1994 Q45 needs replacement Rack & Pinion

Hello,

The Infinity dealer says I need a new Rack & Pinion since power
steering fluid is leaking due to the damaged Boots. Can I just simply
replace the Boots to stop the leaking and keep dirt out? Also, if I do
decide to replace the Rack & Pinion, what other parts are needed (e.g.
Boots).

Also, I was told that I need a Wheel Alignment when I get the rack &
pinion replacement done. Is this true?

I noticed that delaer prices for a genuine Infinity Rack & Pinion is
about 4.5 to 8.6 times higher than if I where to get a remanufactured
one from the internet. What are the advantages/disadvantages of
getting a remanufactured part? Also, what does a "core" mean? Is it a
deposit that is returned when you mail in the bad part?

I am just a guy trying to save money on my car repairs.

Thanks,

I want to add something to my original post. There is something called
the Rack & Pinion Kit. What does this kit include other than the rack
and pinion? Also, what is the labor cost to get a local mechanic to do
all of this? Is there a www site that will show the mechanics labor
cost?

Thanks,
