I have a 92 bronco with a 302 and a manual shifting t case. I have had it about 6 months now but for the past 2 months I haven't driven it much at all. I recently discovered that the 4 wheel drive will not engage. I get a 4x4 light when I go into 4 hi, and when I go into 4 lo it is definitely in low but also definitely not in 4 wheel drive. I still have the original automatic hubs but am skeptical as to get new hubs just because they both failed to engage at the same time. I guess that is possible. Anyone have any other ideas?
