how to remove bolts from from leaf springs

In the process of removing stock leaf springs from 92 YJ. Having a heck of a time removing the bolts holding the rear of the front leaf spring. Do I just knock it out or does it thread into place. I got the nut of back side just cant get the bolt out.

Its probably rust welded to the metal sleeve inside the bushing.

Probably easiest to just cut the bolt to get it out with a sawzall or angle grinder (I prefer the grinder with a cutoff wheel)

It's not threaded in there. Hit it harder, give it lots of heat. Heck, sometimes it's easier to burn out the bushing and go with new hardware.

If you are installing new springs, don't bother with the bolt. Cut the head off if it's preventing you from getting the spring off of the hanger. You are looking for 4.5" grade 8 bolts, 9/16" for the frame side and 1/2" for the shackle side. Home Depot sometimes only has 4" and 5", neither is ideal. Look for a Fastenal in your neck of the woods. Best store ever.

If the bushing is dry rotted, drill into the rubber part of the bushing all around the inner metal sleeve. this will free up the metal sleeve inside and let you get th bolt out (assuming its rusted to the inner metal sleeve of the bushing)

cut off both ends of the bolt just inside the hanger, or close to the out side and spread it a little to get it out. The metal sleeve is rust welded to the bolt. use a right angle grinder. it will take forver with a hacksaw.

9/16 replacement

i used an impact gun to break the bolts free.. then hit it several times with a maul hammer on the backside of the bolt while still keeping it turning with the impact gun. Once the treads caught on the shackle the bolt backed right out... awkward but effective

The only luck I had removing the bolt was to drill out the rubber bushing. I found that the bolt was rust welded to the sleeve and the sleeve was rusty and expanded in the bushing making it impossible to get out with just a hammer. Drill all around the bushing and load it up with penetrating oil and it should come out with a hammer. You will definitely want to replace all of the hardware. Good Luck!

Need to keep track of this, I'm going to be doing the same myself and figured on cutting off the bolt heads but had no idea how tough they could be to get out (a maul? seriously?). Will probably drill out the bushing first and try it from there.

Agreed.
I've wasted way to may hours hammering and screwing around trying to get them out in the past.
Now if they don't come out after a few minutes I cut them off, remove the spring and drive the rust welded mess out of the bushing.

I had the exact same problem. I used a cut-off wheel on a 4.5 inch angle grinder to fit between the spring and the hanger, then it fell right out.

i just lifted my jeep friday and had this problem on one of them. i used a c-clamp type pusher that one one end was big enough for the head of the bold to push through. about 30 seconds with an impact gun and it was out

I had to drill the bushings on ALL of mine to get them out. Tractor Supply is also a good place to buy grade 8 CHEAP.

I had that problem on my 88. Spun it with an impact, and pried on it with a crowbar at the same time...finally came out.
