Vibration update

So I finally got the homemade traction bar install completed today since the paint got dry. NICE difference when launching and with bumps in the road. No more head bob when letting on and off the gas pedal HOWEVER my vib on take of And vib about 40mph was not gone. Figured it had to be drive shaft related so off came the carrier bearing drop bracket Skyjacker sent with the lift (2" block and 1/4" washer) for a 2 1/4" total drop. AFter reading on here that you want roughly 1/4" per 1" of lift, I tried 1 1/8" of drop for my 4 1/2" lift blocks. ALL VIB IS GONE!!!!! Shaft is almost perfectly straight from the t. case to the differential. Smoothe as she can be. Im very happy with that and the traction bar difference. WIll let this rest awhile then start thinking about under the hood mods.

Thanks for keeping up the good info guys.

Cool! Who suggested the 1/4" per 1" lift? Always seem to work. Good numbers to remember.
