hey guys i have a vibration/ rattle accelerating slowly through 950 rmp. Its coming from what sounds like the drivers side somewhere infront of the drivers seat... sounds awful. I cant find anything loose under the hood. It only happens at 950 rpm. if i hold it steady at 950 it will continue to do it. Its driving me nuts! figured id post on here to see if anyone has had an issue like this. Probably a long shot but dont wanna take it in just yet. Thanks for reading.

 

Drive shaft maybe.

 

thanks for the reply. Anyway to check that myself? could it have any play in it if i was to yank on it under the truck?

 

Heat shield on the cat?

If it's engine RPM sensitive, I don't see how it could be the driveshaft. It's engine or exhaust related.

 

SIMPLE FIX - Don't accelerate slowly!

 

thanks glc im gonna look into that!

haha unfortunately its not really an option during the morning rush hour! lol

 

Does it sound like an engine noise or just something loose?

 

sounds like something loose. Havent had time to crawl under the truck yet. but will hopefully get on it this weekend

 

check all the nuts/bolts especially on the heat shields tying to the frame/cross member. if you had exhaust work make sure all those are tightened down as well
