Hopefully the trans doesn't slip too much but if it does I've got an exedy clutch kit here that I can chuck in over the holidays. It'll do a mid 11 now so that should take out most of the oldens lol 2 Link to comment Share on other sites More sharing options...

Maybe the tcase is frigged. I'll get it off one day and have a look. It's spinning the tyres with least grip. Fitting a LSD or Truetrac will make a massive difference.

The rear isn't spinning so there is no point locking the rear, cos that's not the issue. I could lock the rear and the front will still spin cos the front and rear are split. 1 Link to comment Share on other sites More sharing options...

The split is 66:33 R/F from memory. Maybe the transfer case has problems. Link to comment Share on other sites More sharing options...

The pickup points on the gear for the front rear are the 60ish 40ish split in the transfer case, but there is nothing to hold them to that. If your car squats then more load is applied to the rear part of the transfer case gear assy, so it frees up the front part to send more power to the front. Google nv125 transfer case. Also look at the pictures to get a good understanding of it. It's basically an open diff that has more rear bias. I've researched it fully. My transfer case is working fine and haven't heard it jump a tooth for a while lol. Doesn't mean it is perfect but the only solution to sending power to the back is to lock the transfer case. This is only needed to launch the car from a dig. I mostly still get traction at any rolling speed. Link to comment Share on other sites More sharing options...
