Sorry for delay on some details about the track trip, was having issues with my personal PC and work PC has Imgur blocked. Didn't want to put all these pics together on the Iphone so just waited it out.
Track trip as mentioned before went well. Car ran back to back 9.8s at 150.
Ended up hurting the diff on the first "hard" launch. Didn't have any wheel hop but it was making plenty of noise after the pass. If you recall i had issue with diff before, took it all apart and it was in top condition. This time that wasn't the case.
Noise wasn't intermittent like before, it was ANY time the car was turning and diff was required to function. Ran the second 9.8 with it making a bunch of noise and then a final pass where it did get a little wheel hop and that surely finished it off.
Jack the car up in the garage and drain the fluid:
As soon as the plug was out i hear metal hit the pan! This to me was good news as last time there was no evidence and frustrating with no obvious cause. Magnet pulled this out, there wasn't many pieces but there were more than none...
Well time to pull the center out and take a look.
Passenger side wheel comes off no drama. Driver's side however...
WTF...You can see the look on my face in the lug nut as well...This isn't good...
Couldn't get a socket on 3 of the 5 nuts, all bent but 3 so much that socket wasn't going on...What to do?
I can access the axle retainer, so lets pull the axle and wheel together, mission Save the Forgeline starts now.
SUCCESS!
Those axle splines look healthy....Again only happened to the driver's side, passenger axle looked fine.
Now the unpleasant activity of drilling out wheel studs...
First one down.
All done, wheels is in top condition. Luckily.
Diff gets pulled and inspected:
First check, I cant see anything wrong with it. Concern builds remembering the last time. Till i spot this. you can see in the small hole the end of the pinion gears in the diff, and i see some metal in there.
Time to pull it down further and inspect. At this point with a damaged axle, I'm already convinced to upgrade. Now I want to see it for curiosity/research purposes.
