Hey Guys,
I have always wanted to replace my body rubbers on my DD. They are dryrotted bad. I tried to get them off one time and couldnt figure out how they come off. Now, on my deisel project I got the whole body off and I still cant get the rubbers off! It appears they have a sleave that is attached to both outside washers locking them on the frame. Am I missing something?
I'll bump it up, but i have no idea. You should try looking for a frame off restoration for a Bronco or F-series of our date, there you'll probably find the info you want.
bolt goes thru frame, sleaves go thru rubber, rest on frame top and bottom, sleaves have rusted onto frame that's why they seem to be one part, penetrating oil and elbow grease.
After I took off the body, I threded one of the bolts in the nut from the top. Pounded on it with a 2# hammer. Hard to believe thats just rust. They arnt very rusty looking. I'll try the penetrant oil.
They are a real pita to get apart. I used a cutoff wheel and split the bottom washer on mine in a x pattern. I then pryed the washer off the rubber and sleeve. I did mine with the bodiy still on the truck while I was doing the lift. If you use a cutoff wheel be careful of the hot rubber flying and possible ignition of the old rubber. Try to cut as little of the rubber as possible.
I still dont understand exactlly how they are constructed. My best guess is the bottomnut is welded to the washer and a sleeve that goes through the bottm rubber. Then the top washer is welded to a sleeve that goes through the top rubber and the bottom sleeve. Then I'm guessing the two sleeves are rusted together. mine are not rusted to the frame. I can move and turn them in relationship to the frame, but not each other. God, that must have been hard working on the truck.
Yes i believe that the upper bushing had a sleeve that went down inside the lower sleeve and as you tightened them they sorta crush together locking them in place. I made my own centering sleeve from aluminum pipe at work and made my own large washers as well. I bought the red bushings from JBG. It was a pita working on it that way but at the time I didn't have access to a garage where I could you a hoist on the body.
Yes, they have interlocking sleeves. Depending on the amount of rust they can be a real bear to pop them apart. I usually thread the bolt back in (so you have full thread engagement to reduce damage), use an impact socket with extension to protect the head of the bolt, and use a 2.5 lb hammer to drive them apart.
