pinion angle

i greatly appreciate it man.
i set up the 4-link on my buddy's 2001 frontier and set the pinion to what it looked like with the leaf springs on it.

the u-joints just went out on it, and they are not serviceable (sp). so he had to order a whole new drive shaft ($350) i wanna recheck everything on it and adjust as necesary so he wont have this costly problem again.

i may email you with a couple questions along the way if thats ok.

so tranny pointing down 2 degress plus the driveshaft pointing up 3 degrees, that equals out to 5 degrees at that joint right?? what do you do at the carrier bearing when it is mounted flat, assuming we are working witha truck using the frame leveled at 0.

oh and naked chicks w/ beer would be outstanding...

I wouldn't say add the two together because in your case it would end up +1. I'm going to help you feel your inner self with meditation Cris. Sit Indian style with both feet pointed up and picture one line that is 2 degrees down from level and another line 2 degrees up from level. There is 4 degrees between them....that is your working angle......ummmmmmmmmm.......ummmmmmmm.

aw dammit. i thought i had it.

so i want no working angle to be less than 1/2 deg but not exceed 3 deg. and i want the pinion set equal opposite to the tranny so that they are parallel to each other?

hahaha so that what i said, tranny pointing down 2 degrees, and driveshaft pointing up 2 degrees, thats 4 degrees. now that im past that finally, when you get to the carrier bearing, should it be mounted flat? then the rear driveshaft, could that be pointed up somwhere around 4-5 degrees to compensate for the front shaft already at 2 degrees up? that way that 2nd joint will have like 4 degrees working angle?

WTF, I responded but guess what...it's gone. If I was gonna put money on it, it probably went to the same place as my T-shirt. Anyways Cris, the bearing is encapsulated in rubber so it can be misaligned slightly, I'm talkin like 2 degrees from perpendicular to the shaft. But since you like tits and beer lets go for perfection. You can either make a crossmember that the carrier can mount to and set the carrier perpendicular to the shaft or make an angled spacer. I would build a crossmember for this particular scenerio since your working angle is 4 degrees and could be lowered to make it 3.

If the front shaft is up 2 degrees and then you put the second shaft up 4 degrees...that's 2 degrees operating angle.

hey andy think you could draw up a quick diagram like cris's but with what your explaining.

I take it you didn't sit in the forest next to Cris. I'll draw one up on CAD and send it to Cris to post. I think I'll send it on microfiche so he can enlarge it.
