p/s pump due for a replacement

[Fless]

Fair!

Honestly.... I'm probably getting more wound up in my head about pump differences vs. just accepting the damn thing is worn and that's the source of my issues hah. Didn't have this issue when I picked 'er up at 115k. It's just due for a new one!!


One thing I'm not certain about, however, is which pump I actually need. I'm seeing 2 potential units for my truck. AC Delco 15909832 and 88963604. Gotta be honest... I can't tell the difference between them

If I can believe the pics on RockAuto it looks like the difference might be the clocking on the pulley shaft. From what I can see they're 70 or 80° different. ...3604 looks more centered. Might be an illusion.
