Be sure to change the rear axle fluid at 15K per the manual if towing heavy. I mistook the 24km for miles, oops!
At about 20K+ on take off turning I would get a bit of a grabbing feeling when towing. Made it home from our long trip and changed the lube at 24K and sent an oil analysis with Blackstone. The two Viscosity tests showed the lube was below the minimum.
Did the fluid change take away that grabbing feeling? I noticed it on our summer vacation while starting from a stop while towing too.
