Refresh those Crawler Axles – CowRC Udder Butter

On my Axial Ram Power Wagon, I don’t hesitate when it comes to the water and mud. Between TTC’s, G6’s, trail running, and running in the sand, my bearings are starting to squeak their objections. Time for a tear down and clean up.

It’s easier to do this kind of job on the Axial SCX10 if you remove the axle from the truck first. Here is the front axle out of the Ram Power Wagon with the servo removed.

front axles removedWe start tearing down by removing the C Hubs and steering knuckles.

You can get individual bearings from them, or one of these bearing packs. In this package, they include all of the bearings you need for a full eddy bearings

While we have the cases apart, I’m going to put overdrive gears in the front axle. Doing this helps with climbing. It allows the front tires to work harder digging for traction, without the rear tires breaking loose as much.axial overdrive gears

This time the old gear in on the left, the new one is on the right. Interesting to point out, the old gear had little knobs to help hold it in place in the diff housing. The new gear doesn’t have those tabs, so all of the pressure will be on the screws.axle gear comparison

Here is the reassembled diff with the new axle gear mounted

These gate markers that come in the box when you buy the trucks make nice jack stands.set into caseHere is the jar of CowRC Udder Butter. It is long lasting waterproof grease. We’ll tear the cases apart in a couple months to show how the grease holds up to abuse.

Aside from keeping everything lubricated, it also helps stop dirt from getting through. udder butter beyind reason  Now we can put the case halves back together.cases back togetherFour bolts hold it together. The bottom two are nutted, the top two go into the upper link mount.cases back together 2

We’ll report back in a few months with another tear down to see how these hold up to the water, mud, sand, and whatever else we throw at them.
