Went 4x4ing this weekend and my 4 wheel drive Quit. I was hearing a clanking from the transfer case area. I dropped the transfer case skid and there was grease all around where it meets the front drive shaft. There is a boot that is there that is not sealed and the drive shaft is moving around. I can clean it up and get some new grease behind the boot and get the boot back in place but it wont stay. What did I loose or how do I get it back together? What hold the boot in the t-case? Is this something I can do? Please help and thanks in advice for any replies. I just want to get this fixed so I can use my 4-wheel drive.
