Good morning… Trying to remove my rear springs from my truck to install my new Posies rear leaf springs. I cannot seem to figure out how the lower shackle bolt on the rear and the threaded bolt on the front of the spring…any advice would be greatly appreciated. Yep, one them broke of removing the top shackle bracket.
It appears to me that there is a pin driven into the double threaded bolt that's purpose is to keep it from backing out. I'd wire brush yours down and check for the pin
There was on the front two pins…I removed them and that pin wouldn’t budge…had to take an air hammer from the backside and drive it out…pins were corroded and deeply pitted. Still not making any headway on the back two…and I don’t have access to any major heat
Can’t get the shackle bolt loose…without using heat… don’t have any…what would you guys do to remove the threaded shackle bolt?
Go to the hardware store and buy a plumber's torch, they are always helpful to have in the garage. I don't remember if you can drive that sleave through that bracket or not, mine unscrewed.
Tried torching it with one…not budging. Don’t think it’s generating enough heat to help break it loose. Wonder if welding a nut on the end and trying that…any downfalls to that?
You would ruin the bolt, I would soak it with PB blaster a couple times a day then add more heat, that little torch should be enough.
If you're going to replace it all (bushing included), then I would cut off the back part of the stud, heat the casting with a torch and drive the whole stud/bushing towards the frame with a bfh. If you're just going to replace the stud, then heat the casting with a torch and try some candle wax into the threads. Then a pipe wrench and cheater bar.
I would think the propane or MAP gas would be enough. If not you should be able to rent an oxy acetylene torch with a rose bud tip from an equipment rental outfit. I've always used Liquid Wrench for penetrating fluid. Last resort option is to clamp a steel plate to the frame and use a mag base drill and drill it out to the minor pitch diameter for that thread and then carefully re-tap it. If you drill out the stud the air hammer with some heat may be able to drive out the sleeve.
These are the shackles I bought from Posies to use with there springs…looks like I don’t use the threaded bolt or sleeve…
Did you try counter clockwise by chance ? If worse comes to worse you could remove the bracket off the frame and take it somewhere with a bigger torch.
I'm probably wrong since I've never touched a pick up but bare with me. @57tailgater posting #9 link of shop manual has me thinking. Are you sure the shackles are the correct units for your truck tonnage wise???
I have to no avail…noticed you installed I believe Posies on the rear of your Chevy…did you use their shackles like the ones I posted in post 16?
Well…the truck is supposed to be a 100… so that’s what I went with when I ordered from Posies. These are the shackles that they recommend to be used with their 3 inch dropped springs. I just did what 1oldtimer suggested and cut the back half of the bolt off and drove them both out towards the frame. Took like five minutes and I am embarrassed that I didn’t think off that myself. I certainly appreciate everybody taking the time to offer suggestions and advice. Gonna clean everything up and paint the back half of the frame, brackets, and springs and put everything back together.
As you can see in the kit shown above, there's a sleeve that's internally threaded for the shackle bolt. So you can remove the entire sleeve if the shackle bolt is stuck. I've found that lack of lubrication is usually why they're stuck, and sometimes applying heat and then putting grease into the bolt will free the threads up. If they wont take grease get yourself an impact grease tool that you fill with grease and then hit it with a hammer to force grease into frozen fittings. They'll almost always get the grease into the fitting.
Hey all! Revamping this old thread with basically the same question. I'm trying to remove the FRONT pin from my rear leaf spring mounts on my '59 GMC 100. It appears to be the same as this photo. I already got the small retainer pins out. Am I driving the larger pin inward (towards the center of the frame (red arrow)), or outward (towards the outside of the vehicle (blue arrow))? In either case, with my stepside bed, I am extremely limited on clearance, either for a persuasion device, or for the pin to be fully removed. I've got a torch so I'll probably go to town with that. Any advice is greatly appreciated.
Now THIS is the picture I’ve been searching for for two weeks. Thank you!! Now I can at least hammer in the correct direction.
