Urgency of replacing hub seal

When I got to work this morning I noticed a 'spray' of oil on my right/rear wheel. Nothing heavy, but considerable. Based on searching the forum it appears to be a blown or weak hub seal. How urgent is it to replace this seal? Risk of seizing? Wheel falling off?

I ask because I leave for SAE (the longest highway drive yet in my truck) and am not sure I'll have enough time after work to fix it... much less find a seal in 24 hours to replace it. Is this a deal breaker? Thanks.

Check your axle breather line. Mine got clogged, pressure built, and forced grease out of the hub seal coating the inside of the wheel. This was with one week old Defender hub seals. So it may not be your hub seals but the axle breather.
On my D1 I was able to unscrew the banjo fitting on the axle and blow compressed air into the fitting and through the line. A big chunk of dirt came out of the line.

Disclaimer: I have a D1 and I am not 100% sure about the axle breather lines on your truck.

x2 the drive flange is where one of mine leaked.

Took about 8 min to repair with a paper towel and RTV

If it is on the outside of the wheel it is likely the drive flange. CHECK AND MAKE SURE THE BOLTS ARE TIGHT BEFORE YOU GO ANYWHERE.

I think I have the same thing going on here. This is all on the inside. I just realized it the other day. I am considering the Georgia event tomorrow. Is this a bad idea?

Clean the axle breather, I cleaned both mine front and rear with brakleen and I haven't had any issues since, both were clogged.

In my 4runner it actually pushed oil through some rusty parts of the housing because of the clogged breather.

Just check the level in the swivel and make sure the brake is clean and you'll be fine. Mine have coated the rim in oil in the past and it's been fine so long as the levels are ok.

OP, are you running oil or grease in your hubs? Regardless, you'll want to check the oil level or repack with grease depending how much came out.
This is where mine was leaking from.

General rule of thumb, if oil/grease can come out, water can go in. Once water gets in the hub you will be replacing bearings.

But if you dont care about that, drive the piss out of it

Unless you drive off road where there is any amount of wading involved....

From what I gather, it's ok in the short term for the short term, if you're not doing any wading and keeping your diff fluid topped off with 90 wt. I just developed the exact same problem so that's why I ask.

If we are talking hub seals it doesnt matter if you keep your diff fluid topped up if you have stub axle seals. The water will get past hub seal and wash out grease and rust bearings in no time flat. I have had this happen. You will be cleaning up rusty bearing water/oil at least an hour.

If you dont have stub axle seals the water can get into axle housing and diffs. Water and oil do not mix and it can run your diff bearings, and cause poor lubrication of ring and pinion..You get the point.

Moral of the story????

Replace the $5 hub seal!!! and stub axle seals unless you're running oil bath hubs.

You Defender guys own $20-50k trucks, for the love of god take care of them!!!!!

Disposable discos don't. Run it until the wheels fall off, sell it for scrap, buy a new one..... Repeat

I had a D2 prior to getting this so I'm familiar with Rover ownership. I'm planning on replacing the gasket, just do not have time before I leave for SAE and wanted to make sure I'd be fine

If I replaced every weeping seal, I would be broke!

Mine are not leaking enough, nor do I wade deep enough or often enough to worry...
