I have a 89 xj with a 6.5 in lift with a sye kit and issuing a front srive shaft on the rear. So last time I went out wheeling I came off logging road and noticed a vibration which got worse. While I’m on the accelerator it’s there and gets worse but as soon as I put it in neutral it goes away. I have put it up on jack stands and noticed that where the shaft connects to the sye on the sye side it wobbles and has play if you push it up and down. Picture shows where play is.


How can I fix that

 

Is the play in the yoke on the transfer case side or in the CV joint itself

 

2 x 4.3L XJ asked . there are a lot of parts that can be bad .
