The belt has shifted to the left, how do I move it back over? And it sounds louder than normal.

Sounds like maybe a bearing is defective and letting the drive drum move around and misalign the belt.

Rotate tires to see if noise moves.

Sounds like either a bad tire or wheel bearing. Check you tires for rough spots or high/low spots and replace if belts are broken. This is a raised area on the tire that will run diagonally across your tire. If tires look OK try moving the front tonthe back and see if the noise moves. To check for a front wheel bearing drive about 50 kms per hour and slowly turn the wheels left and right. If the noise gets worse or louder you need a bearing. For the back younhave to raise the rear and pin the wheels by hand and listen for a roar.

You might be able to place the truck's rear end on Jack stands. Then put in gear with the brake off. So the rear wheels can spin, while some walks around the truck to help isolate the sound. Once you have a closer area to listen to isolated. A trick to isolate more is to use some thing like a wooden rod and place it on ect. the engine on one end and the other end to your ear. Move it around til the sound is the loudest. If you have a stick shift you can use the gear shift to listen to the trans. while some else is driving as well.

Drive until the sound appears and move the steering wheel left and right a little.Can you change the sound at all?If so it's wheel bearing time.

means your transmission is slipping . that would be your over drive and 3rd and 4 th shift solenoid

generally means a power steering pump issue. Go to a car parts store website and find one for your car, then find the thing under the hood, mounted to the engine and being spun by the belt, which looks just like it. often there is a cap with a dipstick and you can check the steering fluid level. if the level is way down you may have a leaking hose or other component.

about 2000 there was a shift away from the old style fluid pumps to electronic systems so do not be stunned if there is no such thing as a power steering pump for your car. but if the noise gets louder by moving the steering wheel, you still need to look at whatever is boosting the steering wheel motion to steer the car.

PROBLEM: The walking belt is off-center or slips when walked on SOLUTION: a. If the walking belt has shifted to the left, Start unit @ 1.0 mph using the hex key, turn the left idler roller bolt clockwise 1/2 of a turn to move belt to the right. Be careful not to overtighten the walking belt. If the walking belt has shifted to the right, turn the left idler roller bolt counterclockwise or clock wise 1/2 of a turn depends on the tension that will be on the belt take your time and walk on it to feel the belt underneath you Repeat until the walking belt is centered.

Possibly the roller, I would have to hear it to be sure, but if it sounds like a clunking noise, it is probably a roller, if it is more of a high pitched whine, or a sound like a penny in a vaccum you probably have something stuck in your blower.

There's a hex screw at the back of the deck, just to the left of the belt. Turning this screw one way or the other will change the angle of the roller. If the roller isn't at the correct angle, the belt moves over either to the left or the right.
