4 Wheel Drive/SUVs: clicking noise 1995 chevrolet blazer 4wd, chevrolet blazer, hub

Question
There is a clicking noise behind right front tire. When i put it into 4wd the noise becomes very faint. No noises in reverse or park or speeds below 10mph. What could cause this problem?

Answer
Chris,

It sounsds like the right front hub is failing. The fact that you can put it in 4 wheel drive and the noise reduces tells me it is located inside the hub itself. I would try checking that hub to see if there is any wear or anything broken causing the issue
