I have a 1969FJ40 and I don't think my front end is getting any power. My guess is that it is a vaccum hose. Is there an easy test to see if the fron is getting power other than putting the whole vehicle up onto jack stands? I had someone watch my wheels while I was spinning on some snow, but we couldn't tell. Here's a question though: If I am in four-wheel drive, can just one of the rear wheels be spinning out? I thought for one of the rear wheels to be spinning out one of the front ones would also if you were in four wheel drive? Any care to explain some of this?
