hi all! I have a '07 5 and i've got the front end knockety knockety over the bumps at slow speed. I have been pokin around for a while and have read the TSBs for this....I want to replace the swaybar bushings first, and if that does'nt cure it I will tackle the control arm bushings. What size is the stock sway bar in the front? anyone have a good source for parts? and if it seems like i have not searched enough let me know!!! thanks in advance!
