Pop after warm start up

[fifty]

Hey all. first off, tried a search and didn't find anything...
Second...the truck... 52,000 mile 2002 F-350 CC DRW, AIS and MBRP only.
Third...the issue:

When the truck is already warm. So lets say I drive for a bit, stop at the store for about 10 minutes, hop back in, fire her up, 10 seconds later there is what sounds like a deep "pop" coming from the passanger side of the engine compartment. Almost at foot level of the cab. And only one.

I have only had the truck about 2 months, and its a regular occurence. No check engine lights.

I have no idea what it is...you?

Is your foot on the brake pedal when it happens? My abs module on both of my trucks will do that when it runs its self test. Its usually when im pressing the brake though, like if I start the truck and take off before it has a chance to run the test. Basically the abs self test becomes loud if theres brake pressure being applied.

Try pulling the big abs maxifuse, and if the noise goes away then put the fuse back in and dont worry about it.

No, my foot is not on the brake when it happens...Odd thing though today. It did it when I got off work today. Truck had been sitting for 10 hours. And it was 55 degrees out. So I guess its doing it cold too...

Hmmm. I am going to have to watch for that

Mine makes a sound similar to what you are describing.I am leaning towards the caliper sticking on mine.

I am fairly certain its not the caliper sticking. It happens with my foot no where near the brake pedal as well as with my foot on the brake pedal.

I would be happy if it were just a sticky caliper...lube it and problem goes away...

Might try having someone take a ride with you and see if they can help you narrow down the area its coming from.
