I have same issue with my 2018 trd off road4x4

I also hear a sound on the front end passenger side of my truck when i go over small bumps on road that have been repaved or through rail road tracks. Only at 15mph or slower. I noticed it a week after i bought my truck. Took it also to dealer and the mechanic said that's the way these trucks are, i said, i don't think so.something has to give i more less have an idea what it might be. I saw a clip loose on passenger and driver s side wheel wale. And its that one only one clip which has it on the same spot on the passangers and drivers side. But it seems as is a strut is loose or something in engine bay that holds the intake
