Question about 1998 Jeep Cherokee
Let me guess... you want to change the pump because the pressure is low... Unfortunately, it's likely that unless you find a ton of debris on the pickup screen, changing the pump will do nothing for you. There is a 99% probability that your engine bearings have worn to the point that you are loosing more oil going around the bearings than is acceptable. This will also eventually affect the oil wiper rings on the pistons which are not designed to wipe that much oil from the cylinder walls. Once you have removed the pan, plastigage both rod and main bearings. Likely, you will find that you need a rebuild!
