the breather tube is super easy to remove/replace/modify
mine kept clogging and building up pressure in the diff. i ended up installing a small breather filter (like some use in place of a PCV) a little higher up than the factory one.
in your case i would probably do a combination of things.. maybe run a longer hose up towards the front and put a filter on it so that nothing can get in to clog the longer hose
good luck with it!
