Hello all, have been reading for a while now, but got my first CTD, a 4.5 6spd 4x SRW 3500 that I got in Colo. It has 100k on the ODO and I love it. Gets great mileage compared to my old half-ton 5.2 Dodge gasser. I am a little worried about some noise from the left front, (I have put about 10k on it since I bought it), and think that it is probably the u-joint, so if anyone has a great tutorial for getting this squared away, let me know. I have already found some very useful stuff so far. Thanks for letting me share.
