Scott.T Posted July 24, 2012 Share Posted July 24, 2012 Every once in a while when I take off from a stop the truck will make a grinding sound that will last for 1-2 seconds. During this period of grinding it seems to cut accessory power, the radio turns off but the truck stay running. It really only does it in first gear, sometimes 2nd if I do a rolling stop and take off in second. It seems to only do it when the rpm's are low on take off. Has anyone experienced this before or have any ideas? Thanks Link to comment Share on other sites More sharing options...
nunya Posted July 24, 2012 Share Posted July 24, 2012 Alty trying to lock up at low rpm? pop the belt off and spin it by hand listening and feeling for grinding in the bearings Link to comment Share on other sites More sharing options...
nismothunder Posted July 24, 2012 Share Posted July 24, 2012 Alty trying to lock up at low rpm? pop the belt off and spin it by hand listening and feeling for grinding in the bearings Cable coming loose? Even if the alty locked up it should still run off the battory with out interupting the radio. It could be that the 2 things arent related but happen at the same time.

Slartibartfast Posted July 24, 2012 Share Posted July 24, 2012 Maybe a motor mount is bad and it's stressing a wiring harness somewhere? Link to comment Share on other sites More sharing options...
Tungsten Posted July 25, 2012 Share Posted July 25, 2012 The alternator could be on its way out and the battery is not charging properly. Link to comment Share on other sites More sharing options...
