I thought that this was odd, but my driveshaft is the exact same angle after the SYE install as it was before -- 19 degrees. Shouldn't this angle be 15* or less, or is that just for stock driveshafts? I went with the Advanced Adapters HD SYE and double cardan driveshaft from Tom Wood. I didn't install axle shims due to time constraints, and am now wondering if I should go with a larger shim than the 6* ones that Tom sent with the kit when I do install them.
My pinion angle is 9*, so it sounds like 6* degree shims would only yield a total pinion angle of 15*. I also understand that if my driveshaft is 19* that my pinion should be 17* to account for axle wrap under acceleration. It sounds like I may need 8* shims instead, but my question is: when you shim up the rear pinion, does the driveshaft angle also decrease somewhat as the pinion is raised? I mean, if I use the 6* shims, is it possible that it may raise the rear of my driveshaft up slightly to where it might be in the 17* range or so? Or would it remain the same 19* that it is now regardless of the pinion angle?
If I have to run the pinion at 18*, will it have oiling problems? It's an 8.25" in a '96 XJ.
