Had to get towed to AZ Differential Specialists with serious rear axle issues on Chevy 1 ton RV. Started work soon after we arrived to diagnose problem. Had new axles in stock and they worked extra hard at finding all parts required. Very knowledgeable and fair. Excellent work. Many thanks - we highly recommend this shop.

These guys go over and beyond, they will help you out even if they don’t have time. David is the man, he takes his time to help with patience and no attitude to give you help on the phone and in person. Great prices great labor. Recommend them to anybody. They have s a great crew

The guys at AZ Differential Specialists are top notch. This is the 3rd Jeep I have had them do gears on. I wont go anywhere else. They are always on time on budget and my parts come back cleaner than I dropped them off. Thanks again for the great work.

I own a 2011 V6 Mustang optioned with the Performance Package, the differential has been an issue for quite awhile. Rebuilt by a high priced shop twice! A friend recommended AZ differential. I’m thankful and grateful for them. I highly recommend them.

I had my CJ7 towed in after I had rear axle issues and wasn't able to drive it (back to CO). I'm so glad I brought my jeep here. I had to communicate strictly over the phone from CO and Bubba was awesome! He and the shop were honest and did

Had my 05 Ram in there to fix my differential. Took it in the morning, had it back the next afternoon where others wanted it for a few days. If you want excellent service with a professional staff look no further. To top it off was quoted a

For many months we'd been having strange noises coming from the rear end of our E 150 van. I asked mechanics at a couple different shops to find the problem and fix it. I asked if it could be the differential, and they said it still had oil

This is a great place for all your differential needs! And more!! Great honest guys helped me get my Lifted Titan Back on the road! At an amazingly affordable price! These guys are very knowledgeable and are trustworthy.. bring your vehicle

They took me without any appointment. I went with a drive with Jose. He came back and crawled under the car and diagnosed it as a shock absorber problem. It’s a very honest company that cares about its customers. They only do differentials.

Called them earlier in the week to see about and inspection (had fluid coming from the differential housing) and said to come on down. Went down and one of the techs raised the car to have a look and found the issue and was able to fix in a

I brought my van to them to have the rear end rebuilt with all new bearings and seals. They got my van done in a day and also found out that the carrier was bad.They had another one and replaced it at no additional charge. They did awesome

Update your hours on Google so that people don't waste their time driving here. In response to owner: nobody else seems to have issues with updating their holiday hours yet you blame google. Leaving a piece of cardboard on your door saying

Az Differential did and outstanding job on my 1964 Impala SS rear differential. Shop staff broke down rear differential, cut and narrowed differential to fit my vehicle better with rear skirts. During disassembly I was able to powder coat

Great folks to deal with and far more reasonable than a shop near me on the East side. They were extremely quick and very willing to help with a minor issue that turned out to be no biggie. Had my 2014 Ram 2500 swapped from 3.42 to 4.10.

Dave and Jose are hands down the most professional and down to earth mechanics. The rear end went out on our truck and they said it would be a couple of days before it got fixed because they were really busy. They Diagnosed and fixed the

Had my truck regeared on 9/12/2023. After 500 miles truck started making noise. They told me to bring it back for them to diagnose. Dropped it off on 11/14/2023 and they said a bearing failed and they replaced. Truck started making noise

Was time for the rear end on my truck to be rebuilt. I also work on vehicles and knew what it needed but don't really have the right environment for the job. Found out about AZ Differential through word of mouth. They are a professional

What an amazing experience I had with AZ differential specialists! I took my truck in to get a quote for some work and they gave me a price that was reasonable and affordable. When I took it back to get it worked on they said they would

These guys are the best! We were traveling from Arkansas to California towing a travel trailer and when we got to Phoenix the truck started making a loud noise. We found this shop on the internet and took a chance. They got us right in,

As far as I'm concerned, this is the only place I will come to have work done on differential. I recommend this shop for all your differential needs, don't waste your money and time going anywhere else. My truck now rides perfect, other

These guys are great! Friendly, knowledgeable, honest, and extremely fair.. Heard a whirring noise that I thought was coming from the rear differential.. Same day they took me in to test drive and diagnose.. He told me everything looked

I was recommended this shop from my diesel shop. David and Jose are the best in the business. Don't even waste your time and money with other shops (especially dealerships). This is literally all they do and they are really good at it.

