Anyone have seepage from the seals on your rear diff or blowing out the seals? A buddy of mine who raced his 650 kept having issues with the seals even after replacing them twice so he ended up installing a vented catch can for the rear diff at about 500 miles and now has 3500 miles with zero issues with the diff. I noticed some seepage on my XTZ and also noticed the vent bulb completely expanded and very hot after a hard ride. I am currently in the process of adding a vented catch can to my XTZ for the rear diff and will have some pics and results soon. Hopefully something like this will resolve the diff issues with our cats..
