http://www2.dana.com/pdf/J3311-1-HVTSS.PDFThis really is one of those times to go with an expert(Spicer) and follow what they say....
Just because you have never had a problem with a certain set up does not make it right.
I'll second that!
And we have a tech tip with the info direct from Spicer (Newest they have)
http://www.stovebolt.com/techtips/driveline/setup/index.htmlNot to step on anyones toes but It's hard to count the number of times I've read and received poor, incomplete, and/or plain wrong info about installing driveshafts.
PLEASE read the Spicer manual.
