Stuck Bushing Bolts.

[DeclansDaddy]

So I'm putting on my bracket drop lift and like the leaf spring bolts in the back, all 4 lower control arm bolts I'm the front are seized up in the bushing. I sprayed PB and multiple other lubricants but I feel they won't get all the way into the center of the bushing. I've tried heating and beating them with a sledge(can't get but so much leverage laying down) that didn't work so I went and borrowed an air hammer and that didn't budge a single one. Any advice aside from somehow going in-between the bushing and bracket with a grinder on both sides and just replacing the bushings? I'd hate to grind into the bracket some and weaken it.

Sawzall between the bushing and bracket normally does the trick.

That's what I was thinking, I just know how hard the bushing sleeves and bolts can be. Guess I better stock up on blades.

I burn them out with a butane/brazing torch. The oxy acetylene torch works too but a bit overkill. It gets really stinky but works pretty quick.

Well I ended up only having to do 2 bolts out of the 4 lower bushings. I tried the sawzall, I bought the Diablo blades per advice from the hardware guy and burned up 2 and I got a light and looked in there and it barely had nicked the bolt. So I ended up putting a 5-1/2" cutting wheel on my 4" angle grinder and maneuvering it around and getting them cut. The larger diameter wheel was the only way to get it in far enough to make it through the bolt.
