So I have been loving my GP with brushless and lipo although when I drive it seems to be more crunchy/grindy than it should. I have the mod1 gears and they are a little louder than stock but it seems almost like the tranny or diffs or something. Is anyone else having this sound slash issue? Am I over-reacting? The Clod i recently built is so quiet compared to the GP...
Ahh yes.... it would seem that you have entered into the early stage of the grindy-grind-a-chunka-chunka-clunk-clunk.
In other words, it sounds like you need to order and install the hardened steel differential gears, like Brett mentioned.
I noticed this happening with one of my trucks awhile back, and I was driving it and it started making the grinding sound, next came the rear axle violently bucking.
The pinion gears in your axles are starting to go buh bye.
Just a heads up; pressing the pinion gear, onto the pinion shaft is going to be a little involved.
You have to open up the hole in the pinion gear a little to get the shaft in there, so you can have the gear on there and then put e-clip on the end of the shaft, locking the gear in place.
* One more thing ! * I found that using a thread tap drill bit that is a slight bit larger then the center hole in the pinion gear, is the easiest way to open that hole up a bit to press the gear on to the shaft. If you go at it with a normal drill bit, it will be a time consuming pain in the planetary !
Once you get that done, its just a matter of re-assembling everything. Put some grease on the pinion and diff ring gears, they come dry from the factory.
