DRIVETRAIN CRACKING??

[Black Stang 97]

Everytime I take off and when I gas it on gears 1 thru 3, my car makes like cracking/popping noise either on the motor or the tranny, I thought it was the driveshaft U-Joints but I changed em and it still does it, I cant figure out what it is anyone have an idea what it could be?? I read on a magazine that the timing belt starts cracking after its old, is it true??

If it sounds like a clunk, its probably the infamous mustang driveline slack. Mine did that when it was stock, and it still does.

WELL LIKE IT SOUNDS LIKE WHEN THE U-JOINTS ARE GONE, IT LIKE CRACKS, SOMETIMES MORE THEN OTHER, IT MOSTLY DOES IT WHEN I TAKE OFF IN 1ST GEAR....

thats normal for a stang. also, next time you do your spark plugs, ditch the Bosch 4's they are crap.

is it normal?? before it didnt do it, and now that I kinda been racing it, it started doing it. you think it can be the tranny oil?

Same problem here. I've narrowed it down to play in the d/s. It's common annoying but common.

well, when was the last time you changed the trans fluid? it really should be changed out every 30k miles at least.
