A creaking/popping noise is heard from the front end of the SC400 while braking at slow speeds. Ex: after shifting from forward to reverse and vice versa while pulling in or out of parking spots. Slightly more than light braking while approaching a stop sign.
Attempted repairs: New lower control arms incl. lower ball joints
New upper control arms incl. upper ball joints
New sway bar end links
New sway bar bushings
New steering rack bushings
New Shocks and springs
Nothing worked!!! or worse
Retorque the (4)17mm nuts which hold the aluminum crossmember(cradle) onto the unibody chassis.The 4 17mm nuts should be torqued down to 94ft/lbs.
Another to check while you're under there are the (6) 19mm bolts which hold the steel crossmember located rearward of the aluminum crossmember. The 6 19mm bolts should be torqued to 148ft/lbs.
A 17mm deep socket/19mm socket, 6" extension, and a long handled ratchet will do the job just fine.

Hoping for the best on this. I also have replaced LCA's and went to a supra/bilstein coil. Still have a little clunk from the front right. Same parameters as you describe as well. Thanks. I'll tighten them this weekend and reports back.
