Ever since I bought this truck, heck I noticed it while test driving it but still bought it. But it has made this loud popping sound. It can happen in succession, or not at all, no rhyme or reason as to when or what causes it. As soon as I got it I replaced the motor mounts, bell housing mounts, rebuilt the transmission, replaced the driveshafts, then later on replaced the front suspension and installed front disc brakes. And replaced the cab mounts and core support mounts. I cannot pinpoint what it is or what is causing it.
The other day I thought GoPro! Looked them up, holy cow they are expensive! But, I checked Ebay, $40 for a refurbished one with a warranty. The seller made it clear they want the buyer to be satisfied, so if anything is wrong with it or goes wrong with it, they will make it right. Cool!
My plan is to strap that sucker to the frame and drive around and hope to see the culprit when it happens. First spot will be behind the rear axle, so if the trailing arms are doing it I'll be able to see it. If not there, then I'll mount it further towards the front each time until I do catch the culprit on film. Right now USPS is showing it hasn't made it into their system. I could have driven down and picked it up quicker than they can deliver it to me...lol... But I wait...
