Aftermarket Bodymount question.

Hey all,

I have possibly a rookie question here. How much do poly bushings "squish" if at all under the weight of the body? I ask because my stock bushings are about 1/4" - 1/2" thick and the new bushings are exactly an inch. With the 1" body lift as well it looks like my Jeep may be lifted about 1.5" unless these new mounts squish down at all.

As far as the install, its going well but had to stop because of rain. All but 2 bolts loosened up with ease. The rear body mount bolts maybe had 5-10 lbs to loosen which I couldn't believe, removed them by hand easily. The two that are stuck are soaking in more PB buster and I am going about them, very carefully. They move but under a lot of torque.

I guess I'll find out.

Spoke too soon though as I have 1 body mount spinning. The front one under the grill. Andy advise on removing it is appreciated.

You should be able to reach up behind that one and hold the back side.

Where are the metal cups on the bottom of those bushings?

The front body bolt I cant seem to access from the rear, the front has an opening but cant get a wrench in there, maybe pliers? As far as the metal cups, most of these were so rusted that when i started turning the nuts everything just crumbled apart so for all I know they just rusted into oblivion.

So I got one side almost done. Front is still spinning and the rear crossmember was damaged before I bought the Jeep but never paid much attention to is at it didnt affect anything...until now.

Anyone have a suggestion about the crossmember, the bolts wont reach and it leaves this body mount/lift at a slight angle, my fix was to basically get a longer bolt, secure it and call it a day, I dont think it will be a problem other than maybe wear the bushing down faster.

It's torrential rain atm so stuck inside.

Probably not what you wanna hear, but I'd cut that rear crossmember out and replace it.

Might be a bit beyond my experience. Have never done chassis work or used a welder before. I might try a heavy duty C-clamp or try some more hammering.

Yeah, probably not a first weld job type project.

So this is fully installed. The front bolt can be accessed by removing the crossbar in front of the grill holding the breakline, to do this I had to remove the winch plate. So I removed the front bumper bolts and lifted the winch and the plate and propped it up on 2x4s. Pulled the crossbar and ultimately had to cut the nut. I cut the nut in half and pulled the top off then I cut the bolt underneath right above the rubber mount and pulled the two halves out. Replaced with new hardware and new nut and reinstalled the winch plate. With the body lift the cross member did not fit correctly and also caused my winch plate to not sit correctly so I kept it off and secured the brake lines to the bottom of the winchplate.

For the rear crossmember rather than trying to fix that bulge I pounded the plate up and once the hardware was lined up I lowered the body to put the weight on the mounts and then bolted it in.

I wasnt sure how much to torque evetything. The instructions says make them tight but dont crush the mounts but in order to crank them tight you kind of crush the mounts. Everything was torqued between 30-50 ft lbs. Hopefully thats ok.

A couple of notes, the body lift affected how the transmission changes gears in that the stick hits the tub for 2nd, 4th and so on. This will be fixed shortly once I due to the tummy tuck and get everything else in line.

Also ifnore the diamond plating and fender flares, I removed those once the body lift was installed, I plan to put on tub fenders, strip the body and repaint.
