Good one. The soda-can shim thing might help here.
You didn't indicate how much time elapsed since your repair, but have you
been faithfully greasing the UJs? If not, first inject them with the 90w
oil (using a grease gun, like you use on the front trunnions). Then drive
10-15 miles. Re-lubricate using the proper grease...watch that the grease
comes out of EACH yoke.

More greasing for the bearings...
You may want to check both your rear axles for worn splines also (I had one
of these). If they are, you would see movement between the yoke and axle
(jiggle in two directions 90 degrees apart).

Better check anyway.

Trouble is, if those bearings were wobbling on the axle, the axle needed to
be replaced, as that acts as the inner race for the bearings and gets
damaged if the bearings fail.
As an incidental check, I would suggest you retorque the four bolts
attaching the brake backing plate to the hub assembly. These needed
attention on my car after I replaced my axle, and caused a brake
pulsation/vibration.

Sounds much more tolerant than Fred Thomas' wife... :-)
