Why is the motor roaring ? is it rubing on housing or a bearing ?

It may not be you motor, but the sound of some item caught in the impellar, which is the part that causes suction. It is usually located in the upper housing, and can be accessed fairly easily. Unscrew any visible screws,(usually phillips type) and carefully lift housing off. This should expose the impellar. If debris is present, remove it.
But also check for possibly broken fins on the impellar itself. Sometimes items like coins, or nails etc, will get picked up accidentally, then spin around in the impellar housing, only to break a fin or two trying to move on. If this has happened, replace the impellar.

My pump squeels loudly. I think it's a bearing that I can't get to because I am having trouble getting the impellar off.

If the impeller has never been removed it may not come off. Impellers unthread counter clockwise off the shaft of the impeller by putting a big flat head screw driver on the motor end of shaft.
If they have been on there for years they can become rusted onto the threads of the motor shaft.
At that point if it will not unthread then you will need to break it off.

I have a Pentair 2.0 pump that I am trying to remove from the impellar. The shaft turns allowing me to turn the pump part itself but I can not pull it loose from the rest of the housing. How exactly do I...

The impeller is threaded onto the motor shaft. On 2hp motors and above, there is usually a screw with reverse threads to help secure impeller to shaft. To remove impeller, first remove screw(reverse threads) Next, remove back cover off motor. The shaft either has a slot for a screwdriver or flats for a wrench. Hold shaft and unscrew impeller.

I'm not sure I understand your question.
To get the impellar off of the shaft, leave the motor bolts on.
Open the back end of the motor, there should be a slot in the motor shaft. Use a screwdriver to hold the shaft from rotating and grab the impellar and rotate it counterclockwise to unscrew it.
It sounds easy, but the impellar is probably somewhat corroded on.

Jandy jhp .75 hums when you turn it on does not pump

It sounds as if motor is spinning and pump is free so the impellar must not be attached to the motor shaft. There is a set screw on the impellar to hold it to shaft or the pump impellar could be cracked. Only way to tell is take the impellar housing off.

Pump disassembly

I removed the impeller on my DW761UQB. The instructions were molded into the plastic pump housing. This is how I DID MINE: Remove motor mount screws. Remove the chopper screw (screw only goes into impeller, not motor shaft). Remove chopper and rotate/remove strainer. Place socket or wrench on impeller tip and place another wrench on rear of motor's plastic fan. Unscrew fan from impeller shaft ( threads are LEFT handed, turn CW). Once fan is 'backed off' of the impeller, CAREFULLY pry the motor/fan from pump housing (impeller is attached to motor shaft via splines). Don't crack the delicate plastic pump housing. Mine was stuck, but separated with moderate force. Now remove the impeller/seals from the pump housing. This worked for MY above mentioned model, I don't know what other models it applies to. I am not a pro.
