First time posting in this thread. Couple weeks ago I changed rear diff fluid and put magnetic drain plugs from goldplug.com High quality stuff, also installed one when I changed my oil around the same time. Planning on changing from diff fluid and transfer case fluid soon (already got the magnetic plugs for those as well).
Installed an AVIN Avant head unit in my X! Check this thread out for photos.
