lubrication verification
(OP)
On a production line, we assemble wheel hubs to axle spindles for heavy duty semi-trailers. Then lubrication is added in the form of 80W gear oil or semi-fluid grease. Problem is that after solid hubcap is assembled, how to verify that the lubrication has been added. This issue is very serious due to the lubrication being essential for operation of wheel bearings. No lube = melted bearings and spindles = catastrophic wheel failure. Wheels flying off a tractor trailer loaded with two steel coils is something that we want to avoid. Is there any method of checking this - examples UT, flow metering?

Can you test to determine if it sounds or feels different after tapping it with an object; brass or aluminum or etc..?
If I remember right those "bearing buddies" were see through to visually check for lube.

How about using a "LUBED?" punch tag taped on the axle that must be confirmed as punched in order for the next part in the assembly operation to progress?
