Bad noise/vibration after flip kit install?

like they said this will help others who have similar problems

james, you post whore...

About pinon angle...what's Ford's spec?

I don't have any shims on my truck, but then again, I don't hear/feel anything out of the ordinary...just worn out factory shocks.

ford spec is 2 degrees i think. should be parallel w/ the tranny but 2 degrees or sumthin lol

awesome glad u got it fixed

so you the hole more to the rear?

i'd go ahead and check your tranny rear seal, check if it is leaking

the pinon angle must be the same angle
at tranny. find the angle at tranny when
at ride height that is what it needs to
be at rear end
