Rust in Diferencial casing
Posted: Sun Jul 05, 2009 1:53 am
Hi all,
I pulled my front diff cover to find the right hand bearing cap and upper indsides of the diff cover coated in furry rust, a kind of mouldy Iron Oxide!, I run free wheel hubs so the the diff hadn't been turned for a while.
The oil wasn't as nice as 3 years ago when it went in fresh, but there didn't seem to be any water contamination in that oil.
I suspect the breather valve has been letting moisture in but not out?
Any other ideas greatfully recieved.
has anybody got a digram of the insides of the breather valve?
Thanks,
Dave.
