    Slash 4x4 stock drive train ?

    I just got my cousins slash 2nd hand. I did some maintenance on it. In particular, new pinion, spur, bearing and aluminum adapter for center diff. This thing is all stock. The drivetrain sounds HORRIBLE!! It drives fine and the mesh is good. My question is..... Can the vilinian motor be makin noise as well as the fr/rear diffs? I know this is a general question, I'm just thinking of options before I tear into the diffs. Thanks for any info guys.

    In my experience, the Slash 4x4 is generally a loud truck. Its most likely not the diffs. What kind of noise does it make? Grinding, ticking?

    The stock truck has lots of chattering bits in the center drive train, as the center shaft, slipper/diff assembly, and front/rear differential ring-pinion has a lot of play. This is great for general use as it means impact flex wouldn't instantly gib anything, but it does make it really loud. If it stills drives perfectly fine I wouldn't worry too much about it.

    Thanks guys. Yea, it's not ticking, maybe more of a grinding if anything. Like I said, this one is 2nd hand. I'm used to my slash4x4. If anything I may take the diffs out and grease em up, ya know... The old once over. Do you guys have any advise on how or what products to use as far as diff maintenance?? Again, Thanx for the help!

    Check out Dollarhobbyz.com if your looking at buying new parts, especially if your need diffs or that kind of stuff. It's a RC Chop Shop, so they sell complete parts like diffs whole. And at pretty good prices.

    Before you tear into the differentials you may want to try a new spur gear. If it is worn it may make some noise. Also pull the wheels off and check of hair or other trash behind the hex. I use cheap automotive grease to lubricate the big gear on the differential. I don't believe you need to open the differential cups because of noise.

    The spur gear was the first thing I replaced. I also replaced the main bearing and upgraded the plastic adapter to aluminum. I'll try the cheep grease in my maintenance. Thanx man

    Move the motor and roll the car and see if the diffs are making noises or binding.
    The motor should spin free and smooth when you spin the pinion by hand.

    You could have a bunch of bad bearings at the wheels and diffs, so I'd tear it apart and inspect everything and clean it,
    .


    This was a used slash my brother bought.


    Cleaned and re assembled.

    And dollarhobbyz is a great place to get parts, I buy all my stock replacements from them as well as parts to build complete rollers for customers.




    I built these three trucks using a lot of parts from dollarhobbyz
