Our power steering gearbox rebuild service start at $390. That includes 3.5 hours of labor, new balls for reballing the piston and worm gear and all new soft parts(seals, o-ring, gaskets). Once your box is disassembled, inspected and parts are Magnafluxed, we can then determine if any hard parts need replacing. If they do, you will receive a call with any additional costs before service is completed. Our power steering pump rebuild service starts at $160. That includes 1.5 hours of labor and all new soft parts (o-rings and seals). The same as with a gearbox rebuild, if any hardparts are damaged or worn beyond service limits, you will receive a call with any additional costs before service is completed.
