Gear Probs...!!
 

Ok...i have searched the threads for a possible fix to my problem....no luck. So here it is:
I have this grinding noise and gear slipping when i run my car. If i try to drift there is a weird noise that sounds like clattering but much faster. I dont know what is causing this so please help:)

every once in a while i have the same problem. i take the rear end out and clean everything. especially check if the driveshaft is in the spur gear correctly. take the screwdriver and clean the differential. if you have bearings or AWD make sure to clean all of that too.

Check the gears and see if there is anything wedged in them. See if they are properly installed, and try greasing them with a lubricant. I will see if I can find the correct one.

Chuckster...

Thx guys...ima try that stuff tonite. I cleaned my diff b4 when i had a loud screeching noise and cleaning it stopped the noise. Maybe if i clean it some more it might stop the prob.:)

Glad to help!

AHH! no use...:o
well i cleaned everything that the gears connect to...lubed it with litho-sumthing grease...changed the motor. its still the same! there is still this grinding/skipping noise coming from the gears. Plz help if anyone knows the exact problem...

just in case nobody knows what im talking about...i attached a recording of the noise that my car makes when i rev it in my hand. Before i switched the motor, it didnt have that screeching noise, it had a weird grinding noise instead. When i run the car on the ground, the screeching disappears but then the grinding noise comes back.....Click here to listen (you may have to right-click and save target as)

I just found out the only the drift motor makes that screeching noise. The drag motor makes the grinding noise, the road race makes an even louder grinding (and is very very slow now...the gears slip) and the top speed barely even moves (but you can hear the gears slipping) I know its not the motor because i have checked. Its something with the gears or the diff

ok...Today i just figured out that the diff and the spurr gear dont get enough contact. Is there any way to fix this? anyone?

:oCan someone please help?! i want to run my xmod...im bored:(

MMM...You know those two screws that attach the back end to the middle chassis piece? Try taking those out and putting them in again, make sure that it goes in all the way and not crooked. I've had that problem before. Yours might be different.

Theyre not in crooked...they're straight. They go all the way in.

Out of ideas... But maybe you could take a few pics of different angles?

Pics of...? the gears?

yes the gears. did you check if the rear driveshaft holder was broke? try reseating that. you have to remove the motor, take the screws out and put them back in and put the motor back in. that might help. did you check the pinion? see if something is in it.

Yes! its the driveshaft holder...does anyone know the part number cuz i dont know which one in the FAQ. :D Thx for the help

at your request here they are:

12414231 - HOLDER CENTER SHAFT (FRONT) $2.49
12414249 - HOLDER CENTER SHAFT (REAR) $2.49

well, that sound is too familiar to me. btw, nice audio equipment for the recording. what kind is it? but back to the topic at hand. make sure that the back end of the car is connected to the correct holes in the bottom. with my rsx, i heard that sound because i made the chassis too long so the driveshaft wouldn't quite fully fit into the diff gear. this caused it to slip on the gears sometimes, which is what that sound is to me. the screeching sound? i have no idea what that it. but i think i just spotted that grinding noise.

I used a mic that came with my PC and SB16 wave studio

Anyways, i temporarily fixed the problem by using rubber cement on the shaft holder. I know it wont last long but its worth it for one day's run :D

BTW: I also need the name or part number of the black part where the wheel goes into. It seems the bottom of mine got grinded down and caused my suspension travel to become smaller, which made my turning radius to the left ALOT smaller and ALOT bigger to the right(Turns out suspension does matter in these little things :eek: ). I lost the screws for this and i am also wondering what the hardware kit has....the screws and such?
Thx for all the help...i greatly appreciate it :)

what black part?
the hardware kits are backordered. when they come in im gonna order one out of curosity.

The part that the wheel goes into (not the metal piece). It holds the suspension arms in the front and the tierod.

check the FAQ if you want just that but the AWD kit has it too

hmmmmmm
 

i had that problem with my skyline before I returned it, I dont know if this was already covered or what but my problem was a piece was actually missing off of the ball diff. it looked like it had just snapped off.

hope im not repeating what someone has already said....

I had a problem similar to this but mine seemed dif but ill post my fix so you can check it anyway

(this is only if you don't have AWD installed)
Take off the cover over the front and make sure that the black piece that holds the drive shaft in the right place is in correctly. mine got flipped upside down when I was working on my car and I didn't notice so it slid past that thin black thingy and popped out of the gear in the back. To tell if it is in right or not, check this. If it is in wrong, the only thing touching the drive shaft will be a thin black peice of plastic touching the end. If it is in correctly, the part touching the end of the drive shaft will be like an L shape. One part of the L holds the drive shaft from sliding further down and the other part extends down past the side of the drive shaft to hold the bushing/bearing in place. (it's likely that it got flipped after you did the bearings upgrade, if you did it)

hope this helps
