93 lx v8 - Recently had an issue where noticed a belt was starting to shred. It was pretty old so figured it was time. Have gone through a couple of different belts and found that it's riding up on/against the front lip of the water pump pulley. Nothing has changed, but it looks like the PS pump might be off a bit and pulling the belt forward (towards front of car)? I see there is probably about 1/4-1/8" of play in the pump pulley/shaft which i understand is normal. Pulley doesn't wobble.
I could shim the water pump pulley out a hair as an option as well, but don't want to bandaid the issue. Also not wanting to spend money on a PS pump if i don't need to.
Looking to see if anyone had had a similar issue.
Thanks

Will check it out. Meaning it pulls in/out not side/side.

Could it be an idler pulley out alignment (worn bearing/bushing), pushing the belt out of alignment?

Had a similar issue. Was due to pulley misalignment.
