I have a 1997 80 series Landcruiser, the vehicle drive fine in reverse; but when it comes to drive it stops and goes.... I noticed the jerking up front, pulled off the front drive shaft --- isolated the problem to the front differential gears... (I had the rear axles and "pumkin", not a difficult project... but time consuming)....my question is how tough is the front to pull apart.... any special tools required.... It appears to be a little more complicated than the rear.... but I don't think its worth the labor the pro's are charging. Thanks in advance
