It is OK if the driveshaft is not parallel to these lines. So if the rear of the trans is tilted down 6.5 degrees then lets say the driveshaft is level, the front U-joint operating at a 6.5 deg angle will cause the driveshaft to speed up and slow down as it rotates. If the nose of the diff is tilted up at the same 6.5 deg, these velocity oscillations will be cancelled out by the rear U-joint and the diff pinion will rotate smoothly.</span><o:p></o:p></p></div><div><p class=MsoNormal> <o:p></o:p></p></div><div><p class=MsoNormal><span style='font-family:"Calibri","sans-serif"'>When you say the diff is tilted downward at 5.5 degrees do you mean that the nose is pointed down? This would be a bad situation as the oscillations of the driveshaft would be exaggerated rather than cancelled by the rear U-joint and you would have nasty vibration. Hopefully your diff nose is pointed upward 5.5 deg. This would place the imaginary lines within 1 degree of parallel and close enough for smooth operation.</span><o:p></o:p></p></div><div><p class=MsoNormal> <o:p></o:p></p></div><div><p class=MsoNormal><span style='font-family:"Calibri","sans-serif"'>Richard Good</span><o:p></o:p></p></div><div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'><o:p> </o:p></span></p></div><div><div><p class=MsoNormal style='background:whitesmoke'><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> <a href="mailto:damys@charter.net" title="mailto:damys@charter.net

The rear transmission flange is tilted downward 6 1/2 degrees. The diff is tilted downward at 5 1/2 degrees. The difference is 12 degrees. Is this too much for a universal joint setup to manage? We've considered raising the front of the diff, but then the spring will be twisted and we don't know how this will affect the rear suspension.
