I'm new to Club Lexus and I have a problem. I think either my airbags or shocks are going out on my 07 GX. Would it be cheaper to replace what's wrong with OEM parts or just go ahead and get about a 2" lift? I would really like to have an excuse to lift it with a new suspension bit I'm gonna go with whatever is cheapest. It's sitting all the way down with no give when I bounce on the back bumper.

 

Forgot to mention... I get in and move a few feet and it fixes itself. No problem raising or lowering but have found it twice sitting all the way down with no play at all in the rear.
