During the Vauxhall Steering Rack reconditioning process the steering rack is fully disassembled and cleaned before re-assembly with new Seal kits, O-rings and Bearings, all of which are replacements as part of the reconditioning process.
Initial Inspection and Fault Assessment
The rack is inspected for any signs of damage and the play in the rack and pinion measured. Any leaks or signs of corrosion are also noted. This enables the technician to assess the components that will need replacing and also to identify any damage that would render reconditioning impractical.
Full Disassembly and Cleaning
This stage of the reconditioning process involves the full strip down of the unit and all components are cleaned of old fluid, dirt and debris. This stage is critical as any hidden wear or scoring can be revealed by cleaning out all the contamination.
Seal and Bearing Replacement
We replace all the seals, O-rings and bearings as part of the reconditioning process. Using old worn seals as part of a cheap re-build can cause rapid failure.
Rack and Pinion Surface Checks
The rack teeth and the pinion gear are inspected for any signs of wear, pitting, flat spots, etc. If any serious wear is found to either the rack teeth or the pinion gear then these components are replaced.
Reassembly and Preload Adjustment
The steering rack is then reassembled and the pinion is checked for the correct preload. This will give the correct amount of resistance when steering, a rack that is too loose will give a vague feeling, and a rack that is too tight will make the steering heavy.
Bench Testing Before Despatch
The completed unit is then tested and pressureed to check for any leaks. The rack is then cycled through full operation to check for smooth operation.

A professionally reconditioned rack should now perform in a similar manner to a new one after having gone through all of the appropriate stages of its reconditioning process.
