I am about at my wits end with this insistent clunking coming from the front end of my 96 tbird (4.6). I have replaced the rack and pinion, inner/outer tie rod ends, strut assemblies, UCA's and ball joints, LCA's and ball joints, camber bolts, pretty much all hardware, strut rod bushings, and calipers and rotors, and everything should be torqued down to spec. All were fairly mandatory since I live in Wisconsin, but the clunking continues. I finally swallowed my pride and took it into Ford, and they told me they were"almost definitely sure it might be the radius arm sleeve to sub frame being loose and needing spot welding"....verbatim. Problem is, I have never heard of or seen a reference to a "Radium arm sleeve". Through the power of the internet, I determined they may be talking about the strut rod sleeve. does this sound right? I feel as though spot welding it may not be my best option here, so if anyone has any insight into how the hell to make this noise stop, I would be indefinitely grateful. By the way, the clunking is the loudest on the passenger side, and can be faintly heard on the drivers side if i really slam on the brakes or take a right hand turn hard. The passenger side can be heard easily when taking a corner, or backing out of my drive way, then again once I pull forward. Never really at highway that I can tell.
