I have a 1997 Jeep Wrangler with a 4.0, Dana 44 front and rear axles and a Manual trans. Yesterday I was going to brake and there was a loud grinding and clunking noise coming from the rear end of the jeep. The jeep was also violently shaking. Since then the jeep has continued the same pattern but only as I brake. I've noticed a slight grinding noise when off the accelerator while driving but nothing as bad as when I brake. Anyone know where I should start looking for what might be wrong? I don't want to sit there and take the whole rear end apart. Thanks!
