I'm really interested to see how that motor mount cross piece mounts... as there aren't any extra screw holes in the chassis plate, yet you can see the thread in the cross piece and mounts... Wonder if it's a counter sunk screw in the mount, then onto the chassis.

Its gotta be. North/South mount a lot easier to deal with too

Hi guys,

I hope some of you experts can help me a bit with my 417.

When applying 50+% steering, I get some weird grinding noices and a lot of vibrations. It is not the normal spool wheel chatter, but it is a lot more violent. The problem is also present with a geardiff.

I have changed steering knuckles, C-hubs, wheel hexes, wheel axles (51445), and probably more that I've forgotten. The problem is, as far as I can see, in the front, as I have tried removing the belt and turning the wheels by hand, without improvement. I have tried removing the dampers, and detaching the steering and the camber links. No improvements.

I recorded it, so you can see it yourself:
+ YouTube Video
ERROR: If you can see this, then YouTube is down or you don't have Flash installed.


I hope someone knows about the problem, or can see it from the video. I have had 3 different Tamiya-drivers looking at my car, and no-one can find the problem.

Have you tried replacing your front axle, cross joint, and swing shaft assembly and replacing the plastic spool cups? It is clearly binding up at sharper angles causing the wheels to hop and vibrate. Over time these parts start to dry out and bind-up more often. I check and relube the front drive train about once a week to ensure smooth operation. Last time I had an issue like this it was the spool cups. Replacing them fixed the problem.

Car sounds smooth when going straight so I would assume that nothing is stuck in the teeth of the pullies.

That was my first though, but that is not the case.

I have tried with a completely different (but older, so that might have the same problem) driveshaft. I will try with two driveshafts I know work tomorrow. I don't think it is the spool cups, as I also have the problem with a geardiff.

Perhaps a silly question from my side.....But perhaps the drive shafts are to long?
Then when turning they push against de rear of the spoolcup and that causes the vibrations?

That's normal chatter off load, always will have vibration at more extreme steering angles due the nature of the spool and standard CVD shafts.

Most touring cars have it, unless they are running double joint driveshafts.

+1 Spot on. Chatter is amplified when the car/tires sits in the air.

A picture with your post, when trouble shooting, will probably get more rctech help than without...

44mm - like the stock driveshafts. Just steel.

The problem (the noise at least - can't see about the chatter) exists on the track also. It sounds very violently, and none of the other 417's sounds like that. The problem just started from one battery to another. And it didn't push the throttle on that video - it gets a lot worse when applying more throttle.

Lower your epa on your transmitter and see if it still happens

I'm gonna sell mine and revive the 416WE with the LiPo chassis. And then only for high bite.
