Re: CJ7 Auto slamming in gear???
Actually, mine sounds like that too. Didn't make a difference if the chains were new or already jumping sprockets. If you floor it from a stop and don't hear any racheting, you're not ready for a chain swap yet. As dave mentioned, with the low range unit, there is just a lot of slack in the driveline. I've heard that the coarse spline output shaft from the transmission can wear causing more slack. 1/4 turn doesn't sound bad to me. Everytime I shift into drive it sounds like the u-joints are going to grenade but I've got 192k miles on the original transfer case with just new chains.
Actually, the trail fix on the transfer case was with a flashlight, pocket knife, 3/8" wrench and a piece of fuel line. My vacuum shifter quit working so I took off the top cover over the shifter and manually locked the differential. Then I wedged a piece of fuel line in there to hold the shift fork over. Another time in 1999, I had to do it on the side of hwy 60 one night around Republic when it did the same thing. I didn't have the front driveshaft on so I needed it locked.
