Power Steering Flush
Most cars with power steering have a rack and pinion style set-up. This is a pressurized system that allows you to steer easier than the old manual type steering systems, especially at lower speeds. Over time this fluid can become dirty and the seals can start to leak. If you replace the fluid there is seal conditioners in the fluid than can slow the rate at which the seals deteriorate and prolong the life of the system.
