at start up it makes a weird type of noise every time lately. it almost sounds like a radiator fan hittin the shroud, but with the hood open it sounds its comin from near the back of the motor. i have a sound clip, how do u put that in a post?

 

What does it sound like? A thunking, thudding, grinding?...be more descriptive.

 

like a knockin noise, as if a stick or radiator shroud was hiting the radiator fan, lasting a second or 2 starting within a second or 2 after starting the truck.

 

auto or 5 sp tranny?

 

auto, i cant really notice any unusual noise when drivin. and it will do at start up in gear, n, or park if any of that means anything

 

WAG .. maybe starter not releasing fully.

 

I would remove the inspection cover at the trans and look for rust bleed at the flex plate to torque converter studs. If they are loose you will either find metal shavings or rust dust.

 

ok, thanks guys, i didnt have a free chance till today to take a look at the problem. i took the cover off tj and all looked fine, but when i was underneath and someone started it, it was a load noise comin from the starter, hussler, i think i hit the nail on the head, and the starter is only a month or so old. darn remanufactured advance auto parts junk. thanks guys
