1 Wheel not turning?

Hey,

I have a HPI Trophy Truggy Flux and the front left wheel is acting weird.
Since this is a 4wd system whenever I rotate a wheel, all others rotate. This works fine for the other 3 wheels but when I rotate the front left wheel, nothing else turns. However when I rotate another wheel the front left wheel DOES turn.

I thought this was odd when I noticed it so I held up the truggy and accelerated. The problem wheel was clearly rotating at a slower rate.

What could be the cause of this? and How can I fix it?

Thanks!

Sounds like your diff is either loose or has a broken spider gear. I had a similar problem with my savage recently, it turned out that the three little screws holding the diff case together had come loose, so it was allowing the spider gears to slip. Pull the diff and have a good look, if it's not loose open it up and try to find something that's broken or out of place.
