Deuce Transfer case

[kcollum]

Hello, I am new to the madness, I have purchased a 1970 Jeep Corp. Deuce. in good shape. It has a vibration in the floor board at 25 mph and above. Checked all fluid levels and all are good and clean. I remove the front drive shaft and took a ride, no more vibration. Front drive shaft had small amount of play in u-joints so i have replaced them. Re installed and vibration is back but not as bad. The front output
yoke on transfer case has a little play not bad and no seal leak could it be I have a bad pinion bearing on the front wheel drive output of the case?

Thanks for any input.

Bent/unbalanced drive shaft, or something in the front end that is transfering the vibration from the front end to the transfercase through the shaft.

Welcome to the site. Before anybody else tells you try and use search and also look in tm You can download them from site. Your driveshaft maybe out of balance.Any dents or a missing wieght could throw balance off. I would also go through do a good frontend inspection for any loose or wore out parts. little wear here and there ends up being a vibration or a shimmy.Just my Hopefully someone else will chime in now. Ksm715 beat me too it

Thanks, I will have the drive shaft checked for true. With shaft out I had no vibration so it might be the shaft.

I have had issues with the pinion bearings in the front axle coming loose. While the DS is out, see if you can move the flange on the axle up/down. Thats been my vibration source for 2 yrs in a row.

Thanks, I will take a look at that and see if there is any play in the bearing.
