I wanted to wait to write this review until my differential was through its break in period. Now it is over and I have to say that Ty did an amazing job. I brought my 2002 BMW M3 to Ty for a gear ratio upgrade. We changed the gearing on my car from a 3.64 to 3.91. I supplied the ring and pinion along with various seals and bearings I needed. Ty was professional and friendly through the entire process. he was very patient with my several calls in the weeks before I decided to pull the trigger, and his communication during the process was top notch.
He called me to let me know that my diff had a leak and he wanted to let me know that it needed new seals and wanted my permission to order new ones. Thankfully I knew ahead of time and they were waiting in the trunk. He took great care of my car and managed to set the backlash perfectly. there was a brief scare when it turned out I may need some shims that I did not have and Ty was prepared to go to some friends in the business to find the parts. We got lucky and he was able to swap shims left to right and the backlash was set perfectly.
The process took two days and through the whole thing Ty was professional, friendly, and very appreciative of the business. He has a ton of experience with differentials and I was happy to support his new business. The car feels fantastic and the differential is noise free. Ty and Bay Area Differential and Gear Garage get my full recommendation

Boy my experience with Bay Area Differential and gear garage was the best experience ever. Not only did owner Ty give great customer service he makes you feel like family. I had a gear ratio swap out done on my 2016 Mustang GT. He really made sure my car was well taken care of. He’s honest, very competitive prices, and turn around time is fast. I will be coming back and recommending to friends and family. Thanks Ty.

Being a ‘wrencher’ myself and race car driver, I can say it is difficult to find a shop that does reliable work. What is even more difficult, and what differentiates Bay Area Differential and Gear Garage, is that Ty provides not only great work, but a superior working relationship. He is extremely transparent in the work that needs to be done and what you are being charged for.
I approached this shop based on Unilocal reviews alone and was very pleased with my experience. I brought over two Nissan R180-​type differentials, one with a Clutch-​type LSD and one without. My goal was to swap the LSD to the second differential because it had superior gearing for my racing application. Unfortunately we ran into a situation where the ring gear was larger on the second differential, giving me no other option than to purchase another LSD. Ty was extremely patient and provided a ton of guidance during this time, even when we found that the side axles did not swap over directly either. He was very open to hearing my opinion — to me this is extremely important because I more than often deal with mechanics that are NOT willing to hear your opinion, assuming you are not knowledgeable. Honestly I have no time for egotistic mechanics and Ty is the absolute opposite. He was patient and allowed me to source the NLA parts I needed to get the job done.
Overall Five Stars and I will be referring all my track junkie and race car buddies to Ty in the future.

Professional, affordable, dependable Ty is a standup guy he quoted me A very good price on my axles to convert them from a 307 to 456 gear ratio I had gone to different shops I got a quotes and I got the best price from Ty and honesty he didn’t try to get me to pay for extra things like the other shops got the job done when he said he would and he went above and beyond my expectations. I highly recommend Ty he’s a PRO

I had Ty rebuild the posi in my Dodge Ram. He did a great job in a timely fashion and had me back on the road in no time.
Ty really knows his stuff and I have and will continue to recommend anybody who needs transmission and/​or differential work to him.

He’s done it again! I recently purchased matching front gears to match the rear gear ratio, and contacted Ty to schedule a time to install the front gears. This time though, I was in a bit of a time crunch. Yet it proved no problem, everything was done same day and I had my diff back in about 10 hours after dropping it off. Incredible service, no request is too tall for him.
His new location in Hayward is right off the 92, super easy to access. I will still be recommending him to anyone I know who needs differential service. Thanks again Ty!

I needed to rebuild my stock E36 BMW open differential with all new bearings and seals and also convert it to an LSD with different set of gears. The job would also require some machining to recondition the used LSD parts and to fit the new ring gear onto the carrier. I called many (probably around 10 at least) different shops and was very surprised that no one would take on the job for one reason or another so I was relieved when I called Ty and he said that he can help me as he does this kind of stuff all the time.
I was also pressed on time as I was going to a track with my car in one weeks time and Ty assured me it can be done. He was super forthcoming with information, answered all the questions I had and after I brought him all the parts, literally the next day it was all done!
He did not install the diff cover so that I could see the inside, explained what he did in detail and explained the break in procedure.
Then the following day Ty helped me with something unexpected — as I was reassembling the car I ran into a problem. I needed to install new ball joints into the rear trailing arms. The ball joints are interference fit and BMW recommends to use a special tool for the installation which I did not have. I spent a lot of time trying different ways, but the ball joint would not go in straight. After I called Ty and explained what was going on (Sunday night), he said to bring it all in. After I brought the parts in Monday morning, Ty literally spend 5 minutes per side and it was all done! I was super impressed!
I’m very grateful to Ty, without his help I would not be able to finish the car on time for track. The differential runs super smooth with no issues.
The prices were also super reasonable to say the least.
Recommend without a doubt!

Ty is by far the best mechanic that I’ve been to. He is extremely knowledgable and really takes care of his customers. I will definitely be going back to him should I ever have any more issues and I highly recommend Ty to anyone needing good work.

Ty knows his stuff. Hes new to hayward but been in the differential game for 20+ years. Got me a great deal on a new Eaton lsd differential and labor for my broken and stock silverado one. He even helped me drop off my transmission to get rebuilt. When the truck was done, he even picked me up with it since I didn’t have a ride. Went above and beyond to help a brotha out. A+++

Ty has done several differential repairs for me. He overhauled the differential in my 2009 G37. The car is supercharged and I had another shop install a Quaife limited slip differential. That shop made a lot of mistakes and caused my gear set to fail, also ruining the bearings. Ty was very clear with his communication and explained the process for me. He fixed my differential to like new condition and the results are fantastic. After this work, I also had him repair the differential in my 4runner and I referred him to a friend for plenty of other work to which I heard my friend was 100% satisfied.
