I wonder how much new/second hand stub axles are?

Hey Rick,
thanks for the hint...I will try the part # with another dealer (other than where I'm working at the mo) and hear what they reply...

Just to clarify, I believe Rick meant that the RTC351 is still a currently available seal.

Not that it is used by rover in current defenders.

Because rover use a different seal now, does not mean it seals oil, water or dust better than the RTC351 used in the past when the bearings were oil lubricated.

I think there're some FTC4785 seals on the shelf,
I may try to open one and see how's the seal inside...

Then ring another dealer as planned...

that seal (FTC4785) doesn't have any springs to energise it Michele. It won't work as an oil seal (or keep water out, for that matter).

New stub axles were quoted $145 +gst (each) and I never bothered to get a genuine price.

One can replace the bearings but they are not cheap and you will need a bloody big press.

I'm now convinced that I should convert both the front and rear hubs to oil feed on a Defender, but still have a few questions.

• Replace the grease wiper with the double lipped oil seal (Corteco P/N 15510067 or Rover P/N RTC3511 <A>)as mentioned above. is this (7) on the diag?

Also from the diag, (7) refers to "inner and outer hub seals." Are both these seals replaced by a single RTC3511 oil seal?
There is no mention of replacing the seal on the spherical housing, so is it ok as is?

For the REAR hubs,

1. is there an "axle shaft seal" (similar to 8 on the diag) to be removed,
2. do I remove the "inner hub oil seal" (as per Defender Manual Sect51 p41), and
3. replace the "outer hub oil seal" with the RTC5311 oil seal?

Thanks
