Hey guys, I've searched pinion angle on most of the popular formus but haven't found much specific to 03/04 IRS'. I've heard that 2-3 degrees is acceptable if you have urethane bushings (which i do) but is that up or down? i noticed the pumpkin has a bit of an upward tilt to it so i hope it doesn't have to go down the other direction. i know once i get the pumpkin set i should be able to match that angle with the tailshaft of the trans and most all vibrations should go away. i just need a good starting point...anyone know? i appreciate all the help.
