alright guys

i have a 10 dodge ram 2500 6.7 cummins 4x4


ive had a squeal coming from the engine compartment for a while now

ive checked all pullies and all seem good

ive put on 2 new belts

changed power steering, tensioner, and idler


still the mother f'er squeaks


now my question is.... when i spin the alterantor pulley then grab it to stop, something inside keep on spinning and i can pull out my pulley about and 1/8 of an inch


who can give me knowledge on that

 

Did they put the same alternator in the Cummins as the Caravan? If they did, it's got some sort of one way clutch or some BS in there that'll do that.

Something like that.

 

i think so

i replaced the alternator and still squeals like mo'fo'

 

Hmm. Any change with turning AC on or off?

 

i believe i found the issue


i compared the power steering pump i had installed to my old one and noticed my pulley on the current pump wasnt on the shaft as deep as my old one.

so i believe that is causing my belt to slip forward on the fan pulley and thus causing a squeal.


so im gonna press my pulley in more and hopefully fixes it

 

so i finally fixed that darn squeal


i cleaned all my pullies, they had some nasty stuff on them from belt dressing and soap and wd40 and all kinds of crap

i bought a brand spanking new tensioner(gates), it looked different from my stock temsioner, its bigger and pully is metal instead of plastic, had heck putting on my belt from the tension on this pulley...

the squeal is gone my friends, praise the lord for that

 

thanks for the update....

 

I have found that squealing is almost always something to do with the belt and/or their alignment. Glad you fixed it!
