1991 Oldsmobile 98 suspension gong bad? How much am I looking at??

Shocks can be installed buy anyone as long as they are somewhat mechanically inclined. They are about $35 a piece. However, that model is front wheel drive and has McPherson Struts. They are considerably more expensive and require special tools to install properly. You car will also need an alignment too. There may also be other parts that need to be replaced. You need to take it to Pep Boys or Firestone or another mechanic you trust for a full estimate.
