kruuuugg sound when backing

[artpogi]

Lately, I've been hearing this kruugggg noise/sound kapag umaatras ako, whether in straight line or with the wheels turned, the sound comes from the right front side. The sound only comes out kapag umaatras lang ako. Kung minsan naman wala

Yung pang-ilalim ko (tierods, ends, ball joints and bushings) are less than a year old, my front shocks are 4 years old na pero wala pang tagas.

Going forward, I don't hear the click, click or tok, tok sound kapag lumiliko ako, which I believe is attributed to CV joints.

Can the kruugg noise also be a CV joint problem?

thanks

update .....

I was in our empty office parking lot just a while ago and I did the following:

move forward full circle with wheels fully turned to the right - no kruuug sound
move forward full circle with wheels fully turned to the left - no kruug sound
move reverse full circle with wheels fully turned to the right - no kruug sound
move reverse full circle with wheels fully turned to the left - no kruug sound
move reverse in straight line with wheels straight - kruuug sound came out

hmmm.... so is it safe to rule out the CV Joint's?

any suggestions?
