Front control arm loose bushing

I am just installing what will be the 4th right front control arm on our 2006 Prius.. This will be the third time it has failed safety inspection because ot this. The reason is always that there is play in the front bushing. With the car jacked up you can see it move. The drivers side does not have this play.

I just removed the third control arm (Oem Toyota) and compared it to the brand new arm and the bolt is loose in both of them. I can remember thinking the bolt seemed loose in the bushing when I replaced the last one. The bolt was also new from Toyota. I am sure this is where's the noise and play is coming from.

So I must be missing something. I don't know if the bolt was not torqued enough. I was on pretty tight. Does anyone have the torque specs for the control arm? You can't use a torque wrench anyway because there is not room to get it in there.

Does anyone have any ideas?

 

The struts are about a year old. The strut mount is original, but the bearing had no sign of wear when I did the struts. The play is definitely the front control arm bushing. You can see it move
Yeah the right one is a bit of a pain but it's not that bad dropping the crossmember to get the bolt out

Thank you for the torque information. I actually just found that manual in another Prius chat thread. The recommended procedure in that is to actually remove the subframe from the car to change the control arms. That seems pretty crazy just to replace the control arms. One thing I did notice in that manual is that it says to torque the control arm bushing bolts with the control arm loaded. I'm gonna try this and see if it makes any difference, because as far as I can tell there is nothing wrong with the control arm.

 

Thank you for the help, I think I have it worked out. I did only drop the right side of the subframe to slip the front bolt past the oil pan.

Leaving the bushing bolts loose and then torquing them while loaded with the weight of the car seemed to make a big difference. The play and the rattling sound is totally gone. I did not replace the control arm because the old one had the same amount of play as the new one.

It probably is a good idea to replace the strut mounts when doing struts. In my case, I am quite sure the original strut mounts are not causing the problem. The bearings in them were in very good condition when I replaced the struts.
Also, I live in a rust belt so I am expecting the car will have rust issues, or will have battery failure long before the strut mount fails.
