    So today when I got to work, I went to back into a spot and noticed a weird rattling/clunking noise. The noise continued as long as I stayed in reverse. In drive, it disappeared. No noise in park or neutral either. Fast forward to my break 4 hours later, noise totally disappeared. Good enough...

    I have a 2008 2500 Cummins and when I'm in 4 hi and 4 low my front end pops. It only pops when I give it some throttle and it has to pull hard. The popping has a slight ring to it and sounds like its coming from the left front. I have tried to look this up but I am not seeing anything that...
