I have heard the Explorer pumps are hit or miss for guys. Some people don't have any problems with running them on their Broncos and some have issues probably very similar to yours. I just recently swapped in the Explorer serpentine set-up on mine but decided to go with the Saginaw pump. I am running a 351W so had to do some other mods to that Wild Horses bracket set that ZOSO mentioned.
Prior to changing to the serpentine and Saginaw, I had a stock Bronco pump and it worked about 60% as good as my new set-up. I have 34" SuperSwamper tires and can turn the wheels with one finger with no squeel or dead spots.
You can probably buy just the bracket set from WH for $70, buy the saginaw pump and pulley for less than $100 from NAPA and make your own PS hose for $20-30. Save yourself $50 or so plus I am sure shipping would be cheaper...
