(IRS) Click Click Click and it Sea-saws under boost

[lukem80]

After the car has been driven for about an hour, when I return home or turn sharply (90 degree parking spots) I get the Click, Click, Click coming from the rear end.

I've been reading about this problem on here (http://www.svtperformance.com/forums/showthread.php?t=231653 ) and it seems like its one of the following:

1) CV axle going bad (most likely passenger side)
2) need my axles nuts tightened
3) Ford dealership says its 'normal'

I also have a problem (not often) of the car sorta 'sea-sawing/swaying' under WOT passed 3rd gear. if you don't let up.. it just gets worse. rocks back and forth and feels really wierd. never happened on the track just mostly on lang changes at WOT

I have an extended warranty till 08 or 60K miles... i'll take it in and tell them about this, but is their an actual TSB # on this? :kaboom:

I keep saying I'm getting a solid rear soon... this is BS

clickclickclick is a dying cv joint
poptink is usually rear antiroll bar end link loose
its been my experience that the loosey goosey rear is a loose axle nut. i found it amplified under braking though. also made its presence known when backing out of a parking spot.

i'd basically touch a wrench to everything on the irs subassembly.
