Diff Tightness

[CraigM]

I ran my 511 for the first time on the weekend and it was great, I did have issues with the diffs slipping however. I was wondering what procedure most use for setting the tightness?

I know associated diffs are tightened all the way down, then backed off a turn, but the 511 manual seems to indicate that you run them as loose as possible without them slipping i.e. install the diff, then tighten until you can no longer make it slip

Thanks in advance
