I have a 99 sahara 3" Tereflex lift 33-12.50 67,000 miles. It first began at a slow speed, sharp turn, no performance issues but a weeo, weeo, noise unitl I would straighten the wheel. It has gotten much worse. Power steering fluid is normal, new rancho stabalizer. Now the noise starts when the wheel is half way cranked. Could it be the pump? Broken gears? Everything is tight. Any replies would be great.
