Discovered some driveline whine in my 1992 Daytona IROC R/T after a spirited weekend of driving at the track with tons of 30+ PSI pulls. Any time I put the car under load I can hear the whining. The volume increases as the speed increases. The car has a built 523 with an OBX. I welded the bearing race to the shaft as recommended by Jackson. Im not sure whats going on here. I took a video the other night and I hope that will help diagnose, any help is appreciated. Thanks in advance.
