What you're describing sounds exactly like Ujoint phasing, are both or all three depending on your set-up, of your sector shaft joints in the same "phase"?

According to many engineering discussions on the forum and from various steering part suppliers the joints should be 90 degrees out of phase.

You should contact Flaming River or Ididit for their feedback. There is also a very lengthy forum discussion on this that I remember reading about a year ago. Some very good information from Automotive Engineers. Just do a search on steering in the forum general area.

Also, I would not wrap the sector shaft and or ujoints with heat tape at all. I would be more concerned with the wrap degrading over time and jamming the ujoint while driving causing a very dangerous issue. If heat is the issue, you could make a heat shield to deflect heat from the header away from the sector shaft, but I would personally NEVER wrap heat reflective material on the steering shaft at all fearing a potential binding problem in the steering while driving.
