macattack Posted November 8, 2013 Share Posted November 8, 2013 just took a good look at the driveshaft on my mr688s truck and noticed this. i think i need to spin the drive shaft so the front half is in phase with the rear.notice the yoke at the trans is opposite the yoke at the power divider.pic 1 shows from trans to center bearing and pic 2 from center bearing to rear axle.

rsb502 Posted November 8, 2013 Share Posted November 8, 2013 yeah, unless you figured out a way to make that a three piece driveshaft you cant change the way its mounted, other than rotating it 180 but I dont think that will do anything.

rsb502 Posted November 8, 2013 Share Posted November 8, 2013 I don't see a slip yoke in there anywhere, am I missing it somehow? or is there more than pictured?

felicello122 Posted November 8, 2013 Share Posted November 8, 2013 It's in right, the carrier bearing yoke and the power divider yoke are lined up, the one on the trans. Will be the opposite.

macattack Posted November 8, 2013 Author Share Posted November 8, 2013 i thought the yoke at the trans and the rear diff yoke are suppose to face the same way.

Vladislav Posted November 8, 2013 Share Posted November 8, 2013 Yoke's orientation is an important thing and is determined by shaft's working angles.It's made some special way when engeneering the vehicle and must be used the way as from the factory.So if you think that must be all in line it's not true.

mack4ever Posted November 8, 2013 Share Posted November 8, 2013 i think al the yokes on the shafts are to be in one line.so there is one yoke 90 degrees of.

Freightrain Posted November 8, 2013 Share Posted November 8, 2013 With the slip yoke in the middle, your two far ends will be 90* out. NO way around it. As long as each single shaft itself has the ends lined up it(especially with a slip yoke where someone might split it), you are fine. Quote Larry 1959 B61 Liv'n Large......................

gearhead204 Posted November 9, 2013 Share Posted November 9, 2013 to my knowledge this true on all drive shafts, the exception is on steering gear then the yokes must not be in time with their respective yoke Quote Link to comment https://www.bigmacktrucks.com/topic/33416-does-this-look-correct/#findComment-215767 Share on other sites More sharing options...
41chevy Posted November 9, 2013 Share Posted November 9, 2013 With any 3 piece shaft with a slip joint, the universals on each shaft will be at different locations. THe hanger bearing acts as a termination point for the front shaft and a starting point for the rear shaft. What is important ins that each yoke on each separate shaft are in phase with their mate. It is impossible on a 3 piece shaft to have all of the joints match.

BOB DINGSDALE Posted November 9, 2013 Share Posted November 9, 2013 if you put all grease fittings in line you will be in time and in phase 1 Quote Link to comment https://www.bigmacktrucks.com/topic/33416-does-this-look-correct/#findComment-215832 Share on other sites More sharing options...
