Buying a 2005 WK Hemi tomorrow, ?s on a few things.

Hi everyone!

Tomorrow I'm buying a 2005 WK Hemi tomorrow and I plan to swap all the fluids (except the tranny fluid, that still looks great) and I had a couple of questions.

I found this gasket - Can I use this on the rear diff or front?
http://amzn.to/1Vcp45o

As for coolant, I use Zerex in my G6 and I've been very happy with it. I was looking and they have a G-05 formula, can I use this?

I've already ordered all new LEDs for the interior, anything else I should take a look at? I'm buying the Jeep from my father, he's owned it since it was new on the lot so it's been well cared for (mostly) but it's getting up there in miles, 82k, so I'd like to do some preventative maintenance. I've been reading nearly non-stop the last two days trying to avoid asking too many questions that I could find answers to.

Last question: If you could go back and pick your first mod, what would it be? (Thinking, I should have done this sooner!)

Re: Buying a 2005 WK Hemi tomorrow, ?s on a few things.

seems like most of the guys pump out their front and rear diffs rather than pulling that plate off and trying to use RTV to make a new seal. That gasket looks cool though and it has great reviews on Amazon... Unusual to see something with only 4 and 5 star ratings.

Check here for coolant specs. - Jeep Grand Cherokee WK - Maintenance information and schedules
I don't have any experience other than factory coolant. I also believe they do not recommend flushing (with pressure) the cooling system. Don't quote me on that...

82k on a 2005 is low miles! a well-maintained Jeep can last...

Check for a transmission line coolant leak... the fitting under the oil drain channel for the oil filter seems to be a common issue. I believe that oil drips during a filter change causes that fitting to fail prematurely.

Mods... LEDs are fun... billet antenna. upgrade the audio system and replace that factory unit so you can get some of the more modern conveniences..

Re: Buying a 2005 WK Hemi tomorrow, ?s on a few things.

I was tempted to pump it out too but it's never been changed so I want to make sure I get everything out and don't leave any remaining cruddy oil in there. Transfer case fluid hasn't been changed ever either. Very tempted to buy the gasket, maybe I'll pick it up and some RTV as backup.

Thanks for that link, I've gone over so many over the last few days it's hard to keep track of everything.

It is, the maintenance hasn't been upkept really outside of the standard oil changes (though not diff changes) so I'll be doing that on my own. It's been garage kept it's whole life though, so that's a plus! There is some rust underneath but I don't think there is a single car up north that doesn't have some rust on the undercarriage. I think my biggest issue each time I change things will be the skid plates. That and getting all four corners up in the air, I almost never do that with my other vehicles. ( That and my garage doesn't give me as much height as I would like)


I think the only thing I would upgrade with the audio system would be the speakers, if that. It doesn't sound bad and can play MP3 cds. The only thing that would really make or break it would be the ability to add AUX, which I'm surprised wasn't included.

Re: Buying a 2005 WK Hemi tomorrow, ?s on a few things.

Yeah, I just like using my phone to play my music. It seems once I had that ability, I stopped using CDs, terrestrial and satellite radio.

Has the transmission fluid been changed? It calls for that at 60k. http://www.wkjeeps.com/misc/maintenance_schedule_wk.pdf It looks like a headache to do.

I tend to follow the recommendations from the factory on most everything. If it's only had oil changes, it'd be worth it to do the plugs, PCV valve, transmission, and the cabin air filter. Along with everything else you're planning on...

I ran across the TSB I was thinking of on system flushing. It looks like the cooling system can be flushed with appropriate system flush. Here's the TSB.

Interior LEDs done! All of the light you see is made from the LEDs, nothing else. I'm pretty pleased with them. I wish the back was a bit brighter but only having one bulb makes that difficult without custom installing some.


Tranny fluid hasn't been done either. I plan to eventually get that taken care of plus buy a lifetime alignment and get that done. The tranny fluid is still pink so I'm not too worried about it.

Getting the diffs and the transfer case changed out are my two top priorities right now.

@Dextar - if you come back to this thread, I'd be curious to hear your experience with the lube locker gasket. I did some research after you mentioned it and heard both good and bad on them.

Re: Buying a 2005 WK Hemi tomorrow, ?s on a few things.

I'm still here, I didn't end up buying the gasket though. I'm not sure that I'm going to take the whole cover off yet. It's not something I have ever done before and it makes me nervous to mess something up. I'm likely going to buy a pump and suck all of the fluid out then just re-add it.

Re: Buying a 2005 WK Hemi tomorrow, ?s on a few things.

Yeah, I hear you. I'm at 85k and I ordered the fluid to do mine as well.

Here's a good post on the site for removing/reinstalling the cover. How To: Change Differential (Axle) Fluid

But the pump and refill method is attractive and low-risk. And pumping/refilling is better than nothing... I'll probably pump and refill mine also.

Hows your transmission fluid look on a white paper towel? Also, how does the serpentine belt look?

Both of those look great, pink on towelling and no cracks. The engine was fully rebuilt, I should check to see if they replaced the serpentine belt when they rebuilt it.

Re: Buying a 2005 WK Hemi tomorrow, ?s on a few things.

Guys, you need to remove the diff cover, drain the fluid, and clean out the insides. Sucking it out leaves the dirt in there, which is what wears the bearings. Better than nothing is not how to maintain properly, and a bearing kit installed is about $1200. The trans fluid is god for 100k, so no need to change it before then. The TB will be gunked up badly unless there is a catch can installed. Remove and clean it up like new, (rubbing alcohol, not carb cleaner, and use soft towel). Undo the battry neg termina hile cleaing to reset the ECU, as it will not idle properly with the clean TB and will throw a code. then put a catch can on as your first upgrade to keep it clean. I would also put Seafoam in the oil just before the next oil change, run it for 150 miles and it frees up the sticking MDS lifters, makng it drive much better and quieter. Put Seafoam in the gas tank also to clean injectors. I use it every 15k and the Hemi runs beautifully with 120k.

I hear you on the rear diff... it makes sense to get it as clean as you can. I'm just puzzled why the front diff has a drain plug but the rear doesn't.

On the throttle body, yep. Everything points to cleaning it... it's just a bit of a daunting task as all the documentation says it's not serviceable. And there's some folks on the fora that cleaned their throttle body and ended up at the dealer for a replacement. It does seem that Chrysler solved a hardware problem with software on the throttle body... clearly a clean TB is better than a filthy one....

And on the trans fluid, I'd go with the schedule B, and change every 60k.
