Leaking pinion seal and vibe issue. Need help.

Ok so I did some research but no one really describes what I am looking for. I bought a truck a few years ago. I added a 6" Icon lift. After the lift install I had some vibration during take off. I kept adding and removing the carrier bearing shims nothing helped. I then had all the u joints replaced. This helped slightly. Last year I had the trans rebuilt. My buddy used a sonnax kit instead the trans go kit. Didnt realize until he was done. With the shims he installed it bangs second which is very nice while hauling but not so nice for DD. He hasnt gotten around to adjusting this yet.

Today I notice gear oil everywhere under the truck. Its coming from the pinion seal.

First question: Is this from the vibe or trans shifting?

Second question: Could this be a pinion bearing issue?

Third: Can I just remove the driveshaft, pinion nut, yolk and pinion then replace the seal if I torque the nut back to the right specs, without doing a complete overhaul?

Fourth: If so what do I torque the nut to? Or how bout a write up on this...

i would check the bearings on the diff. But pinion seal is straight foward, impact it in. I had to use a 1' impact to remove my nut.
