Bank1 wastegate rattle??

From most threads I've read the common rattle seems to be coming from the second bank wastegate. I had that problem and fixed it following Mr.5's method. Now I think I have an issue with the bank 1 wastegate too ;( . I opened the splash shield tonight and managed to reach my arm up to touch the actuator rod and I can feel a little slack. I don't see any easy way of reaching there with a wrench to tighten it. Can anyone relate to this and are there any remedies besides updating the ECU or swapping turbos? I can hear it rattle between 2-3k rpm, pretty frustrating.

I appreciate any input.

Holy crap thank you! A bit labor intensive but seem to worth a try. So im curious does everyone bother to fix their front WGA if they're out of warranty?
