So after replacing the carrier bearing, getting 3 new u-joints and balancing the driveshaft my noise is still present. Still only when under load going uphill about 40mph. almost like a grinding noise but not as harsh. more like rattling. Still pulls fine and has good power, shifts fine but the noise is there. Is there any bearing or anything in the motor or transmission that could cause the noise without effecting performance? At least for now. Im still leaning towards powertrain just because its only when moving and under load but not sure. any help would be greatly appreciated! U-Joint slop - YouTube
thats a vid of the me moving the front driveshaft back and forth. Is that enough to make a noise when driving? or is that normal?
