New to the Losi Night Crawler 2.0. I picked up a used one with the four wheel steering, and everything is wonderful. Except the rear axle (which is also a front axle with steering) gets VERY hot!!! Even the rear drive shaft gets hot! So I did my research, and lack of grease in the worm gear seems to be a common problem. Took it apart, greased it generously. But it still gets hot! I am thinking bad bearing? Or bad worm gear?

I have ordered the HD Worm Gear set, and a complete Losi Night Crawler bearing set (with two additional 6x12 bearings) from Jim's Bearings. While waiting for the parts to arrive, I thought I'd ask more experienced folks about what else can cause the axle overheating? Again, it is the rear axle WITH steering (so basically, a front axle).

Should I also change the worm gear in the front, if I upgrade the rear axle's worm gear? I read somewhere that installing the HD worm gear is basically equivalent to overdriving, and I don't want to overdrive the rear axle while keeping the front axle as-is. No good.

Thanks for any help/info you can share.
