Nissan x-terra manual trans 2005

[cardestroyer]

Hi guys I am introducing myself as the cardestroyer from Australia. Me and a few friends have been trying to diagnose my work vehicle for 3 days without any joy and unfortunately the problem is preventing me from working. We cant afford a mechanic at this time. Gratitude would be an understatement for any help received. Here is what is happening. We thought it was a wheel bearing but after replacing the right front noise still there. We jacked up the front and wheels move freely with no noise. We did the back as well no noise but as soon as the load is on the car will move forward about one metre then held back. Feels like something will break if pushed further and tension felt. Same thing happens in 4wd and 2wd. Disabled ABS same thing. Thoroughly inspected underneath and no leaks and no sign of damage. It is as though the drive chain has something like when someone puts a stick into your bycycle wheel. Its cold over here and I have the flu I,ve given 110% but no solution kind regards to all, Rob.
