Just took my RTV back to the dealer for slack in the front driveshaft which makes an extemely loud rattle when idling. When put in 4 wheel drive it stops. I know of one other forum member who had nightmares with his dealer attempting to fix this problem with no success. He replaced both yokes, driveshaft, carrier bearings, and now thinks that they will have to go into the tranny. I was just curious if anyone else was having this problem and what you did for the cure.
