Wheel hop is a condition where your tires don't quite slip and spin but the don't quite hook up either.. what happens is your tires start to spin but they catch a bit of traction.. when this happens it causes your tires to bounce.. Your tires will keep bouncing untill you either get full traction or they just start spining.. It's quite niosey and hard on the suspention..
Ya.. also on my cavy i have thumping noises when i hit bumps in the back. Its not regular noises that i should hear... it sounds bad. I hit a bump and thud. thud. thud. Sounds like the back strut is bad.. anyone know what is causing this?
