yah...vibes

yah so i pulled the shafts and tightened up the bolt that holds the rear yoke on.
it was a little loose. Vibes are still there but not as bad now. so i guess tightening that bolt helped.
i also noticed i left the jack under front diff. so my driveline angle measurement was off. my front pinion is at 1-1.5*. but the front driveshaft angle is actually 11-12*.
im thinking about still shortening the lowers but im gonna get the tires checked for balance first and also throw some longer shackles on.

cool got it figured out. driver side front tire somehow got way outta balance in the last 2000 miles. test drove it no more vibes. also tightening the bolt on the yoke helped. i still want to point my rear pinion up a tad bit so im still gonna get some shackles but other than that its all good.
i guess at least for now the 18.5" lcas and the 17" ucas are good.
the purpose of the longer arms in my case was to better center the axle up front and also with the longer arms less of an angle for better articulation and handling on road.
plus the lowers were free.all they needed was new bushings.
