1997 f250 vibration at 55-60

Iv been chasing this problem since I finished my 4x4 5-speed swap. You guy had given me a few pointers a few months back and iv worked on it off and on. The truck has a one peice shaft and I replaced it with a new shaft made for my truck with a double carded front joint and I put tapered blocks in rear(5degree). The truck has the exact same vibration. Tonight I put the truck on jack stands and ran it up to 55-60. The vibration seems consintrated at transfer case. I dropped the rear shaft and it seemed to go away. Put it back on and itís back. I put a stethoscope on the transfer case and it didnít seem to make and abnormal noise and I put it on rear end and it seemed smooth as glass. The entire time I do this I can feel it vibrating. It seems it would be the shaft but itís been on two dif shafts with two dif setups. The shaft was balanced when I bought it and cost an arm and a leg and didnít fix it. I thought forsure it was the problem. Is there a chance it could be the transfer case and it just dose it when it has the load of the drive train. I also checked oil in transfer case. Itís at the right level. I didnít drain it to see if there was any shavings in it. Itís new fluid when I installed the transfer case. Any help would be greatly appreciated. Iím not sure what to do and donít want to through more money at it and it not fix the prob. Thank you in advance.

My 95 Bronco had a lift and sat on 35's. I had an unloaded vibration at 55-70mph. I replaced the tires, and had the driveshaft rebuilt and rebalanced but the vibration was still there. On a whim I swapped in a transfer case I had laying around and the vibration went away. Never did figure out what was wrong with the transfer case. Everything felt tight and smooth.

I hope that’s the case. I am getting one from a salvage yard for 310 with a one year warranty along with labor. It’s got 150000 miles. I just don’t know enough about transfer cases to know if it’s posable the vibration is coming from it.

Make sure the nut on the output yoke is tight . That will cause all kind of weird vibrations.

The rear Nut for the out put yoke it tight but I will check the fron since it’s got play. That essentially spinning during vibration though

The chain in the case is rotating any time the driveshaft is turning on the 2wd output , so I suppose you could possibly get a vibration of sorts ... Iím like you , I think it needs a transfer case .

Seems like it’s the last thing left.... I should have also said the trans and transfer case came from a f350 with 206000 miles or so.

I pulled the transfer case out last night and all seemed to be well with it. I’m hoping a dif transfer case fixes it.
