2003

My 90 degree air locker hose fitting on the front differential is loose and leaking. What is the best way to replace the fitting with a new one? It seems like it is a press fit into the housing but what does the barb fit into inside the housing? Can the fitting be pulled/pried out and a new...

I haven’t quite started my build yet but I figure now is as good as time as any to start the thread. I have a 2003 TJ Sport in Solar Yellow as I briefly mentioned in my new members page. About the Jeep as it sits: Nicknamed - Wolverine 2003 TJ Sport - Solar Yellow Factory Rear Dana 44 3.73...

Greetings, I have a 2003 TJ 4.0 5-speed manual. My coolant looks murky and the hoses could use replacing. I want to upgrade to a better aluminum radiator since I have to go through all the effort anyway. Looking for some options that people have had success with. I have looked on a couple...

Hey all. I’m brand new to the Wrangler community and just got my hands on a 2003 TJ with the 2.4L I4. Well taken care of and has just over 60,000 miles on it. It’s an auto, bone stock. I originally had the intent of doing a 4 inch lift, 33s, doing the SYE and driveshaft, adjustable track...

Purchased a 2001 4.0L 6-cylinder TJ a few months ago. Only had 140,000 and the body looked good. The frame looked good to but as it was getting lifted at a shop for a new clutch to be installed, the mechanic said the frame cracked and has a ton of rust underneath there. I live in North East...

I plan on swapping the 4.0 in my current 03 Wrangler for a 2006 4.0 and was wondering what to expect. Mainly, I've heard that the ECUs are not compatible. Some sites have said I'll need a full drivetrain swap, others have said a custom TCU. Hoping to get a definitive answer here. Thanks!

Alright so i have a 2003 tj with a 4.0 and 5 speed manual. Today i went to start up and nothing. Starter tested. Ignition switch replaced. But if i roll start it on a hill it kicks right up. And runs fine. While running it has a kinda of lick or knock sound from the transmission when the clutch...

Hey, Wrangler TJ Forum! I'm new to the site and wanted to see what y'all thought about my 2003 Wrangler. I just got it and wanted some feedback or advice on maintenance, upgrades, or just things that I should try. It's my first Jeep so I'm beyond excited about it and how it drives. Just take a...

Hey Guys, I bought a 2003 Jeep TJ recently with 90k miles and it has a noise coming from the Transmission/Transfercase area and I am trying to figure out what is causing it. It is a knocking/ticking noise that increases as I accelerate and doesn't happen when I rev the engine in neutral. Its...

So I met a local guy who has a set of 4 black 2016 JK Rubicon wheels with about 50% tread left on the tires. He is having trouble selling them as he doesn't have a 5th and he has offered them to me for $300. I know I would need about $200 in adapters to make them fit my 2003 TJ. But as I have...

Hey Guys, So I just bought my first TJ today at Auction and have now come to the realization that the 4wd doesnt work. When I put it into 4WD High, the lever sounds like it is engaging but after I do that I am unable to shift into first gear or any other gear(5speed). It feels like the...

Hi all, this is my first time posting and I'd appreciate any and all advice! I am a college student and I am looking at getting a TJ as a DD first and for off-roading second. I have done a lot of research on both but I'm still stuck on deciding. From what I learned so far is that it is better...
