Actually, Im afraid I cant diagnose this one. Is the noise in the engine ? I wonder iif its timing chain slap, or a worn piston pin hole. It could also be bearing trouble or detonation, but I think its something else, like a what?? Im clueless,lol.
steering bushings??suspension bushings, t-arm bushings?? does it do it when you turn the wheel or stop??? does it do it over bumps or all the time...I had an odd problem of a strange rattle...in the front end took forever to figure out that there was a dead animal wedged between my wheels and my chassis..it was real nasty
