Its my first post on here so sorry if I get a few thi gs wrong
I just got my truck back from the shop and they said my radius arm bushings were shot, so I ordered in some polyurethane once from LMC and now I'm having a bit of trouble getting them on. The mechanic said I can replace them with a come-along, an impact wrench and a tree but I haven't found much else on how to get in there and replace them. If any of you guys have some input on how to get them off, it would be greatly appreciated.

There’s YouTube videos out there.
I just talked to a shop yesterday who will drill out the rivets, replace the bushings, and bolt it back up for $125 in labor. They’re going to be seeing my truck next week.

So you undo the big nut on the back end of the radius arms. Obviously you need to have the front end on Jacks. Then you can slide that side, including the axle beam, forward, which should slide the end of the radius arm out of its bushing and bracket. Replace the bushings and reinstall.

I've done it with a small sledge, beating on the end of the radius arm, but be careful not to damage any threads.

The come a long is just to help pull that side forward, out of the bushing and bracket.

radius arm and control arm bushings are different. radius arms bushing are under the engine cross member and control arm bushings are under the doors (roughly).
No... the radius arms are what extends back towards the doors. A bronco doesnt have control arms. The bushings on the engine cross member are the TT-beam pivot bushings.

Would I be about to pull out out manually or would I need the come a long too?

Yo 81 bullnose,
Welcome!
Bushing Replacement by Mrit @ Radius arm bushing replacement.
Excerpts;
"...Gotta unbolt the sway bar from the Frame on both sides. No way your gonna pull the axle forward without doing this.
Unbolt the shocks and lower the axle a bit. I didn't pay attention and lowered it too much. Hence the tight ass brake line. i got lucky and didn't bust it.
I forgot to take a pic, but you will need a large ratchet strap to pull the radius arms tight towards eachother. Mine would only move maybe 1/2", but that was enough. Then attach a small ratchet strap to the axle and then the furthest forward hole on the frame. The radius arm should pull relatively easy out of the bracket.
Prybar on the radius arm, and pull the bushing and washer off..."

Note, some use a come along

I busted out laughing reading this. That's one hell of an innuendo!

It may depend on how stuck they are. The ones I do this to in the junkyards are pretty stuck usually.

I really like that idea. I bought new radius arm bushings for when I was doing my axle pivot bushings, but really struggled with the radius arms. The old bushings were still nice fresh rubber, so I gave up on it and let them be. But, this is a great idea for when I return to them.
