Pinion angle

[jow003]

I'm putting in toy axles and I'm trying to find out what the pinion agile should be. Tried searching and came up with nothing with any real answers. Both front and rear shafts will have cv joints and as I understand that has something to deal with it.

Thanks

with a CV, you want the non-CV end to have close to 0* operating angle

because you have an offset t-case and a centered axle, that will never happen.

i always set em where if it was a cv the pinion end should "point" at the t case. non cv shafts i usually set at about 3-4 degrees or so
i am sure a more technical answer will follow...

you gonna have some decent droop? if you got dual cv's on a driveshaft, then I'd say point your pinion up at 2 degrees. this will mean that under some good acceleration it will increase to about 4-6 degrees. each ujoint in the cv will then be at 2-3 degrees under acceleration which is within tolerances for keeping a long cvjoint life. also, this gives you extra room to breath when drooping.
you can't really do anything about the sideways offset, you're pretty much stuck with that. if that sideways angle is too high, you'll have to keep driveshaft rpm's down to maybe 3000 or so.
. the driveshaft pros recommend no more than 2-3 degrees on a ujoint if you're gonna run it to 5000 rpm's.
if you have just one cv on the driveshaft, then put that at the t-case and do what you can for the pinion. but you should take this to mean putting another cv by the pinion.
. do you know how to measure your angles?
. when I made my dual cv thing, I had to custom make a bolt on flange for the pinion, then make a custom male/male adapter to center the chevy cv. I got a real good driveshaft guy down here and my cousin had a lathe in his garage, so that helps.
hmm, if you had a rear disconnect, you could run around mostly in front wheel drive, that axle should be offset, so the angle'd be a lot less. also that driveshaft should be longer, so the angle is less. then you could just engage the rear for 4wd.

Point the CV at the diff in the back. I ran a toy rear with sammy case with a toy cv and had no vibes. The front is different of course because of your steering. When I did my yj swap I set the front pinion to where it should be stock and still used a CV with a TG long slip. I never noticed any issues.

.
now this one is a suzuki adapter ring I'm holding near my chevy cv. they don't go together, I'm just showing how it goes. each male side sits in the female centering ring in the cvjoint and the custom pinion flange I made. I know I could have made the flange male, but if the flanges get boogered for whatever reason, I can put a new adapter in there and not have to remake a whole part.

cajun, do you get any vibrations? thanks for all the info thus far

[cajunsuzukispider]

no, i ran around town for a year with a 1.6l pushing me and everything was fine.
