Play in Driveshafts?

[BoostCreep]

I have a slight but noticeable “roughness” or “vibration” that I feel in my gas pedal, mostly at freeway speeds, 60-80. I was looking at front and rear driveshafts today and noticed there’s play in both of them at the transfer case ends, and can feel it if I apply pressure as in the pics below.

Can someone tell me if this play is normal? @FordTechOne maybe

You should have some play to allow for suspension movement.

I mean there’s plenty of articulation in the u joint and the axle slips in and out of the transfer case to allow for movement, but I wouldn’t really expect vertical play. No?

Without grabbing your shaft (giggity) it's hard (also giggity) to tell how much play you have in your yoke (I'll show myself out).

The rear feels like it has less than the front, the rear feels like maybe 1-2mm or so. Front feels more like 3mm.

And that’s vertical play in the yoke for the rear, and the damper or whatever it is in the front I’m pointing to in the pic.

Doesn't sound like much, but I have never measured my shaft play (sorry, this thread to too easy).

Try rotating your tires and see if the vibration moves to the driver's seat.

I’m pretty sure there is supposed to be zero play in the drive shaft. It wouldn’t matter horizontal or vertical since the yoke can be facing a different direction each time.

I just meant it wasn’t forward/backward play.

There is tolerance between the splines of the slip yoke and output shaft; if it fit tightly it would wear as it slides inward/outward. Not something I’d be concerned with.

I’ve been hearing about K02 tires having issues on new Raptors due to QC at the BFGoodrich factory. Manifests itself with vibrations although your vibration’s speed range is pretty specific. Do the vibrations change if you adjust your pedals?
