Need Advice on Driveline Vibration after OEM upgrade.....

Did you leave your CB drop in after you flipped it? That might have made the angle too extreme. I'm just shooting from the hip here.

 

Nope removed it

 

Well, I'm out of ideas then. Good luck though!

 

Thanks brother this is why on the next truck it will get leveled in the front and nothing else. Looks good but not worth all the aggrevation.

 

It sucks that every truck is so different in some aspects. I lifted my rear 2" and am not having any vibrations.

 

Overload in or out???

 

Overload in.

 

ICON 1.5

 

BUBBLES 4.6





Am I doing this right?

 

Bubbles huh???

 

I was confused by your ICON 1.5 response and it's relevance.

 

Your leaf pack is it an ICON 1.5 Progressive AAL???

 

OH. No, it's a Wheelers 2" AAL.

 

Same thing just doesn't say ICON on it. So no shims , no nothing???

 

Absolutely nothing. Guess I got lucky...or I'm retarded and don't notice the vibrations. Pretty sure they're not there though. It's not progressive either.

 

Hmmmmmmmmmmmmmmmmmmmmmmm

 

Here is a driveline angle calculator - measure your transmission angle, both sections of driveshaft, and the pinion angle of the rear diff. Use a digital angle finder accurate to 0.1 degree - I think many smart phones are capable with an angle meter app, or buy a digital angle meter from fleabay or elsewhere. Fill in all info in the calculator, since you don't have a tandem axle, enter your pinion angle for both axles and the "interaxle" driveline, so it is calculated as one unit.

Thanks brother

 

Ok Update!!! When I originally did the carrier flip I didn't pay attention to why? Only after installing the washers did I check the CB due to the vibrations coming back with the washers. The CB flip actually moves the driveshaft closer to the frame, which is what I needed due to only having a stock suspension with the TSB leaf. I think that the flip isn't good for modified lifts, but the CB drop should be considered.
