I have been researching for a while now and readng up on the replacement of the driveshafts. I understand the reasoning behind the replacement due to the type of joints that come stock on the JK. What I don't understand is this...on an automatic (which I have), the front d/s can hit the tranny skid when the JK is lifted. How does replacing the front d/s with an aftermarket one keep this from happening? I have looked at mine sitting level on the ground with a 3" lift, and I can see where it would hit, so how do the aftermarket ones eliminate this?

 

Okay, so I see that the aftermarket d/s is narrower, thus helping to keep it from hitting the tranny skid. So then my next question would be...how high of a lift can you go with a narrower d/s before you would have to remove the skid or cut it out?

 

I think the question is more how long can the shock be.

 

So, even with the mods, there really is no way to keep the d/s from hitting the skid? That sucks.

 

What do you mean exactly...it's the transmission?

 

And I have a leak now from the tranny pan after my OE shaft has hit it alot. With a 3.5 lift and 35's. But I also have wheeled alot of the toughest trails in Moab and flexing it to the max!
