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.

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.
