98 4.0 trans mount replace..pic heavy

I was going to combine the trans and motor mounts but it was too long so I'll do them seperate. Disconnet the battery. Raise the trans a bit, just supporting it. I use a "v" block I had left over from the axle rebuild.

I had applied penetrant to the 4 15mm mount to crossmember bolts ahead of time. I loosened them up agood bit. I was going to pull the crossmember so I marked the edges to the frame as a reference. Pulling the crossmember also made it easier to get to the through bolt, but you dont't have to. I was worried a bit that the unibody frame might spring somehow but it didn't.

I applied penetrant to the 4 15mm member to frame bolts at holes in the frame. You'll notice that one of the member bolts on the right side has a slot in the member. This is so you can hang the member while installing or removing it.

I took the mount bolts all the way out and dropped the member. On to degreasing and painting. At this point the mount is still hung on the trans brackett.

Hit it with some self-etching primer and hung it on my redneck christmas tree and shot it with black epoxy enamel. The member has the word "front" embossed on it if you get confused when reinstalling it.

Ran out of pic posting room. While it was drying I removed the mount through bolt which is 18mm and the 3, 5/8in, trans brackett bolts. Took a wire brush to all the bolts. Sorry about the butt in the pic, but at least it wasn't a real one. The three brackett bolts had blue loctite on them, reapply it when installing. The mount was pretty compressed comparing it to the new one. The pipe bushing wasn't too bad but when the new exhaust goes in I'm glad its there. Install the trans brackett. Torque on the three bolts is 34 ft lbs. Install the mount, part number 5258485AB, to the brackett with the through bolt but don't tighten it yet. You'll notice the mopar mount has the word "front" embossed on it as well. Put a dab of antisieze on the 4 member bolts so you never have to worry about them rusting up in the frame again. Slide the crossmember in using the slot and install the 4 bolts semi tight. Install the 4 mount bolts but don't tighten all the way until the jack is out. Torque on those is 40 ft.lb. Adjust the member if needed to match your reference marks and torque the bolts. I couldn't find the value for the life of me so I just tightned them pretty good. Once the weight is off the jack tighten the 18mm through bolt to 48 ft.lb. and thats it.

X, I'm not sure. In the 96-98 parts breakdown they are only listing one, part number 52058765. The mounts are different as well as the trans brackett I believe.

Lol, no, the big one is left and I am in no hurry for that to happen. Trying to get that area ready when the big "M" happens.

Thanks newfie! That would be great since search is sometimes less than stellar.

Well, I hope the "m" isn't too soon! According to the steam I saw coming out of my vents this morning it may be one I'm dreading more than the "m".
