my 50/50 4-link in action vid enclosed

i dont think that going from +3 degrees at flat out to 0 degress at full lock is too bad, mind you this setup only provides for around 8 inches of lift, seeing that its bag behind axle setup, im not really into big wheels or hittin sides either...
anyways heres a close up of guage at flat out...



heres the video, oh yeah this is on house air at around 65 pounds regulated...

what is your pinion angle at ride height? looks like the pinoin is pointing to the ground HARD, are you measueing the angle in that vid off the spring perch or sumthing?

naw james its on the pumkin casting bro

heres a pic of where the guage is at on the punkin casting

here are some other shotswith driveshaft in

You need to set the angle finder so it's parallel with the frame, not angled with the pumpkin. If it's deflected from the plane of the angle you're trying to measure, the reading will be slightly lower than the actual angle.

Yea you need to def. redo ur pinion angle that thing its gonna vibrate u out the trk like that..i usually set my angle finder on the yoke where the drive shaft bolts up and go from there.

the "wings" on the pumpkin are parallel to the pinion shaft
this setup is four yrs old, the only thing cahnmged in the last cpl yrs is ive been doing my stockfloor bd.
driven to greenville twice, from nashville no vibration ever...

if you are only raising and lowering the back, your pinion angle isnt going to look lik eit changes a bunch because you are only measuring the change in relation to the GROUND. The trans/carrier bearing angle is changing too if you are only lifting the rear, so you would need TWO angle finders and to subtract the pinion angle from the trans/carrier angle.


To measure pinion angle change with only one angle finder, you level the frame on stands and let the rear droop the forecasted 8 inches of lift. Then using a jack you jack up the rear end. This keeps the trans (or in your case the carrier bearing) pinion angle constant.

I'm not saying it will work worse or better, just saying make sure you are measuring correctly is all. That video is not measuring correctly.

In the pics it looks like the angle finder is angled in a bit instead of straight front to back.
