On the axle nut there is a flange that you need to indent with a hammer and
chisel to keep the axle nut secure. Did you do that. A properly secured
axle nut will not jump the theads..
And, if it's the style that uses the indented flange nut, that nut
should be replaced each time one takes it off for best results (yeah, I
know, a lot of people skimp and don't do it!) My '90 Loyale uses a
castellated nut with cotter pin (the pin should be replaced each time,
too) so I don't know what style's on the '92.
Another possibility is the actual threads on the stub axle were damaged
(partially stripped, rusted, worn cuz someone DIDN'T torque the nut
properly at one time?) which makes it impossible for the nut to hold
torque. And a torque wrench isn't THAT expensive compared to damaged
parts, and safety problems, from inadequate torque. 147 ft/lbs, which is
the minimum my book calls for, is a pretty fair amount of torque,
applied easily only with a goodly sized breaker bar or torque wrench. I
seriously doubt I could come close with a regular sized ratchet or
wrench.
Sounds to me like a rather minor problem to diagnose and cure, worth
investigating, rather than getting rid of the car.
