Axle breather & oil query

Obi_110 · May 9, 2024

Morning all,

The breather on my front axle is knackered, I suspect the rear breather is too - I've got a 1990 Defender 110 that started life as a V8 (Salisbury on the rear) - can anyone advise the part number for the breathers?

Also, what's the correct oil for the axles? I figure I might as well give the old girl some fresh oil while I'm at it.

Thanks in advance,

EP 80/90 oil. Axle breather kits available on line. Chasing part numbers for items like this can be a pain. Check with supplier if sutable.

I believe the breathers are a 1/8BSP fitting.
I use 8mm PU tubing and push fit connectors.

I'm in the middle of fitting this to both axles and the gear/transfer boxes too.
Consequently I have removed the old 'breathers' which I can send you if you want to stay with the original style ?

How are yours 'knackered' ?

Axle oil is EP80W-90

Thanks - the breather pipe is missing on the front axle and I think it's blocked up, there was a little bit of pressure when I opened the filler plug and a bit of leaking.

The rear axle seems OK and the breather pipe is intact, but I thought it best to do both at once.

The original seem to block up really easily.
Mine were blocked when I took them off the other day, it was about 3 years ago when I last checked them.

Mine going in ...
The rear runs along the axle, up the A frame, along the chassis under the driver seat and up to near the clutch master.
The front along the radius arm and up behind the front inner wing, along the froint of the seat box and across the top of the bulkhead.

Work in progress ...
