Alternative diagnosis/solution other than needle bearing after lift?

Didn't watch your video...
The one I posted takes into account the type of driveshaft we have; 2 piece, single u joints, carrier bearing, no cv...

 

yes watching it now and making more sense. thanks!

 

I'll bet you're running on the outer blocks of your tires if you're as high as I think you are.

Here's my truck at 2 inches on a similar tire and same wheel, does yours look higher?

 

I feel like mine sits a little higher. What does it mean to be running on outer tires? How do I verify and resolve?

 

Running on the outer tread blocks of your tires.

Looking at the front of your truck, do the front tires appear to sit flat on the road or sort of "bow legged", meaning the top of the tire is sticking out further than the bottom, like when at droop if the front of the truck is jacked up in the air?

If so the height of your springs are possibly exceeding the amount of alignment available with your stock UCAs. Options would be to either decrease the front height with a different spring that would be more manageable for the stock UCAs or go aftermarket UCA.

Can you post your current alignment numbers if possible?

 

This is how my tire sits at 37 psi.

This is the alignment sheet. Looking at it now, the tire size is wrong on the sheet. Should that matter?

 

And its a short bed...

 

Tire size and bed length shouldn't matter, numbers appear to look good, can you get a front picture of the truck, I want to see how the camber looks despite what the print says.


Are these new tires installed as well as the lift? Were the previous tires the stock, less aggressive tire? How many miles on these tires? Is it possible the vibration is due to the more aggressive tire wearing in the new tread?

 

Here's mine with JBA UCA. But I'm taking it back in to put castor at 3.1. Also to test driveline take the driveshaft out. Put in 4 wheel high. Go for ride. If it stays it ain't the driveline. If it goes away u know it's from the driveshaft back.

If it stays with 4hi turned on does that mean CBD kit is pointless?

 

Yep. Means it's not with the driveshaft. Because the driveshaft is out of the truck. Remove driveshaft all together. Drive in 4 hi. If it's still there it's another issue.

 

i took my diff drop out and it cleared up the vibs after lift and needle bearing replacement
