I have a 2003 Chevy 4×4 . When I pull out and take off first gear makes a weird grinding thumping kind of at low Rpms . I'm thinking down the line of a cracked flywheel . I parked it immediately .
My 2003 Sierra started making a wired grinding and thumping sound that
thumps faster as I spped up . I shut my truck off as soon as it started . I'm
thinking It might be a cracked flywheel I can't be sure . Has anyone had this
problem and could possibly have a Sierra 4×4 that's had this happen and
