Rusty ass old leaf spring removal questions...

So I've got rusty leaf spring bolts, and I need to remove the stock springs. Anyone have any tricks on getting the bolts to slide out of the old bushings? i've had a hell of a time trying to do this before. Hammering, heating, swearing, etc. I'd like to do it quickly this time. =p By the way, I've been soaking the crap in PB blaster since I noticed the broken leaf spring that I mistook for 10 bolt itis. Any suggestions would be appreciated.

Look at 'em real hard and tell 'em "I'm Rick James, bitch!.. tha fuck out my spraaaangs!!!'

hehe Ok seriously now-- you are not going to get them out. Cut them off, beat the long end out with another bolt. HOPEFULLY they aren't rusted to the bushing sleeves. IF they are, you get to take the spring to the press and press the bushing out, or burn them out with a torch.

Have fun.

PB Blaster and drive them out with an air hammer.

or
If there's not enough room to drive them through, grind or cut off the bolt head and try going the other way.

or
Use a Sawzall to cut the bolt inbetween the bushing and the shackle/spring hanger on both sides. Once you get the spring out, use a press to push the bushing out.

You were not hammering hard enough.

Good advice, air hammer is your friend. If you don't have or can't borrow one from a friend, rent one. Just make sure you get an attachment that will work for you

I have done many. You could beat yourself sensless with a hammer, but the air hammer does the trick 90% of the time. So just backing up what was said before, it works.

I took an impact to a couple of rusty spring bolts once. They broke right loose and I was able to spin them the rest of the way out with the impact or tap them out with a hammer afterwards.

Awesome, I'm going to have to look into renting an air hammer. It's on a tahoe, so the gas tank is right there and all, air tools would probably make it much easier.

If you don't have and impact, I would spend my money there. It is way more handy than an air hammer.

I haven't started purchasing air tools for the house yet. I went with scoring welding stuff first, so I do have a torch I can use for this. I think the impact may be the key to this, because I really can't spin the ratchet fast enough to get the bolt to work free from the bushing. I may go over to united rentals and pick up an electric impact. That would probably be a serious help on getting the U-bolt nuts off as well. I'd rather not have to cut this stuff off, I'm trying to fix all the stuff that's wrong on the truck before I start to build anything.

Or just nut up and drop $100 on a home depot electric impact.

Jeezus christ.
I usually take the bolt off and soak them in pb blaster go th the other side repeat and give it a GOOD WACK put some balls behind it. It will come out. And the rears I used a box end wrench and a ratchit. I wouldn't use electric impact because they will out do your wifes tool's. I would just man up. Should work just fine. How did people survive with out the internet?

Are you going to ask how to get the new ones in next?

I have had no luck with a few. One bolt on my front spring shackle was frozen in place. Solid.

So I just used my angle grinder and cut the bolt on both sides of the spring.

I have a $60 electric impact from northern tool and love it. Sure It doesn't hammer things to 400 pounds, but it makes life a hell of a lot easier and can put enough torque on most any bolt to break it loose.

I have used air impacts in dealerships and yes, they are levels and levels above a cheap electric, but for my it saves hours of wrenching time.

i usually end up just cutting them off and then trying to hit them with a big punch and hammer while in the vise. if worse comes to worse i just buy new bushings. there are springs shops all over out here

Well, spent the afternoon parts fetching. Picked up a used milwaukee electric impact at a pawn shop for $70. Seems to work and doesn't smell like electrical fire when you run it, so I'm going to give it a whack tomorrow. The only thing I'm short is a new set of U-bolts and nuts, I'm flipping the u-bolts at the same time. Hosed everything down with the PB again, hopefully it won't be too much of a cunt. The ones that had me stuck were the front bushing mounts, we shall see this time.

Thanks for the help so far.

Use a sawzall on the bolt between the hanger and spring don't need to go all the way through only a little if the are frozen, then put a wrench on it and put some ass behind it and snap the bolt off where you scarred it with the sawzall thats what we do in the rust belt known as the northeast if, it don't come out break it off.

Wound up getting everything handled ok. Picked up a milwaukee impact for $70, although it didn't really do too much other than the wheel lugs on this one, I can see it being useful in the future. I wound up doing the first leaf in about 2 hours, the second one in an hour and a half or so. Picked up 5" metal cut off wheels from home depot, threw them on the angle grinder and was able to chop through the front hanger bolt on each side in about 2 minutes. I wound up taking the torch to the shackles on both sides, cutting it off right above the bushing in the lower mount and removing the spring to give me some working room. With the shackles cut off and the spring out of the way, it was super easy to get the angle grinder in and chop the bolt with the little piece of shackle in it right off. I took both springs to Atlas Spring in La Puente, where they pressed out the old junk shit bushings, and supplied me with Ubolts, throughbolts, and new shackles for a very reasonable price. I used 5/8"x9"x3" u-bolts through some old 1-ton spring plates that I had in the garage. I scored a set of energy suspension PU bushings from Craigslist for $25 and installed those in the leaves on both sides. I left the rubber bushings in the shackles because I figured it'd be a little more towards absorbing road vibes. Got both leaves replaced, now the rear end doesn't feel like it's unloading when I hit the gas. Hit a few big bumps near the house, and she held together and felt significantly better. The fucking rear still clunks all the time, but it's a 10-bolt for now and all of the 2 door tahoes clunk like a mother. Whatever. I left the u-bolts an inch and a half long in case I want to run an add a leaf in the near future. If I don't wind up putting one in pretty soon, I'll just cut em off.








Here's a few pics:

Talking Hmm you been takin my pictures of me?

Damn odd but thats looks like what i did all weekend,
Cut the bolt and sleeve inbetween the spring and shackle then grind the head off and pushed shackle sideways and plip

In the second or third picture it looks like your shackle hangers smashed in to much and squishing your shackle bushing might want to put a washer or two in there.


And dont ask me how but fix your brakes and the clunk will go away if its when you shift through the gears sittin still,.........but then your transmission will burn up in a few weeks, and the good old gov bombs gunna blow right after that.

O and have a nice day!http://www.pirate4x4.com/forum/image.../thefinger.gif
