trucks vibrating

[steelhorserider0891]

so a couple weeks ago i raised the back of my blazer with shackles from O'Rielly's. after i did nothing seemed different. to day i hooked the car hauler to the blazer, still no diff, then i pulled the v8 shortbed on it, and took it for a short ride..then i noticed some is vibrating after the weight of the truck was added..thinking its my drive shaft pushed into the trans to far maybe. or maybe the pinion angle is off when this weight is added. thanks for any help..

well Have you hauled this truck with the blazer before? Our car toter when empty whipped like a basturd, come to find out toe was on on the trailer. Maybe something like that? Need a little more info.

its not the trailer that is vibrating or anything wrong with the trailer..its is something to do with the way i raised the blazer (the pulling truck) and the weight of the trailer and whatever is on it, squattin the blazer..so im thinkin since i raised it with shackles and the weight is changing the pinion angle enough to push the driveshaft into the trans..the pinion angle is all jacked up when this happens i think..never did it before i put the shackles on it.

Yea its gonna be somthing along the lines of pinion angle.
