Are you turning "locking" your steering wheel ALL the way to 1 side when you hear that noise?
Does it happen when u turn left?

Before you go changing anything, be sure of your diagnosis. Your diagnostic method does not sound foolproof. If the rubber CV boots are torn open and all greasy, then yes the CV joints are your noise. if the boots are not torn, then you need to keep looking.

Thats a big rock chief considering the MDX has decent clearance. ANyway, too bad i cant hear it in person because i know several rubbing sounds, one rubbing sound is from the wheel hitting the wheel well, rubbing sound from the axle (its more of like rumbling) as well as the bearing. Jack the car up again and try to simulate the even buy turning the wheels and moving each part back and forth for play. Im sorry but online has its limitations.

I have been wracking my brain and there really is not to much to that system. If you have changed the pumps. Are you certain the lines and pump were installed correctly? Hows your rack? (I meant the steering rack hehe) Did you do the work or have someone else do it? Is there any power assist at all? Did you check the steering yoke at the end of the the steering column were it is attached at the power steering rack? This yoke is known to freeze up and make it difficult to turn the wheel and making it seem like the power steering pump is not doing its job.

When you've replaced your power steering belt did you check the condition of your power steering hose? Check out the Recall below for your vehicle

Ok, the symbol you see is simply a tire pressure warning light letting you know a tire is low. Check the air pressure, fill as needed and take it for a drive and the light should go out.

If the VSA light is on, a trouble code is stored in the vehicles ABS (anti lock brake) control unit. This code can only be accessed by a scanner. The code is vital in troubleshooting accurately. Most shops and auto parts stores will scan them for free. Sometimes only a reset procedure is needed. I would recommend having it scanned, write down the code, clear the code and test drive to see if it duplicates. If it does, send me the code and I will take it from there. If it does not, no problems.

Could be that you have bad wheel bearings.

honestly it could be a variety of things bad inner and outer tie rods, sway bar links, ball joints, control arms it could be so much but its a much needed fix as it could seriously hurt you or someone else on the road!

well the next time you have your car in the air grab the sides of your front tires n give them a shake from side to side n if there's any play that's tie rods. that's just a start but its better than replacing the whole rack tho..

could be an axel.

Based on your question it led me to believe you need to know how to install the actual hooks aside from the rubber hangers themselves because frankly they are pretty straight forward.

For the hooks: If they have rusted, you just weld a new one in place
For the hangers: you just slide it into place, some of them are secured by locks.

Now i dont mean to sound like a smart ass but i just got my exhaust system customized (civic) and all we did is weld and cut. Nothing more complicated than what i just said.

Chime in if you need more detail or clarifications.

you bend something on the front end like a tierod and knocked it out of alignment have it check and get it realigned
