Like he said!.I've used a sawsall to cut the bolts between the spring eye and the hangar,then once the spring is out on the ground you can usually pound the remains of the bolt out--its pretty hard to get them out while its still in the truck.Another method is to grind the head of the bolt completely off,and put several washers under the nut,and tighten it with an impact wrench--you might have to remove the nut and add more washers if it bottoms out and runs out of threads.This will pull the bolt thru the bushing sleeve,usually they will spin right out once it breaks loose.An impact wrench works best for this,I have had limited success doing it with a breaker bar or other hand tools.The spring bushing bolts on most GM trucks are a big PITA to remove most of the time,due to them sticking in the metal sleeve in the bushings--wouldnt have been a problem if they werent so cheap--a little anti-seize goes a long way to prevent this!. /forums/images/graemlins/crazy.gif
