I'm trying to change the clutch in my '92 1 ton tow rig. It looks to me like the crossmember for the torsions bars needs to come out to give room for the transfer case. No problem. I have all the bolts out and all of the tension off of the bars. I've been banging back on the crossmember with an 8 pound sledge. Am I missing a keeper or something? Or am I just fighting rust?
