel drive vehicle, your differential is on the back axle. With front-wheel-drive cars, the differential is upfront. All-wheel drive and 4-wheel drive vehicles have three differentials - front, rear and in the middle. So you see, you've got a differential (or two or three) and it needs service now and then.

What does your vehicle differential do? Well, it compensates for the differences in speed between your outer and inner wheels in a turn. Using the dimensions of a typical car, let's compare the distance the wheels travel from the start of a turn through to the completion of the turn.

The inside wheel travels about 12.6 feet/3.8 meters. How much farther does the outside wheel travel? About 18.8 feet/5.7 meters – over 6 feet/1.9 meters more. This means the outer tire has to rotate 9 times in the same amount of time that the inner tire has to rotate only 6 times - so the outer tire has to spin faster in order to keep up. The differential makes this possible.

The gears in the differential are cooled and lubricated by differential fluid. It's this fluid that needs to be serviced. Small bits of the gears break off and are suspended in the differential fluid. The dirtier the fluid, the faster the gears wear.

So your Allied Auto Works technician drains the old fluid out and replaces it with fresh fluid. Some differentials also need a special additive that is put in at this time.

So when should you have your vehicle differential serviced? Intervals vary from vehicle to vehicle – and may be as short as 15,000 miles/24,000 km – so check your vehicle owner's manual or ask us at Allied Auto Works. If you frequently drive with heavy loads, tow a trailer or drive in hot CA conditions, you may need to change differential fluid more often. Servicing your differential on schedule at Allied Auto Works can save a pricey replacement down the road.

I am going to leave you with my positive quote for the day:  

"Believe in your best, think your best, study your best, have a goal for your best, never be satisfied with less than your best, try your best-and in the long run, things will work out for the best."
~Henry Ford
