Toyota Repair: 2002 Sienna Loose Front Lower Control Arms, rubber bush, operational condition

Question
Dear Ted,

I am a big fan of Toyota and their quality of service and parts.
My 2002 Sienna was done 90,000 mile check today.
I got one recommendation after the standard maintenance.
"Will Need Both Front Lower Control Arms, They Are Getting Loose (Parts $336.08, Labor$166.04)"

I would like to ask three questions:
(1) Normal operational condition can causes this replacement?  Is there any chance of defect parts? (There is no recall related this)

(2) Service desk lady told me that this is worn out parts and no immediate danger for driving next few months.  She said that I can change them in the next oil change.  Do you think this is not dangerous for a while?

(3) Do you recommend replace any related worn out parts during the replacement of both arms?  Such as rubber bush....

Thank you very much,


Answer
At 90,000 miles this is just wear and not a defect, there are no recalls on this.
It's not dangerous but there should be some noise associated with the worn bushings especially going over bumps.
The bushings come winstalled on the new lower control arms, you may want to take it somewhere else and get another opinion.
