Roman,
I can back up Jeremy's experience with the inner axle oil seal from Milners.
I have heard of several other instances of these failing prematurely, though
if I recall correctly Jon Wildsmith has had better luck with them. I suspect
this is to do with the precise alignment of the axle casing and knuckle, and
the amount of play in the swivel bearings and cv to driveplate splines; more
wear/play here allows more movement of whole cv and hence more movement of
the inner axle where it passes through the seal. The relatively inflexible
Milners seal can't cope with much (any?) movement, whilst the Toyota one has
a much more flexible design. This wear/play/alignment issue may be why
you'll hear from some people that their spindle bushes are completely
untouched while others will see wear in them. It may also be why Toyota
extended the driveplate splines from '93ish (?) onwards.
As for the other front axle seals (swivel and hub) from Milners, these seem
to be fine and are certainly much cheaper than OEM.
