Undercar Services: Maintenance & Repair

Rely on Pro Tune Plus in Bismarck, ND 58504 to provide quality care for your vehicle's undercarriage. Stop by our shop to see how we can help you or call 701-224-1638 for more information.

To keep your vehicle running at peak performance, we provide undercar services that include:

Anti-Lock Brakes
Anti-lock brakes prevent wheel lock-up when rapidly decelerating by automatically modulating the brake pressure during an emergency stop. With this system, the wheels are able to maintain traction with the road while braking. Failure of the anti-lock brakes could lead to an increase in the risks of multiple vehicle crashes and run-off road crashes. To avoid this, have your anti-lock brake system checked and repaired by experts. At Pro Tune Plus, we have anti-lock brake experts who will examine and repair your faulty ABS - keeping you safe.

Brakes
A brake is a mechanical device for slowing or stopping a vehicle (usually by means of friction). In short, a brake inhibits your car's motion. It lets you stop the car whenever and wherever you choose. Brakes are one of the most important parts of a motor vehicle. Without them, you would not be able to stop the car. If your vehicle's brakes are having issues, consider having them worked on. Brake experts at Pro Tune Plus can work on your car's brakes to ensure you have a safe drive.

Brake System Flush
Brake fluid is hygroscopic (it absorbs moisture). The absorbed moisture lowers the fluid's boiling point. It also corrodes the lines and cylinders. With the lowered boiling point, the brake fluid could boil during braking which makes you lose braking ability. Although this is an extreme scenario, it does happen in heavy braking. To reduce the effects of the absorbed moisture, auto manufacturers recommend that you have a brake flush done periodically. A brake system flush involves the replacement of used and contaminated fluid with fresh fluid. With Pro Tune Plus's quick lube services, you will have a brake system flush performed by brake experts. Call 701-224-1638 or visit Pro Tune Plus today.

Chassis
A chassis is the car's internal framework that supports the body and other parts like the wheels, engine, transmission, driveshaft, differential, and suspension. A weak or damaged chassis will translate to a weak car. To have a strong and properly working vehicle, have your car's chassis checked for defects. At Pro Tune Plus, there are experienced undercar service providers who can work on your chassis.

Differentials
The differential transfers the engine power to the wheels. One important function of the differential is to pass on power to the wheels while allowing them to rotate at different speeds - thus the name differential. When turning, the outer wheels travel a larger distance than the inner wheels do (also the front wheels travel a longer distance than the rear wheels). This means that all four wheels travel at different speeds during a turn and this is where the differential comes in to help. To make sure your vehicle's differentials are working properly, have them checked regularly. Contact Pro Tune Plus today for differentials examination and servicing.

Differential Flush
The differential is a car part that compensates for the difference in travel distance between the inner wheels and outer wheels when the vehicle is turning. Due to the differential's position in most non-four-wheel-drive (FWD) vehicles (located at the rear and under the car), it does not get any of the star treatment the engine gets. The one thing that every car owner needs to know is that failure of the differential will mean failure of the car. To save the differential from failure, you need to have differential fluid changed every 30,000 to 50,000 miles. Changing the oil on the differential is as important as changing the car's engine oil. Although checking and changing differential oil is pretty easy, you need to visit an auto shop to get a comprehensive differential flush. For differential flush services, visit or call Pro Tune Plus in Bismarck, ND 58504 today.

Exhaust
In a motor vehicle, an exhaust system is a piping used to guide exhaust fumes away from the engine - usually to the rear of the vehicle. A properly functioning exhaust system not only sounds better, it is better - for you, your car, and the environment. Pro Tune Plus has expert technicians to service your car's exhaust system.

Driveline
A driveline is a part of your motor vehicle that connects the engine and the transmission to the wheel axles. The driveline consists of the parts of the powertrain less the engine and transmission. Failure of the driveline means that the car would not move since energy cannot be transmitted from the engine to the wheel axles. Therefore, make sure that your car's driveline is regularly inspected and serviced. And, at Pro Tune Plus, you can have the driveline serviced by experts.

