Maybe some of you solved the light clicking sound that is hardly to find and is probably related with the rear end of the torsion bars (passenger side I believe). You hear it when the Blazer starts, stops, is bounced side to side (engine off) or even when you go out of it. Is a very clear metallic, not heavy, single sound and it is hard to be repeated in a row.
The mechanic turned a 18 mm nut there and the clicking went for only one day or so.
The other stupid noise I have is something loose at the rear, noticeable in poor pavement. Drivers side rear end, I believed the gas lid, or the jack , the bumper or even the tail lamp, but failed to stop it. Any guess?. Tks.

 

The noise from the front is probably a bad torsion bar bushing , as for the back your going to have to be a little more specific as it could be anything ?

The rear noise resulted in a loose bolt of the plastic part of the bumper. There are 5 and 3 screws. The plastic piece hit the steel bumper under special road vibrations.
The clicking noise is in good health, despite I greased all around. Still is heard at the torsion sub frame. Is not permanent but if you rock the car one or two clickings may be obtained, but not always.
