Yeti Lynx 4S - 4wd to 2wd

[kissofthegypsy]

Hi everyone

I'm a noob and just wanted to check something, I have a yeti and just had a lynx 4s remote binded to it. I ran it for the first time yesterday and noticed that it was only running rear wheel drive, now my mate did tank it the day before and it did 3 somersaults and one of the back pins popped out but I didn't run it again so don't know if the tank impacted the 4WD or the remote binding.

Any idea how I check what the issue might be?

Thanks

your radio has nothing to do with why its only running rear wheel drive. i would suspect a grub screw backed out of one of the cups from the tranny to the front diff.

Thanks mate

I did a bit more digging, I can spin the front wheels and the drive shaft turns, but I can also, spin the front wheels in opposite directions?

thats because your front end has a open diff.

if the center drive shaft is turning then maybe something in the tranny went. get tearing down and keep the manual close. when taking stuff apart try to put the screws back in the holes they came out of that way when you go to put everything back together you will know what goes where.

I would check the screw on the drive cup on the transfer case.

Hi Fr8cture

Does this look normal?

No the through pin is gone which explains the issue. Common right out of the box. Nothing is holding the drive cup onto the shaft. Part # AXA0286
