Ohhhhhh, I see...I'm not too familiar with the expo axles...

Wow, I feel like a n3wb...

 

Screw it then, I'll use the ranger shaft till she blows. LOL. Ive got a spare JY ranger axle anyhow so I should be good for a while... who knows, in that time I may find a way to source just the SL flange and make that double cardan JY axle work afterall.


Have a new question for you guys. How do I go about setting pinion angle when I got to setup the explorer axle for the spring perches? What is the angle supposed to be? I messed with pinion angle correction when I lowered my 94, but can't remember any of the process of measureing and/or setting the correct angle.

 

i just slightly tightened my ubolts then eyeballed the angles to match each other.. tacked then went nuts with the welder

 

big thing is first just eyeball it... make sure that your pinion nose and axle come to a straight line. If you are useing the SL blocks you need to account for the 2.5*(IIRC) taper on the blocks. Other than that info i cant really say... I eyeballed mine and works just fine....

 

I think your wordage confuses me. I think I'm confused on what you mean by pinion nose, and what you mean by a straight line between them.

I know to eyeball it to get it close, but when I set the pinion on my 94 I had thought that the angle difference was supposed to be 2* to account for axle wrapping on accel. But being lifted is making me overthink this and worry too much LOL.

 

Let me clarify.... Pinion Nose='s the very front of the differential... the part where you bolt your drive shaft flange to the differential. And by straight line i mean, well just make sure that there isnt any crazy angles from the d-shaft to the differential. Im pretty sure that 2*'s sounds about right. But then again that can change with each application based on lift height, springs, shackles and blocks.

 

Ahh ok, thats what I thought you meant :)

Here is a quick crude sketch I did

So basically, if memory serves me right, I measure the output shaft angle, then add two degrees to that, and that is what I should set my pinion angle at.... (If output angle was 15*, then pinion angle should be 17*) sound right?

 

how come your painted it all up if you still have to weld perches on?

 

.

 

Hey matt does the pinion flange yoke on the ranger (thing u-joint goes in) bolt onto the pinion flange on the explorer rear end or do you need the flange yoke off the explorer?

 

bolts right too the expo flange just fine, both axles share the same flange :)

 

Oh good cause I am going and removing the axle tommorow and didnt know if I had to take a press to get the ujoint out of there. Thanks.

 

have u found perchs yet?

 

Yah, I bought some Mopar Universal 2.5" perches from Summit. $12 for the set. Now I just need to get a 220V line ran in the garage for my welder. That, and I need to source various other parts for the rear end before I swap it in like parking brake cable and the parking brake itself.

 

good. i need to get dismantaling mine soon. i was just wandering if you found some because i found perches, tabs, u-bolts, and plates from ruffstuffspecialties.com. all i need is paint, pads, brake and ebrake lines.

 

hrrrrm. Me thinks I forgot about shock tabs. :(

I had planned to use the stock explorer spring plate/shock mounts like I did on my lowered Ranger. But, being lifted and a SOA setup, that probably will not work.

 

4 wheel parts keeps them in stock if you have one near you.

 

Matt, i believe they said my pinion angle was 16* they said that was about perfect for the lift. what the alignment shop knows? idk. lol

but i just plan to do like scott said. slide it under there, tighten the ubolts some and twist it till you get the desired angle.

 

There is one in Salt Lake City, but, after the gas I spend to get there, and wear and tear on the truck, it will probably be the same to have them shipped to me. Thanks for the heads up though.

 

i got mine from bluetorchfab.com

same with the spring perches. they make some sweet stuff. kinda pricey tho.

 

Thanks for the info Zach. That will come in handy.

 

but if 16* does not look right on your truck dont weld it that way.

what are you running now? superlift blocks stacked? or AAL and cehvy drop shackle.

measure where it is now and make it close to that. but you want the angle of your pinion to be close to the same as the angle of the driveshaft. maybe tipped down some but definitely not tipped further up

 

Just the Chevy shackle right now. I have some 2* shims from when I thought I had to adjust the lowered ranger, but was wrong. So I have those for a +/-2* adjustment should I need them.

And you're right, the pinion should be tipped 2* down (towards the ground), relative to the degree of the output flange.

 

actually i would think if you put an aal in the rear with the drop shackle the angle would be close to perfect. just mount the new perches in relative to what your stock axle is like.

 

Didn't think of that. Did you have blocks or AAL with your SuperLift? If AAL, how did it ride? I have the Bilstein 5100's out back.
