???UNUSUAL NOISE???
When i am driving from 30mph & up i have a noise that sounds like i am dragging a chain under my truck i have replaced both front hubs (they were bad anyway) and replaced the rear driveshaft u-joints. this noise does sound like it is coming from the front of my truck both the front diff and transfer case have had the fluids changed and were full before as they are now as well. If you have had this noise or have any suggestions please let me know! It is a 2002 ram 1500 QC 6" procomp lift with 35x12.50x18's.

RE: UNUSUAL NOISE
On my 05' 1500 It sounds like a ratteling sound (chain dragging as you described)coming from the passenger side area about mid cab. it only does it when lightly accelerating from 45mph-50mph all other times it can not be heard. Its been doing that for about a year and a half, and I still cant figure out where its coming from.

RE: UNUSUAL NOISE
it cant be the tranny it was doin it when i got the truck and the stealership i mean dealership has rebuilt the tranny twice due to their own mess up's. It just seems to me that it is getting worse and the front driveshaft u-joint hasnt been replaced but i have never heard of a u-joint making this kind of noise!

RE: UNUSUAL NOISE
i am runnig either 89 or 91 octane but mine was doing when i bought it and i no longer have a tuner or upgraded pcm i had a fully modified pcm when i was running my supercharger. With that pcm it would spark knock even with 93 octane so i had to blen 93 and 110 to get about 102 octane out of it. but this is a constant noise and it doesn't seem to be coming from the front diff either that is why i am suspecting the front u-joint it is also the only thing i haven replaced except for rebuilt transfer case and new front diff!! It is definately starting to drive me crazy!!! And it seems that it is progressively getting worse.
