Canada 2000 Defender 110 Td5 SW Bonatti Grey
leaking rear axle seal
Saw a puddle starting to form on my right rear wheel... obviously this is NOT good. It's been a tough couple months for my truck (and for me).

Being that I moved to a rural area, it's a 4 hour trip with a 2 hour ferry to get to the local LR repair shop. My 110 was there for WAY too long to diagnose a running issue, which they couldn't figure out. Turns out I had them check the CPS and it was the culprit. * weeks later I get the truck back, first day, starter solenoid pacs it in... 2 weeks to get the parts... so now I'm up and running again... 2 days later... now I'm trying to figure out how I'm going to get over this hurdle.

So, if I am going to try to tackle this, I'm assuming it's the seal, and if I'm in there I should probably replace the bearing. Does anyone have a list of parts required? I'll need to order everything in, or should I just trailer it back to town at about a £250 expense to get it done?

Looking for opinions and options.

It certainly looks as though it is leaking from the drive flange to hub joint. There is usually a paper gasket on this joint, and it is quite a popular leak. There is actually no reason why you shouldn't use a good jointing compound (such as blue Hylomar) and dispense with the gasket, but be very careful not to get sealant down the bolt holes, since this can cause all manner of problems (they are blind holes and it is fairly common for the bolts to shear).

There is absolutely no reason to suppose that you need new wheel bearings if it is the drive flange leaking, and there is no point replacing them if they are sound.

I would only replace the bearings when there is play on them.
And as you have a td5 you probably have a spacer between the bearings. You can change that to a double nut system (say upto 300tdi). With the double nut system you can adjust the bearing play out.
There are plenty off posts about that on this Forum.

It is difficult to see where the oil comes from on the picture. If it comes from between the drive-shaft flange and the hub. I would take the flange off and clean the mating faces from the flange and the hub and use some liquid sealer to seal it.
You can add some bearing grease if needed. Roel

It does look like leaking from the drive member. If it was a hub seal leak, I would expect the oil stain to be further inside the rim.
Already got the advise above. What was missed out is that it is a simple job, and you do not even need to remove the wheel. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

Re: leaking rear axle seal
Those flanges look beefy, but the issues will be same as OEM. You can seal it up with a good quality sealant like Permatex “right stuff” or most any good sealant (not silicone). Remove the flange and apply to the surface (after you clean it). Canadian Tire has what you’ll need.

Good luck

Check your axle breather is not blocked.

Excellent feedback, exactly as I had hoped. They are KAM flanges I had installed about 5 years ago. (I hear their current product offerings are not the same quality).

I'll clean up the oil, check the breather and see if there's any more leakage. Next step will be the flange gasket replacement. it's a Landrover thing...
