where to start

ok guys need some help. kinda long story but im gonna start from the begining. i had a wheel bearing and a u-joint go out in my 92 b2200. i drove it for a lil while with these problems till i got time to fix it. then i started noticing my truck had mmm.. well its not really a vibration, the best way i can think to describe it is, imagine your truck had studded snow tires on it. but its only at a certain mph and it dosent matter what gear. it happens about 20-40 mph. so i r&r the wheel bearing and race, and was going to do the u-joints. well i could get the u-joints in a timely manner around here so i needed the truck back and going and i had a 89 b2200 just sitting around, so i got the whole driveshaft out of it. same length and all the only difference was in front of the carrier bearing there is a big flange on my old driveshaft, the one out of the parts truck didnt have it but it doesnt look like its missing just looks like it didnt come with one. so i put it in, and drove it a couple of times, i noticed the slight chatter (like driving on snow tires) was still there. well the truck sat for awhile then i get in it today, and now it feels like istead of tires your riding on gears. its extremely rough and vibrates the whole truck. but its only doing it about 15-20 mph now, and you feel it on take off or slowing down, in gearm out of gear. clutch in or out. so i get home, pop the plug on the rearend, no metal on plug, everything felt okay turning the axles, looked up in the inspection hole at clutch cant see much but all looks okay in there. but i didnt want to drop a trans and be chasing ghosts, btw the clutch was replaced less than a year ago and hasnt had many miles on it. sorry its so long but i wanted to give all the details, and the rest of the time once up to speed it drives fine, just when slowing down or taking off. any ideas where to start?

i got lost about 1/3 of the way through. . . so im no help . . . somethin about a mmm, vibration like studded snow tires or somethin then i got lost. . oh well. .

then why post at all? if you didnt understand you coulda asked and i would try to explain better, thats the best way i know to describe it. i thought it was fairly clear, maybe i need to get the crayons. if anyone else has any ideas or questions feel free to ask.

dude no reason to be a douche about it. he was just stating his opinion. i got lost to and also am saying my opinion

look man he was just kidding around. it was a lengthy post. thats no way to get your question answered by being like that. i assume you checked your lugnuts and stuff of that nature. is it lowered? do you have lowering blocks on it? is all the suspension parts stock? you didnt really state all the facts. could be a few things.

well i apologize im not trying to be a douche, but i was looking for helpful info and didnt know why he would post if he had nothing useful to say. if i cant offer some help to someone im not going to reply. anyways its been a shitty day and im aggrivated, so i apologize, although i thought the crayon line was kinda funny. i know its a long post, but i wanted to get it all out since the problem started, maybe im missing something and someone else will pick up on it.

mazdawg - it is lowered with 3 inch blocks and torsion bars. all suspension parts are stock, lugnuts are tight, like i said it only does it at a low speed about 15-20 mph.

This may sound stupid, But could you jack the truck up on all 4's and put it in idle and listen and look for it?

doesnt sound stupid but i already tried that, i had it on jackstands and my wife driving it and it did fine, its not a sound i mean the only sound there is, is the truck shaking so hard that everything rattles. but on the jackstands it did fine.

and i dont think its rim or tire related already tried swapping those also

I'm jus tryin to get my post count up . . . I don't have anything useful to offer. . . ha. .
