Grizzly Engine & Transmission Swamped December 4, 2015 So last weekend I swamped my grizzly. Iam on number 4 oil change and still milky. My question is my diffs are milky also. Can I flush them with diesel fuel or some thing to clean them out? Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
