98ZJ 4.0 Ironman4x4fab motor mount torque

Hi All,

Do I use the same torque for the Ironman4x4fab mounts as I would for the OEM mounts (80 ft.lbs from the FSM)? I ask because on the OEM mounts there is a large steel piece in the middle but not in the Ironman4x4fab ones.

I am having some vibration issues that I think are because my engine is not sitting square on the mounts. See the pictures below. I will be loosening and adjusting the mounts this weekend so wanted to confirm the torque numbers .

I don't know if this is true or not as I've never done engine mounts on these trucks but it looks like your motor mounts are installed on the wrong sides or backwards.

The engine mounts appear to have an angle built into the bushing housing that looks like it's opposite of how the mount on the engine is.

Again, I could be totally wrong on this though.

Also Ironman4x4fab.com shows a metal insert for the bolt to go through in their pictures.

yeah they cant be installed any other way due to the bolt patterns so I am pretty sure they are on right

The bolt does go through the sleve but if you compare the metal part on the ironman4x4fab mount to the metal part in the OEM shown in the pictures below you will see what I mean about more metal to torque down on in the OEM mounts. I am worried if I use the FSM 80 ft.lbs I am over torquing it.
