If you hear a barking sound and can feel grinding when you hold the wheels then the diff is too loose.
If the front wheels dont come off the table at least an inch tighten your slipper a quarter turn. Check again and adjust until the front wheels come off the ground about an inch or two for loose tracks, and 2 to 3 inches for high grip tracks. Works for me.
Thanks, zf..
Yeah I was referring to using the slipper trick (holding the wheels and gunning to get 2-3" of lift in the front) in my earlier posts. I wasn't getting lift, and started to hear the diff slipping (so I stopped immediately). I believe you've confirmed my suspicion that the diff is too loose. I'll tighten a little and see if that gets the front to raise properly.
I never had this issue before, always was able to tighten the slipper nut until the front raised.. The nut was usually about 5mm past flush (yes, 5). But, I just rebuilt my diff, broke it in, can lightly flick the rear wheels and they spin 1 revolution. I thought this was money. But when I went to set the slipper, this weirdness ensued. Won't slip, won't lift. I thought it had to do one or the other.
Like I said, I'll tighten the diff a little and test a few times to see if that's the issue. If that doesn't do it, I'll have to just starting drinking. More.
Right now the car runs great (turns very well, seems to have plenty of get-up and go) but I haven't been to the track.
