Overnight Differential Rebuilds Without Cutting Corners
Our story
About Pomona Gear
Pomona Gear is a differential and driveline shop built around one idea: tell customers exactly what is wrong, fix it right, and get them back on the road fast. We work on everything from lifted trucks to daily drivers, handling differential rebuilds, regears, pinion bearings, driveshafts, and U-joints.
When a job is apart, we show customers photos and video of the actual damage and the OEM parts going back in, so nobody has to take our word for it. We do not push upgrades or extra work that is not needed. If a job can go back to stock or get upgraded, we lay out the choice and let the customer decide.
We know that a bad rear end usually means someone is stuck, whether they are hauling a trailer through town or towing one home from out of state. That is why we move quickly, sometimes finishing overnight, without cutting corners on parts or workmanship.
- Same-day and overnight turnaround
- OEM replacement parts
- Photo and video proof of every repair
- Straight answers, no upselling
What customers say
“Took my 2013 Ford Raptor to Pomona Gear, couldn't be happier with the experience. Sam was very professional, got me in the same day and rebuilt my diff overnight and had me on the road in the morning! Great work, great price, and you know you're getting top notch service.”
“I took my Tacoma in for a rear differential repair and was informed that the pinion bearing and a few other components needed to be replaced. The work was completed in a timely manner and the pricing was extremely fair. Sam is very knowledgeable, honest, and clearly experienced at what he does.”
“Just as all the other reviews have stated Sam is a honest guy that gets his customers what they want and need quickly and effectively. Once my truck was apart I was faced with the choice to go back stock or go upgraded. Sam didn't push either direction. He said it's your choice, the labor is the same, so it's up to you.”
