Revo diff hard to turn? - Chitown R/C - Chicago's Largest RC Car and Truck Community

I noticed on my revo today that the front diff is really hard to turn for some reason, the breaks aren't on and the rear diff is fine. But it seems like the front one is super hard to turn. Could it be low on oil or something? I'm going to take it into LH Wednesday if I can't figure what is wrong.

Take it in ???? You mean take it APART, don't you?

Maybe you broke it? Take it apart and find the broken stuff, lol.

lol, i can do just about anything on my trucks... Except the diffs, I dont want to tackle them until i see someone do them, i was just going to take it to LH so they can tell me whats wrong and i will do the rebuild or whatever needs to be done.

It's pretty straight forward kyle...No shimming or nothing involved.

I'm not sure whats wrong with it, I guess I can just take it in and they can tell me whats wrong and what I need to fix it, and I'll do it.

You could fix it yourself. Take it out, take it apart, and check it out

You'll be surprised how easy it is when your done.

BTW, with oil in the diff it should be harder to turn(so to speak) when spinning one wheel. The diff oil goes in the diff cup that bolts to the ring gear with four little screws. You need a light amount of heavy grease for your Pinion and ring gear when reassembling. Just a light coat so the grease coats the teeth.

OK, I'm not afraid to take it apart, I just don't know what I'm doing inside the diffs, it runs fine, but I can tell it is a little slower, and when I get off the gas it slows down like the brakes are on, I just came in from outside and when I turn the front wheel it doesn't even feel that smooth like the rear, I think it might just be leaking oil or something.

The truck came with a manual right???? Take it apart and follow the manual! Driving it is prolly just doing more damage to internal gears/diff cup... If it is already messed you will most likely have some parts to replace anyways now.

The only way to learn is to dive in and take it apart... JUST KEEP THING ORGANIZED... if you dont think you'll remember where screws came from get a piece of cardboard and push the screws into it... Then write on the cardboard where they came from. Take you time and have fun with it... Somtimes tinkering is just as much fun as racing... Knowing you built something so cool is very gratifying (sp?)

Yeah, I guess I will have to download the manual, I didn't get one.

I guess I will just start ripping it apart tomorrow.

Traxxas_Junkee · (#11 (**permalink**))

OK, I got it apart, there wasn't any oil in there, the screws came loose and it was all in the case, what oil should I have in the front, Im going to LH tomorrow after school to get some.

I told you over the phone like 50 times, 30k front, 10k rear.

Traxxas_Junkee · (#13 (**permalink**))

I know, but I was just going to say what other people suggested.

destroy_my_revo_15 · (#14 (**permalink**))
