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.
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.
Water leaks are no fun.
My KJ windshield was leaking on passenger side & failed the water test. Glass shop successfully removed glass & re sealed it & it still leaked.:eek:
Then I ran a fine bead of clear GE silicone along the top edges & it stopped.
Remove /pry up wipers to access the plastic...
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?
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...
Moved this to the CRD diesel Section.
There are crd diagrams & parts listings etc to be found in link below, hope this helps.

How much $ does a Dyno test cost? Generally only large horsepower engines are Dyno tested & tuned.
I did find this thread KJ thread though.

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.
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.
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.
Mine has a black protective screw on plastic cap on passenger side of fuel rail, used a flashlight to better see inside.
I wonder if you tried screwing in a fuel pressure tester may help seal it again?
Take the fuel pressure readings while there. Not running for 10 minutes, Vehicle running etc...
