Differential Repair In Louisville, KY

Every car and truck on the road today has some sort of differential. Some are built into the transaxle while others are separate components that connect the transmission output to the drive wheels.

But what exactly is a differential?

When you turn a corner, the wheels on the outside of the turn drive farther and rotate faster than the wheels on the inside. The differential is what allows the drive wheels to turn at different speeds while still supplying torque to the wheels.

To do this, the differential uses a series of gears that can rotate in relation to one another while still transmitting power.

Sure, it sounds complicated, but it’s an important part of what enables your car or truck to drive around a curve without having the tires skip and slide along the road.

The good news is that there’s really only one thing you need to know when it comes to your car or truck’s differential: The technicians at your local Cottman center understand everything there is to know about differentials… even the limited slip differentials used in many of today’s cars or trucks. They know how to test them, and they know how to fix them when they aren’t working properly. Everything from a simple leak to a complete rebuild, the technicians at your nearby Cottman center can find and fix the problem, and get your car back on the road, fast.

Think your car may have a differential problem? Not sure what’s wrong? No problem: Call your local Cottman center and let them know what your car’s doing. They’ll check your car, and if it’s the differential, they’ll let you know exactly what it’ll take to get it your car working the way it did the day you drove it off the showroom floor.

    • Last year we had a transmission that needed to be rebuilt in a 2009 Subaru Forester and brought it to Cottman based on their reviews. Greg and his team were sympathetic to the huge repair bill I was going to have, and looked for any way to safely save money. We also went ahead and replaced the timing belt and water pump based on the mileage. Having never been there before I called a few places to check that their estimate for that wasn't too much. The price was right in line with other reputable shops. 1 year later the transmission is still shifting as it should. Recently the same car had several other issues come up and I decided to try a shop down the street for diagnostics. Some of the numbers seemed a bit steep, so I took the car to Cottman for a second opinion. Greg, John and crew confirmed the issues, but the cost of the repairs seemed on par with my Google searches and I really felt comfortable having the work done there. I told them I need the car to be able to take a trip to Chicago and back, and they listed everything out in order of importance/ safety. To some it up, when we drop our cars off at Cottman, I don't feel like I'm being up sold a bunch services the vehicle doesn't need. And they stand by their work!

    • Have used Cottman transmission several times now on 1998 E150. Always professional, honest & fair priced. Greg will take the time to talk & explain the repairs needed even though the shop is busy. Would be my 1st recommendation to a friend needing repairs!

    • We love Greg and his team. They do a great job with our older vehicles, and they don't nickel and dime us. They are very honest about what needs to be fixed now, and what still has life in it.

    • Cottman handled my manual clutch replacement with exceptional service. After replacement, the truck drove like new again with the exception of a newly leaking axle seal. Cottman continued to take the truck in to resolve at no additional charge. Exceptional service and communication throughout the entire process. I highly recommend.
