I had to use 4 wheel drive to get through the snowbank at the end of my street. I only use it in instances like this. I rarely use 4 wheel drive. When I shifted back to 2 wheel drive there is a grinding/whizzing sound from the front end. I got on the highway and accelerated to around 40-50mph there was a "thunk" sound then the noise went away and didn't return till I slowed down. Any ideas what it is?
