Differential welding service Mazda Miata

This is a differential we welded for a local drifter. The car is a Mazda Miata. Stock open differential would not work at all and a Torsen differential was too unpredictable for the customer’s liking. This open differential was supplied for welding services. Our differential welding service is different from most people. While most think it is acceptable to remove the back cover, “degrease” the gears with brake cleaner, and proceed with welding, we do not think this is a reliable solution. Our differential welding service involves complete disassembly of the differential, washing and inspecting of components, and reassembly. We check gear backlash before disassembly and afterwards. If it is our of spec, we fix this as well.

We offer this type of differential welding service for $150.
