from what I understand its just a matter of putting metal shims on the rear axle and thats how you adjust the angle.. dont know how in depth the process actually is.. Im lucky my brother is a mechanic and has the lift and all the tools to help me with all my issues

 

Are you sure it's the rear of the truck? My 04 2500 has a solid front axle but I think (not sure about an 03) the 1500 uses a CV front axle? It will give a shake in the drive train if it's wore out.

 

I get nothing in the wheel only in the feet and seat that's why I have concentrated my efforts on the rear. How can you tell if the CVs are worn out? And yes they are CVs on my 03 1500. I do get an obvious squeak front right in the AM. Don't know.

Thanks Flexkid

 

OK, perhaps I was over-thinking the CV axle. However, I had a Suburban that had a noise in the floor and we spent a month looking in the rear when it turned out to be a front yoke. Different scenario but something to think about.

OK, a shake?? A shake is cause by something off balance. Did you loose a balance weight off your drive shaft? It has to be something simple because it lasted 50,000 miles without a major mishap.

 

That is what I keep thinking. Nothing just flat out breaks. I changed drive shafts with no difference so I don't think it has anything to do with the shaft itself. Another thing is it doesn't seem to be as bad in cold weather, I don't know if that means anything at all.

 

Perhaps because the oil in your transfer case is thicker due to the cold? Did you ever think to look there?

 

I haven't thought anything about that because it seemed to be speed oriented. I wouldn't know what I was looking for as far as the transfer case goes. It shifts into and out of 4 wheel drive smooth and easy when ever I do use it. If you have some clues as to what could be an issue there please pass them on.

Thanks again
