Hi guys, got a problem some of you may have had. Ive framed off a 75 40 with a 6.2 sm465 sprung over with emu suspention. Got a full floater with lock rit locker. My problem is when i ran through all gears sitting on engine stands there is no vibration or knock, when i tighten rear brakes (maybe a little to tight) ther is a definate knock would this be one brake being to tight working against the locker their is a cordon joint in drive shaft and both axels turned 8 degrees
