Please HELP halfshaft questions

[ballizticbucket]

My 92 b2600 4x4 has issues. When i stick it in 4lo or 4hi it clanks and clunks so I grabbed the front D. Line and shook it, and I got no play so I grabbed the P.Side halfshaft or axle (whatever it is I grabbed the big end) and shook it, there was no play so I grabbed the D.Side shaft and at the big end it flexs up and down about 2" up and 2" down, is the halfshaft broke or is it something in the front differential thats causing the shaft to wiggle so much. I can also move the shaft in or out about 1" from the diff. I also hear a clicking that gets loud after I restart from a stop, but if I baby it sometimes the sound goes away. it sounds like its a speedo cable, would that make a sound that clicks softly when barely moving then get very loud when I accelerate hard but occasionally it will go away at higher speeds it seems to do it most when restarting after driving or when I drive rough please send helpful advise to tuffytime@msn.com thanx

sounds like you need new ujoints in you axle shaft. the needle bearings have probably disintegrated and now your cross is just banging around in the caps. dont let it go too long or your ears can get torn right off the shafts and then youll need to replace those too.
