driveshaft vibration

[ajfriz]

I was experiencing some pretty decent vibration so I decided to first check the balance of the tires. They turned out great so I decided to just replace the ujoints because who knows when the po changed them last. While I was replacing them, I noticed that the yoke on the output of the tcase was loose. After I took the driveshaft all the way off I noticed that the nut that holds the yoke on the case was very loose. The seal looked to be pretty new but torn a little. Whover changed parts in the tcase forgot to use a punch to form the nut into the groove in the shaft so it became loose. The question is, should I expect the bearing to go out on the output of the tcase? I checked for excessive play and it seemed to be good and there isn't any vibration or unusual noise. I have only owned this 4runner for about two weeks now and I don't know how long the vibration was existant before I owned it.

edit:I forgot to mention that this is an 86 4runner with a 22re.

I wouldn't worry about it too much, just check it every few months to see if it's gettign loose.

There was a bolt loose on the driveshaft where it connects to the transfercase and it vibrated real bad. It is amazing what one loose bolt can do. I check them all the time now.

Should be ok just replace the seal and recheck every once and awhile. If it loosens again use some of the temp locktite, blue if memory serves.
