Dude?!? I am not a dude...

I also have a 1600, MK1. Unless you have a Deluxe or TwinCam the front 
suspension/hub bearings are the same.

The #43 I am referring to is in the Moss Motors parts diagram. #41 is the 
same item in the MGA workshop manual page K2.

If the bearings are not a tight (very tight) fit into the hub then the hub 
is worn. The shop manual advises to NOT remove the bearings unneccesarily as 
this wears the hub's machined surface and then the bearings no longer fit 
tight in the hub. Replacement of the hub is the fix. It might be possible to 
use a Locktite product to glue the outer race in place. Google Locktite 
Bearing Mount.

That refers to the steering rack, not the swivel links/kingpins. It is a bit 
confusing - see the workshop manual; figure P.1 section P.2 "Steering Gear 
(C)". The "C" refers to the chart of lubricants - item C is grease.

Section P.4 "Steering Gearbox (B)" is indeed hypoid oil for the steering 

See "Lubrication Chart"
