Use the soft silicone hose so that you can snake it down through all those loopholes inside the case. The hard hose won’t work. Gets super easy each time I changed it.
My vehicle transfer case before the flush was pretty bad, like really bad. Felt like the the drivetrain was about to explode everytime I turn. Now its butter smooth.
Do you have a link to the hose. I have tried a variety of hoses but never felt like it was the right one for the TC job.

It is surprising how nasty that TC fluid gets.
