Why do I need to replace lifters on my Jeep?
When I did the cylinder head R&R on my 4.0L Jeep engine I replaced all the lifters because I was getting a noise that is often identified as lifter tick, but it didn’t go away with the new parts. The engine’s been running just fine for the last year, and I’ve had it suggested that it’s just regular high-miles Jeep valvetrain noise.

Can you replace the lifter on a Jeep Cherokee?
The cylinder head MUST be removed. There is no way to cheat this, while yes, you can remove the camshaft without removing the head, by doing so, all the lifters will fall into the oil pan anyway which will now require head and oil pan removal. Pull the head, then remove the lifter. But replace ALL lifters while you’re in there…good luck.
