I took my whip in to Jeep yesterday because my window broke. And they did a inspection on what should be done soon. Curently Iam at 23813 miles. They said by 30k I need to do a few things. On the list they include Trans. Service (139.95), 4x4 Service (489.95), FI Decarb Service (199.95) and air filter (35.79). As for the Air filter I can take care of that no questions asked. That trans service I would asuume to just be changing the fluid right? How hard is this and how much would it cost me to get the fluids needed? I'm no mechanic but I have done a full motor swap on a car before so fluids are nothing to me I just never worked on the Jeep before. Next is the 4x4 service. Iam thinking this is the differential fluids correct? Again how easy how much? FI Decab Service? Iam thinking this is just cleaning the Fuel Injectors? If this can get a lil better gas milage I would consider it, if its somthing that I can do myself then I would rather go that route, but would like some input. Let me know what all you KJ Pros think about my future plans to keep her running longer?

Dang give us time to get home from work.

Trans service Yes, lets them or a lube shop do the flush.
4WD service is just changing the fluid in the Diffs and Transfer Case. Less than $50 if you DIY.
FI decarb service is about $6 for a can of Seafoam.
Air filter is $10 to 15.
Spark plugs are easy $45 if you go all out and get NGK Iriduim.
Jeep KJ just had a bunch of postings on Seafoam, 4WD fluids, and plug changings.

Also get a can of throttle body cleaner clean the TB. I usually do that every 15-20K miles.

I'll be doing the seafoam again soon. Last time I didn't get much smoke.

Pretty much what everyone else said , you can change out the diffs, transfer case and tune it up in less than 2 hours or so. Why pay them that much use the money for mods!

Tom

or just give me what they were going to charge and I will fly out and do it for you! :wink:

Stay away from the steelerships unless it's free warranty repairs or you're rich $$$$$. :lol:

We can walk you though most anything you have a problem with if you're not afraid to get your hands dirty.

I think I will do the trasnfer case and air filter my self. I just want to know excatly what the dealership would do for the fuel Injector deal? Iam going to call them and see. I guess the transmission is not too much money I can pay for that. But if someone out there can change my mind I will do it myself. It cant be that hard.

Find a local shop to do all those things for you. Transmission, 4x4 fluilds all need to be done. The FI cleaner is a joke... at 60K my KJ didn't even smoke so skip that for a good while.

get it done

If you go with an outside Lube place, make sure that they only use ATF+4 and nothing else. A lot of those places will try to rip you off and use some kind of additive. Anything less than the recommended ATF+4 will smoke your transmission.

I gave a call to the dealship to ask them whats all included in this 4x4 services. They said they drain, clean the magnet, and fill both differentials and the same to the transfer case. So now with that info I want to know where is this so called maganent that picks up metal shavings? Is the bolt it self the maganet? Aslo how hard is it to get to the front diff. and transfer case? The injector service is not that big of a deal, I will just run some fuel injector cleaner untill I hit 60k.

Unless you have the Trans flush machine get it done in a shop. I think maybe you could get a fluid transfer pump, drain the transmission through the filler tube. Re-fill it with clean fluid and run if for about 100 miles. Then drop the pan, drain the fluid, and change the filter. This is just a thought I don't know if it's close enough to a flush but it's probably better than a regular tranny drain and refill possibly cheaper too.

The FI service is pretty much running 50/50 gas/seafoam mix through the Injectors using a special machine. Not needed at 24K miles, especially if you use Seafoam through the intake manifold and gas on a regular basis.

front diff and transfer case is basically a drain and fill, they both have drain plugs so pretty simple, rear diff of course you have to take the cover off and clean/reinstall.
