Before i start let me say im in no way blaming this on the seller of the rear. just a disclaimer there. So i bought a used Strange 12bolt 33spline axles eaton posi 4.11 gears out of a 00 WS6. i was told the rear was never raced and only had around 2K miles on it. For all the break in use and dyno use the rear was fine, very quiet and shown no signs of failure or sevear wear. So i finally get to the track with the car and after 3 runs and 2 of those runs only launching at 4K its whining really bad on accel and growling really bad on decel. If i had to guess id say the pinion bearing took a crap, but i haven't opened it up yet. I was told numerous times that a s60 would be heavy and overkill for my set up and that a 12 bolt would be sufficient and this is what happens after 3 runs that weren't even that rough. whats going to happen when i dump it at 5K+. and i wasn't even getting good traction best was only a 1.8 60'. Im probably gonna fix this one and see what happens or is it not even worth it should i just fix it and sell it to someone with an auto that it might not break on and then get a S60. Just really suck that either way im out a crap load of money than if i just bought the S60 to begin with. Should have gone with my gut. any EXPERIENCED advice would be helpful. THanks
