Undercar Services: Maintenance & Repair

Undercar Repairs in Defiance

At Northwest Automotive LLC, we take a holistic approach to vehicle care, beginning with a thorough evaluation of your car or truck's foundation. Prior to inspecting the internal components of your vehicle, we prioritize ensuring that you have a strong undercarriage.

Our comprehensive undercarriage inspections and services address this vital but often overlooked area of your vehicle, affording it the care and attention it deserves.

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


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 Northwest Automotive LLC 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 Northwest Automotive LLC to replace your struts and we will complete the work quickly and easily.

Is it necessary to get an alignment after strut replacement?

Northwest Automotive LLC recommends performing an alignment anytime shocks, struts or other steering and suspension components are replaced. Getting your vehicle's alignment within factory specifications ensures optimal tire wear and helps prolong the life of your tires.

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, Northwest Automotive LLC recommends replacing both shocks or struts.

I have a 2011 Jeep Liberty, the A/C stopped working, so I called up Tim and told him. He said can you bring it in today at 1:00pm? I said yes. So I took it in, they found that all the Freon was out of the unit. So they put more Freon in plus added some dye to find if the system may have a leak. So I paid the bill. Tim said, if you have any further problems bring it back. So the next day I started my Jeep up. The A/C stop working. So I called them back on Saturday. Can you bring it back on Monday at 2:00pm? I replied yes. Returned back to Northwest Automotive. They took my jeep in and recharged the A/C unit, and checked the system for any possible leaks. So Tim filled me in on no signs of dye so go ahead drive it and if any further problems bring it back. So how much money do I owe you? He replied nothing. The next day I drove my Jeep the A/C stop working again. So I called them back and told them. Can you drop it off so we can get to work on it Monday morning. I said yes. So I called them up Monday around noon and asked how are things going with my jeep? He replied that we believe we have found the leak. So he asked you said when it would set over night that the next day it not work? I replied yes. He asked if you don't need your Jeep back today, we will let it set overnight and check and see if it is still working in the morning. So I replied yes. I called them back the next day and asked how are things going with my jeep? Tim replied it is working fine. He asked if I would pick it up later today, l said that is fine because I will not be in town till around 3:30pm. Because I was at work. So went to pick up my Jeep. Tim said I believe the problem was from the low pressure valve. It should be alright. I replied so how much do I owe you. He said nothing, if you have any further problems bring it back. I believe he is a fair and honest person. I will respect that and I will bring him some more business. Thanks again.

Northwest Automotive didn't charge me to look over my Geo Traker, even though I didn't end up having anything done to it. Will be going back to them.
