Hi Cline,
I see that the driveshaft manufacturers recommend these yokes with shorter barrel lengths for 4L80E applications even with the 24204289 output shaft being used. Their reasoning is that that the longer the yoke is the further away it puts the u-joint from the trans bushing, which can cause play and wear the bushing out faster. Any truth to this in an application where the Sonnax no walk bushing is installed backwards and the properly sized bearing is used to rollerize the output? What would be the draw backs of using T3-3-2431HP or U1664 yoke with shorter barrel length of 3.650" or 3.880" vs the T3-3-5571HP that has a barrel length of 5.380" when using output shaft GM 24204289 in a rollerized application? To me, the more contact the barrel has with the grooves on the output shaft, the better, no?
