Front pinion anlgle sucks

[JEBSR]

I know this has been discussed a million times but I have searched for two hours and not found the answer sooooo here goes.

After the last lift I put on my front pinion is angled down around 8 degrees. In four wheel drive it's ok until I get on it real hard. I can hear the front ujoint bind up. It drives ok, steering self centers, etc.

My question is how do I find the happy medium to shim the axle up correcting the angle without disturbing the steering to much?

 

[resurrected_jimmy]

trial and error for the happy medium. shim it so that the u-joint won't bind and see what happens then adjust from there to what you can live with steering wise. Or go all out and get the pinion angle correct and have the knuckles cut and welded.

Down 8*? Got a pic?

That shouldn't self-center then, should it?

 

[resurrected_jimmy]

That shouldn't self-center then, should it?

my guess is NO !!!!!!!


Thinking about it, sounds like the shims need to be flipped around

Or the springs are installed backwards.

well one thing you can do (people do around here) is 1 of 2 things...

1 divorced t-case
2 have axle rotated...

they even rotated the axle on xtreme4x4 the show...

they grind the welds off the spindles and rotate the pumpkin.. this leaves all steering geometry alone..... I almost had to do that... I was up 12" and even with a 2" drop tcase I still had a bad front d-shaft angle.... I was gonna do rockwells but NJ said no... so down she came and didnt have to worry about it...

Look at that shaft angle!!!

stock push pull steering sucked majorly too

I wouldn't think so. I put longer shackles on mine and it wouldn't self-center, and it was no where close to being pointed down. I wouldn't think it would even be drivable if it was 8* down.

Do ya'll think we may be interpreting this wrong....... maybe he means it is 8* below where it needs to be? 8* below horizontal doesn't really seem like it would even function

Ya, I'm thinking for sure we are reading it wrong. A pic would help more than words probably.

if the front cv binds is that really bad? or is it alright if its just for 4wd use for a while until a high angle shaft is made?

 

[resurrected_jimmy]

Its bad, you need to fix it asap

 

[Citizen Rider]

The binding will find a weak spot. And puts lots of stress on tcase, mounts, everything.

That's what I meant, sorry. I just got home and it's raining but I'll try to get it in the garage and remeasure it to be sure. I'll get a pic if I can.
It has 4" spring with a 7" shackle.

Just take 2 seconds to think about it, what could be good about the CV binding? Oh and why would it be okay to use in 4wd? Thats the only time its going to bind

 

[JEBSR]

Ok got some pics but didn't have time to recheck angle.

 

[Chaddy]

Did you take a grinder to the yokes?

 

[JEBSR]

no not yet, gonna do that and the shims at the same time. soon...
Taking it out every thurs for next three weeks for training so got to keep it together until I get shims figured out and ordered.

well i was saying that its the front, if it was the rear it would be binding all the time and it would not last long at all. but i thought that since its only when 4wd is used it would last a lil since i wouldnt use 4wd alot.

i took 2 seconds to think about it, and i was just wondering if a little binding would be ok or if its the kind of thing that will rip it off or something. ive got a new 1350cv shaft but its too long so i cant put it in til i do my 52 swap. im jus seeing if this shaft would get me by for a couple weeks

I think the problem is your shackle. It is so long it is rocking the axle down just put some shims under the springs and bring it back up to where it needs to be or move the rear mount up to the top hole on your shackle. I have 4" springs and I run the 4.250" shackle from ORD. and my pinion is almost perfect and my caster? is at 8*
