It was causing my engine to miss. At the suggestion of an engineer friend, i took the driveshaft to a clutch and driveshaft company to have it balanced. I'm not sure how closely the factory balanced them, or if someone using the driveshaft prior to me had done something to get it out of balance. Anyway, after having it balanced, the vibration, and the high speed miss went away. Problem solved.</span></div><div id="yui_3_16_0_1_1434194137202_166955" dir="ltr"><span id="yui_3_16_0_1_1434194137202_166934"><br></span></div><div id="yui_3_16_0_1_1434194137202_166973" dir="ltr"><span id="yui_3_16_0_1_1434194137202_166934">Jack </span></div><br> <div id="yui_3_16_0_1_1434194137202_166782" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div id="yui_3_16_0_1_1434194137202_166781" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div id="yui_3_16_0_1_1434194137202_166780" dir="ltr"> <hr id="yui_3_16_0_1_1434194137202_166823" size="1"> <font id="yui_3_16_0_1_1434194137202_166790" face="Arial" size="2"> <b><span style="font-weight:bold;">From:</span></b> "toodamnfunky@comcast.net" <toodamnfunky@comcast.net><br> <b><span style="font-weight: bold;">To:</span></b> fot <fot@autox.team.net> <br> <b id="yui_3_16_0_1_1434194137202_166933"><span id="yui_3_16_0_1_1434194137202_166932" style="font-weight: bold;">Sent:</span></b> Monday, June 15, 2015 11:55 AM<br> <b id="yui_3_16_0_1_1434194137202_166789"><span id="yui_3_16_0_1_1434194137202_166788" style="font-weight: bold;">Subject:</span></b> [Fot] TR4 High speed driveline vibration<br> </font> </div> <div id="yui_3_16_0_1_1434194137202_166783" class="y_msg_container"><br><div id="yiv0583838431"><div id="yui_3_16_0_1_1434194137202_166786"><div id="yui_3_16_0_1_1434194137202_166785" style="font-family:Arial;font-size:12pt;color:#000000;"><div id="yui_3_16_0_1_1434194137202_166784">FoT,<br></div>
