Is this the t-case your going to install? https://www.borgwarner.com/newsroom...-wheel-drive-transfer-case-for-the-ford-f-150Post some pics of that swap, please. Are you going with a new case?
I was thinking of doing the same, sometimes I turn really sharp at walmart and there is a speed hump right after it. The added peace of mind would be great for the stress I put it through. The GJ 3rd "chase light" has really helped me backing out of my driveway. Next up is bump stops so when I do my tire shined wheel rotation, I can limit the travel caused by my floor jack.
i think i am going to do the GJ one.
