Hi need a little direction where to start first. The front drivers side squeeks when the wheel is turned or when the car is bounced hard. I should add this is the SDL. I tried lubricating the bushings to no avail. Where to now? Anybody have any experience with this.

Sounds like the upper wiper seals on the shocks may be dry. Try squirting oil onto the shaft and see if it calms down. If it quiets the squeak then you may consider replacing the shocks at your next available opportunity. Do not use WD-40 or other thin kerosene based products on the shaft. They will work for the short term but will dry the seal out even more in the next few days. Motor oil, mineral oil, hydraulic jack oil, or power steering fluid would work better.
