  • Body mount repair?

    Afte finally using the sawzall to remove the old body mount bolts, it seems that maybe three of the middle ones have some issues. Is a good "monster" washer welded in going to be strong enough? The side parts of the"U" mounts appear to be solid, not totally sure if the whole top plate needs replaced or not yet. Just wondered if anyone had gone this cheapo route before.

    Worked for me...

    I just did a YJ tub swap to my 84 CJ7. The holes through my side mounts were also slightly larger than they were supposed to be. I picked up some large heavy duty washers from my local jeep shop and I had them welded in. The bushings fit tightly into the washers so I had to line them up just right prior to welding so be careful! Have fun!

      I did the same thing, welded on some heavy washers. Had the Jeep on the road and trails since August, and no problems at all. The washers I used were thicker than the body mount metal. Good Luck, H.B.

        Cool. Soon as the body mount bushings show up, I'll take one the the store and snag some up. Thanks.

          i welded 1/8 inch pieces that where the same size as the top of the body mount. then i took a hole saw and from underneath drilled them to the same size as the old hole. i thought about the washer route, but i had the hole saw and some steel laying around. i think it may be a stronger fix anyhow.

            I kinda have "access" to enough plate to do that (left-overs in the ag shop), but was gonna give the mounts the screwdriver test first, to see if washers would be enough. If the whole top part is shot, I'm going with the plate.

              Got one more question (imagine that)- one of the rear body mount bolt heads rusted off, leaving the bolt sticking out of the body, resembling a stud. Any ideas on fixing that situation?

                Soak with WD40 or something like that for a long time. Weeks if can. Then used a little force, if that doesn't work then use a little heat.

                  Well, just got done putting on another can of undercoating and got to looking at this little problem. The plate it's attached to inside that little boxed in spot is not really attached to the jeep. Looks like I'm gonna have some fun fixing this. May have to use the acetylene saw.

                    anybody know where theres a site or a page devoted to tub swaps? Seems like I've found one for everything else (that 4.0 head on a 4.2 was a good one) I might be buying a 78 that has bad mounts, need to know if it needs a full tub, if I can just replace the mounts and one floor pan, and how big of a job a tub is. What to look out for when changing a tub. I have installed a bunch of body lifts and built a couple full size Chevys frame up, but I'm pretty novice when it comes to Jeeps.

                    PS try PB Blaster, works way better than WD-40 or anything else I've ever tried.

                      So far it seems like the tub swap is not that hard, BUT- mine isn't on yet, I'm not swapping the tailgate, my mounts are pretty bad(some), I'm not sure if the hole for the clutch rod is in the right place(I did measure three times).
                      Several apparently minor issues, nothing major. There's this dude, calls himself "jeepskate" that has a page or ten on this. Just google "YJ tub swap" and start reading.
                      I got some PB left- bought 3 cans for this project.

                          It's the left rear- the one that goes through the crossmember. It does actually look like a stud- I'll check again to make sure it's not just a stripped bolt. Either way, I think it has to come out.

                            Been there, done that

                            You can "peel" back the little box that houses the nutsert at the back of the bolt. I cut the welded areas with a sawzall and peeled it back enough to get something in there to hold the nutsert. You can even just pull the whole thing out from the back if you open it up enough. Good luck!

                              Well, after several rounds of heat and pb, guess what?
                              Snapped right off. So, will now try to open that box up from the back, probably pull that thing out and replace with a plate and welded nut.
                              Wish I hadn't forgot that before I trucked the tub home- got no decent tool in my garage.
