I have a 741 case 3.55 sure grip I just pulled out of my dart. The gears do make whine. I'm not sure why or what is causing it, thats how it was when I got it. The pinion seal leaks and will need to be replaced. The suregrip worked great and the diff is useable as-is. I removed it to install a 742 I have with 3.73 gears.
