    Trying to learn more about what is needed and recommended for an upcoming gear swap in my 2017 JKU. I will be upgrading from the factory 3.21 gears to 4.11's. The Jeep will have approx. 50K miles on it once the gear swap is performed. In reading previous threads the Eaton Truetrac has been...

    I recently got 35s on my 2012 JKU sport. It’s got the 3.21 gears and honestly it handles it way better then would have guessed but I can definitely fell the power difference and see the gas mileage difference. I’m going on vacation in August and will be traveling a good distance with a lot of...

    Hi first time jeep owner here, also my first car in general. I was going 50 on a long road and I heard my engine revving. I looked down at my odometer and it read D1, which I’m guessing was some gear change? I don’t know, I’m sure I changed it on accident when I put it in drive but it’s never...

    Hi, I heard that 2022 wrangler is open for ordering and they are offering 4:88 gear ratio for the cost of $850(aprox) and this is for 2door manual. Also there is a price increase of $700. I already have an order in place for 2021, but I get an option to change it. so is worth it? How does 4:88...

    I had a 5.38 Revolution gear and pinion put in, about 3 years ago (so it's outside of the warranty!). After some grinding noise that went along with the rotation of the wheels, I popped the rear diff cover to find a lot of metal in there. I put the cover back on, took it to a different shop than...

    Hi there! This is my first post in the forum and I am desperate for some help! I know there is someone out there with the right information :) I have recently bought a 2003 Jeep Tj. It grinds when going into 5th and 6th gear, when it actually shifts into the gear it will slip out into neutral...

    I'm thinking about changing the differential gears from 3.73 to 4.10. I have a 2016 JKUR w/ 2.5" ARB lift and 35s with the automatic. Anybody know of any issues with the change?

    I have a 2012 JK, 132,000 with the 6 speed manual. It the last couple of weeks it has developed a roar in the transmission in 4th and 6th gear. The roar goes away when there isn't a load on it like if I clutch it or just let off the gas and coast. Attaching a YouTube link. It doesn't sound too...

    We go through this stuff at our rides and camps, thought I'd make a little video sharing some of the stuff we have in our rigs. Want to aid new trail users to some of the basic stuff a lot of us carry. http://www.youtube.com/watch?v=jCf4lBQBY5Y&t

    I'm looking to regear my 2017 JKU from a 3.21 to a 3.73 strictly for towing purposes. I don't currently plan to but larger tires on but if I do in the future, I wouldn't go higher than 33's. I am moving to Alaska and will be towing a 5 x 8 cargo trailer with me. The trailer itself weighs 1,000...
  13. TJ Technical Discussion
    Hello, I've researched thoroughly and haven't found any threads describing the exact issue I have so I'm creating a new one. I have a manual (NV3550) 2003 Wrangler. Often, when I am stopped with the engine running it will be hard, almost impossible to put the Jeep into first. On the second or...

    Hello All, Just bought Sahara Unlimited 2015 (Stock), during my test drive in the sand I noticed that the performance of the car in sand on 4Hi gear was really low. RPM was stuck below 2000 rpm even on full throttle! I shifted the gear to 4Lo the performance was amazing! I was checking with...

    Hello everyone - I bought my 2017 JKU in June 2017. All seems fine except within a few days of driving it, I noticed this faint grind noise that happens from second gear through fourth gear of my 6-speed manual transmission. The gears are engaged. The car runs. It's just, that sound is...

    Hi Guys, 1st post here. Need some advice on changing diff ratios. I have bought a 'new to me' 98 TJ with 34" Tyres. Looks great, drives like stink. Have it 2 months and havent used 5th gear yet. Anyhow I have decided to correct the ratios to 4.56. Parts are in short supply here in Ireland...

    Hi guys, let me begin by saying that I know there might be a thread about this before but I can find it. So I have a '09 auto 2 door JK X. I have put 35s, front and rear steel bumpers, led bars, suspension and still run the OEM gears which sucks. I bought the Superchips FlashPaq to shift the...
