Mentioning this for your information and education
Loctite is not “glue”.
Each Loctite product has a heat saturation point at which it will melt and release. That is so the parts held together with Loctite can be disassembled.
The Loctite 660 is made specifically to fix bearing races that are no longer a tight locked fit into their bores.
As such I would expect that it would survive in an automotive wheel bearing application. Typically I would expect the max temperature at a wheel bearing to be 200F If your wheel bearings are running in excess of 500 F so you begin to worry about the Loctite releasing, you will bigger problems than that.
Concerning the cost of Loctite, and you should know the answer to this, have you looked at the cost of precision machining lately?
Honestly I am a bit surprised that a person with your racing and machine shop experience is not already familiar with Loctite products.
