THE PROBLEM:
The PS steering pump began whining after upgrading to the 12:1 higher ratio gearbox from powersteering.com
We decided the pump was probably original and needed rebuilt, so we sent it off to powersteering.com too.
We just installed the rebuilt Pump, bled it while jacked up and engine off (stop-to-stop about 10x) then again with engine running. Topped off the reservoir, and it is still whining. No difference from rebuild.
ADDITIONAL INFO:
The gearbox was rebuilt as part of a complete front suspension replacement. All new Moog front suspension. Might try some PS fluid additive.
Any ideas, folks?
Could the new gearbox ratio be stressing the stock power steering system?
Would upgrading/converting to a later-model pump give it the power it needs? Any help would be greatly appreciated.
Thanks,
JB
