What the heck are you doing using a 1" impact? Is your Bronco built to earthmover specs or something? Use a 1/2" next time....plenty of power with a 1/2".:smilie_slapI also broke the threaded portion of the radius arm trying to remove that big nut on the frame rail - I was using a borrowed 1" Ingersoll Rand Impact gun that literally sheared the bolt right off. I got a used one from the junk yard for like $30 and it had a good bushing on it! My memory is a little hazy, but there is another booger of a big nut on the axle connection - I had to go buy a very large metric socket to fit and and also heat it with a torch before it would budge.
Did you use an O/A torch or just a small propane? If you get two flat sides of the nuts glowing red hot they come right off...i torched it the pb blaster then repeated that process many times still broke! its very rusty i will try to get the pic up. i am looking for a cheap used replacement first money is tight.
You need a large 1 1/8th in socket for the bottom bolt. Same size but really deep for the upper stud that holds the lower retainer that holds the lower spring coil. The rest is just lifting the vehicle & supporting it on a stand but make sure you put the jack stand some where other than under the axle housing so that when you un-bolt the spring you can stand on the hub to force the whole housing, rotor, knuckle, everything down so you can grab & pull the whole coil spring out. Don't worry there is no chance of it shooting out. Just step on the locking hub, against the brake rotor, grab it with both hands & pull hard. I just replaced mine with extended ones & was keeping the stockers for spares but if you're in a bind let me know! :thumbup-Kevin-It would be the left side. how do i take the old one off?
