Was there some kind of accident that bent the Bundy tube? If you can take the whole rack cable out you can then check whether the wiper spindles move freely after removing the wiper arms. Tip: feed the wiper rack into a bin bag so you don’t get grease everywhere. You also do not want dirt to stick to the grease because that makes an abrasive paste. That first section of tube that goes from wiper motor to the passenger side wheel box can give the impression that the rack is binding inside if it is not orientated correctly when you are feeding in the rack.
What I am saying is, I cannot see how that section of tube could be the problem unless I got crushed or bent out of shape. It is more likely that the passenger side wheel box is very stiff or seized altogether.
If, after checking that the passenger side wheel box is not seized, you want investigate further then you will need to take out the passenger side glovebox to gain access to that wheel box and the Bundy tube.
The Bundy tubes are clamped in position onto the wiper wheel boxes. To remove the tube you need to remove that back plate from the wheel box but be aware that when you do this the middle tube (that goes between the wheel boxes) will also come adrift. When refitting the Bundy tubes you must be careful that they are properly positioned before tightening up the nuts on the back plates or the tube can be crushed.....
