I have a Dodge 2002 SLT Truck with a 4.7 engine and it whines when I accelerate. I took the serpintine belt off and it still whines when I rev the motor. Can anyone help?

route the belt over the big pulley first as you route to the rest of the pulleys the last one should be to the tension pulley guide the belt half way on the tension pully pull the belt with your hand as if the belt is turning with engine. make sure belts in the groves of each pulley.

Did this on my 2002 Stratus 2.4L. I agree with other poster, you do have to remove the passenger tire and wheel wall to do it, but the tensioner travels clockwise.
Note: I offer this solely as a description of how I accomplished the task on my vehicle. It should not be taken as me advising anyone else in any way on how or whether they manage to repair their own vehicles.

1) Engaged parking brake, loosened lugs on passenger front tire.
2) Jacked-up and placed jack-stand.
3) Removed piece of black under-carriage which surrounds the oil filter and attaches to front bumper. There are at least 10 plastic push-pins to remove and I managed to destroy half of them in the process.
4) Positoned belt over lower pulleys and tensioner (as best as possible) then used a bungee to hold the top end of belt up while I worked under the car.
5) Used a 3/8 ratchet and inserted into square hole attached to the tensioner, disengaged the tensioner (moves clockwise) then used a brace to keep the ratchet handle in that position.
6) From top, removed bungee and finished placing belt over alternator, checked the position of entire belt, reengaged the tensioner, and replaced wall and wheel.

There sre usually two things that make a whining noise.The power steering pump/rack and pinion or the transmission's pump.My guess is the tranny pump
