Steve,
My guess is pinion-related also.
You're sure the U-joints are good and that the sliding joint in the
drive shaft is snug?
Was there measurable wear on the pinion shaft? We just did three MGB
thrust-washer replacements at a club session last week. All three
pinion shafts were worn greater than .005, and their wear was tapered in
the area where the pinions turned. We had two pinion shafts, so
installed them, and used again the least-worn of the others, in its
original axle.
