I'm bout to go pull the 231 from my donor xj, any words of wisdom?

That's where I went and they gave me the one for idiot lights. So if it pegs to the right, it is ok?

So, you think the pump is ok?

I just pulled the valve cover off and it looked ok. It did have a little sludge but not to bad.

If you bought the one for the idiot light and your dash has the mechanical gauge to show pressure thab you need to go back and get the right on. You cannot use that sensor on yours as it is not designed to show pressure psi. Your engines most likely fine you just need the proper gauge for your application.

would a wheel bearing make more noise after letting off the accelerator? it makes noise while going but when i let off the gas it makes a grinding noise? and idk it sorta feels like it slows down.

DESERTXJ206

Yes, i drove mine with a bad wheel bearing for week since i didnt have the money to fix it. It got so bad you could hear it a mile away and feel it in the jeep. No matter on the gas or not thw bearings are still apinning in the hub since the wheels are turnin'.

XJGrason

thought so, is it a PITA to change both fronts? (might as well change both while im at it)

Great information, I checked a couple of these steps, I do have some bubbles comming up under the radiator cap, couldn't detect any cracks, I'll change oil and observe, send off for a sample test, I did determine that I have the 0630 head. Bummer I had planned on an expedition rack.

XJGrason

wait, isnt that the good head?

Well im not sure how the different years changed the hubs, but on my 90 you needed a 36 mm socket and a breaker bar. I actually broke the nut loose while the brakes and everything were still on. My wife held the brake and I used the bar to help with leverage. I believe the torque is over 150ft lbs on that center nut. Then i used a small breaker bar and i believe it was a e12 or e13 socket for the back 3 bolts on the hub. When i put everything back on i put some of that multi use greese on the axel shaft splines so it would be smooth going on or comin off if ever needed to repair. Took me about 1.5 hrs for one side when working slow and trying to figure out he best ways to do it. I could do it much faster after the fisrt one. Its better to do both at the same time but not absolutley needed.

thanks for the info, well ill probably do both because if they are the original they have almost 300k on them lol

bheath

I believe so. 0331 is the one ya wanna steer clear of.

DESERTXJ206

Good idea. Make sure you have all the tools and parts you need first. Check what size the 3 bolts are on the back of the hub. Im actually pretty sure they are a 13mm 12 point socket. Also a breaker bar and some anti seize for all the bolts is reccomended. Good luck.

I'm the idiot. I did buy the one for gauges and I have the gauge on the dash.
