Figure with a hack n tap you cut am inch to 1 1/4" of the output shaft. And at the same time you cut the sye flange to fit the new shaft length. Only main difference with the slip yoke DC and the sye one is the lack of the bolt to hold in place and the slip yoke DC is hanging out further

How are you supposed to center your axle then? I thought the centering pin was supposed to clamp the shim to the spring just like it was another leaf.

You're right. And the nut is supposed to sit inside the hole of the u bolt plate, not on top lol... Then trim the excess off.

I believe yore right. Suppose to separate everything and add the shim like a 5th leaf/additionAl leaf then clamp down

Damn you. Youbeat me

What years is the air box lid on the right for? 97+? You can see that there's some sort of connector on the tube that goes to the TB. I've been googling around but I can't find any pics of a 97+ lid.

Well it will still center it afaik, but maybe not be retained as well *BUT* if the u bolt was gone, it would come off... Is that not good? I thought it was supposed to be clamped on to the leaf, not just sitting under it but duder did it not me... but I also doubt the structural integrity of a 3/8" bolt past just keeping them from not slipping side to side. If I put this on, it'd go leaf pack bolted together --> shim slips over center pin head --> center pin head goes into spring perch hole --> u bolts tighten the spring plate down, and the weight of the vehicle keeps the spring pin in the perch & therefore shim in place. Do you think it would start to walk out one way or the other over time? I do not want that. This is what I get for being lazy when its cold.

I don't know how much of a part the center pin plays structurally past just keeping it aligned to the spring perch.

What diameter is the hole in the shim? I thought the center pin goes through the shim then through the rest of the leaf and then the nut goes on. This new setup gets uclamped down to existing g leaf perch

Shim hole is now 5/8" (duder drilled em out) which matches the head of the center pin (and the spring perch hole), not the nut. Nut threads on top of the spring pack on the threaded portion of the center pin (I just want to make sure I'm not mixing up terminology and throwing everyone off).

I had to drill out my spring perch a hair to fit the center pin when I installed my leaf pack. Rubicon Express 3.5" kit w/ the stock center pin that came with it. I imagine it'd be extremely hard for it to rotate because it'd end up hitting the u bolts anyway.

I'm just going to get another pack of shims & center pins and do it myself.

9 quarts?

2.5 to 3.75 quarts.

tssguy123

Right... so that's not the same thing as the PCV hose that goes in to the side of the box? So the one on the right IS for a 97+?

bulrid8

Sorry about that, some how my phone jumped back to page 8 on this thread, so that and old post. But, yeah kinda freaked me out that he had 9 quarts, for a pan drop.

cruiser54

4.0 never had PCV. Only CCV.
