If you're having power steering problems, the issue isn't a pump adjustment; it's likely one of the following:
* Low power steering fluid: Check the fluid level in the reservoir. If it's low, add the correct type of power steering fluid (consult your owner's manual). A low fluid level can lead to groaning, whining, or difficulty steering.
* Leaking power steering fluid: Inspect the hoses, pump, and rack and pinion for leaks. Leaks need to be repaired.
* Failing power steering pump: A failing pump will often make whining noises, especially when turning the wheel. This requires pump replacement, not adjustment.
* Failing power steering rack and pinion: Worn components in the rack and pinion can make steering difficult and may be accompanied by knocking or other noises. This requires repair or replacement.
* Air in the system: Air in the power steering system can cause spongy or ineffective steering. This sometimes requires bleeding the system, a procedure best left to someone experienced with auto repair.
* Belt issues: A slipping or worn power steering belt will reduce power assist. Inspect and replace if necessary.
In short: If you're having power steering issues, take your car to a qualified mechanic for diagnosis and repair. Trying to "adjust" the pump when it's actually failing or has another underlying problem will likely not solve the issue and could even make things worse.
