I currently have a 2017 Jeep Wrangler with a 2.5” lift and 35” tires. Scratching/Grinding sound whenever I start the jeep cold then begin driving. The noise sounds like it is near my front drivers side tire and it sounds like tranny scratching sound or a vibration sound. I have tried revving the engine in neutral and nothing happens. The noise is loud and goes away after I drive down the block and turn a couple corners maybe after it warms up a bit. Its driving me crazy. anybody encountered this before?

 

Not a chirping sound? Does the pitch change with rpm? If so, could be a belt or a bearing in a pump or idler pulley.

 

Not really chirping more like grinding or scratching. Might change pitch a little if I slow down but definitly if i nail it after startup it will be loud. Def doesnt do it anymore after driving for a bit. Im just worried its somethin serious
