    The bearing in you motor mount is destroyed. The second common thing is the bearing sits on a plastic piece on the slipper. If that bearing adapter melts you will eat spur gears.

    Also make sure that the spur/slipper assembly is inserted fully into the bearing. It is possible to bolt everything together with the assembly 1 to 1.5 mm proud of the motor mount.

    Good! I am happy you found the problem! Do you have a plastic or aluminum bearing adapter? If you don't have aluminum yet, I highly suggest getting one. Remember, we are here to help

    i use Hot Racing Steel spur gear and pinion. I have had this setup for about a month now and no problems so far. There are no signs of use on the the teeth. They are very durable, I have been driving in alot of dirt. Others usually say that the steel spur gear is going to strip your pinion, but I find the Hot Racing ones perfect. The spur gear is $15 and the pinion is $8. Its a great upgrade. I use it with my FLM aluminum center diff. Its bulletproof!

    I have an aluminum adapter, thanks for the great info. If there's any other things you might suggest I'm open to them.

    I've given this a lot of thought, but I hear a lot of negative reviews about it so I'm not to sure .. How much louder is it?

    I also run Hot Racing Hardened Steel spur/pinion combo. It's great and very reliable.
    I have 54/19 on my Slash 4x4 MT, and run in dusty/sandy terrains without any issues since the steel combo can eat/grind all the small sands that get into it.
    Unlike the plactic 50T spur on my stampede 4x4 (note that Hot Racing don't have steel spur smaller than 54T), if sand gets into it, it's very much chew up, and the next thing you need to do is to open the assembly and replace the spur, which is annoying and time comsumming.

    You can also go with the mod 1 spur/pinion combo, which is a little bit stronger, but only (not positive) comes with 5mm shaft.

    Most users don't want to use the steel ones since they said that the plactic spur is a weak point for breaking, but I find my time is far more valuable than that. Make sure you change the bearing at the shaft output periodicly.

    Great info hskb. I'll definitely look into all that.. I do have one more issue that I would like to resolve .. My truck seems to go in an out of 4wd. At times it's just running 2wd then goes back? Any suggestions I would appreciate very much!

    Make sure all of your wheel hex are good, also check the hex pins. Be sure to look at the splined parts that the driveshaft connects to. Those are the usual problems that stop the truck from having the 4wd work properly.

    Nice pics! I hope you know that spray paint may not last too long on the body. They have special paint for the bodies that stick better to the plastic. Looks good! I have yet to paint a body so I appreciate anyone who paints their own. Please keep us posted

    Do you have an update for us? Did you ever find out why your truck is going in and out of 4wd? What I listed are all of the reasons that I have ever lost 4wd in my trucks. One should be the reason.

    I haven't had the chance to go and check, I've been busy with work and school but this weekend should be good for me ! Hopefully I get all 4 wheels running at all times

    When you take the wheel off the hex should have sharp pronounced corners. Of they look rounded at all you need to replace them. To look at the pins, pry the hex off of the axle. The pins will be a shiny little bar that goes through the axle.
