Lowered Suspension Help

[edroders]

Hey guys as i hope you can see from the pic I'm having an issue with the rear suspension (both sides) in my Au Fairmont Ghia. it has SL King Springs and lowered Monroe shocks all round ( Less that 2 months old). i realized there was a problem when trying to accelerate the car felt like the rear end was swerving quite violently. Any suggestion as to how to rectify this would be greatly appreciated...

Thanks Roders.
