    What did you do to your jeep today?

    Your KJ is still in very good condition! Wonder what OBD2 codes are pending? What muffler are you installing?

    Really bad sound, is it the transmission?

    My goodness that is quite the noises present there :eek: Time to drop the transmission pan & inspect filter, see if there is any particulate matter in pan. Use ATF+4 fluid. May consider a trans shop that can read any pending or stored codes as well. Best of luck.

    Airbag light

    Welcome to the forums. You will need a high end shop scanner. Find a shop with a Snap On Modis Ultra. Have them search for any pending or stored codes, also while driving. Record and note any applicable codes.

    Codigos p0430 y p0420

    Any Member have a list of KK trouble codes? My thought is that possibly the fuel trims. Use only NTK brand oxygen sensors. Which brand of catalytic converter did you install?

    Bad muffler creating vibrations/pulsing?

    HJ- I'd also consider new KJ copper core spark plugs, NGK ZFR6F-11G if they have not been replaced in a while (35k Miles) Here is the top rad hose part number for you as well. Hopefully still available I hope !! Luckily I replaced my upper rad hose before it spewed everywhere. ;) Only use Mopar...

    Dyno Test

    How much $ does a Dyno test cost? Generally only large horsepower engines are Dyno tested & tuned. I did find this thread KJ thread though. https://www.jeepkj.com/threads/kj-dyno-tuning.63078/

    Power Steering Fluid

    Are you having to replace the whole rack & pinion, pump, return pressure lines etc? Probably ATF+4 would be the best option. After 2003 ATF+4 was used in the KJ's as the standard.

    Front impact sensor

    What scanner are you using? 2002 is a very early model. What OBD2 codes are you getting? The dealer may still have a "star scan" scanner kicking around. Other than the star scan, the next Best scanner to use is a Snap On Modis Ultra.

    Thermostat housing leak suggestions on new thermostat, or temp rating

    Drain & Inspect housing first. Probably best to replace the lower rad hose & use the correct Mopar thermostat, which has the built in gasket.

    Speedometer Not Working

    The 2 wires should then be fully inspected. Keep in mind wires are in between the split loom tubing. Are there any OBD2 codes present?

    Speedometer Not Working

    Just above the rear differential, is where the speed sensor is located. The sensor may need replacement. It has a 2 wire connection, with wire loom tubing. A known issue and inspection for chaffed wiring may be present as well.
