Trasfer case hits bottom of cab 4in left 1in trasfer case drop a d still hits when crawling new transmission mount ant motor mounts both sides don't now what else to do

 

neither do I, but somethings got to be amiss, as I have never heard of this before

Is something unusual in your setup ?

articulate on something, crawl under and observe

Do you have extended bumpstops to compensate for the 4" lift ?

Inspect your engine mounts

are you sure its not hitting the x-member ?..this IS a common problem

 

I dropped my transfer case with no issues (3.25" lift) - Please post an image of your problem to assist us understanding your problem. With a 4" lift, you probably need to change the nose on the transfer case (SYE) and get a new drive shaft.
