Default 4.2 rattle?

noticed that my truck will rattle intermittently when im in park, and especially when
i put it in reverse but only at very low rpm. today I replaced all the pulleys thinking they might be the cause, but still experiencing the rattle. any input on what could be making the noise would be appreciated.
my truck is an 07 4.2 automatic
