When I back-up my super A the left side drive seems to have a bearing popping. In forward there is no noise.
I jacked up the left side and there is no loose movement in any of the drive, all the shafts seem tight. You can spin the left tire in either direction and there is no bearing noise and rotation of the tire is smooth. I took off the transmission top plate and transmission looks good all bearings are tight.
Any ideas on the bearing popping in reverse on the left hand side?
Thanks for your help.

Check the bolts that hold the rim to the wheel center. That is generally the source of this type of noise. They may seem tight, but put a wrench on them and make sure.

Bolts are all tight - usually you will get noise when you shift from reverse to forward - no noise forward.
The popping is just in reverse and almost feels like the left side goes up a little when you hear the pop. It's really just like a bearing out - it's just when there is no weight on the left tire and you rotate the tire forward and reverse it's all smooth and tight?

I would start by pulling off the pan and see if there was anything laying in the bottom. That will give you a good indication. If there are metal filings in there, it is definately worth going on to the next level. If not, I would remove the bearing covers from the final drive and visually inspect them.
