What is the deal with the greaseable and non front hubs? I know the ABS and non differ but there is a note about
mismatched front hubs and differing wheel seals in the service history on my 90 I recently bought.

 

I'm not sure what's going on in/with this...
What do ya need?

 

All the XJSs had serviceable non-sealed bearings. I think the hubs (and seals) were different in the ABS-equipped cars.

Non-ABS cars had a zerk fitting in the hubs for external greasing. Not sure if this was carried over to the ABS-type hubs

What I've been told is this ABS equipped 90 has two different front hubs that take two different types of wheel seal.
I'm curious what if any functional difference there is in the two different hubs/seals. Meaning is it worth
my time to try to run down another matching one of either type? I had read online that the grease fitting
was a quick way to tell them apart from the outside but that may not be the case.

 

Ok, did front wheel bearings on the 90 today.

Passenger front has a zerk fitting on the wheel hub and takes a fairly standard drive-in type seal.
Diver side has no zerk fitting and took the big weird rubber seal that affixes to the spindle and then you install the hub/rotor.
The seal types appear to be specific to the wheel hub. Luckly I'd taken a guess and managed to have a set of both (plus a 3rd
completely wrong option that came with the SKF bearing kits, way larger seals). These are both on an ABS car and functioning, so
that isn't the difference (is it?)

Which one is the newer/better version?
The standard seal type was certainly easier to deal with, and easier to judge wheel bearing tightness as well.


Both sides had signs of water intrusion and had a looooot of miles on them(75K or more). The bearings were clearly due to be replaced but I've seen far worse.
I don't see that either style seal did any better than the other though the rubber one was completely frozen to the spindle and came off in pieces.
Both stub shafts are a bit worn, cleaned them up and will replace them later.
Car has way north of 200K on it, so it's expected.
