I took my 1997 4runner sr5 V6 to get an alignment and they said It was so bad that I needed to replace all the parts in the front. I was wondering what exact parts I need to do this properly.

 

ITRs and OTRs to start

 

Get it up on jack-stands or a rack and spend some time pushing, pulling, and shaking your tires. See what moves. Might want a second opinion from another shop to see if they will tell you what is loose. I just had upper and lower control arm bushings cause alignment issues for me, but I've seen tie-rod ends (mentioned by hrt4me), ball joints, and steering rack cause issues. Good luck! May want to let the audience here know if you are running a lift of any sort, mileage, and what you have replaced for a more accurate reply.
