I have a 3 1/2" Metalcloak duraflex lift and an aftermarket front drive shaft (2 1/2" diameter). With the stock driveshaft, I know its common for the DS to hit the xmission case when flexing. I thought I would solve this problem with the aftermarket DS. The control arms are properly set and the DS angles should be ok (had a reputable shop install the DS). The axle is centered within 3/16 of an inch. I just got back from off-roading and notice that I am still hitting.
Am I missing something here? How do I fix this?

I'm curious to find out as well why it would happen. Would the correct size bump stops help in correcting this kind of issue? Personally I don't know but that would be my guess, as well as maybe installing limiting straps...Here soon I will be around the same size lift myself and hopefully my stock DS last for the time being so that I can save for an after market DS for both front and rear. From what I have read its usually the rear in the 2 dr that should be addressed first...I have a manual.

I'm hitting on the pan and have a shiny spot going up from there. The after-market DS is from a local driveline shop. So far, the only thing I can think of to eliminate this is to move the front axle over (to driver side) maybe a 1/4 inch and see what happens. I don't like things that are not symmetrical though, so the thought of the axle being not-centered is annoying.

Yeah, that's not good. Actually, 'biggie332' in a post above, said it. "Limiting straps". I had the same issue and ended up using my high lift jack to raise each corner until I saw the driveshaft just touch the pan, then, I measured the distance of the axle housing to the frame. I made up my own limiting straps using 5/16" plastic coated aircraft cable to stop the axle just before it would hit the trans pan. It's worked great so far. You will lose a little downward movement of the axle but not a whole lot. I'd send a pic but I'm not able to right now. I'll try to send what I did soon. And yes, if you move the front axle over another 1/4 or so, it will help quite a bit.

After market driveshafts will give you about 1.5" more axle droop clearance over the factory shaft. Installing a limit strap at the differential will prevent contact while still allowing each wheel to droop.
