Transmission? Need Help!

[pinkducky]

I was out tuning and running my Savage and about an hour into it. My back wheels stop working. Is this a transmission issue? Sorry I am new to this! What do I need and are there any tutorials on how to fix this issue. Thanks for the help guys!

check the screw that joins the rear drive shaft cup to the diff. its the "grub screw".

 

[Combuster]

check the grub screws that hold the out drives for the drive line because they have a tendency to fall out. and check for broken dogbones because it is usually not a tranny issue.

The dog bone is fine. Sorry for asking this newbie question, where is the "grub screw" located? will I see it by flipping the truck over? Is it suppose to hold the rear drive shaft cup?

 

[Combuster]

yeah it hold the cups in place

In that hole the scalpel points to is a screw. that is a grub screw and on every cup there is one. don't forget there is one under the brake disks too

WOW I'm missing a steering post screw thanks for making me take the pic! its a freebie now..

Yessir. You can buy them online from the links below. Your LHS may supply them too. Give them a call. Make sure you tell them it's called a "Screw shaft", based on what HPI calls it on the packaging. Be sure to get the right size one. They have them in M4 and M5.

They look like this.
