Hey guys, I traded my 12 R/T Classic 6-speed for a 16 SRT 6-speed. Now, when I drive my SRT and step on the gas, even just driving normally, I get a whirring sound from the rear end. My R/T with stp did not do this. Honestly, the SRT sounds a lot like the Dana 60 with 4.10s in my 69 Charger. Is this normal for the SRTs?
