I found this tds. It does not describe removal procedures but there is a graph of strength vs temp which shows a fairly constant decline as temp increases.
Iāve actually been wondering if the problem is the new hubs - that is, are the internal splines made to the same specs as the original. I donāt know how to measure that, nor do I still have an original around to compare it to.
The decline occurs in temps the hub would see in normal operation. I wonder if thatās what occurs with the blue thread locker which as I say is ok until everything heats up.
My left rear clicked before I did the new hubs and has clicked after the new hub installed with old spline
None of the other wheels do thisā¦
My understanding is that the loctite red is stronger which is why heat is needed to loosen it (not mechanical torque like for Loctite blue)
And there is a lot of torque on the spline/hub when you take foot off the gas or accelerate!

If you look at the tech sheet for Loctite 648 it says disassembly is with normal hand tools. Itās strength at heat is better than the ones being discussed - like the 660. Iāve used Loctite 609 which is a retaining compound on several things and itās incredible - actually I couldnāt get it apart even after the application of significant heat. 648 is recommended for slip fitted assemblies like the splines. Just an aside these fill voids to a depth of 9 thou. I suspect the spline fit is sloppier than that.
I think this might be the stuff to use: http://tds.henkel.com/tds5/Studio/ShowPDF/243%20NEW-EN?pid=648&format=MTR&subformat=REAC&language=EN&plant=WERCS
