Default Something Strange with these angles (another pinion question)

Here are my measurements of what i have currently on the truck.

Its either horribly bad or something else is fucked up.

I get a sensation similar to wheel hop every time i hit a bump above 30mph

here are my angles of everything

(sorry for the crudeness of the pic)





on the left is the rear end, middle is carrier bearing, then tranny.

shouldnt it be an angle of something like 3*?

also I dont think your driveshaft is gonna have an effect on wheel hop, thats gonna be a traction issue due to the good ol drop

The pinion angle has a lot to do with wheel hop actually.

Its not wheel hop from accelerating, it just feels like wheel hop. The rear end is bouncy when I hit small bumps. But is smoothe under acceleration

I guess you could try shimming your rear end, and shimming the carrier bearing down some. Those angles look all kinds of messed up.

hmm, I figured dropping the rear with shackles and hangars it just made it bouncy. I figured you would only get a vibe from the driveshaft with the angles being off?

Im listening then

I didn't use shackles and hangers, I have a djm flip kit. I also have the carrier bearing relocation bracket which has some adjustability. What should I try to change?

I would think that would be worse?

I would find out what the angles are supposed to be and then put a magnetic level on the driveshaft while the trucks on an alignment or exhaust shop rack and shim accordingly

That's what I'm trying to figure out what the angles should be
