Hi guys, I'm having trouble with the plastic diff in my F104. Like normal I took the wheel off, put it back on and went to set it up again, however something has changed and it no longer functions like normal, the two rear wheels lock together straight away, and I can't do anything about it. I've tried everything, cleaning it, re-greasing it, re-assembling it, but I can't solve it....any ideas???
And yes, I will be getting a pro shortly...
