Birf soup? HZJ73

driver side, heard my first click turning into my house, pulled in, took a look and saw this.

my mud research indicates possible inner seal fail allowing diff fluid to mix with knuckle grease?

Thanks!

Yes you need to change seals, etc. and repack. I would think that Cruiser Outfitters would have the entire kits for your 73 ready to go.

This is the Land cruiser ownership initiation rite, ahaha. Lots of 'fun'.

If you still have e-hubs, you should consider going to manual hubs when you do this job. Just find spindles/hubs/freewheel assembly plus hardware from an old 60 series. Or buy from Cruiser Outfitters.

Thanks, PO put in manual hubs

This appears to be the one, I'll double check before I order.

Is the Marlin inner seal recommended? Thanks

Marlin inner seals for 40 series are awesome. For 80 series the consensus is they blow out too fast. I had one last only 10k miles.

I don't recall that I have heard much about the 70 series seals. I would tell you to call Cruiser outfitters and they will be able to give you advice.

I used the Marlin seals... seem good quality.
Still not leaking.

A common cause is plugged axle breathers. So make sure and clean those while you are at it and that they are no plugged.

Cheers

is there a access point to get some moly in the knuckle in the short term that does not require pulling it off? I don't see an access plug. thanks

Let us know if you decide to make one.

took a look and saw this.

Certainly not the worst one we've seen on this forum. On my 73 series you couldn't see the trunnion bolts when I got it from the PO
There is a few videos on youtube if you haven't done one before.

hehe is that a thing? making your own hole and grease gunning some moly in?

There is a square plug on top of the Birfield housing. You can pull it and put some grease in. Use a zip tie or something to check the depth. You normally want it something like 2/3 full. It's not directly on top but off to one side.

I just blew a marlin seal after about 10000mls. measured the new and old marlin seal and was fraction bigger than axle. measured new Toyota seal which was fraction smaller than axle. Should have written measurements down anyhow gone back to factory seal. This is third leak in 3yrs all after using after market seals. One leak was seal damage from installing axle through seal so take yor time and be careful of seal.
