TING noise going from park and drive ?

[blazer2007]

80 1/2 ton 2 wheel dr. 350/350 stock but mostly all new in the last 4 years. Tranny is the lock up type,is static lowered,flip kit and a cut coil. I do have a bad drum brake that is scarred and is need of a new one but the sound seems to come from the front. Checked u joints which are fairly new,front one has a tiny bit of play.It,s random ting when going from park to reverse or drive,not all the time but more times than not,it,s not a clunk just a ting. I did a quick check but don,t have a day off until Wed. so was looking for other places to look. Doesn,t do it when driving and shifting. Thanks as usual. I,m sure I missed some useful info.
