the jeep (00TJ, 4.0, nv3550) has 110k miles on it now and i have it torn down to replace the clutch. i have a little time to work on it now, so i am wondering how far down this maintenance/replacement road to go. the engine rear main seal is a no brainer, but i'm not sure where to draw the line, if i want to try to run down every single leak. it also looks like the head gasket is leaking, so that may be on the list too.
the exhaust is about done and i would really like to replace it, but if you have been following some of my other posts, i have been having issues with one of the cat/o2 sensors. i was considering replacing the whole thing, head to tail pipe, but the dual 'mini-cats' seem to be a deal breaker. it seems silly to me to replace the header and cat-back, but leave the old cats.
so far here is what i have definite 'to-do' list:
1-clutch kit (w/pilot and throw out bearing)
2-rear main seal
3-replace old driveline u-joints
4-replace all driveline fluids
i am also trying to think of other upgrade-type changes to make, like relocating the breather to a higher spot for water issues. (btw- i had read a really good write up on that but can't find it now).
so weigh in with your thoughts on what to add to the to-do list.
It is amazing what you can accomplish when you are too dumb to know that you can't!
