Squeaky pulley?

No, you need one 16603-0P030, aka #1 pulley, and two 16604-0P011, aka #2 pulley. #1 has an extra wide bearing and goes next to the AC. The smaller bearing pulleys go by the alternator and PS.

For the V6. Not up to date on the 4 cyl.

 

Appreciate it.. I have the V6

 

The tensioner bearing is really easy to replace as shown in that linked thread. I bought new OEM idlers, but did the bearing only on the tensioner pulley as my belt tension appeared to be just fine. Recommend going that route over buying an aftermarket pulley, due to quality and/or fitment issues.

 

Good to know. I wont buy aftermart parts for that truck..
