After such a time trying to reduce the noise level of my 4dr 2000 I havethe weird noise producerscentered in two areas only:
the luggage rack (an annoying come and go noise that made me crazy but happily I found it after trying several possibilities in the doors, seats, rear gate, bumpers, fiber protections, etc),
and a clicking ("light") noise that is related with the rear end of both torsion bars and their linkage (there is a cross member or subframe or wathever the word is where the bars are ending). I know that because even with the force of the hand sometimes you can produce the noise while slightly turning the bars. The sound can be produce when you jump into the truck, engine off, while starting to brake or when accelarating,etc.
Does anyone have the experience with it?, any help not meaning a heavy dismantling of the cross member and bars?.

 

I am guess that if you narrowed it down to the torision bar ends that the bushings have gone bad and need to be replaced. Other than that stuff in the front end that would make noises could be worn shocks, tierod bushings, balljoints, any other front end bushings. My guess is that it is the torsion bar bushings.

 

The clicking is eliminated by turning the adjusting bolt some half a turn to the right. But then it returns. Is something worn there?. The truck is 50,000 miles and chassis is in quite good condition.
