    What would be the best gear ratio for a daily driver?

    At 130k miles, our 2003 TJ (Oreo) is due for some differential work. I’m a novice on gear ratios - hoping for some good recommendation - Oreo has the 4.0l I6, 42RLE tranny, lockup torque converter LSD differential, running stock wheels and tires (P225/75R15’s @ 28.3” diameter). Stock gearing...

    Texas Metra center bezel for -03-06 double din upgrade

    Used but in ”like new” shape (except where I had to slightly shave the rectangle that the radio fit thru). I just removed from my ‘03 after running a 2 din radio for about 2 years (I reinstalled the old round corner bezel along with a new PSD50WRJL). Pictured is all I have for the bezel. No...

    Time for another fuel pump again?

    ‘03 L6 with 127k miles. Replaced fuel pump September 2019 with a Delphi FG1221. Fuel pump comes with new bottom mounted filter. Lifetime warranted fuel pump when installed with new filter (hmm, above?). This week, Jeep getting harder and harder to start, acting very much like it did when I...

    Temperature gauge soars but engine not hot

    OK guys - I got a weird one for you! ’03 TJ 4.0l. 122k miles. Some PO along the way installed aftermarket radiator. When I bought it, CEL bulb was not there. Deal I made with Seller is that it would pass emissions - and he said it would once the readiness codes set - just drive it around and...

    Surprise! P01281 code

    Uh-oh, a new issue just tonight - Today I drove about 150 miles to sell an old soft top and buy a couple of axles. Got home about 1:00. No issues with the Jeep when I killed the engine. 5:00, crank up to head to Town Council meeting, 15-20 minute run time. Kill engine, no codes. Get out of...

    WTB: Dana 35 with ABS axles (left and right needed)

    I’m updating a 1997 Dana 35 axle to allow for ABS. Already found a set of backplates, I just need the axles with tone rings. Located in North Central Texas and wouldn’t mind driving a reasonable distance to pick up. Or, I hear Fastenal ships store to store for a reasonable price (Blue Line) but...

    A word about jounce bumpers (or those rubber things hanging from a metal cup inside the top of the coil spring)

    When we bought Oreo a couple of years ago, when I was replacing the shocks I noticed a yellow colored hard rubber something that were all knurled and cracked stuck up inside the top of all 4 coil springs. After researching the Jeep parts book, I found that these rubber thingies were known as...

    Dana 35 from 1997 going into a 2003—brake upgrade to include ABS—disc or drum?

    Hope someone has some ideas - Bought a 1997 Dana 35 rear end differential from a guy the other day with what I thought was the proper info that all ‘97 - ‘06 Dana 35 rear differentials were ABS capable, to replace the whiner in my ‘03 - which meant to me that if the sensors and tone ring on the axle...

    FYI - ‘03 TJ Jounce plug/bumper replacement

    Just thought I’d post my experience in renewing my jounce plug/bumper/stops on my ‘03 TJ Sport - The old jounce had pretty much rotted away, leaving chunks of rubber up inside of the holding cups. The cups are at the top and inside of the coil spring at all four corners. 1. Use a bottle Jack...

    Looking for ideas on restoring Ravine wheels

    As the title Ravine wheels on my 2003 are in pretty bad shape, have been since I bought the Jeep. The issue isn’t so much the road rash as it is the peeling paint. Just looking for ideas/suggestions on how to proceed to clean them up and what to repaint with. From the few threads I’ve come...

    Catalytic converter scrap dealers

    Earlier today (or was it yesterday) I posted a question about replacing the complete exhaust system, including the cats, in my ‘03 Wrangler. i Know there is value in the old cats due to the rare metals used in them - so my question is, anyone whose replaced their cats found a good “buyer” or...

    Questions about renewing complete exhaust system on 2003 TJ

    As noted in the title, I think my cats have reached EOL. I think this Jeep lived most of its life in Oklahoma, the chassis was/is pretty clean with little or no rust when we bought it 2 years ago with 103k miles. No CEL’s being thrown, no odd sounds coming from the exhaust system. But it seems...

    Texas Assorted TJ parts

    Help with whine from rear end

    OK - got another long winded question - My '03 TJ with automatic and Dana 35/3.73 rear axle whines. PO or O's didn't take care of her - when I got her the lube was chocolate milk. So - what to do, what to do. I'm not a rock climber so plan to stay with 3.73. 155k miles. I'm not into rebuilding...

    '03 Wrangler Sport / 42RLE / P0700 / won't downshift

    Hey all - Like the subject line says, 2003 TJ Wrangler Sport, L6, ~115K miles. We've had it going on 2 years. Tranny has always seemed buggy, but today it threw a P0700 as we were getting on the highway in Santa Fe (we're traveling right now and won't be home until tomorrow). I could tell it...

    Alignment

    I recently had my '03 TJ 4 wheel aligned after an incident a few weeks ago in the mountains of Utah (a car broke loose going around the curve at Boulder Summit - he was going southbound, we were going northbound. His tail end came swinging around and I was able to maneuver such that his rear...

    2003 Jeep Wrangler Sport - No Rear Locker Relay

    My '03 Sport has not had the Rear Locker Relay installed in the under-hood fuse panel since I bought the Jeep a year ago. Does it matter? Jeep drives OK with no issues, and I don't plan to go rock crawling with it - but I'm anal and like to have things as OEM as possible (who knows, whatever it...

    Anyone replaced a tinted windshield lately?

    Well, after doing something stupid while attempting to use the Rain-X kit to repair a ding in my windshield, I now need a new one. Anyone done this lately, and if so, cost? Mine is tinted as opposed to clear glass - tinted is needed here in Texas (and I don't mean after-market tint!). Been...

    2003 Wrangler cruise control install

    My '03 doesn't have Cruise Control so I started researching how to get it. I found a post from earlier this year where someone was wanting to do his '04 ( https://wranglertjforum.com/threads/2004-jeep-wrangler-sport-aftermarket-cruise-control.19096/#post-348640 ), but thought I would update for...

    Using the OEM Tire Jack

    I've got an '03 with the OEM jack. Now before some go off the handle and tell me to get rid of it and buy a hydraulic bottle jack from WallyWorld, Harbor, or Northern - hydraulic bottle jacks have 3 issues that the OEM bottle jacks don't have - 1) You don't have to crawl under the Jeep to...
