Hi Guys please help! my mk2 fiesta has developed a creaking when i take a sharp left and also can be replecated when i rock the car from side to side but not up and down??

Im on a tight budget (aint we all!) so i dont want to replace a ton of parts to get to the answer, the shockers seem fine so im thinking panrod bushes? or rear suspension arm/bushes. ive done alot of diy repairs but im not sure on all the correct names for parts so please forgive me.

Any help would be great and i know you guys are the ones to help as ive read this site for tips many times!
