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!

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

Clean shop and the guys here are a master of their art. Keep it up guys!

-Wayne M.

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!

-Michelle W.

I got my vehicle promptly fixed and the price was very fair. The shop is very organized and clean. He is honest and professional. Highly recommended!

-Amanda W.

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.

-Allison J.

Their prices were more than fair and their work was wonderful. I just wish I knew them earlier for my car repairs!!!

-Cynthia S.

Great prices, very friendly mechanic. Gary was really nice and informative. I highly recommend this place.


I have lived in Denver for 4 years and I have been searching for a good, independent, fair, and reliable car repair place. Alot of the auto repair shops capitalize on my ignorance in regards to cars. Gary's DID not do this. They took their time... analyzed the problem and fixed it! I will not take my cars anywhere else as long as I live in Denver. Thank you so much!

-Julie M.

Great customer service. I couldn't ask for a better experience. Car was finished in a timely manner and all details and transactions were explained thoroughly.

-Haley M.

I realized I never actually left my review here. I went through Gary to get my AC unit for my 2009 Prius fixed in Spring 2018 but can't remember the exact date. Calling to make the appointment was a quick and easy process. He was able to see my car a lot sooner than I thought he'd be able to and was able to diagnose what the problem was quickly. I was hoping just for diagnostics to get done, but it turned out he was able to diagnose the problem and fix it all in one go. It was finished the same day I took it in and it made things so easy. I was running a few minutes late to pick up my car and he even stayed late so I could get it picked up and not have to wait until the next day. I would absolutely recommend calling Gary if your car is acting up.

-Alia G.

Wonderful mom and pop repair shop! Down to earth and up front with their customers. They won't rip you off, best car repair place I've ever been to.

-Vick M.

I had a pretty serious emergency with my jeep. Gary gave me all the data that would cover the repairs, and more. He was extremely professional and fair, as well as helpful in explaining what had to be done. His prices are very reasonable, his shop friendly, and they got my jeep done in one day. I would highly recommend him to anyone who has any kind of car repair.


Went in thinking i had major problem. They could of really taken me. I walk out with a fixed car for less than 100.00 and an oil change.


I called to see if they could work on my vintage, British car and although they didn't, the rep. suggested me to a place that did. This was such a relief! I'm so grateful for their knowledge on not only what they worked on, but other mechanics in their area.


I found Gary's full service by chance off of the better business bureau's website for their rating of A+. Recently having moved across the country from Pittsburgh to Denver with my 150,000+ mile 2003 Trailblazer I found my self in need of a mechanic. After I arrived my car was still running but the ABS light was on and the check engine light was intermittantly flashing. I took the car to two other mechanics that told me the ABS computer was out and would cost $1000 dollars just to replace. I hesitated to do the work. Unexpectedly the car developed another problem and overheated. I had to make a decision fast. I had the car towed to Gary's. Not only was the very fair with his prices, fast with his service and honest he CORRECTLY DIAGNOSED THE PROBLEM AND SAVED ME NEARLY $1000 dollars. I will never go anywhere else and recommend him to everyone I meet. He is everything you look for in a mechanic, no wonder he is still in business after 25 years! Go here I promise you will be happy!

This place is a jewel that I found in Aurora. It is a family owned business and the owner inspects everything before it leaves the shop. I actually waited 3 minutes while the owner went through my vehicle to make sure it was exactly the way it should be. This is old school customer service. What a breath of fresh air.


After moving to the area almost 2 years ago, I was looking for a good independent auto shop. gary's was recommended I have found them to be competent and price competitive, and performing or recommending only work that should be done. This has been welcome after some experiences at a dealer.
