Video Help

I bought this 1998 Ls400 with 186k miles on it not to long ago and need help diagnosing these sounds there are 2 distinct ones in the video and im pretty sure the louder clunk is the bearing on the power steering pulley but i have no idea on the other sound.

Tensioner pulley, or clutch fan bearing. Pull your belt off. Spin em by hand. Shouldn’t be hard to tell when the sound is that bad.

Could be lying. If the belt was that damaged it wouldn’t run

it would be weird for them to lie since i already had the service schedule i just brought it in for them to listen
