I’ve had two shops tell me that I should replace my rack and pinion system because there’s a leak. Also had a shop really emphasize that my lower ball joints needed to be replaced. I usually do most of my work with a lower cost mechanic who doesn’t try to oversell repairs. Since the power steering fluid is a slow leak and the car is running great with no crunching sounds on turns or bumps he thought I could keep driving as is. The car has 220,000 miles is a 2005 V6 AWD. I recently replaced all four struts with KYB struts and boots and replaced the sway bar links at that time. Are there dangers of driving a car with worn rack and pinion and worn lower ball joints until they start making noise or making a noticeable difference with steering?
