It is quite simple where bearings are concerned. With the track or drive belt removed, one can manually spin the respective components and determine which one is the culprit! A bearing in good condition will make no noise when spun, however, if a pulley refuses to spin or makes a ZZZZZZZZZZZZZZZ sound, you are on the right track! I am twice ASE certified auto tech so let me know how it goes!
Check your wheel bearings and at the same time check your brake pads.
I have changed the idler pulley here recently on my 2001 ford ranger 3.0L, I dont know how off the top of my head, but a Haynes or Chilton's manual is the absolute best moneysaver you could ever buy for that truck. It will tell you how to tear it down and put it back together. They run about 15 bucks but it will pay for itself over and over again! I hope I could help.
my ford 2001 ranger had the same thing happen to me i sent to the ford delear for repair and it was a missing fuse so check all fuses
Check the fuel pump relay
One of your pulleys is out of alignment or the bearings are going out. Sometimes if the belt is way overtightened it will jump off from metal brackets bending. The fault is the centrifugal alternator pulley.Buy a new pulley or the easier way is to fit a new alternator,the pulley is very hard to change.
yup
The crankshaft pulley is the large pulley on the lower passenger side of the engine.

check tensioner pulley and idler pulley if equipped.
Check with your local auto parts store. A new idler pulley is an inexpensive item.
how to replace water pump on 2001 ford ranger
There are a couple of reasons why a 2001 Audi would make humming noises from the back while it is being driven. The first thing to check is the tires. If the tires are fine, check the wheel bearings.
