I have got Profiles on my ride, and they start to creek when some dirt gets in between the arms, cone spacers, and bearings. Just take them apart and clean them with a rag. be sure that when you put the arms back on the spindle that you put some grease on the splines. That will prevent the arms from seizing on the spindle. Oh yeah, WD-40 is the devil. That crap shouldn't even be mentioned in any of these threads. For wet lube, go find some Pro Link.
