How to r&r cam bearings on a 98 Jeep Cherokee(xj) with a 4.0

Posted by on

    If your cam bearings have failed, generally there is far more wrong with the engine than just that.
    Likely it needs a total rebuild. On that engine you can't even begin to get near the bearings without taking over half the engine apart anyhow.

    There really isn't anything wrong with the engine in general. It has 280k miiles on it and I'm using it to tow a 5k lb travel trailer. The oil pressure drops low at idle, and I'm pulling the engine any way to replace the crank and rod bearings and the oil pump. So I figured that as long as I had the engine out, I'd also replace the cam, lifters ,and cam bearings

Since you are doing a rebuild, There is a tool made just for changing the cam bearings. If you are going into it that far, it is VERY worthwhile to have the block boiled and then replace the welsh plugs (freeze plugs) as well as the cam bearings. Jeep blocks tend to rust up inside the water jackets and accumulate crud in the oil passages.
As long as you are doing that, do it right!! Most machine shops charge very little to replace the cam bearings especially if they do the boil out for you. Unless you can rent or get the bearing tool cheaply, it's worth having that done.

    The only problem with taking the block to a machine shop, is that the closest shop is 2 hrs away. I've owned this vehicle since new and have changed the oil every 2500 miles, flushed the cooling system every two years, and changed tranny fluid and filter every 24000 miles. Eight months ago I took the head off for a valve job, and even the machine shop could'nt beleive how good it looked. I will be changing out the frost plugs, but most likely not have the block cooked. I watched a vidieo on cam bearing r

  • Richard Scordino Nov 05, 2010

    The end of your post isn't there. But, one tip ... Some cam bearings have a groove on the back side as well as an oil hole. It's best to put them in with the hole aligned with the port in the block. That way the oil passage can't become clogged and cause problems. Jeep engines tend to have internal rust problems. Once you get the plugs out, at the very least, run a garden hose through there to get anything that built up out. Also make sure there isn't any noticeable ridge at the top of the cylinder bores. That can break or damage the piston rings.

To avoid confusion, tag and remove the spark plug wires one at a time, for replacement.
If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes to reflect how your engine is wired.

Cherokee xj 98 skweeking noise under the middle center of jeep


All vehicles: squeak noise at center under car: likely a binding universal joint on either front or rear driveshaft. Also may give some body vibration at speed, often mistaken for out of balance tire. Stickshift cars: additionally noise can be from a bad clutch throwout bearing... generally also accompanied by vibration in clutch pedal when lightly depressed.
