The symptoms of rack and pinion leak are fairly simple to discover. First, if you look at the steering column and tie-rod arms and if you see any signs of leakage you know you probably have a rack-and-pinion leak. You can also look under your vehicle for grayish leakage on the ground. This indicates your steering system is leaking. Another indication is that the steering load will become heavier, possibly in one direction more than another. Finally, you'll notice that the crispness that you have come to expect from your steering system will likely be gone. Instead, the steering will feel more like a recirculating ball steering system and there will be more play in the steering wheel.
