Do I need to replace the flywheel?

T90/D18 combination isn't too difficult. I removed the transmission floor cover to expose the bell housing bolts, used an engine hoist with a strap through the exposed opening in the floor, and lowered it down to a creeper to pull out from under the Jeep. Removing the cross member, skid plate and shift cane before dropping it helps and is simple to do. I also put the rear of the Jeep up on jack stands to give me a little more clearance underneath.

If you don't have an engine hoist but access to an ATV jack it's probably even easier.

i just went through this, I dropped the tranny/xfer down with a come-along. I've done it with a floor jack before but I find the winch is easier.

I found it easier to put it all back one piece at a time.

Or you can pull the transfer case off the transmission by hand, then pull the transmission, by hand. No jacks or straps needed. This is an option if you don't have a transmission jack.

 

I have found it easiest to remove and replace the whole assembly at once. Bellhousing, transmission, t-case and crossmember with skid plate still attached using a good floor jack. The skid plate is easy to wiggle around on top of the pad of the floor jack plus you can roll the jack a little too. It just takes a bit of caution to balance it but no matter what you do you have to be cautious anyway, and this saves having to pull the t-case. Just pull the top off of the transmission and the t-case shifters for clearance.

 

I agree. I was just suggesting the other approach if the OP didn't have a jack.

 

No doubt without a floor jack that would be way too much to try to manhandle.
