Yes, chances are you need a new suspension. Many manufacturers recommend replacing shocks/struts/springs every 50,000 miles.
You can go with a Vogtland Sport Suspension but that lowers your car close to 2 inches.
KYB makes their Excel-G line for Avalons
Monroe makes both their Monro-Matic and Sensa-Trac for Avalons
Gabriel has a preassembled set for Avalons.
If you don't want it lowered you might want to go with KYB. They tend to be a bit stiffer (from what I've heard). Sensa-Trac and Monro-Matic tend to be more of an OEM feel with Sensa-trac having a better overall performance. I believe Gabriels are also an OEM feel.
It will cost anywhere from 500ish to 800ish dollars if you do it yourself and 700 or more if you have them done for you.
Poke around, do some research. Most manufacturer websites will have car searches that let you put in your car and they will give you your options.
