2005 AC 300 4x4 green, a while back the left rear axle broke in half, well, pulled it out replaced it thought it was done. fast forward to now, had engine work done since it was smoking, wiseco piston and rings, bored and whatever else he did, and it runs awesome.

I would previously have to add oil here and there but that was because oil was getting by and well that was fixed. Get it back from shop, oil was low, add more, ride it, check it next day no oil. what the??? ok fine I always take fluids when we go camping so fill it up, next day empty...anyway wasn't until i parked it on cement there was all my nice clean oil in a puddle coming out of where axle goes in. I'v been searching the schematics and cannot find a seal or O-ring or anything that needs replaced where it inserts into gearcase.

Can anyone advise please????

Thank you

#28 is a seal but I have no idea if that is what is leaking.
I'm not familiar with that machine and without knowing the design, that's as close as I could help.
Good luck.

 

Are you loosing engine oil or gear oil?

 

Thanks for that info, i was thinking thats internals but it looks like what i needed.

And Zrock its engine oil, its not a seperate rear diff as in larger machines.

 

After you replace the seal, check if there is a plugged crank case vent. Base pressure probably gets vented to the air box. I've seen on other motors where the crankcase didn't vent properly and it blew out rear main seal.
