We've been using Bear Frame & Wheel in Glendora for forever. For the company trucks they've done alignment, front end repairs, & brakes. On my own stuff they've done alignment. We've always been happy with their work.
I have heard they have the equipment to bend solid I beam axles, but haven't tried them on that. I'll probably take the 2 axle trailer in at some point.
