New DII owner serpentine belt walking
Hey guys New Discovery II owner here. I have a 1999 Discovery II with 238,683 miles and Noticed my Serpentine belt had a cut on it like it was off track right on top of the psp pulley. So I replaced the belt, popped the key a few times and noticed the belt was walking towards the engine but would stop once it was riding on the edge of the pulley see pictures.
What is the cause of this???? bad pump???
If you notice the white line on the belt that is were the belt is riding up on the back of the pulley...oh sorry for the crappy resolution..lol

You have a pulley out of alignment somewhere.
The most common ones are the water pump and power steering pump.
When the bearings go bad in either one of those the shaft can slide out (or in).
I would remove the belt and start spinning pulleys and checking for play.
A bad belt tensioner could also be the culprit.

The power steering pulley might be installed backward. Try reversing it, but if it is even worse after reversing it, then the triangular flange on the end of the shaft has walked forward. It is just pressed onto the shaft. That is what happened on mine: pulley walked forward and cut one rib off the belt. Only cure was a new pump (or a used one) because the flange can't be pressed back on the shaft.
