I’ve got an 2012 F150 Ecoboost SuperCrew with a leveling kit and 33” Mickey Thomson’s bought the truck like this from dealership. I’m stumped and annoyed with this noise I’m hearing. When coming to a rolling stop going straight or turning (R) at slow speeds or complete stop I hear what sounds like almost a rubbing/ marbles/ low deep rattle. sound coming from front passenger area. Almost the same sound as those Jeeps made on startups with the muffler shield rattle. Any help or what to look at would be appreciated.

 

CV axles making noise. Is it clicks like marbles?

 

Yup, agree. It is either a blown CV axle or wheel bearing hub. Does this truck have the vacuum hubs? There may be a vacuum line damage causing a leak which is causing the hub to partially engage. I don't know the model years the vacuum hub applies, just throwing that out there as another possible cause to look into.

 

I believe so. It’s kinda like a low tone rattling

 

thanks man I’ll have to look into that.
