Tried the stud extractor, but no go. So off with the pan, and out the tube came. with my 5.5 inch lift, none of the others things per factory manual needed to be removed to clear the pan, but it was tight. upon install, I wrapped the dirty exhaust pipe with cardboard, as the pan does scrape the exhaust during install, and I didnt want that to cause the dirt to fall into the pan.
RockAuto sent me a new Mopar dip stick tube, but it fits my friends 2000 xj, mine is a1990, different dipstick design, so to make it work, had to remove a flare on the end of new tube, and file the outside diameter a bit to get the dip stick to fully seat and seal on the end of the tube. did a slight trim too, to assure my dipstick marks are in the same location relative to the block.
I assume the old style tube was superseded by the part I got.
my 1990 dip stick seals around the outside dia of its tube, and has a metal ring shaped handle. the 2000 dip stick seals with an internal oring, the handle is plastic, and is tee shaped.
why they changed the design I do not know, what a pain.
