Has anyone done either or both T-case drop/track bar re-drill with just a 2" BB? I can not tell if it is the Driveshaft or the new A/T tires I put on, but now I have a little shimmy at high speeds. I have not done the front yet, but just wondering if anyone has re drilled with just a 2", it looks like it would relocated the axle a little without doing. thanks

 

You shouldn't need either at that hieght. Have you got an alignment recently?

 

I was waiting until I lift the front. So the vibration is prob the tires and not the DS? thanks

 

So you have only lifted the back? Yea its prolly the drive shaft. You shouldnt drive very long (or at all) with half a lift. It puts your output shaft and pinion at weird angles. Lift the front, then see if the vibes are still there

 

How does only lifting the back change how the pinion angle is going to be set once the fronts lifted?

 

i dont think it does.

 

Well he isn't using an SYE so the output shaft on the tcase and the rear pinion have to be parallel, right? And yes, the pinion angle in the back won't change, but since the front of the jeep is lower then the rear, the tcase output shaft will be at an upward angle, and not parallel with the rear pinion I would believe. If I'm wrong please correct me, I don't want to steer him the wrong way.

 

So what's the pinion like now:



Haha, time to get new leafs...

 

I just finished my 2" lift on my 2001. I got a bad driveline vibe at about 30. Installed a 1" t-case and it went away. The tracbar was fine.

 

Your jeep looks good!
