2002 Jeep Wrangler appears the rear of the oil pan gasket is leaking. How hard is it to change out and any tips/ 2001 jeep wrangler something leaking inside back wheel is it the rear seal

we are not them, this is just public forum.....
what if it's was not the gasket, and the oil seal rear leaks.
or trans leaks.
is car opted with,,, a trans A/T or M/T (auto/stick?)
is the oil leaking (sniff sniff/ look)
engine oil (use engine dye to see it)
ATF (red) or GL3 (manual gear lub)
first is to make sure which lube is leaking, then fix that.
sealing pay, is 3 things, good gasket, good sealant, and skill putting it on (and letting the sealant cure per lable)

rear main oil seal

check fluid level. if low it will shift hard. also fix leak. could be a pan gasket or a cracked housing

Go to http://www.jeep.com/en/owners/manuals/index.html download your free service manual that will give you a step by step instruction on removing and installing a new oil pan and gasket.

can't really go wrong with synthetic oil as long as the grade and weight of the oil is equivelent to what is in there now.

On most, you need to remove all bolts around the perimeter of the pan, (You may want to remove starter to get to fasteners there) then slide a paint scraper between the pan and block to break the seal. Generally there is enough room to get the pan out. If you need a bit more room, support the transmission with a jack (use a piece of plywood on top to avoid bending anything) remove both engine mount through bolts and raise engine slightly (not too much or you will break something)

All the Way around on all 4 Sides. Make sure that there are no gaps in between

You need to Put Blue ATV Silicone on Both sides of the Gasket to get it to Seal Properly. This is a High Temp Sealant and Once Set it will fix the Problem.

It is the oil pan gasket all you have to do is drop the oil pan clean the bottom of the engine block and the surface of the oil pan and install the oil pan again. a very simple process. Make sure that it is not the rear main crank seal that is leaking. If it is the rear main then you will have to remove the tranny to replace the rear main seal.
