2002 JGC limited supention needs

Ok I have a 2002 JGC limited with a 4.7 with the N in the VIN.i have a few questions on supention. First it bottoms extremely easy so I assume I need front shocks. I just replaced rotors calipers and brakes. But have a few more issues. The jeep like to wonder a bit over lane I am driving (no death wobble the I know). I will attach 2 short videos first is one of the joints I know that the tie rods ends are bad but what else. The track bar seems to move around the bolt but the bolt is solid. The second video is more troubling... in reverse if I touch the brakes while I am back up touch the brakes, when I release the brakes there is a clunk. So I filmed it and the whole axle rotates a little up in the dictation of th braking. When brake is release so is the tension

Looks like more than few things are past their useful lifetime. How many miles?

Your axle will rotate a some under acceleration and braking but that's a little more than I would consider "normal" Your control arm bushing are probably shot and that is what's allowing the "rotation".

Wandering, I would get the TREs done and see if that tightens it up. If not your steering box could be failing.

Failing shocks will also compound a lot of other issues.

Have you checked your ball joints and wheel hubs?

I agree I most likely need to replace many parts ! as I have been restoring this for a while. miles are in KM but after using a converter said 169,000. I know both sides has at lest 1 TRE bad, so I will replace them all both inner and outer. Not suer how to test the control arms or sway. the hubs seemed ok and using a pry bar I think the balls are ok. i saw some movement in the track bar (first video) and as to the axle rotation I am very concerned. That is why I am trying to know what is bad how to know where to start what is the worse

Control arms you can grab them and see how much movement they have. They should be fairly tight but if they are sloppy time to replace. Sway bar link is a visual inspection and at the mileage probably need to be replaced. Same with the sway bar bushing.

watching the second clip the bottom arm joints look ok, the upper arm looks and sounds like there's nothing left of the rubber bushing!
this would go a long way to explaining the handling you described, as the axles caster angle is constantly changing as it rotates back and forth.
I would just get everything for the front TRE's, track bar(Panhard rod) bushings, all 4 control arms with pre installed bushings plus the 2 bushings for the axle.
that much movement puts a lot of stress into the bolts holes and will oval them out very soon.

Agree with the other guys. Replace all CAs and bushings, TREs, sway bar bushings, end links, track bar. Everything with a bit of rubber in it. While you are in there, spring isolators and bump stops would be a good idea. Same goes for the rear. The rear upper CA will cause wandering when the bushings go. Rear lower CAs will cause throttle steer. In your case, front end is clearly priority.

I completely agree I need the front end done first. And looks like almost everything has to be done upfront. Now the real hard question I k ow I can only afford to do some on each paycheck, so what order should I replace all of it in? I was thinking of starting with all TRE's and shocks. Then track bar and sway and control last ? ... if I am wrong let me know

the first thing to replace is the top control arms before it damages either the frame brackets or the axle, as they are completely trashed.

Yup, front upper CAs first. They are also the hardest because the axle side bushings are pressed into the axle, not the control arms.