Tires
As tires get older, they lose traction and deteriorate from the inside out, increasing the likelihood of a tire bursting. This can cause a rapid loss of control of your vehicle. To have a better performing vehicle, you need to make sure the tires are in good condition. For all your tire needs, contact Pro Tune Plus today.

Shocks
Shocks (or shock absorbers) are mechanical devices designed to smooth out rough roads. The devices do this by converting kinetic energy to another form of energy. Properly working shocks reduce the effect of traveling over rough ground, leading to improved ride quality and vehicle handling. When shocks develop problems, driving on poorly leveled roads becomes unpleasant, and your vehicle may sway when turning. To have your vehicle's shocks diagnosed and repaired, visit Pro Tune Plus today.

Struts
Much like a shock absorber (shocks), your car's struts provide a dampening effect as you travel over a road's surface. By absorbing the shock of the road, struts allow passengers to ride in a car without constant and uncomfortable motion. Struts work a bit differently than shocks in that they provide structural support for your car's suspension. This means that struts support your car's weight, unlike shocks which only regulate the speed at which the weight is transferred. Struts usually last around 50,000 or 60,000 miles. This is simply because the damping characteristics of the parts gradually deteriorate over time. Call Pro Tune Plus at 701-224-1638 if you have questions about the struts on your car. Our expert technicians will diagnose any problems and help you make an informed decision about repairs.


What Our Customers Are Saying

These guys have been really great to work with and very honest. I haven't had a mechanic this good in years. So glad I found your place.


-Trudy J.

I highly recommend Pro Tune Plus based on my experience. I was driving from Virginia to Saskatchewan in January and my AWD system in my volvo xc 70 failed. I was stuck in a strange town and unsure of where to take my car. Both AAA and the staff at the Marriott Residence Inn seemed to think Pro Tune Plus would be decent. I was more than impressed with their service and the options offered in getting me back on the road. They did a great job; show impeccable attention to detail; and understood my need to get my car fixed and back to grad school quickly and cheaply. Fixing a Volvo in an area where there aren't alot of Volvos was scary for me but it worked out great!


-Rob P.

Excellent service! I went here to get my car checked before I moved back home and it was one of the best car services I've ever had. Joe was affable, professional, and efficient in his work. It didn't take long for the service to be finished, and he even put on some zip ties on the front of my ripped bumper to prevent it from getting damaged on the long ride home-for free! If you want quality service that's fast and professional, I highly recommend Pro Tune Plus.


-Holly B.

Absolutely incredible. Pro Tune Plus came through hard for us on our travels. We broke down in ND, are from Canada and Joe, Pat, Mayson and Nathan were the real MVP's who got us fixed up and back on the road in no time at all. Each one of them were SO compassionate, empathetic and did everything in their power to help myself and my friend get back on the road as quickly and safely as possible. Everything from personally driving us around town, and personally offering up a place for us to stay. Their efficiency and mechanic work is second to none and I would recommend ANYONE to not only get their vehicle fixed by Pro Tune Plus but to also even just have the pleasure of meeting these incredibly kind people. It was the best of a crappy situation to have had them come along our path. They give me faith in humanity and I from the bottom of my heart can't even put into words how wonderful of a business Pro Tune Plus is. Number one in North Dakota by a long stretch.


-Rebecca C.

Saved my Duck Hunt! Great people. Accommodated my two dogs while they fixed my van. Got me back on the road and had no further problems. I highly recommend this group for any travelers with car or truck problems.


-Rick T.

Service was awesome and if you haven't been here I recommend giving them a try. They were courteous and very professional. They diagnosed the problem and fixed it right the first time every time I have been here.


-Jason S.

Joe and the staff were fantastic! We were on a road trip on a time schedule and got to the shop later in the day. Without asking, Joe stayed an extra 45 minutes after hours so that we could continue with our trip. We even got to play some old school NES as we waited.


-Austin B.

What a great place! Got me in so fast. Was happy with all the work done for me. Such nice guys to know. Highly Recommend them.
