Big Rock First maintenance on my Big Rock

[SlooDon]

Loving my Big Rock. It’s my first “go fast” rig. My other trucks are trail trucks and comp rigs. I wanted to ease into bashing…….

I’ve run about 8 or 10 battery packs and figured I should go thru the truck. I found one bearing on the slipper assembly going bad and one axle hub screw coming loose. All else looked good.

I did let my jumping exceed my current skill level and pulled a rear shock apart.

From my research on the forum and YouTube I was able to correct/fix all my issues easily.

Thanks all for sharing your knowledge!

Great choice in rigs. My Big Rock is still my favorite all around basher. The shocks are the weakest link on them. I went with pro-line shocks but as others will say the 6s shocks are cheaper and you can get spare parts for them. As for bearings the stock ones on all the Arrmas suck. I like Jim's Bearings. Going over everything and making sure its properly fastened is always best. Pro-line Badlands unbelted tires make it much nicer and 30k front diff fluid with 20k rear works great for me also. Good luck and have fun.

Thanks. I’ll probably go with the Typhon 6S shocks eventually. I have a bearing kit coming also…….

I love my Big Rock, it was my first hobby grade RC 4 months ago! Now I have it and a Mojave EXB, they are completely different rigs and fun to drive for different reasons.
Welcome to the family and happy bashing!

Check all 3 motor wires and make sure they are all making solid contact.

I have Mojave from shocks in the front and kraton 6s front on the rear..I change the weight on them to 70W in the front and 80W in the rear with associate springs…

I love my big rock. Replace the Arrma bearings they are junk. Use blue Loctite.

I already had one on the slipper assembly go bad. It surprised me, only had 8 or so packs run thru it. I had spare 10x15x4 in my kit as it is a popular size in the crawling world. I changed both of them.

I ordered a replacement kit for the rest and will start changing them out during the next few maintenance cycles.

That’s a great shock combo. Got it on 4 cars. What size center brace is that? I forgot and need to get one…

May I ask, you are not using the Mojave or Kraton springs? But springs from AE? If so which ones? Sorry if I misunderstood.

Did you change the motor deg in the ESC. 15deg, 22deg, etc. also depends on what ESC you have
