Does anyone else experience rear diff case pressure buildup? I've looked for a vent but I haven't found one. I can unscrew the dipstick and I release quite a bit of pressure. I'm thinking I'll just put a breather on a M22x1.5 plug. Anybody have any suggestions? Thanks

Page 176 on the AGCO parts book website shows 2 vents. Yours are probably covered in oil and dirt, preventing them from doing their job.
