Hi everyone! Recently my 03 TJ (Auto 42rle) has started to shake around 35-40mph, and above. I feel it mainly through the steering wheel and it's only when i'm accelerating, and as soon as i let off the throtte the shaking stops. Does anyone know what this could be? I'm not sure if it's a tire out of balance or something within the driveshaft. Any help is appreciated, thanks!
