need help trouble shooting my savage x 4.6
 

So, I've had my truck since November and have only been able to use it about 6 times. I broke it in properly and have only used about 1/3 gal of nitro. Right after I broke it in the throttle servo went out. I replaced that and about 45 minutes into running it in dirt on a flat surface I noticed I was losing power. A couple minutes later I knew something was wrong. I picked it up, hit the throttle a little bit, and saw that only the front two wheels are turning. Anyone encountered this or know what I should do? This is my first nitro "rtr" so I don't even know where to start. Any help would be appreciated. The truck is almost brand new and I'm hoping these two issues are not the beginning of list :confused:. I haven't even jumped the thing yet, let alone raced it hard. :o Thanks in advance.

Is the rear dogbone (driveline) turning? Have you checked your rear diff?

The rear center driveshaft sits in what's called outdrives. One is on the transmission and the other is on the rear end. It bolts to the pinion gear. Check both of these and make sure the bolts are there and tight. I believe the bolt is a pin type which goes through the shaft. If this bolt comes out of either one of the outdrives, it will either spin on the tranny shaft or the pinion shaft.
Very good chance this is your problem.

You are correct. It was the bolt in the rear. Now, Im not sure what bolt goes in its place? There was a back of spare bolts and pins but I dont know if one of those is the replacement or if I need to purchase it separately. Thanks for the info!!!!!!:D
