I have a 99 nissan altima that i had taken to get an alignment done and the mechanic said im missing a rear lateral link and they could not do an alignment without it. I looked up under the rear and both sides look the same and does not appear to be missing nothing and i dont have a service book on the vehicle yet. Im just looking for a diagram of it so i can look at it and possibly do the work myself. Thanks in advance.

Here at NICO, we have Factory Service Manuals available free to members. Take a look at the link in my signature to find the FSM for your car. There's a dividing line at the bottom of all of my posts that has four sentences. The last sentence is the link to NICOclub's entire FSM database. When you click on the link it takes you to the main page that allows you to choose between the Nissan, Infiniti and Datsun FSM databases. When you click on the Nissan link a new page opens showing all of the Nissan vehicles that were currently have FSM's for.
