Hello
I am new to RC hobby. I recently purchased Grave Digger but out of the box I found some play in all four wheels. Front left wheel has little more play than other wheels. I dont know how to fix the play and maintain the vehicle. I tried searching the Internet but couldn't find anything helpful. Any links or help, please post in replies.
Thanks.

The Traxxas manuals are actually pretty decent when it comes to explaining basic maintenance for your truck. Traxxas also has exploded views of the truck on their website that come in handy when disassembling or reassembling your truck.

Play in a wheel can be caused by many different things. Without a better description of which way the play allows the wheel to move it would be really hard to diagnose over the net. It's also likely to be hard to describe.

Best advice I can give is to move the wheel with your hand and watch everything it's attached to and see what moves and what doesn't. You can't take the wheel off to get better acess and to see better if needed. Don't be afraid to take it apart, it's unlikely you'll break it. Plus between the manual and exploded views online you'll be able to get it back together.

Thanks for prompt reply. Actually u r right I am afraid to take the parts apart but now I will try. Are there any video tutorials for maintenance? Wheels in my car has play that allows them to swing little bit left and right. I think I need to do some toe in setting also on front right wheel because it doesn't seems to be at the same angle as left one, but even after looking at manual I got no clear picture of how to do it. Thanks for help.

I think need to do toe in setting also because the toe angle of both the wheels is not same but after looking at traxxas manual I couldn't get a clear picture of how to do it....proper steps are not given anywhere.....

Ok I think I know where the play is on your truck. For the Stampede it's normal to be able to turn/steer the wheels slightly to the left or right. There is what's called a servo saver that absorbs impacts to keep the servo from being damaged. The problem is servo mounted servo savers like the one on the Stampede tend to flex a little allowing the wheels to be steered a little. To verify this flip the truck over and you'll see the servo saver on top of the servo. You'll notice it has layers and if you try to move the wheels the layers won't move in unison and the middle layer may buldge slightly before the servo turns.

The steering tie rods run from the servo saver out to the knuckles the wheels attach to. These tie rods are adjustable and lengthening or shortening them adjusts the toe in or out. But before you start adjusting try adjusting the steering trim on the transmitter to center the wheels. If that doesn't work center the steering trim on the transmitter and adjust the tie rods.

There's lots of how to videos on YouTube. Everything from maintenance to upgrades. Most maintenance can be applied to any rc vehicle.

Thanks for reply Overdriven. I opened the wheel assembly of my 30th Anniversary Grave Digger and found out that there is a plastic hex screw part number 3654 which is not a tight fit with the assembly and due to this loose fit the wheel is having a horizontal play....I opened the assembly thinking to put some plastic rings that came as an accessory with the truck, but I was not able to take out the hex screw and put the plastic washers in between.
Do you know how to open the hex screws where the wheels are connected with the chassis?
