Stock rear axle pinion angle help please

[cracker]

Can anyone crawl under their stock rig and let me know what the stock rear axle pinion angle is for either a short bed or a long bed (I don't beleive there is a difference)?

 

Thanks in advance.

the pinion angle needs to be the same as the angle on the transmission. stock doesn't matter, just find the angle of your tranny output and put the pinion at the same angle. unless you have a DC rear drive-shaft you don't want the pinion to be pointing up. it needs to be about flat because your t-case is about flat (unless you have a crossmember drop)

 

if you're having d-shaft troubles with the truck in your avatar, you may need a TJ front yoke in order to get the correct angle without maxing out the u-joint

Don't forget to subtract 2* for pinion climb.

I'm sure cracker knows all that. :D

 

Stock readings on my LWB before pre 3" lift, the readings were:

DRIVE SHAFT SLOPE was 8* DOWN

PINION ANGLE was 5*

PINION OPERATING ANGLE was 8* - 5* = 3*

 

I'm sure the SWB angles will not the same because of the different geometry.

Thanks guys. :cheers:

 

I need to weld up some perches on an 8.8 for a stock rig and send it to a buddy a couple hours away.

 

I will set the pinion up tonight then
