is this a common place of failure on these trucks.

my tensioner seems to jumping around a bit and seems to have a slight bearing knock to it. (word of advice careful when using a stethascope that engine is freaking loud!!!)

anyways does the tensioner pulley come as a seperate piece? cost?

Yes, it was about 20 bucks at Advance Auto. Took me about 30 minutes to swap including a few beverage drinks.

Pully is avaliable as individual part. However, suggest purchase entire tesnioner assy. They wear where they pivot and allow miss alignment of belt and failure. Pulley $20 or so at Auto Zone, Advance, ect. Dayton brand tensioner about 65 from Auto Zone, 69 from advance, 150 from others. Belt for 18 at Auto Zone. Supposedlly higher quality belt for up to 70 at other places. Take your pick. JMO

With that "loud" engine it can be hard to tell for sure where the sound is comming from. The 'fan support hub' bearing can cause the same sound. The bearing on mine went bad and it destroyed the the fan, fan-clutch, and the radiator! Expensive!! (also needed new fan bearing)

Looking back I rember hearing a strange "bad bearing" kinda sound near the front of the engine. Wish I'd have found what was causing the sound sooner!

i can physically see the bearing jumping around in transition with the bearing sound.

soo chances are that is the culprate. will keep you guys updated should have some parts from dodge tommorow.

Oh how I wish we had AAP in Canada, all we have is Canadian tire which is 150% over priced and its little parts house that it opened part source which is 124% over priced..

well i found a ac delco pulley for 30 bucks my cost through my work.

now my question is. i noticed on the factory pulley the belt runs on the flat side.

the new pulley i got is ribbed. does that make a difference or did they give me the wrong one?

Busboy

You need a "back idler" pulley the one you got is just an "idler" pulley. I hear you about the parts source and Canadian Tire prices but we don't have many options.

dj_souvlaki

what do you mean by black idler pulley?

i told the parts guy tensioner pulley and that is the only one that came up in his system.

i'll go to napa tommorow and compare it with one of theirs

The tensioner normally jumps around some with engine running. Pulleys are not perfectlly round so you get some pulsating of tensioner. Release tension on belt and turn pulley by hand. You can generally feel a bad bearing.
Yes, This tensioner must be flat as back(non grooved) side of belt rides against it. Remember I suggested replace the assy. as they are a wear item.

I'm not sure but maybe the ribbed pulley is for non A/C trucks.

Busboy

A back idler means the "back" of the belt rides on the pulley and not the inside. As for Non AC trucks ALL the pulleys are the same except the AC of course has a compressor, the difference is you just route the belt differently.

i mis read and saw black idler pulley lol.

and as far as the whole assembly goes they want 350 my cost for it.
