The link above does not address the older Morgans (pre 1962). Is it assumed that I should use the info for those on 1962?
The earlier 3HA axle is more or the same as the 7HA in terms of bearings and seals. Dimensions are a bit shorter than the 7HA though
I've use 75/90 in my Salisbury axles with a bit of Molyslip.
PTFE tape on the drain and fill plugs.
Drain plug is a magnetic plug and is lock wired to one of the diff cover bolts.
Top tip is to keep the 3mm breather hole on the axle tube clear else the axle will pressurise and force the oil past the seals
Hope this helps
