From day one, the one thing that I've never been able to resolve...and Isuzu has always refused to try to fix...is a rattling/squeaking noise coming from the rear somewhere. Sounds like it's coming from the passenger side rear quarter panel. Maybe the rear door latch? But it's hard to discover that when I'm the one always driving and having people crawl around the back on a semi bumpy road opening up the panels and spare tire cover. It's been 13 years and it hasn't really gotten that much worse over the years...but it's definitely still noticable. I put in a nice sound system about 7 years ago so usually that covers the sound, but recently, i just wanted some peace and quiet...no radio...just me, my VX and the rattle/squeak from days of old. Any ideas?
