Mazda Miata NA/NB steering rack depower service
This is a service to depower your 1990-2005 Mazda Miata steering rack. This is the work only and you supply the rack.
Price includes: rack disassembly, removal of dividing hydraulic seal on the "rack" portion of the rack, TIG brazing of the pinion, welding of all exterior hydraulic ports, and reassembly of the rack.
We prefer to TIG braze the pinion shaft instead of welding it. We do this to limit the amount of heat that is put into the shaft. This shaft operates in a very fatigue heavy environment and TIG brazing helps preserve the OEM metallurgy of the part which would otherwise be disrupted by a weld. TIG brazing also keeps the shaft at a much lower temperature which lessens the disruption to the OEM heat treatment of the part.
On reassembly, all internal components are generously greased and reassembled per Mazda instructions.
Disclaimer: the depowered rack is not for road use! In fact, it is not intended to be installed into a car and should only be used for a display on a shelf.
