I have a 07 4dr Unlimited with 156,000 miles. The only thing I ever did to it was change the oil.

I just had a couple of questions. Of course when you take your vehicle in for an issue, they call you back with 50 others... It went in because it was rejected for inspection and needs a new cat and O2 sensor. (1800)

However, they called to tell me the damage when they checked it over at my request. ( Trying to get this thing to last me at least 250,000 miles, If not more) That the transmission needs to be serviced as there is also a computer update. (Okay. Whatever this means.) However I explained to them because the transmission had never been drained, but I did not want it drained in fear of the transmission breaking down a week later. They understood but suggested that I just have a transmission service instead of having it completely drained. I'm afraid to have the transmission even touch. Only because it's never been touched at 156,000 miles....

Thoughts and experience on this?

Also suggested that the 4 x 4 fluid be changed.

However at $250, I have never heard of the steering damper. I know my jeep is shaking, but I definitely need an alignment. Is replacing the steering damper for $250 even worth it?

Sorry for all the questions, just hoping to get some manly insights out there :)

Thanks so much

If by steering Dampner you mean the stabilizer that is there to keep the front end from "shaking" (looks like a small shock absorber mounted horizontally in front of the front axle) a good aftermarket replacement for one of those is about $30.
The labor to replace that would take a mechanic less than 5 minutes. Wouldn't even need to put it on the lift. Just be willing to get down and under the front and do it.

So.... that to me is a big red flag as far as what kind of deal you'll be getting from them. I would go eslewhere just based on that alone.

Yep.. Siri Isn't so great at spelling. I opted out of having that fixed until I get An alignment and then I will take it from there. Just wondering now about what to do with the transmission as I just told them not to fix anything but to replace the cat and sensor only... Thanks for your response

Some advice (it's free :).. If you want to go another 100k I would completely service the trans, including a fluid change. Not touching it because you never have and your luck is holding out, is not sound mechanical strategy. Fresh oil never hurts anything. Old oil never helps. That also goes for your differentials ("4x4 fluid"). 156,000 is a lot of miles and the best thing you can do to make it another 100,000 is to change your fluids at reasonable intervals. That doesn't necessarly need to be by the book but you shouldn't be going double the recommended intervals either.

If your getting some shake, you should have your alignment checked and also the wear and balance of your tires. At 156,ooo miles your steering stabilizer is probably shot and should be replaced (just not for $250).

Thanks Mark. I absolutely agree with you 100%. It always comes down with never knowing who to believe. Kind of like politics. I love my jeep and I'm definitely not shelling out 40 grand like I did the first time around when I purchased it brand-new, for another one..... With that said, it just seems like everyone I speak to either says because I never changed the transmission fluid before, that the gunk that Is going to get sucked out, may also be the gunk that is holding everything together :-/

Hence running the risk of the transmission completely failing on me.... With the 4 x 4 fluid change, I guess I should start understanding what the difference between the 4 x 4 fluid and the transmission fluid are, As when I asked for a price for a 4 x 4 flush, the guy quoted me as saying you mean a transmission flush? Meanwhile it's at the jeep dealership getting a new cat and sensor so we can at least go through inspection. I told them to forget the steering And transmission as of now, but perhaps I should call back and change that.

When I spoke to them they said you could either do a transmission flush or "drain". When I explained about my concern with actually flushing out the gunk that's holding it together, they said well if you "just drain" (Not flush) it's a completely different procedure.

My EH used to help me with all of these things...

But yes. A local shop when I asked what a 4 x 4 fluid change was he looked at me like I had six heads, And said, do you mean a transmission flush? but it is different then a transmission flush correct? Again. Thanks for your help

I'm no expert but i think by 4x4 fluid they are talking about the fluid in you rears or transfer case. Either way both should be changed. I have no experiance at all with autos since everything Ive owned since I first started driving is stick but I would still recomend changing it as well. However there is enough info on here to do most of this stuff your self and its always a good idea to learn how to do it. Tho that being said the transmission fluid usually requires you dropping the trans pan to do it properly but I could be wrong when it comes to jeeps since like I said Ive only owned sticks.

Changing the fluid in the diffs is a little harder and I haven't looked at it yet to see if you need to open them up but I'm guessing that you do. That can turn into a big job. The transfer case which is what im guessing they are calling 4x4 you can do on your own in less then 45 minutes.

