i have a 2020 chev silverado 2500 hd with the 6.6 gas and 6 speed transmission, im getting a growling noise coming from which seems to be from the front during acceleration and if i take foot off accelerator the noise quits , does any one have any suggestions on what this could be . i took front drive shaft off and noise was still there , i had replaced rear u joints also .
