What You Should Know About Differential Service and Repair

Discover what you need to know about differential service and repair and learn what Mister Transmission can do for you and your vehicle’s differential.

What Is A Differential?

All automobiles have a differential. It compensates for the difference in distance the inner wheels and outer wheels travel as the automobile rounds a corner. In a rear-wheel-drive vehicle, the differential has its own housing and lubrication. For a front-wheel drive vehicle, the differential is often integrated in the transmission housing and it shares the same fluid. In an automatic or continuously variable transmission, this would be automatic transmission fluid. In a manual transmission, it could be automatic transmission fluid, hypoid gear oil, engine oil, or transmission oil.

The lubrication is needed for the ring and pinion gears that transfer power from the driveshaft to the axles. If your vehicle has a limited-slip differential, the lubrication also keeps the moving parts in that assembly healthy. Because the differential might be in the same housing as the transmission and use the same lubricant, many transmission shops, such as Mister Transmission, also offer differential service and repair.

Differential Service And Repair

As with pretty much any auto part that requires lubrication, that lubrication is key to maintenance and repair. Good maintenance means ensuring you have the right amount of lubricant and the right quality of lubricant. At Mister Transmission, we can ensure your differential has the fluid it needs to operate smoothly, whether that’s transmission fluid or another lubricant.

However, if you’ve been driving around with too little differential lubricant, you’re going to have problems. You certainly wouldn’t be the first to make this error, but it can have severe consequences. Without lubricant, the differential can grind down and suffer from all the friction it endures. In the worst cases, this can necessitate a complete replacement.

Signs Of A Bad Differential

How can you know if your differential needs a repair? There are a few telltale signs. The first is noise. If you hear a whining sound, especially when you turn, there’s a good chance that your differential is lacking lubricant.

Uneven tire wear and bad handling are two other common symptoms. A malfunctioning differential means the inner wheels on any turn have to spin faster, reducing tread life. A bad differential also makes it more difficult to steer. Last, excessive vibration or grinding may also indicate a bad differential.

Robert Belicano
I had a great experience with Mister Transmission regarding repairs to my Toyota FJ Cruiser, Ken the master mechanic, was extremely knowledgeable, informative, and took time to explain the repairs clearly. Ken was awesome to work with, and I really appreciated his professionalism, honesty, and quality of service. It's not always easy finding a mechanic you feel confident trusting with your vehicle, but my experience here was excellent. I would definitely recommend Mister Transmission and Ken to my family and friends. Thank You for taking great of my FJ Cruiser.

Dan was extremely helpful, and patient with me- through all of my concerns, questions, etc. He dealt with my warranty company and took care of everything. With something that I've been battling for well over a year, trying to figure out what was wrong with my car, he took all my concerns and description of symptoms and was able determine the wear on my transmission. Not only that, but in my experience dealing with my car, there aren't very many places that are knowledgeable with the CVT tranmissions like he is. He rebuilt my transmission and saved me a LOT of money. I was also pleased with the customer service aspect- he updated me and checked in throughout the diagnosis and repair.

Richard Vander
After a follow up of a previous transmission service, the transmission had an unexpected error.It seemed there was a possibility that it was covered under warranty.Upon learning, it wasn’t under warranty, the quote was less than the normal book rate.Also, the part that came in was more than was anticipated as well, but Mister T absorbed the difference.Thanks guys
