Also never had to correct a pinion angle after lowering. Pinion angles should be anywhere from -1* to -2 1/2* This is always what we use as a reference and lowering a stang will not effect the angle enough to even worry about it. As it is so slight it is not worth talking about it. Normal drops on a stang are 1 - 1 1/2 inches which will not change the pinion angle enough to even talk about. Just saying The yoke posted was not a pinion angle issue. Unless it was from a monster truck raised through the moon.<br /> <br /> <small>[ 2014-06-05, 06:10 PM: Message edited by: Tom Renzo ]</small> <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Duncan Motors</b> <br /><small>Member # 7045</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2014,5,5,19,54,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> on this type of ford i have and they do, its not even a discussion. not sure what models fords you've referring to as of done, but the upper adjustable arms fix it on these model cars. <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Tom Renzo</b> <br /><small>Member # 13165</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2014,5,6,2,43,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Upper arms fixes it on every car! just saying lowering it as i explained does not change the angle enough to even bother with it. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>racsirx</b> <br /><small>Member # 1710</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2014,5,6,8,50,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> I just can't believe it was the balancer and it was doing it just in certain rpms, I have had them do it down low or seem like a motor is completely coming apart, most of the time when a customer complains about a vibration that comes and goes at different rpms and I pull the driveshaft out and see a bad yoke, it's pinion angle, but changing pinion angle is a good idea any ways since it helps with traction <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
