Netcruzer RC - JLB Racing Cheetah 4x4 RC Truck. After snapping the outdrive of the rear differential I took it apart and waited for parts from China. This is how to diff rebuild and repair the Cheetah or 21101 4x4 RC Stunt Truck. Want one? goo.gl/SznUh7 goo.gl/GsG2q4

Had the diff break on my cheetah and this video was perfect in every way for helping me figure out how to dismantle and put back together. Great vid 👍🏻👍🏻

[@cwatson42785]

Great video netcruzer! As somewhat of a newbie and a cheetah owner and someone who has never seen a diff opened this video helped me immensely! I really appreciate it and keep the maintenance/wrenching videos coming! They really helps out us newbs who like to see something before diving on in. Thumbs up and thanks again buddy!!

😂 squeezin the lube nice one it has happened especially with loc tite.

[@ItsRCTeng]

Nice...thanks for the diff built. I recently tried to rebuild the diff but all those small pins is such a hassle for me so I just replace the whole unit but thanks again for the build. I will definitely try to build when my diff give out again. 👍👍

[@richardcerni9996]

Nicely done...I have gone thru the same failure with my rear diff and you have shown exactly how to do it with clarity. Thank you so much. I must say, I don't find this car very durable, even though I like the model a lot. I don't know if you have gone thru this yet yourself, but because of the wheelie bar, and the way I have landed on it first sometimes from a jump, I found that it contributed to a slight inward bend on the rear shock tower causing my body lugs /holes to suddenly be misaligned. I have now solved this issue by inserting a threaded rod in the middle of the two shock towers. And just to show how much force is being exerted on the shock towers, I can tell you that I even managed to bend the threaded rod slightly, so the pressure upon landing from a jump was certainly there. Would have been worse without it I believe. It's a great little truck, I just wish it was stronger in certain areas.

Richard Cerni my neghbors has the same problem

[@potatojake197]

That moment when you squeeze the diff. fluid bottle to hard , R.I.P

[@netcruzer]

Yeah, whooops! Just a bit messy, and wasted 1/4 of the bottle!

[@potatojake197]

i thought that part was funny

[@potatojake197]

Do you think the Cheetah is worth almost $300 ?

[@netcruzer]

Value for money is decent, better than big brands. But driving dynamics are definitely worse. It's a fun truck because I don't care about it and am willing to bash it till it dies. For me that was worth the few hundred dollars, and it's fast.

[@potatojake197]

huh

[@BeachinRC603]

Hey I know this is mad old vid but did u ever have probs with the gears in the diffs spider gears I’m just ripping mine apart ring & pinion on the diffs are good just wondering

[@Dries_ngrs]

I can't get the pin out before getting the OP-DOG-BONE out! the pin is completely tight ... but my JLB cheetah is new I used WD-40 and it just wouldn't come off! how do i get that pin out? please help!

[@rapidshe1]

How often does this detail break down(a cup of differential)? I broke for 2 months 4 pieces: (

[@pedrogalvao7329]

Único defeito desse diferencial são esses parafusos, troquei e ficou mais eficaz para retirar quando preciso.

[@monkeytrident]

How is your Cheetah going, I just finally got round to repairing mine, darn bearings disintegrated :)

[@netcruzer]

Sold it many years ago. The diffs held up but the rear link design was too sloppy for me

[@darielsabay1391]

My cheetah when i disassemble the diff there is no washer shim on the four bevel gear inside....is it okay?

[@janchamizo5461]

I only have rear wheels power is the diff?

[@connylaurine745]

Is the diff box really seal enough that the oil doesn't leak?

[@netcruzer]

Yes, there is a waxy paper gasket too between the diff cup and ring gear.

[@connylaurine745]

@@netcruzer Thanks.

[@andrewap77]

I'm a newbie at this and I have a JBL Cheetah if I have to do that I will call YOU LOLOL or buy a new one.... Thanks for the schooling.

[@netcruzer]

+Tank 62 I think you can buy a prebuilt differential for this if you do need to repair or replace it someday.

[@A_Man_In_His_Van]

I'm no surprised it broke the way you drive.

[@netcruzer]

ryan olson I treat it like a stunt truck. And I abuse it as such. I’m not surprised either dude.

[@Mateo-jc9zg]

Does the cheetah have a slipper clutch?

[@netcruzer]

I’d have to say sort of. LOL. It has a spur with plates but I’ve never had it slip and I’ve not been able to loosen it. It’s effectively locked center.

[@rcimmortals437]

Netcruzer RC TECH CARS You can definitely loosen the slipper clutch to have it slip. I have done it to mine so it has a hard time even pulling a wheelie, I bash it and jump it so I need it to slip 😉

[@romeomenduni2310]

My frontdiff is broken and I had to exchange it. Now turn the wheels very hard and in the same direction. What did I do wrong? I put the New original diff in, without open it!? I think its ready to run? The wheels should be easy to rotate?

[@netcruzer]

+Basata 86 should be easy to rotate in all ways. Hold truck in air and two spin each wheels together and see if you can feel where it binds. Something's too tight or misaligned. Could you rotate the diff in your hand like I showed after rebuild?

[@romeomenduni2310]

Netcruzer RC TECH CARS Check my uploaded Video please. There you can see my problem. Thank you

[@romeomenduni2310]

So, I've now expanded everything again and even opened the diff. Oil is enough in it. The problem seems to me the Diff! The two axes can only be rotated with force against each other. In the built-in state, this solves a direct drive on the pinion ... I have now made the 4 screws of the differential somewhat loose so that the whole inner life slightly easier to move. But the Tires dont spin easy like the Rear :-( meaby i have to drive the Car and then its better..?

[@mafirstrc8930]

can i put a car gear oil? like sae 90 rating? hahah...
