Hey @FastEddy. I installed your bearing kit for the Nero and have two issues. It is missing servo saver bearings and there is now slop in the wheels hub. driveshaft can move in and out inside the hub. put the stock bearings back in and took the slop out.

Sorry for the delay but I needed to research this before getting back to you.

1) Yes, we did not include the servo saver bearings. It was not on the list of bearings needed we got direct from Arrma. They have now been added to the kit and the price has been adjusted to reflect the 2 additional bearings.

2) Slop in the shafts. Honestly don't have a clue and need help from you guys to figure it out. We do not have this rig in stock to test.
So far on our end we have checked the bearing sizes in the manual against what we have in the kit. Should be 8X16X5 and 12X18X4. We checked to make sure our bearings that are in the kit match these sizes in width and they do.

A) Can we get help measuring the ORIGINAL bearing width to make sure the Arrma published width is the same.
B) Will someone that got our kit please measure the bearings WE SENT to make sure the width is the same as the factory.

Thanks,
-Ed

Thank you, you guys are awesome. It is the inner hub bearing that is causing the problem.
12X18X4. the inner diameter is slightly off causing the shaft to be able to wiggle on the inside of the hub. I will mesure it precisely at work in the morning.

If you still have the ORIGINAL as well as the ones we sent a measurement on both will be helpful.

Sorry for the bad photos. the stock cannot be angled while on the shaft. your bearing can be tilted slightly while pushed all the way back.

Would you happen to have a caliper to take a few measurements of both bearings?

Stock I.D. - 11.9 mm

Fast Eddy I.D. - 12.00 (Right on the money)

Crazy how that small of a difference can get translated into so much movement in the wheels. All four corners measure out the same.

Any ideas fast eddy? More people from our arrma facebook group are also having the issue. Everyone who bought avid/boca are fine.

Has the wheel slop issue been addressed in the kit? I'm looking for a sealed upgrade soon, winter is coming!
