Really? Zero play? That does make sense.

Mine you can move about .030 or more (1/32 inch) and they make sound. I'm taking about lengthwise side to side. Not a twisting kind of play. So in other words you can move then toward the wheel and away from the wheel, and that makes sound when it hits the end of its travel in each direction.

Somebody else here said theirs does that too.

if one side of the car is up in the air on stands. and you face and grab the wheel and move it up/down and left/right and in/out, where is the play (relative to the wheel not the car)?

the up/down play would only be due to the play in the spring as it is unloaded (just look and you'll be able to see if the spring is causing the play or not or slightly load the spring and see). the axles/shafts/cv themselves should NOT have ANY play (they shouldn't wiggle at all), they should only rotate.

[Lipshurt]

The play is on the axis parallel to the shaft. Parallel to the centerline of the shaft actually.

So not up/down
not forward/back
Not twisting

Only inboard/outboard.

Both sides do it.

that's not right at all. it shouldn't be moving. usually there is a pin right before the transmission that "locks" the cv/axle in place. it should pop and lock in but not wiggle in/out.

why else would 2012s have different part numbers than 2013s?

everything else related to steering/suspension/handling seems to match up between '12 and '13 besides the spring.

Not true. The CV axle will slide in and out of the output spline of the gearbox. If it didn't, there would be some serious drivetrain bind when the suspension compressed.

no, it should pop in and out, it doesn't just slide in/out effortlessly. there's a ring that holds it in place. drivetrain bind doesn't really occur because of the cv and hub assembly. if you compress the strut, the axle still isn't moving a whole lot. the CVs can bend and rotate internally (it has to for steering to work).

here you go:



regardless, it still doesn't answer why the 12s have different axles/cvs compared to 13s.

[revhigh]

Zillion is 100% correct ... otherwise it would rip the halfshaft out of the trans as it moved up and down with the bumps in the road.

Every halfshaft I've ever seen has that lateral play.
