Replaced both hubs, all tie rods, steering box, all suspension bushings, brake calibers rotors and pads, upper ball joints (lower ones are still good), diff gears and fluid are all good, axle shafts and splines are good, pretty much everything that has to do with the front end was replaced. Some parts were bad, some was just a proses of elimination. Still knocks on turns and NOW knocks when driving straight, too. You can hear and feel it on the floor. I'm taking a vacation soon and have been trying to get this knocking fixed but can't seem to fix it. Please help. Thanks.

 

Is the exhaust system secure? Ever since i tore my muffler my cats been banging around.

 

Did you ever get to the bottom of your issue? I just had my front diff apart to replace my axle oil seals and now that I've got everything back together there is a distinctive knocking sound when I turn and a loud squeak whenever the vehicle is in motion. I've narrowed the squeak to be coming from the front drive shaft by the transfer case. The knock seems to be coming from the passenger side of the front axle, but I don't think it would be the u-joints since those are relatively new (unless I got a defective one). I was pretty careful when I took my carrier out, but I'm wondering if I may have accidentally switched the bearing caps and now I've possibly got some excessive vibration due to stretching of the caps.
