    Installing sport spring!

    Errrrrrrr..... 😡 Im replacing the stock leaf spring with a sport spring. I've got the old leaf spring loose with the tension off of it. I've got the passenger side lower A arm down but the drivers side must be possessed. The two bolts that hold the lower A arm to the cross member will not budge. I have the nuts off. I've used heat, beat on it, prayed, you name, I've tried it... it's like it's welded on! Any suggestions?

    Since you said you "have the nuts off" I guess you're meaning the vertical bolts that pass through the cast iron thingy. I presume that your bolts go in from the bottom and the nuts were on top. If that's the way they were, then I can't imagine what could possibly still be holding the lower A-arm to the cross member:

    Front suspension install completed (1).jpg

    The crossmember is only 1/8" thick, there shouldn't be anything except a little rust holding the cast iron piece to the crossmember and the bolts sticking out the top.

    Unless some ding-dong put the bolts in from the top and they're rusted solid to the cast iron.

    Then yer screwed and you'll have to sell the car.







    Try smacking the head of the bolt(assuming it's on the bottom) with a sledge hammer. Bolts pull upwards against the threads of the nutting or bolt hole. It sounds counter-intuitive that hitting an already tight bolt like a nail would do anything, but the trick does work. It fractures the crystalization of the rust. Those bolts are super heavy duty hardened steel, by the way. Put a big ole pipe on the end of your wrench and yank on that baby. If the bolt snaps, OGTS offers new ones. Or Harold can dig through the chicken poop and fetch ya some from his barn.

    Well, some ding dong ran the bolts from the top. The bolts are simply part of the cast iron thingy now! I've started drilling the bolts out from the bottom and that's a pain in the ole butt.... I'm assuming the bolts are probably grade 8 or better... I'll keep you posted...

    I my opinion you should not worry......just burn off the top of the bolt head with cutting torch and it will be free...
    Then worry about getting them out of the cast thingy

    Have you seen where the bolts are on the drivers side? I'm not sure a cutting torch is the way to go... I'll get this thing. It's not going to whip my a$$!

    Everybody has his own recipe how to free rusted bolts. I have great experience with 50:50 Acetone/ATF mix. Soak those bolts generously and leave it overnight.
    On the subject of sport spring, use intermediate one, 2” lowering spring is way too hard for a street use.

    Have you tried getting an impact wrench on them at low power with a flex or u-joint attachement? If you spin them they may free up. Or double nut it on the bottom and turn it with a wrench.

    Forget the drilling. Drop the front suspension so that you can get those bolts out properly. You'll spend way more time and cuss words trying to get them out on the car.

    I would drop the suspension as suggested. You are going to have to do a PERFECT job drilling them out and that is almost impossible for such a long bolt, but you are into it now. If you go off center you will cut into the cast steel part because the bolt is so hard.

    That's where this is heading! I've installed these springs before, while the suspension was in the car and with it out. Never had much of a problem before. One side came out great. But, nooooooooo, the other side is filled with hate and Satin.

    If you only screwed off one side, didn't you have to trim the rubber bushings off on the old spring to get it to slide through? That might work....

    I'm thinking the same thing as Norbert. You should be able to swap out the spring with just one arm detached.
