Hey all. I've got a 2004 dodge 3/4 ton 4 x 4. It's had a vibration since new that starts at around 70 mph. Took it back to the dealer and they replaced the rear driveshaft and told me it was fixed. Not. I pulled the front shaft and the vibration disapeared. Took it back and they ended up robbing one off a truck in the lot as the new one they had ordered did the same thing.
Was definately better but still not as smooth as a 30some thousand dollar truck should be. They told me that was as good as they could do. So I've lived with it for 5 years. Don't do a whole lot of highway driving any way. Just made a 500 mile trek though and found it rather annoying.
Just happened to be talking to another dodge owner a while back and he told me he thought it was a pinion angle problem and Dodge had a service bullitin and shim kit to fix. Dealer knows nothing about it.
Well I took a look and the driveshaft definately isnt in line with the pinion shaft. Looks to me like I could adjust the lower control arms to rotate the diff into alignment or at least close. I guess I'm wondering how bad that would screw up my alignment. The truck has 62k on original tires with miles to go. Hate to fix my vibration issue only to chew up $200 tires. Or is there some other solution I'm overlooking. I don't believe its a balance issue as there has been at least 3 different shafts on the truck and they have all done it to some degree.
Thanks for any thoughts or input.
