Maybe......I have done it, but....
I can only speak from my own experience.
In my opinion, the problem with the Grover 2-band 4:1lies more in the design than lack of lubrication.
First - the assembly is swaged together and if disassembled is not likely to ever go back together. I have been able to force light grease in to the things with hydraulic pressure after soaking in solvent, but the results were minimal and the "catch" problem still existed.
That 'catch' I have found, is due to the large central compound gear that was originally fit loosely into a machined bore in the case. The offset load placed on this piece by the pinion gears above and below acted to cock or tilt the piece in its bore causing it to jam.


Once worn to this point, no lubrication seems to help this binding misalignment.
At least this is my experience with them.  Continued attempts to force their use eventually destroys them.
On original banjos, I remove and safeguard them, replacing with new high quality functional machines.
The Stew-Mac Waverly 2-band simulates the appearance by means of an offset case, but the internal works are 4:1 planetaries - a much more dependable design.
