[urq] Rattle at higher rpm

[Todd Phenneger]

Oh,
If only you guys could hear my 4ktq.  The roads here in Belize are Killing
it.  I've already thinking it needs a 1/2 Cage just to stiffen up the
Chassis.  Its like driving Rally Roads to work every day.

FUN Though.  But last night while going out in Chetumal "southern Mexico" on
some real roads, I had at least TWO (2) new squeaks to find.
Seems I have blown my Passenger side upper Strut Bearing in under $3,000
miles.  
Seems I have a speed related squeak that goes away when I stop.  Center
Driveshaft bearing maybe?
My Delrin Bushings are Squeaking.
My Passener Side window squeaks horribly when rolling it up.

Fun fun
