Rear End Lock - ZR-1 Net Registry Forums

tf95ZR1 · 05-30-2006

Since I'm at work I'll try some keyboard diagnostics before tackling my problem.
While going about 110

without any warning my rear end locked up like I hit the (rear) brakes. I reflexively pushed in the clutch and put it in neutral and slid off to the side of the road safely whew!

I then found that I can only go backwards in reverse normally, but not forward. Any forward gear, slowly letting out the clutch results in no forward movement and boggs the engine badly.
Someone said its the differential (4:10's) where forward the pinion locks out but reverse it "seats." Someone said its the trans as reverse is on a different spline?
Any experience or any ideas?
TIA

PS. Easy to back up onto a trailer, hard to remove half shafts to roll back off!
