I've been trying to locate a thumping noise from the passenger side floor for a long time. It only happens over small bumps. The front upper limit bump stop is touching, but I haven't cranked on the torsion bars, just a slight adjustment on the drivers side to correct ride height before I did an alignment. It does have KYB's all around, all bushings, body mounts, etc. checked. One of these days I'll shave the upper limit bump stops a bit to see if that's what it is. It's going to be a PITA to get them out.
