Gary's Full Service 
Auto Repair LLC

Gary got his start with trucks - the big ones! For years before he opened his own shop, Gary kept commercial over-the-road trucks hauling down the Interstate. He knows from personal experience what it takes to keep your beefy 4-wheel-drive or all-wheel-drive vehicle doing what you want it to do. Your hard-working vehicle requires more maintenance and has more moving parts than a little around-town sedan.

Transfer Case
Servicing the transfer case when recommended by the manufacturer, or when the fluid gets dirty (whichever comes first) will help to prevent stiffness while shifting, reduce chain and gear wear and prolong the life of transfer case bearings and seals.
We use only manufacturer-specified fluids to service your truck's transfer case!

Front & Rear Differential
Servicing your differentials when recommended by the manufacturer, or when the fluid gets dirty (whichever comes first!) will help protect differential and pinion bearing, axle bearings, ring & pinion gears, spider gears and seals from premature wear. Failure to change the differential oil can lead to some very expensive repairs!
We use only manufacturer-specified fluids to service your truck's differentials!

Drive Shaft (U-Joints & Slip Yokes)
Hauling heavy loads or running off-road puts a lot of demand on drive shaft parts. Bad universal joints can damage the transmission tail shaft seal and bushing, rear pinion seal and pinion bearings. Damaged slip yokes can cause vibration and noise. In extreme cases, a damaged U-joint or slip yoke can cause the drive shaft to come apart - and even fall out!
We will inspect your truck's drive shaft at every oil change!

Engine & Transmission Mounts
Especially off-road, these parts take a beating! If a mount gives out, you can wind up with expensive engine or transmission damage. Transmission movement can cause the linkage to bind, resulting in improper shift patterns. At its worst, this can result in transmission damage and replacement. Broken engine mounts can allow the engine to move freely in the engine compartment, which can pull on air conditioning hoses, causing them to leak or break. It can also break other components in the engine, in extreme cases to the point of having to replace the engine.
As a courtesy, we routinely inspect your truck's engine and transmission mounts!

Drive Axles and Seals
Leakage at seals and boots can lead to axle failure. Drive axle and CV axle failure can cause loss of mobility, and, in some cases, can ruin the differential.
We will inspect your truck's axles and seals at every oil change!

Suspension
Heavy loads and wild off-road rides are a challenge to your suspension. Some truck suspensions are stronger than others, but all are subject to failure if challenged too hard. Leaf springs, coil springs and torsion bars support and cushion your ride. Ball joints and tie rods are part of the steering linkage. Failures in these parts are the most catastrophic, leading to sudden loss of control if they break.
We always check your truck's suspension to ensure your safety!

Wheel Alignment - Especially if you go off-roading!
Save those expensive tires! Prevent unnecessary wear on suspension parts. Enjoy better control - on pavement and off.
We align your truck for minimum tire wear and maximum performance!


What Our Customers Are Saying

I've worked on my vehicles my whole life if I didn't know how to do it, I'd learn....simply because I didn't trust auto mechanic shops. So it wasn't easy taking my truck into a shop. Sometimes you just have to because you can't figure out what the dang issue is. I found Gary's while researching, the shop had great reviews and it was super close too... so I gave them a shot. Stopped by the shop and found a welcoming, friendly place with a beautiful Aussie Sheppard laying at the counter like a furry greeter (a real Ma and Pa shop). Gary found it to be my PCM....he took care of the issue and went above and beyond regarding customer service, he even assisted with me getting my truck back while my wife was at work. My truck runs better than ever and I will not hesitate bringing any of my vehicles to this shop in the future. The worlds been an ugly divisive place recently and to experience this kind of old school friendly service meant a lot! Thanks Team Gary's shop!

Gary and his crew are true pros but also stand-up human beings. I brought in my car unsure of what was wrong with it but sure I couldn't drop a ton of money on it. Gary called me during multiple steps of fixing my car to make sure the work they were going to do was okay with me! Made me feel very comfortable and not surprised when I finally got to see the total price. The work they did was excellent, quickly done, and they even compiled a list of things to watch out for and timelines for future work to be done. Also they have shop dogs. Have recommended this place to my significant other and some friends as well!

Their service is incredible, and they didn't nickel and dime me like other shops do. I am always very pleased with the way my car gets back to me, and the work he does. Recommended!

I really like this spot and can vouch for their thorough oil changes and overall review of the car - more expensive than, say, a Grease Monkey, but they do more than just oil and fluid top-offs. They came recommended by a neighbor and I've been pleased with the service and attention to detail. I had a minor issue that Gary fixed and didn't charge us for. It's hard to know who to trust when it comes to mechanics, so always go with a referral from someone you trust.
