I have a 2004 Grand Prix GTP and randomly one night while getting gas the left linkage on the rear sway bar broke and the left side of the car dropped a bit, well my brother in law welded it back together and it only lasted about a week and broke again, then a couple weeks later the right linkage broke which made the car lower in the back, is this an absolute necessity to have because I've literally drove the car probably 2 months like this and I haven't really noticed a difference other than it DOES seem like it throws you around a bit when you turn the steering wheel if you're on the interstate like it kind of bounces side to side, is this the only issue this will cause? If there's a better way to fix it than welding it back where it broke I can do that just let me know, I haven't priced the linkages I actually don't even remember if they're made to the sway bar or not honestly it's been awhile now.
