My power steering pump began screeching overnight. The day before it was working fine, the next morning it was screeching. Now it completely went out. Apparently while breaking a line broke, causing a puddle of power steering fluid on the ground. I found one at a used part junk yard for $50 bucks. Apparently the guy didn't know anything about Land Rover parts value and was comparing it to an american made model. Hopefully this will correct the issue.

Next, the air ride motor constantly runs. I think the balloons leak. If I disconnect the motor with the rear end completely bottom out, or does it have a stopping point where it sits. Since I bought the car it has sat lower than normal. SO will there be any difference?

 

Did you check your power steering fluid level as soon as it starting making noise or did you drive it until it broke?

Personally, I would replace the SLS with coil springs.