Great crew there. Bubba was upfront with the prices and work being done. It was a quick turn around and everyone I dealt with was great. I had a cracked housing and they were able to find a new one, rebuild the thing and get me back on

Awesome business. Excellent communication, clear and concise estimate with realistic expectations. The work was done correctly the 1st time and ahead of schedule. Sure I could have done it my self cheaper but it would have been the 2nd

I took these guys a set of premium Yukon gear set. When I picked up my rear end. It was not the gears that I took them very dishonest very dishonest. The premium Yukon gears have a black coating on the edge of the ring gear all the way

If you are looking for this type of work on your vehicle look no further this is the place. They know what they're doing and they let me bring my own brand new parts. They performed my gear upgrade, rebuilt my knuckle installed harder

First off, these guys are excellent at what they do and I’ve been told by many people who are more mechanically inclined that they are one of the best in the state for differentials. I took my mustang gt in 6+ months ago and got some

Best experience ever!!! These guys are the best shop experience I have ever had. Went in with the intention of getting the price and coming back when they are open schedule. The owner said he could do it now and honestly quoted me a

I called on 12/2 to setup an appointment to get 4.56 gears and a Detroit Truetrac locker installed. They said bring in on in the next morning and they will get it done within a couple of days. I arrived at about 7:30AM and they were

If you need axle service, this is the place to go ,hands down! I took a 82 K5 Blazer in to have both axles re geared. These guys did a fantastic job in record time and I couldn't be happier with the results. Bubba, Jose and everyone

These guys do fantastic work. I could not be happier with their install of Nitro 5.29s on my Tacoma, the truck drives great and the gears are absolutely silent. I wouldn’t hesitate to recommend this shop to anybody else!

These guys always get it done fast and fair for me. Had some honesty and quality issues with another shop that has a similar name. Make sure you take it to David and the guys at AZ differential SPECIALISTS.

Great crew with David and Henry. Had my 2017 Ram 3500 dually 4x4 in for a gear ratio swap from 3.73 to 4.10's. Great price! In and out in less than a day! All done perfectly!!! Highly recommend these guys!

Great group of guys. Lots of experience. Didn't try to BS me at all. Best prices with the best warranty in the valley! Put 4.10 gears in my truck after I put 33's on... bow it drives like it should!!

I tried installing 3.73 gears in my mustang myself and it wasn’t as easy as I thought it would be. My gears ended up whining from bad wear pattern. David and everyone at az differential specialist

Henry has the best shop!...honest, reasonable, respectful and gets your car back on the road! I have depended on this business for years with several cars...always a great experience!

After taking my third gen 4Runner to two prior mechanics and wasting money, AZ Differential specialist was able to stop my axle from leaking. Should have gone to them the first time!

I took my car here because my rear-end was making noise. The work was done and fast. Noise was fixed. But when it came to ask question they didn't know nothing and had nothing to

Highly recommend this place for any differential needs! I went from 3.55 gears to 4.11’s and the truck runs and pulls great! Great guys with great price and fast turn around time!

Great people. Always get the best service from David and Henry. Shop may not look newer, but they know their stuff and can repair or modify any rearend. You won't be disappointed.

I don't like leaving bad reviews but I contacted you guys because I was driving down from Las Vegas and our local shops were too busy to get the work I wanted done completed.

Going A-B on the strip or the street? Need to gear up or down.. Trust that race car with these cats. They handle business quick and really dial you in. BIG Thanks boys!

Had an axle leak that another shop screwed up and didn’t stop the leak. These guys took care of me same day. Will definitely come back for any service they offer.

Had the gear ratio changed in my nova and these guys did an awesome job. Took care of my nova and finished quickly. Great experience. Thanks again to the team.

Fast and reasonably priced, great customer service. Jose serviced the Diff and changed the leaky pinion seal in about 15 minute's.I was outta there. TY

The service provided on my Ford Mustang was superior. Dropped my car off in the morning by appiontment picked up in the same day in the after noon.

Awesome shop. Highly recommend. They go above and beyond. Did my gears as quoted and even quicker than estimated. Wouldn't go anywhere else

(2003 Dodge Ram 1500) This was my first time going here to have some work done. Henry knew what was

Reasonable price for the labor involved. Owner or manager seemed straight forward honest.

Good work, fair price, fast turnaround.
