A more than usual Tech question about Shackles...

Ok normally I would just call and talk to the company but since I got them from M.O.R.E. i have a problem. I guess they are all out at moab this week. So I come to you guys.

Ok so I got some 5/8" boom shackles for the front. You might have seen my other thread where the passenger side snapped in half. The first time i ordered the wrong size bushing for my leafs. So I called and they were great about shipping the correct size 2 day air on their dime. (I highly appreciate that! Great company to deal with). So I got my bushings in yesterday. Here in lies the problem.

The cutout in the 1" bushing I got is too small for the sleeve they shipped the first time to fit through. They are MAYBE 1/16" too big. So i just threw the bolt in there and greased the hell out of it for the time being. Im not going to run this setup for more than a couple days at the most and just 10 miles to work. Probably just until tonight actually.

Now when I tightend them down, they are angled like this \/ but obviously not exactly like that just a little smaller on the bottom due to the sleeve not being in there for the nut to tighten down on.

Now, I have a whole extra set of bushings (They shipped 8), that's why i just ran the bolt through the other bushings. Would it be okay to drill the bushing out enough to get the sleeve through and then bolt it up the correct way? Or should I just order a new set of bushings and sleeves from skyjacker? I really like the greasability (I just made a new word) of the MORE setup but if it's just eventually going to tear the bushing that i drill out, Ill just go ahead and get a proper set from skyjacker.

Thanks guys!

If I'm understanding you correctly, the front shackles are angled somewhat rearward if you were to draw a line between the upper & lower bolts.

And if the above is correct that I wrote, the rear is doing the same thing except it's angling inwards towards the cab.

If I'm right, then those angles are harsh & do not provide for a nice shackle angle for the leafs to work with.

The front shackles should angle slightly forwards at the bottom & the rear shackles slightly rearwards at the bottom.

Yea, that could be a solution.

If you think about it, all you are doing by drilling it (assuming the sleeve & bolt diameter are correct to begin with) is removing a small amount of the poly bushing. Which, if you were to get another set of bushings, the new bushing hole would be the same size as the drilled ones. Right?

Yea, correct sizing from the get go would be nice - but I don't see drilling them being a big factor for such a small difference of ~1/16" like you mentioned.

My guess is that if you have a vice, or perhaps a large enough C-clamp, and greased the sleeves & bushings, you'd maybe be able to press the sleeves in.

This is how I put my sleeves in, they seemed too small, haven't had any issue with them once in and lubed up.

Yeah im going to hit them on the drill press when i get out of class tonight. I think that should solve the problem. I just didn't want to melt the bushing and cause it to fail prematurely.

No thats a front view. Not the actual angle of the shackle.

Use a slow speed when drilling.

I think the OP is referring to the shackle looking from the front or rear straight on. The V shape would be wider on the frame mount and narrower on the spring eye end due to the bushing compressing without a guide inside.

To the OP, if you have a few spares, you may want to try the suggestion of lubing and pressing one in before drilling them out. Maybe even sit the bushing in some hot water before trying this to make it softer before trying to press it in? I would personally feel more comfortable with a press fit rather than drilling as you are not modifying the bushing. My $.02 anyways.
