You can see how the splines become sharp. Like little triangles. In reality they are more like Pyramids ![](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/1X/fa3f9cfb963c7c4d0cc7912e6edd1abb99a184c5.JPG) ---

Check out the splines close to the bearing (left side) They are untouched. Look at how the motor has wore them into a completely different shape. ![](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/1X/24679f91dea7762ae606168027455abd54dc7da1.JPG) ---

Grant; thank you so much for the valuable information. I will tear into the project this week and get back to you with my findings. It does make sense to do the upgrade. I will speak to previous owner to see if he knows what transmission work has been done. I have a copy of a work order from electric car in Palm Springs listing transmission service $485 parts and labor but no description of what was done. I will also call this shop to see if they can provide any further information Mike ---

Owner said electric car distributors replaced the Q-charger in 2009. He brought it in because it would barely move and he thought it was a transmission problem. They diagnosed it as a charger failure. What is your price for the replacement shaft including all necessary parts. I would need everything shipped to me in California. Thanks. Mike ---

Here is what a nice new Input shaft and OIL seal look like. Notice how GEM switched to a open Berring on the new one and they use the black oil seal to hold back the oil now. ![](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/1X/28a165bb91b912e112fd7721aad6c5f57913b106.JPG) ![](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/1X/030015cb0a1d037dac1787a48fcab06d70d492a3.JPG) ![](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/1X/eb464dd849c0d00b0067cd1e3f4adb33b27a8576.JPG) ---

I am not sure of the gearing as I just purchased it from a fellow GEM owner. My input motor gear was badly worn and made noise on deceleration. Best person to ask would be Grant West. He knows a lot about the GEM transmission set up. ---

This looks like the one I just got from NEV Access for $10 but can’t be sure of the diameter. I didn’t get it because from what I saw on other sights, it looks like it was flat on both sides but those sites were only showing the flat side(WTH?). And the one I got from NEV Access had the same coarse teeth while the splined socket had far more and smaller teeth.

Greetings all… I am reading up on this vibration issue and it led me here. Great info in these posts. Where can I obtain some of these rubber bumpers? ---

I just bought one from buggies unlimited. They seem to be the cheapest place, they have $5 shipping sale until the 15th I believe. That’s the thing that kills me, a $2 part the size of a coin and everyone wants to charge $12 shipping. ---

Note that they have 2 different kinds. I’m not sure what kind is better. I didn’t notice there was 2 different kinds and only bought 1 so hopefully I got the right one. ---
