Can't track down the *ping* noise. Feedback please!! So I keep getting a ping noise coming from the trans/drive shaft area with a change in load(accel and decel).
Things I have replaced:
Trans Mount(poly)
Torque arm mount(poly)
Transmission(from 4l60e to T56)
Read end(from LT1 to LS1)
Drive shaft u joints(spicer)
Also had the shaft checked for balance.
Now, the car is lowered and has LCA relocation brackets(lowest setting). Upon harder acceleration I can feel a strange vibration.. but it is fine under normal load. My Y-pipe is clear of the frame so I know it's not that. Is it possible the drive shaft yoke is bad somehow? I have a small leak coming from my pinion seal with both auto and manual transmissions. Previous owner of the T56 claims it never leaked a drop and I believe him. I would really just like to stop replacing parts and learn from someone else who solved this same problem. Any feedback what so ever is greatly appreciated. Thank you!!

have you lifted your car and checked for fresh marks? thats what i would do. put her up on a lift, and that would be the best that i could do. as for the vibration it sounds to me like maybe an off balanced torque converter tho i dont know how that could have possibly happened. the yoke should be just fine i havent seen too many chevy's where the yoke wasnt able to fit into another chevy tranny. and when i say i havent seen to many i mean i have never see that problem.. one last thing i can offer is that it could be the angle of your drive shaft. I hope this helps you at all. and i thought even if i am wrong.. at least i put something up here to help you out.
