Ras!
I am fitting FRC4320 stub axles all round which are old 90 front units that accept AEU2522 CVs, however I was planning to use my original disco 10 spline hubs.
Turns out 90 10 spline hubs are different to disco 10 spline internally and aren't interchangeable!
well, the inner bearing is in exactly the same position on all versions of conventional 1986 onwards coil sprung landy hub
the outer one however changes position
the earliest hub i know of is the early defender type with the thick drive flange
this hub only has one seal, the inner, where RTC3511 is preferable
this means that with only one seal, the outer bearing can be as far out as possible, as far as the stub axle will allow with space for the two nuts etc
defender hubs changed on KA chassis to a different type of stub axle, which may or may not contain an AEU2522 cv joint, thats difficult to say at this point!
however, all defender up to 1994 had a single seal in the hub
disco 200 was a different setup again, with redesigned hubs using a more low profile drive flange, probably with alloy wheels being the main reason to consider the modification
these type of hubs have 2 seals fitted, and seeing as all hubs have the same external dimensions regards offset between the rear face, the rear bearing, the wheel mounting face and the outer drive flange mounting face, the only option is to move the outer bearing inwards to allow room to stack a seal on top
instead of having the bearing directly beared on by the tab washer and first big nut, there is a spacer type thing which acts as a seal land for the outer seal, this is about 10mm thick so the bearing is moved in about 10mm accordingly
this outer seal was fitted as an attempt to separate axle oil from the bearings which were then clearly designed to run in grease
luckily this method didnt work too well, which means that 200 disco hubs get nicely oiled and last a very long time compared to:
300TDI hubs!
which are by far the runt of the litter
these have the unholy idea of a stub axle seal which makes a great job of keeping the bearings dry and horrible
they are also the thinnest hubs by far, land rover again moving the outer bearing further in and ditching the outer seal in favour of the stub axle seal, which unfortunately worked a lot better!
as such, bearings moved close together, no outer seal and thin drive flange makes for maximum alloy wheel clearance and wheel design freedom
bad for bearing health though!!
thus, i decided the best option was old fashioned defender stub axles with AEU2522 cvs which are also land rovers best
i didnt know that the hubs were different so to now find out the bearings are even wider spaced on early defender hubs makes for an even greater result.
just need 4 more of the buggers now cos ive had to borrow the two i fitted today!
i still put grease in hubs but oil will work its way through
