Thin grease in CV joint, NAC, but VAC

[Tihol Tiholov]

Haudi, gents.

A follow up question on my CV boot replacement saga. Took out a pass. side
suspected Chinese axle on the '92 Eurovan (shaft is 30 mm diam. vs. 26.5 on
the OEM shaft, splines for inner CV joint are also larger diam.). PO
installed this 4-5 years ago maybe.
The grease was running out a bit thicker than engine oil. Inner CV cork
gasket was in 3 pieces and it had sprayed the underside - reason for
intervention.

Does anyone have any BTDT or ideas why the grease is so thin?
Only thought I have is high temperature, but see no reason for it. The only
untoward thing was a loose plastic cap that I put back on the transmission
flange - it came out, when I pulled out the axle. Boots are both sound and
thinking of packing the inner CV with the OEM Molly grease I have and
reinstalling.
Can anyone recommend good Molly grease for CV joint, apart from the OEM
that I think is GKN brand.

Thanks for any advice and info,
