Forum,
I recently changed the power steering pump and steering box. Changed the pump as it was squeeling at either end of the turn, and put in a 12:1 Lares 807 gearbox. I'm running March aluminum pulleys.
Following the installation I bled the system and it felt tight and sounded much quieter- no squeeling. My son drove it the next day, all looked good, but when he pulled into the garage the squeeling was back. I have bled the car several times ( using the vacuum method ) and each time the sound goes away, then comes back.
So here are my questions:
There are no leaks in the system- could air be pulled in somehow?
Is there an optimal pulley size for our rides- and does it change if the ratio changes?
I've read that pumps should match the gearbox - any ready references out there, or do I need to call Redhat or someone of that ilk?
And finally, any other ideas that you guys have?
As always, thanks for the help!
