I recently grabbed an 88 k1500 silverado $500 project. This guys wife drove it across a parking lot and slammed it into a Dumpster (on purpose), cuz he was talking with some Hotty's at a Wedding Reception, she must be the jealous type. Anyway it crunched the front end in a little. I replaced inner/fenders and radiator bracket, hood , grill blah, blah blah. oh yeah, hit hard enough i had to straighten the rightside frame out back about 1 foot. All square now though.
It has the 5.7 and the 700 4spd automatic with +- 120Kmiles on it. Runs and drives good. Just started after driving on highway for 20 -
40 miles a knocking sound starts up only when in park or neutral. If i pull her into reverse or a foward gear the sound goes away. Pretty substancial knock too, I thought maybe a rod at first but since it subsides when in gear I was thinking Flywheel Bolt? I came off the highway pulled up to my buddies house, put it in park at idle speed and all you can hear is , sha-bam sha-bam., sha-bam. Pull it back in drive and nice and quiet.Anyone seen or heard this b4?
