Notice a little vibration taking off

16 sport with 285's and notice when i take off from a set of lights or stop sign has a small vibration nothing bad and goes away soon as u get moving. now coming from diesel that would be a rear u joint. think that's the case here? its auto 4 wd with 95.000 kms

 

I feel the same thing actually. Ever since I added a SUA Kit and smoothbody kings. I can’t tell what it is

 

Me too. Just put in 5100s all around (fronts at .85) and an AAL in the rear. Immediately noticed a slight shudder when pulling out that diminishes at 15mph or so. Even at hiway speed it feels a bit rough. I’m telling myself I need tires and an alignment that wasn’t done when the lift went in. We shall see.

 

Pinion angle possibly. Need shims to correct or single piece, or double piece with double cardan after carrier bearing.

 

My buddy owns a shop and also has a 15 not lifted and put both u joints in his and still has it along with lots of other customers coming in complaining too.. he said if I figure it out I’ll make lots of money lol

 

My 08 did it from day 1 with the lift. I had it for 10years. My 18 doing same thing w lift, I just got used to it. It's so subtle that most of the time I never notice

 

Yea that's driveline angles, huge thread on it here somewhere. Most of us measure and throw axle shims and/or center support bearing spacers at it until the trucks happy. I'm at roughly 80k and thought maybe it was my ujoints or bearing since I've been lifted since buying the truck, replaced them all and still have vibes so def still my angles being a little wonky. I have dakar leaves so I think the flat nature of that pack lends itself to axle wrap.
