Did you do it yet?
Tell me why a 4 inch suspension lift is bad

Jesus this thread turned out to be awful.
I think what the OP was getting at, and a better way to ask the question is?
Some people are currently having issues with CV angles and ball joints when running on the top perch.
Would dropping the differential and lower control arms down to keep the CV Axles level work to alleviate that stress? What other potential problem could arise?

The problem is now you are shifting the stress further up the system. Placing wear and tear on more vital components, that may or may not be stronger. The stress must go somewhere, unless you drop everything down, including engine and tranny.

The next is the front drive shaft u joints..

I think several people miss the point in the question... For many many many years 4x4 have been lifted. IFS, solid front axle they have been lifted, there are TV shows now based on 4x4 fun. If you create a weak point by increasing the CV angle then lifting without increasing the angle means no added stress of the angle. So of course no added stress does not move that stress that does not exist. However depending how its done it does create stress other places (usually front drive line because thats a new angle). The problem is the short distance the front drive line travels creates to much of an angle or an odd angle. These are not new problems never heard of before and Jeeps and have been dealing with this for decades. There is no perfect way to lift the truck unless you have a complete ground up redesign of the entire system. However given the flaws people have still been doing it successfully for many many many years. You just know the flaw before you start and watch and replace warn parts as needed.. There is no magic fix that will make any of these trucks last for hundreds of thousands of miles. No matter what you do its not going to happen,even if you leave it totally stock...

dont even get me started...
if you want a lift do a spring lift.
putting pucks to raise up the cab wont justify the size of your...

So basically what I said, granted no, the stress is not physically moving, you are just creting stress somewhere else. Would you rather replace CV's or another probably more expensive, harder to get to.

Well it becomes comparative. Replace cv axles every 10,000 miles or replace the u joints in the front drive shaft every 60,000 miles. The stress is comparative to the part failing. U jpoints at 50 each every 60,000 miles is better than cv joints every 10,000. A proper lift will only create a small amount of stress to a known value by lifting 4 inches. the equation 4(lift x joint) devided by distance over mass divided by qty of u joints ... In the front suspension the lift is so dramatic a factor it creates the lift over 4 divided by distance 1/3 of driveshaft or 3 times the stress of u joints for cv joints.. Yes a 4 inch lift makes sense because it spreads the stress over a greater distance and divides by 2 u joints. Yes it will fail eventually but you would get 3 times the life times 2 at the ujoints over the cv joints. Just a basic calculation though...
