Customer Question
2008 Ford F-150 V8...

2008 Ford F-150 V8 5.4L 4x4 Automatic, when starting up hill or engine under load I hear rattling sound like it coming from engine. Also sometimes when starting up a hill its starts bucking motion until I give it more gas!

Mechanic's Assistant: Where exactly do you think the noise is coming from? And how long has this been going on?

I think its coming from engine!

Mechanic's Assistant: Are you fixing your F150 yourself? What have you tried so far?

No I plan on taking to Ford Dealer.

Tim, this noise is not a pinging noise. I have heard pinging noise, this is rattling and when its doing this rattling noise if I left up on the gas it stop. the truck has 106,000 miles on it.
