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)

bump, anyone know what the factory angles should be on a ext cab?

 

[NORCAL SS]

do you have a carrier bearing kit on it?

 

[nick993]

they shouldnt be like that. whats your drop and what did you use to lower the truck? im guessing its lowered in someway cause a stock truck wouldnt be like that.

 

[Ketis]

i have the djm 4" control arms up front, djm carrier bearing relocation bracket, and djm flip kit..

Bump

 

[nick993]

so a 4/6 drop. pictures of the carrier bearing? and 6 degrees downward on your rearend sounds like its pointing too far down and might need a shim.

Yea, take some pics of the driveshaft coming out of the trans, and at the carrier bearing, and at the rear axle. I understand what you are trying to say with the pic, but real life pics will help us.

 

[Ketis]

well, if i was measuring my angles right my front pinion angle would be -8.5 and my rear would be -11?

Does your axle look like this, but pointing down?

Should look more like this:

 

[Ketis]

i would have to lower my carrier bearing alot to make it look like that,

but yes... mine does look like the first pic except down, and the driveshaft is angled up a bit. ill try to get pics or something

 

[nick993]

a 2 degree shim with the fat end on the backside of the axle should fix that. this will point the axle up more.

 

[Ketis]

well i have the djm flip kit with the adjustable pinion angle..

 

[nick993]

i dont know how that works, but whatever you can do to get the rearend pointed higher should help.

 

[matts_sierra]

that aint shit for angles. should see mine. thats some scary shit right there

 

[Ketis]

thats what im thinking that my shaking isnt because of pinion angle.

The shaking only comes when i hit small bumps above 30 mph, if i go over large elevation changes where the suspension articulates, it does not do it. also i get no vibration caused by speed from 30-100 if the road is smoothe

 

[nick993]

shaking from the rear or front?

 

[Ketis]

the whole truck shakes, it feels like the rear end is hopping, but if i let go of the steering wheel it shakes aswell...
