Ok guys next problem, the 4x4. In 4x4, the front right tire doesnt spin and makes a terrible clunking sound once you get over about half throttle under load. The left one seems fine. I flushed out the old fluid in the hubs and replaced it, it was a little low, but this didnt change anything. It has to be something it that hub making it not engage properly or slip. Any ideas?

 

Take the hub apart and check the parts out.Ther is something not right in it.If you let it go too long it will be a major repair.Sounds like the Hillard clutch may have went bad.
