So i bought one of the EMPI ones from Rock Auto
NOTE FOR EVERYONE:
In my search for the correct spline count, I soon found that it was an elusive number
SO here it is. For an SVT FOCUS the spline count is 34 inner/25 outer.
Note that the outer spline count is the same as any other focus due to similar knuckles.
In terms of the shaft itself, seems to work great, easy to install, good price, shipped fine, new shaft with no core charge, cost like $80, yadda yadda, rock auto is a great thing.
I'm still having other sounds though and they worry me.. I believe it is like bd8134 said, My dad and I over tightened the bolt and pressed the bearing, now we are having issues finding that sweet spot. In the mean time, i think the bearing is bad anyway and needs to have a new one pressed in.
