Radial Arm Bushing Replacement
73 F-250
The bushings are gone. I have three rivets and two bolts on each side. I can easily grind down the rivets on the side but how about the one in the middle. I can't get a grinding wheel on it. Is an air chisel my only alternative?

All I did was unbolt the top of the shock and spring, Jack stands under frame with jack under Ibeam, let down the jack until spring is free then pull forward on the Ibeams until radius arm is free of mount. Change rubber and reverse.
Been awhile but I'm pretty sure that's about all, I know I did'nt cut out any rivits though.

Just like Clint said. It is no biggie, I did the bushings on my 91 Explorer Twin Traction beam about a month ago with no problems. You have to watch your brake lines tho. Remove your brake calipers and hang them out of the way with a piece of wire. I used a come-along to help pull the radius arms out of the bushings.

Radial Arm Bushing Replacement
I replaced my radius arm bushings on my 79 last winter. Wasn't too bad to unhook the radius arms, but the bushings were a pain to remove and I ended up burning mine off with a propane torch (talk about stinking up the garage)
Anyways, its not hard to do.. so good luck.

I did mine the lazy man's way. I heated up the nut so I could remove it. Jacked up the axle far enough to get a car ramp partially under the wheel (sloping down to the front). I slowly let the jack down and the wheel rolled foreward down the ramp until the radius arm came out of the hole.
Even though I didn't, I would recomend removing the shock, spring, and barke line.
Also, if you use a torch to heat up the nut, DON'T place the washer on the ground where you would place your forearm to crawl out from unter the truck. It will leave a mark (although it did come in handy when I wanted to show the parts guy what I needed to replace).
