Undercar Repairs in Tucson

At Tucson Transmission Auto & Diesel Repair, we focus on the health of your car or truck from the ground up. Before evaluating the internal systems, we ensure that the vehicle has a solid foundation. Our comprehensive undercarriage inspections and services target this crucial, yet often overlooked, area to provide the necessary care your vehicle needs.

Avoid costly issues by bringing your vehicle in for an undercarriage inspection today. Call us at 520-888-2790 or stop by our Tucson, AZ location to schedule your appointment and keep your car running at its best! Our competitively priced undercar services include:

Chassis
The chassis serves as the internal framework of your vehicle, providing support for various components such as the wheels, engine, transmission, driveshaft, differential, and suspension. A weakened or damaged chassis can lead to a weaker vehicle overall.

Custom Exhaust
A motor vehicle's exhaust system consists of piping that guides exhaust gasses from the engine to the outdoors. While its primary purpose is the removal of exhaust gasses, it can be modified to enhance engine power, reduce pollution, and minimize noise. Achieving these goals necessitates undercar service installation of a custom-made exhaust system.

Differential Flush
The differential is a critical vehicle component that compensates for variations in travel distance between the inner and outer wheels during turns. Typically located at the rear and under non-four-wheel-drive (FWD) vehicles, differentials often do not receive the same level of attention as engines. However, it is essential to understand that differential failure equates to vehicle failure.

Differentials
Differentials serve as the components responsible for transmitting engine power to the wheels. A key function of the differential is to distribute power to the wheels while permitting them to rotate at varying speeds, thus earning its name.

Driveline
The driveline represents a vehicle section that connects the engine and transmission to the wheel axles. This component consists of powertrain parts excluding the engine and transmission. A driveline failure translates to an immobilized vehicle, as energy cannot be transmitted from the engine to the wheel axles.

Shock Absorbers
Shocks, or shock absorbers, are mechanical devices engineered to smooth out rough road surfaces. They achieve this by converting kinetic energy into another form of energy. Properly functioning shocks minimize the impact of traveling over uneven terrain, leading to an improved ride quality and enhanced vehicle handling.

Struts
Much like shock absorbers (shocks), struts serve to dampen the effects of road surfaces as you drive. By absorbing road shocks, struts enable passengers to experience a smoother ride. Struts differ from shocks in that they provide structural support for your vehicle's suspension.

Suspension FAQs


What happens if I only replace one strut or shock?

If you replace only one shock or strut, it will create poor handling when changing lanes or driving over bumps. If your car is new, replacing only one strut or shock absorber may be ok since the opposite side shock is not worn out yet. Generally, Tucson Transmission Auto & Diesel Repair recommends replacing both shocks or struts.

Are shocks difficult to replace?

Shock absorber replacement is usually a straightforward job, taking less than an hour of labor, but they should be replaced by a professional. Some models require other components to be removed or replaced before working on the front shocks. Bring your car to Tucson Transmission Auto & Diesel Repair in Tucson and we will help you determine what needs to be done and get you back on the road quickly.

How often should shocks be replaced?

Experts recommend that shocks be replaced at 50,000-100,000 miles. If you are a more aggressive driver or frequently drive on rough roads, they will wear out faster. Shocks don't go out all at once, they deteriorate slowly over time. If you are noticing problems with handling, making smooth turns or ride smoothness have one of the professionals at Tucson Transmission Auto & Diesel Repair inspect your shocks.

Are struts difficult to replace?

Replacing struts is simple and fast for a professional. Replacing your front struts yourself is not recommended, especially if you need a new complete strut assembly kit. When you get your truck's struts replaced you also need to have the front-end alignment checked. Ask the professionals at Tucson Transmission Auto & Diesel Repair to replace your struts and we will complete the work quickly and easily.

Maybe the best Transmission shop in AZ? I'm on Vacation and become in trouble with my rear end. Asked two other shops, one offered an appointmend next month, the other was not interested. Mike told me: "come in, we will have a look" Finaly: Plenty of Experience in the house, a great team with heart and soul for screws and nuts, the Differential of my 2005 GMC Sierra 2500 HD runs smooth and quiet again now. They changed all diff- and rear wheel bearings and it took only three days. Professional Service! And so AIRSTREAM and me can create more memories on our Roadtrip. Thanks to Mike and the Team for make all these posible! Kept you in best memories.

We are extremely satisfied with Tucson Auto and Diesel! My husbands truck was pretty much dead and Josh the owner contacted us through Facebook and got us in the very next day! We had some trouble getting our truck there, but nonetheless we got it there. We expected our truck to be out for a couple days considering we had just dropped it off, and they got it back to us the same exact day! If I could recommend anyone to go anywhere for their trucks it’s this place! 10/10 experience!

Holy Cow! This place knocks it out of the park. Super friendly staff especially the greeters at the front desk. The cost for my KIA Transfer Case replacement was very reasonable compared to the "crooks" at Royal KIA service department. I will be going back here for sure, highly recommended.
