    That stock bolt is pretty long, all you need is a spacer like the pic above.

    With your ProComp 6" lift the bearing drop spacers from the manufacture measured about an inch. When I added the +3 CoachBuilder shakles it had some vibration so I purchased the 1.25 carrier bearing drop kit and the vibration was very very minimum.

    Did you had to change out your OEM front struts? AM having a wobble and bounce at 45-45 mph... Rough country I need to change the OEM front struts...

    My vibrations were because of the drive line and not the front struts. My lift kit came with the Pro Comp coilovers so yes it was changed out.

    So what is your recommendations to my bounce and wobble? Change OEM front shocks?

    The front diff should be dropped as a part of the new crossmember that is installed Witt a 6" lift kit. A 6" lift without a drop in the front diff would lead to a huge cv angle that would destroy the joints.

    As others said you most likely need the carrier bearing drop for your rear 2 piece drive shaft.

    Am new to the truck world and lift kits. I do recall seeing the shop dropped the front diff and also cutting.

    Don't know much about carrier bearing, but will surely google it. Is that also another solution to this wobble and bounce?

    The wobble and bounce seems to be something different. Wobble in the steering wheel is typically tire related. Bad wear or not balanced properly. Bounce could be bad shocks or worn springs. If you have a 2008 with stock Coilovers then you should def replace. Full length Coilovers are ideal.
