Front end noise diagnosis Toyota hiace supercustom 2wd automatic 1994

Whirring noise in the front (unchanged if in neutral) have replaced wheel bearing and upper ball joint Hiace supercustom 1994 2wd automatic

It’s a whirring wom wom noise above 30km, disappears at 60km in the front LH. Is unaffected by turning corners, unaffected by shifting in to neutral. It’s not too loud, but I can hear it over the stereo. It’s a whirring humming, not a squealing or grinding, it changes a bit in pitch and speed but not too much. Had several people listen to different areas of the van who all think it’s coming from LH front. I was hoping it was wheel bearing/upper ball joint, the rubber gasket of the joint had torn and it had a lot of play, bearing had a bit of play, but I replaced both and the noise continues. I also got four new tires, so ruled out tire cupping. What else can I check in that area? Is there another bearing (I’m a very diy mechanic) Is it possible the noise is carrying from the RH? Is it possible it’s a drive velocity joint? Would that still whirr at the same pitch when it’s flicked into neutral ? Thanks for reading and much appreciation of any answers.
