<div id="yiv1756558952">
<div dir="ltr">What is the trick to get the two sets of OD splines completely
aligned? My Bentley manual (GT6) says to use a long screwdriver -
fat chance. I even milled a piece of steel flat stock to mimic two
opposing splines of the trans mainshaft with a taper/lead-in on the tip.
I have gently tapped the flat stock but the second set of splines is
still offset by about 1/16 of an inch and does not want to rotate into
alignment. I did not do any service of the OD other than to rinse
and flush out the inside of the OD - not sure how the splines became misaligned.
