Does Everyone Have a Front Axle Leak?

[Rob-D]

Almost all oils have seal swell additive. Apparently, this additive gets used up or changed in service such that the lip seals shrink a bit. New oil has new seal swell additive that "livens" up the seal again.

Yes, but that's a stop gap measure. Why do we need to swell the seals, what's wrong with this picture?
Deere has specific fluid maintenance intervals,what happened to them?
Again, seals fail because bearings go bad or because internal pressures push out the lubricant. If you look at the tranny you'll see a vent on top, maybe the front box needs a vent?

Don't have the manual ,does it have a vent?

Does this stop the leak?

 

[arrabil]

I'm thinking it prevents the leak (outside of bearing failure related leaks).

 

[Rob-D]

OK, that's getting somewhere because it means the leak is due to pressure from expansion.

Has anyone here replaced their own seals using a SKF (CR=Chicago Rawhide) brand unit? Is the oem part a nitrile seal or viton? viton being more resistant to chemicals

Has anyone contacted Deere? After all these problems there must be a solution. Is it just to make sure your levels are up and how long does it take before they drop to the point the porblem has to be addressed?

Ask and you shall receive.
JD2520 Two years ago, a day or two prior to expiry of warranty, left front seal, heavy seepage (small puddle on garage floor).
Four months later, same thing, same wheel.
Been OK since.