As for the steering stabilizer it takes about 20 mins to change and depending on what quality or better put how heavy duty you want you can spend anywhere from 30 to 500 on them. I would recomend a fox 2.0 or something similer as they seem to have a good rep and will cost about 125$ and install is free if you have a 18mm wrench and a little elbow grease. Lot better then paying 250 for the stock piece of crap that I just broke last weekend doing a little off roading.

Hope this helps and good luck!!

I was assuming that by 4x4 you meant the front and rear differentials. Those are the gears that connect the drive shafts to the axles that make all 4 wheels go around. There is oil in there to lubricate those gears. Metal to metal wear (whether it's in a differential, a transmission or the engine) basically adds ground up metal to the oil and reduces it's lubricating capability over time. Whether that "gunk" does anything good (like holding stuff together) would be an interesting debate.
The old "if it's not broke, don't fix it" approch to things is understandable but, when it comes to working parts needing good clean lubrication, that's probably a good principal in all things... :whistling:

Definitely not flushing!!!!! I'm beginning to believe everyone was correct. I mean, they gain nothing to tell me otherwise. But here's something interesting a friend just sent me and it solidifies what everyone was recommending and that is not too. When you're there scroll down to the pink box.....

I think the only thing I'm going to touch is the 4 x 4 fluid case and not the transmission

changing diff fluid takes 20 minutes tops, you will need a pan, some gear oil, and a 3/8ths drive ratchet and some air freshener.

"4x4" oil is talking about your transfer case. 4x2 vehicles have a diff! you should change that, its all gears so no worries of it falling apart when the gunk comes out.

transmission is up to you. I will not make any statements regarding automatic transmissions. those things are brain surgery to me.

156k miles without changing fluids is way too much and asking for problems. Transmission fluid should be replaced at least every 90-100k miles if you want your transmission to last. Same for radiator fluid. Differential and transfer case oil should be replaced every 60k miles.

My reco is to change all the fluids (transmission, both differentials and transfer case, radiator). I would not do a "transmission service". The mechanic will be able to look at the drained fluids and judge if the amount of metal is OK or too much to justify additional maintenance.

Thanks for All the help. Yes. It should have been done prior, but since it's a question of changing or rather draining the transmission fluid "after" 150,000 miles is my concern. And most have said not to bother if it's never been done, As you could have major issues with the transmission completely breaking down. As far as the 4 x 4 transfer case, that I am having done.

$1800 for a new cat and O2 sensor? Did I read that right? WTF???
Yep :-/ sorry i aint a dude and can do it myself... Not aftermarket... Chrysler only has both cats that come assembled on the rod. All 3 dealers quoted the same price. It was 11 at some brake shop... I don't trust mechanics I would rather just take it to the dealer and have it done right and warranty.. Fml

Has nothing to do with you being nor not being a dude.

$1800 is f#cking ridiculous! :eek:


RockAuto for 2007 Jeep JK parts:

Cats: $467.79
http://www.rockauto.com/catalog/x,carcode,1433839,parttype,5808

O2 Sensors: Looks like there might be 3? Worse case is $180 for all 3, best case is $70.
http://www.rockauto.com/catalog/x,carcode,1433839,parttype,5132

With their 5% off coupon code it'd have been around $700 shipped. Add on $150-$200 for a muffler shop to weld the cats in and swap the O2 sensors and you'd have been done for under a grand, pretty close to what the brake shop said.

That's some expensive distrust! Daaaamn!

I would trust some mom and pop shop that could really suffer from not doing a job right over a dealership who could care less and probably has some 16 year old kid installing your parts.

I bet there is someone on the forum in your area that wouldnt mind making a few hundred bucks!

remember, you are a girl, so people on the internet will do anything for you. lol

But... it's her $$$. Too bad that's $700+ less for upgrades. I could really use two full sets of Rigid Dually D2 lights. :whistling:

Yeah, I think you really need to get a recommendation to a good local honest mechanic. Dealership charges are exorbitant and really only worth using if you need the warranty work. Check yelp, or ask around. A good shop will change all those fluids only make honest recommendations. Start creating the relationship now, so when you have something else go wrong down the road you instantly know where to go and who to trust. Don't get stuck letting a tow truck driver tow you to the dealer just because you don't know where else to go...
