So does anyone know if you can buy just the pulley or bearing kit for our trucks or do I have to buy the whole idler arm assembly?? Please let me know cuz my truck is squealing like a baby pig who hates to be held. Oh and if anyone has just replaced the bearings do you still have a part # and where you got it?? I have a press.

 

Whole unit. $65 or so. A dayco part, one 14mm bolt IIRC.

 

you can buy the pulley itself but i recommend the entire idler assembly. mine started squeaking when cold but would quit when warm. my tensioner (idler) was twitching back and forth about a 1/2". replaced the tensioner with a new one which doesn't even move if it even moves at all.

 

try a case dealership theirs are still day-co metal pulleys the CUMMINS one I bought from Cummins is plastic wheel
