Default driveshaft/sye problem

hey guys i been having hell of a time, ok first was the sye problem in which the drive shaft fellout so i just dropped the rear 1 inch and by the books it would have put my driveshaft back 1 more inch resulting in no more vibration and no more shaft fall out but the drive shaft part that goes into the sye is at the same place it was when i started before the drop so now i dont know what to do, plz help!!!

what lift do you have
do you have the stock drive shaft in it still
I don't think you have a SYE or you wold not be having this problem
if you do in fact have a sye then your shaft is to short for the lift you have

lowering your jeep 1" will not give you 1" more bite on the shaft
depending on the angle you would be lucky to get 1/4" more

stock driveshaft have no clue, and you might be right on the sye, but as far as the lift kit its is an older trial master. but i had 2 inch blocks then i cracked one and the orielly auto parts near me only has 3 inches so i bought those just so i could have it sit and not get in the way while i waited for the 2 inches but the i drove it the the gas station long story short driveshaft fell out so then 2day i put in the 2inch blocks but the shaft still stuck out the same but before the 3 inches i never had a problem now i do so i dont know what to do

Do you have a slip yoke eliminator (SYE), or is it the regular stock slip yoke that goes on and off the T-case with no bolts? I do not know how a bolted on driveshaft (which you would have with an SYE) could fall off, unless it was missing the bolts. If it bolts up on both sides, and it came off still because it is not long enough, you would be lucky if that is all that happened.

As stated, there is not a 1:1 relationship with lift height or transfercase height versus driveshaft length. As an example, on my front driveshaft, I had the axle flexing about 12" from droop to stuff (at the shock; the actual diff movement would be a bit less than that), and there was about 3/4" difference in the length of the driveshaft. 1" up or down will not translate to very much movement at all in the driveshaft. You need a longer driveshaft to run at the height you are at. No better or cheaper way around it.
