Power Steering Rack & Pinion Frustration

I have little experience with the power steering system and need some help. I had my power steering pump replaced about two weeks ago and was told that pump's intake hose coming from the fluid reservoir was leaking. I took it home planning on replacing the hose before leaving for school, but simply ran out of time. After coming back to school, I took my car into a garage and asked them to simply diagnose a whine around the serpentine belt and give me an estimate on replacing the leaking hose.
After leaving the car there for a few hours, I came back to find power steering fluid pouring out from each boot of the power steering rack and went in to be told that the supercharger was shot, and the power steering rack was bad, and it was the "power steering rack flinging fluid around which caused the hose coming from the reservoir to appear as though it was leaking." The man at the counter told me that the only way for them to check the seals in my rack was to slit small holes in each boot. Does this sound right? Because I do not think it does. I am frustrated because my car which once held power steering fluid and was drivable, is now parked and rendered unusable until I scrape up the money to get a new rack.

What are your opinions?

If the internal seals on the ps steering rack leak the gaiter rubber boots can fill with power steering fluid and the level slowly drops in the reservoir. Most mechanics would release the clips on the rubber boots to check for leaks rather than slit them but perhaps the clips were seized in position.....

Was it the same garage who did the power steering pump?
Did the old pump run for a long time and get hot when it went faulty as the overheated fluid can damage the rubber seals inside the rack causing the problem you have.

The supercharger problem is unrelated but what is the fault and did you notice anything when driving before......also what is the current mileage, superchargers are normally good for around 100-120,000 miles before replacement is required.

Do you think they should have asked me before slitting the boots? All I simply asked of them was to give me an estimate on the hose. I hope they were not trying to put me into a predicament where I would be forced into having them fix it.

This was a different garage. I live in VA, and go to school in TN. The garage that replaced the pump was in DC, this garage is here in TN. I bought the car with the pump whining, being aware that I would need to have it fixed - thankfully I didn't have to pay for it, as it was still under warranty.

The car just turned over 100k very recently. It wasn't but a couple of weeks ago when I started to hear the whining in the motor. I was told that the bearings that are inside of the supercharger are shot, and needs replaced. The water pump is okay, and I have not noticed a major difference in the supercharger's response. here is a link to the noise:

Yes I think they should have asked your permission before slitting them and given reason why they could not release the clamps on the rubber rack gaiter boots to investigate for fluid inside?

Perhaps they should fit new boots, top up fluid and let you try elsewhere....

Here is a link how to do an oil service on the supercharger but it may be too late for yours and time to get new or reconditioned replacement if the bearings are noisy.

I have decided to move forward and install a new power steering rack. While I have the subframe down, what else should I replace? I know that my lower control arm bushing needs replaced. Is there anything else you guys recommend?
