Well. Decided to break some more parts at this weekends event.
I wasn't getting any wheel hop and had some small tires on that were just spinning like crazy with no effort. Then I heard a clank. Limped the car in to the pits nice and slow and drove some figure 8's.. No sounds.
Put the car on jacks and ran through the gears and all seemed fine. Got up to about 30-40 and kill the engine to let the tires spin "cant hear over straight pipes" and BOOM, wheels stopped and a brand new hole was formed in the back of my diff cover.
I was able to drive it up onto the trailer fine, but trying to back off the diff completely siezed up. I had to remove the axles to get it off the trailer.
Diff was a Tomei 2-way inside a S5 TII housing with S4 stub shafts.
I am hoping I didn't nuke the actual 2-way and just broke a ring or pinion "fingers crossed" I will be dropping it this week sometime
