You will also need a new 29 spline coupler. Again I sourced mine form E-bay. But yet AGAIN it did not come with everything I needed.
As delivered...
I noticed when comparing it to my 23 spline coupler that it was missing the center snap ring. This stops the coupler from drifting back and forth on the shafts and wearing out the front faces of the seals. So I went to my local bearing supply house and was able to find a snap ring that fit perfectly.
Installing the snap ring was a bit tricky. Finally had to get it set nice and square in the bore, then use a large socket to carefully tap it down into place. took a few tries to get it set right.
And hear is a visual for how heavy these beasts are....
