K, I have a 2010 Kona Blue GT Premium w/trac pac, 5-speed, I lowered it with an eibach prokit, used Tokico HP struts & shocks, new GT500 strut mounts, as well as BMR boxed lca's, non-adj uca, w/ relocation brackets, BMR single adj panhard bar w/ new panhard brace, I put Boss 338 20" wheels w/255-35-20,285-30-20 tires on them, now when i had it aligned all was well except for the dreaded swaybar endlink bump, new adj on the way for that, but problem is this, I drove the car roughly 250-325 miles with no abnormal sounds other than links, and now I have a whine which appears to come from rearend at highway speeds when warmed up, I need some input to what you guys may think it could be, pinion angle? Pinion bearing? Carrier bearings? I am totally lost, and Ford will not touch it. Thanks

If you didn't put in a one-piece driveshaft it shouldn't be the pinion angle, as the two-piece allows a fair amount of leeway, but you might want to get an angle measurer and check for sure, as whining from the rear is often the diff.

Thanks, What was strange is how it started after a road trip I made down to Mobile, Al. hoping its not to bad.

Alabama will have that effect...

Yeah it will...... Hwy 45 is rough as he** too. Now im thinking internal bearing problem, because no vibration or grinding, just an aggrivating whine above 55-60 when warm.
