Clank noise, Torsion bars at Rear

[Big T]

On the ‘94 I get a momentary clank or ping noise when first backing up. Had my son observe while backing up and stopping and he said it was coming from the rear of the torsion bars where they insert into the crossmember. This also happens when going over speed bumps. Any ideas what is going on? Most recent suspension work I replaced the stamped steel LCAs with forged LCAs.

are there any bushing in the ends of the torsion bars like on the older trucks?

No they were rusted in and impossible to get out.

Wondering if I should harvest a non-rusted set from a CA Truck.

If the torsion bars are moving enough to make noise you should be able to get them out. Unless maybe it's the keys
