With wimpy road tires on now, I can tell my 93, with 350,000 miles, has developed some rattles and squeaks. Tightening door and hatch bolts, and lubricating areas solved most issues, but I think my inside rear plastic panels are causing most of the remaining interior noises. Are those panels a common source of noise? Is there a good way of determining if they are causing the noises? My hearing is sufficiently bad that I can't isolate the source, but passengers have suggested the panels. If it is the panels, how difficult is it to re-secure them? Any other likely culprits? Thanks.
