    Rear axle gearing question

    I'll bet the gears have already been changed because if it has 3.21's and 35" tires you would know it still had those gears. My Jeep had 35's on it and 3.21 gears and a manual trans and I couldn't use 6th gear unless I was doing about 60 mph. If you have a auto trans you'd really be having...

    Thanks for the update. Sometimes you just need to pat them on the back for a burp to come out.

    2015 JKU Overheating With No Heat

    Did you have your heater set to heat when you did the burp? Heater core shouldn't have anything to do with the T-Stat.

    2015 JKU Overheating With No Heat

    You need to raise the front of the Jeep up about 6-8", radiator cap off, engine idling, add coolant as it starts dropping.

    My 08 when I bought it had 35's with 3.21 gears, still has the 3.21's just stock tires now.

    Let's play guess the gear ratio

    That's what they should be for 35's, maybe even 4.56.

    Low temps and boiling sounds from 3.8

    Have you tried changing the water temps sensor that the ECM reads, i'm thinking someone else did that and fixed there issue.

    Low temps and boiling sounds from 3.8

    The sensors only read the temps don't have anything to do with controlling the temps, the T-Stat controls the temps along with the cooling fan.

    Low temps and boiling sounds from 3.8

    If you had the coolant drained out you'll need to burp the cooling system, remove the cap raise the front up about 6" and start the Jeep. Then as the coolant lowers add some more to it.

    Anyone know what this noise might be?

    I can't tell anything from the video but my guess would be a U joint/joints. Does it make a clunking noise when shifting from forward to reverse?

    Anderson Cable Connector Ratings

    I bought this for the front of my truck since it would catch the most crap, it had to ship from I think Australia so order it before you need it. https://www.amazon.com/dp/B09KCGKLPM?tag=jkforum-20
