I have a 300 4x4. There is a grinding sound when engine breaking down hills. On the flat or under acceleration it docent make the noise! So me and Tex threw it up on a lift in search of the noise. We have come down to the rear u joint is the posable source. We had it running in gear on the stand with the suspension fully relaxed, thats when we can hear the noise. We used a ratchet strap to load up the rear suspension and the noise goes away. Has anyone come across this? Is it because the angle is so great is why the noise is made? Is the u joint on the way out? Looking for some help
