They replaced the rack and pinion for my 2000 Mercury Sable. It took a little longer than expected (I believe due to weather delays). When the repair was completed, I noticed an oddity. The car was making squealing/grindy noises when the wheel was turned. The mechanics said nothing was wrong (what??). I took the car to my grandfather, a retired mechanic of his entire life. He told me the steering fluid had not settled through the new steering system, and the air pockets needed to be worked out to be safe. Furthermore, the mechanics, before ever turning my car on, should have manually turned the steering wheel to work the air pockets out of the system to avoid potentially damaging the system. Thankfully, the squealing/grinding noises was the system demanding the air pockets be gone, and after a day of careful driving the pockets worked themselves out and my car's steering is perfect. I wish Expertec would have finished the job, but for the most part did the job excellently.
