I was wandering how hard it is to replace the out put shaft? My daughter wants a dodge ram for her first vehicle. I found one for 600. the owner who is selling it says it need a new out put shaft. he also said it was making a clinking noise in the rear of the tranny. but he said it did not start doing that till he replaced the flywheel. So I am thinking he just did not put in the right fly wheel or did not install it right. Am I correct?
