Keeping it alive!

Hello everyone!

I have a 5.2L ZJ Jeep and recently bought it it just crossed over the 200,000 miles area. I don't have much of a history or anything on this Jeep and was wondering what are some things you all would recommend at this mile range to check on these?

I'm going to be replacing the exhaust gaskets this weekend, that looks fun ...

Probably looking at a CV soon too, any other things I might be on the look out for soon or I can replace now to avoid catastrophe later on?

Thanks for all the help in advance! I'm hoping to have a long life here.

Welcome to JeepForum

I would add an oil change to your list, if you aren't sure when it was last done. You could also do a tune up (plugs, wires, cap, rotor) for the sake of knowing they are brand new.

Probably not a horrible idea either! I forget simple things a lot of times! Haha

If it is burning oil, the plenum gasket is likely bad.
Check the transfer case for binding because at that mileage the VC might be bad too. (do figure 8's in a parking lot to check for binding).

BTW, Welcome to the forum!

So while I'm out doing figures 8's and having a blast, am I listening for popping? grinding? Or is it one of those things where I'll just know?

I know everywhere I park it I get a little tranny fluid on the ground, but it always seems topped off, does the x-case have it's own reservoir somewhere?

Couple things come to mind other than what was listed above. I am probably leaving a few things out too.

Change differential fluids
Change tranny fluid and filter
Coolant flush
New air filter
Check all bushings, including motor and tranny mounts
Grease all zerk fitings in suspension and drive shafts
While greasing, check condition of all boots on the tie rods
Check condition of ball joints
Check condition of wheel hubs

Edit: while you are doing the figure 8's listen for any tire squealing (unless you hit some paint), feel for any wheel hopping, or unusual clunks.

It will feel like it's binding up really bad and very wobbly. Probably leave black tire marks on the ground. For the plenum you need to pull the throttle body off of the intake and shine a really bright flash light in there all the way to the back. If its leaking you will see oil puddled up.

Its something where you'll just sorta know. I know the VC in mine is bad, and if I make a tight turn, it feels like the front end is trying to skip or hop.

It usually has to warm up a bit before it will do this correct? I never noticed that mine was bad until i drove three hours across state. Also, when I parked and turned off the Jeep, it would jerk forward because i was on a slight incline.

Depends on how worn out it is. Mine would do it right from the start.

You guys have given me a list to go through now! I'm pleasently surprised honestly.

This Jeep's future is going to be off-road and taking me and some friends back int othe woods to hunt (Ohio). I would like to be able to trust it in most weather conditions.

I've been driving it daily but I'm sure most of you are aware of where gas prices are now and I get about 13 mpg through traffic. I'm just a dealership parts guy, I'm not rich enough to drive it on my 75 mile daily commute haha.

Also, it's taking longer to start now than say 3-4 weeks ago, I hear lots of rumor about the crank position sensors going bad? Would this be somethign I can be proactive on? Sound like something normal?

If you haven't changed those sensors and want to be sure they are working it's a good idea to put some new ones in. Keep the old one's as spares just in case.

There are no exhaust gaskets at the manifold. I don't think the donut connection at the y-pipe uses gaskets either.
