Cab bushings
Finally have gotten around to replacing the rubber bushings for the cab and have a question for anyone who has done it. I used the search feature and brings up a gazillion posts but I havent found one specifically dealing with my question. Can I just jack the cab up with everything mounted and replace the bushings? Are there any things I should loosen before I raise the cab such as fenders, linkages etc? I'm thinking I wont have to jack it much to do this but just wondering. Going to have to remove the in cab tank to do the rear mounts looks like.

i dont see why you couldnt just lift it alittle bit to slide the new one in.

I couldn't get my original bushing to come apart, you are supposed to hammer them apart...or atleast try to that is. I ended up jacking the cab up a little bit, cutting them apart with a sawzaw and then making new bushing supports.

It took a punch and a 20lb sledge to get all my mounts off my 77's frame. Where did you get your bushings? and are you reusing the hardware

make sure you unhook the steering column at the rag joint or you will ruin it. I found out the hard way.

When I replaced my bushings, I replaced both the bushings and the mounts. It was the easiest way I saw of doing it since my mounts were pretty much shot anyways. I got a set of these and drilled the mounts out from the bottom.
High Speed Steel Step Drills & Other Step Drill Bits - Harbor Freight Tools It made it extremely easy to remove the old mounts. Here were my steps 1) Drill out old mount from bottom 2) Jack up fram using a 2 x 4 about an inch higher than the new mount. 3) Place new mount. 4) Bolt it down. I didn't have to remove or loosen anything. As mentioned I watched my rag joint but since I only jacked up an inch or two no damage was done. I got new mounts from Jeff's bronco graveyard and poly bushings. |

Correct, I removed the bolts holding the "body mount sleeves" together. The body mount sleeves are the part with the mushrooming heads that compress and hold the bushings in place. Before I choose to drill them out I tried everything I could to get them out, including a punch and 20lb sledge, heat, PB blaster, etc. Mine would not budge and for the ones on the core support and front of the cab getting a sledge in was impossible. I got a kit that had all new sleeves (6) 12 pcs total. I got new grade 8 bolts as well. I figured if I was going to do it I didn't want to do it again. I removed the bolt holding the sleeves together and drilled them out from the bottom. For most of them the bottom mushroom head broke free and I slid off the bottom bushing and slit the rest out from the top. I then replaced bushings and sleeves and bolted it back together. This was 2 years ago now and I have had no problems and a lot less noise.

Ok, so these are tougher than I hoped so I ordered new bolts and sleeve/washers. Question, when I jack up the cab, which when I say jack it up, I mean just enough to slide old stuff out, new in, do I need to unbolt the front clip anywhere such as the inner fender support? I dont want to warp anything.

I don't remember loosening anything other than the mount I was working on. I would just take my time and listen as I jacked up the body.
