flywheel (Flex plate)

has anybody had problems with their flywheel or ever changed one on a 4.0?

Changing a flywheel on a 4.0 isn't a problem ... after you get the transmission off. there is only 6 bolts that hold it on.

What problems are you having?

Just guessing but can't get the new one on? Six bolts but only going on in the right orientation, bolt holes not all equally spaced.

i took the starter off and can move the flywheel with my hand.

Sounds like your flywheel (or "flexplate") has busted out where it bolts to the crank.

yep, thats what it sounds like, cracked casting in the center of the flywheel.

but the torqe conv and fly wheel will not come off, and the t.c is stil bolted to the flexplate.

The center of the flexplate bolts to the crankshaft; that's where they commonly break.

Actually mid-year 1997-up it has EIGHT flywheel bolts with E-torx heads.
