    Removing rear leaf spring bolts (Shackles/Bushings)

    ok, so I'm curious what your guys' best tricks are to get the leaf springs removed when the truck has 190K miles and it appears the leaf springs have never been removed. I ask, because I'm in the middle of adding an ORD Shackle flip/zero rate and greasable bushings (along with a 14bolt SF while i'm at it) and it took me roughly 5 hours and 3 power tools to get the drivers side spring off. Only 1 bolt was able to be pushed through the bushing, the others were frozen/rusted together, so I used a 4.5" cutting wheel, a sawzall and a 7" cutting wheel (My wheel was too thick so this wasn't much help) and ended up cutting the front bolt...the shackle is still attached to the spring though, haven't decided how to tackle that yet. I scarred up the front hanger pretty good though and i'm just trying to figure out if i'm making it harder than it is.

    I moved onto the passenger side and i cant get any of the bolts to push through, it seems they are all rusted to the bushing.

    Just seeing what your alls best way to handle these are? I know heat and a hammer are going to be answers, and i've tried both. There is no room between the lower bedside/fender area and the end of the bolt to get much leverage for the hammer. Looks like I'm going to have to find a sawzall blade that will cut through the hardened steel inner bushing so i can get through the bolt...

    ::sigh::

    Yes, I have sprayed them with liberal amounts numerous times...in fact, i think I've used a half a can on one side of the truck So frustrating...

    GOOD LUCK!

    I had problems when I did my shackle flip and then when I swapped springs. Even though you will eat up sawzall blades, (on the front spring bolts) I cut at the edge of the bushing and part way through the bolt, and used the 3/4" drive rachet to twist them off. Since you are using new bushings, you can drill holes through the rubber bushing to destroy it and beat/press it out easier.

    For the rears at the shackles, I cut the stock shackles in half so I could have more room to work on them.

    Re: Removing rear leaf spring bolts (Shackles/Bushings)

    I cut the bolt head off. then cut the nut off with a grinder and cut the hanger apart. problem solved. cut the shackles out to. there like cheap to buy and much less hassle then getting the bushings out.

    The fronts I got lucky and they came out. but a 4 1/2" disc a very thin cut off wheel might work just fine instead of a crappy sawzall and 20 blades

    Re: Removing rear leaf spring bolts (Shackles/Bushings)

    Cut the bolt head off, drive it out with a drift, and use fire or drill bits (or both) to get the old bushings out. Had to do this on my dad's old V1500, the original springs were just about welded to the truck with the amount of crap that was seized on.

    At least for the front bolts, you will need a little bigger wheel. Between the grinder body and disc, which wears out really quickly on the hardened bushing, I could only use the cut wheel for a very short period of time. It would wear enough that one could not reach what he needed to cut

    This is EXACTLY what I went through. On the first side, i was able to get about halfway through the bolt with the 4.5" cutoff wheel, but the hanger itself got in the way of the body of the grinder and wouldn't let me go any further...that's when i got the sawzall out.

    I have no idea how I'm going to get this other side off...Got one side of the front bolt cut out last night with just the sawzall, but the other side was being stubborn. It's shoved against the opposite side of the hanger and I'm afraid the sawzall is trying to cut through the inner bushing which is probably not going to happen.

    Good call on cutting the shackles in half...I could buy the ORD HD shackles, or the LMC catalog has stock ones for 70 bucks, and their office is literally 5 minutes from my work, so I could swing by there and grab them probably anytime.

    As far as cutting the bolt head off, i'm not sure how you all did that? There isn't much room to get much of anything where that bolt is, or maybe i wasn't looking hard enough. And driving it out with a drift???? The thing is seized into the inner sleeve, I don't see a drift doing anything other than making me cuss more than i already have

    Thanks for the responses though, I'm really glad I'm not alone here...what a pain in the ass, to say the least

    Quick tip: Never cease the sh1t out of the new bolts when you put them back in. Make life much easier down the road if plans change...

    I opted for ORD's greasable bushings, so i wouldn't have this problem...But yes, i may do that anyway

    ROYAL pain in the ass. I swear, if i worked at a shop and a customer came in wanting these leaf springs removed, i'd be charging 200+ an hour

    Re: Removing rear leaf spring bolts (Shackles/Bushings)

    I'm having fun with this same thing too. Broke a main leaf, decided to do both sides. One bolt came out, got my hopes up. Nothing else is budging (a week's worth of PB Blaster did get all the nuts off, but the bolts are seiezed in place).

    Angle grinder won't reach the bolt heads or between the hanger/springs. And I just destroyed 4 Sawzall blades (14T for steel). Those didn't get me even 1/4 of the way through 1 bolt! Off to the hardware stroe to try and find some grit-edge blades to hopefully get through this. Now I remember why the last few times I've changed springs I used the "blue tipped wrench". Really wish I had access to one of those now.....

    Carbide sawzall blade for the win!

    Man that was a pain in the arse, but new main leaves are in.

    Re: Removing rear leaf spring bolts (Shackles/Bushings)

    Fellas, I just finished this project...I'm telling you right now...Get a 7" angle grinder with a .045 cutoff wheel, and slide it between the spring and the hanger...Once I got the bigger angle grinder my springs were off in 10 minutes...I also fell into the trap of the 4" angle grinder not reaching high enough in the hanger to cut the bolt.

    A sawzall worked for some of them that i got started with the grinder, but I didn't try and start with the sawzall, I can't imagine a sawzall blade cutting through the hardened sleeve very well from the beginning...give it something to work with.

    That said, best of luck. This was by far the most frustrating and time consuming part of my 14bolt SF/Shackle Flip install...
