Mine kept doing the same, so I just pulled the shields off and oiled the bearings with a good bearing oil (muchmore spin lube) and they have been fine.
Cheers

Yes, sorry I forgot as the 2011 car use's a different bulkhead compared to the 2010 car which used a larger bearing (13x10x4 I think compared to a 8x16x5 on the 2011) which had a built in plastic dirt cover. The other thing to try is use kyosho or Hpi metal shielded bearings.

Never had that issue with mine. If it's popping out, something is distorting the bearing allowing that to happen. Or the quality of the bearings you are using is questionable.
Ensure that the pinion gear is tight and has no movement in the bearings. You don't want it to slide back and fourth at all.
I've run the stock Xray bearings and Avids, never had a seal pop out.

Avid revolutions. Put the seal facing out. As others have said, make sure the pinion gear does move in or out. You should be able to run the avids for gallons of worry free running unless you are in extremely dirty or muddy conditions.

okay i just double checked and YES, the pinion gear is moving in and out which is probably why the bearing seal is coming out.

How do i make sure the pinion is seated tightly, i look thru the manual and it shows that you need to screw down those screws to hold the bearing down in place in the bulkhead.

But on the 2011 spec you do not have those screws to hold down the bearing in the bulkhead.

Please assist.

What I did mine was put a shim in between the two bearings so your pinion won't move at all.

As mentioned before, Never had problem, just make sure there is no back and forth pinion play. Use Avids and have not had that issue.

Pull your diff out and loosen the set screw on the coupler for the drive shaft. Put your finger on the pinion and push it into the bearings to make sure everything is seated, keep pressure on it and slide the driveshaft back on the other side. Push the coupler from the driveshaft as tight as you can against the outer bearing and tighten the set screw. This will get it nice and tight.
The 2011 doesn't use the 3 screws on the inner bearings, don't worry about that.
Now put your diff back in and check the mesh, you may need to shim the pinion to get it right.
With it loose the way you have it, it's constantly floating in there and will cause premature wear on the gears. It also leaves the potential to bind under heavy chassis flex which can break expensive parts.
