Creaking noise when LHF suspension extends
Having trouble searching for people with similar problems, so am unsure if it is a common problem.
While driving offroad I have noticed a creak noise (more of a groan) when the Left Hand Front wheel drops down/uncompresses ie the wheel flexes downwards into a hole. I know it isn't necessarily the suspension making that noise, but that's the timing of it. It doesn't make the noise when the suspension is compressed. The general location of the noise is the LHF wheel. Other side is fine.
Vehicle: '98 2.8 GU
2" lift
How do I go about locating the noise? I've looked underneath for any cracked welds or shiny metal where rubbing could be happening.

Maybe use a 2 poster hoist to slowly lift it while keeping an eye/ear out to try & locate the problem.
You could use a jack under the body but a 2 poster would give you a higher,flatter, more even lift, not to mention a safer one.

I have the same problem but with right rear. Me, not Silver the mighty Mav.
What follows are just suggestions - not had that problem (yet?)
Body mounts ok? Look for spaces between the lowest washer and the mount above it?
Air leak in shock? Creaky poly bush moving in an eye where something is rotating.

Lower spring perch can make a noise.
Metal to metal contact point.
Try a little lube on it, see if it disappears.

THEN IT'S A COMPROMISE

Nice clear photos P4trol.
If there is a gap due to worn body mounts, with the body weight on the chassis, any gap will show up in the area currently obscured by the metal mount - there will be the underside of that mount, the gap, if any, then the rubber, washer and bolt.
The stick looks a likely candidate :-)

Patrol God
You could possibly have a bolt seized in your radius arm bush (the dont know the technical name of object retaining your branch) so when it flexes its rotating the bolt instead of the bush rotating around the bolt.

Yep, you took a good pic of spring perch.
you may not see rubbing as could be hidden by the spring.

If your other stuff didnt fix the problem, ive heard the sway bars/links can make a noise as you describe, especially when one wheel is hanging and the other side is compressed, as this works them pretty hard.

Cheers for all the ideas fellas!
I was unable to replicate the sound using the trolley jack. A short test drive this morning and it didn't make the sound.
