change the sub frame.
ask your brakers yard for one

in UK i can get one for 50-60 pounds

support car place jack stands under sub frame. using an engine support to hold motor in place, disconnect anything that is attached to sub frame, ex: motor mounts. then unbolt sub frame bolts(4) and raise car to remove sub frame. note sub frame is heavy.

If your sure its stout It should be ok my? is what caused it has to be some thing louse or bent.

Typically these are replaced with a complete lower control arm. What happens is the ball joint is reseeding the lower control arm and rusts. When the old ones pressed out it distorts the opening in the lower control arm. When the new one is pressed in they never fit tight. Anew lower control arm is very easy to replace. 1. Jack up the vehicle on the sub frame or pinch weld. 2. Remove the pinch bolt that holds the ball joint to the knuckle. 3. Separate the ball joint from the knuckle. 4. Remove the two bolts that secure the horizontal bushing to the sub frame. 5. Remove the single bolt that secures the vertical bushing from the subframe. 6. Remove the lower control arm. If you have any questions I'll be happy to answer them.

REMOVAL & INSTALLATION The lower ball joint is integral to the lower control assembly and cannot be serviced individually. Any movement of the lower ball joint detected as a result of inspection requires replacement of the lower control arm assembly.

1. Raise and safely support the vehicle.
2. Remove the wheel and tire assembly.
3. Remove the nut and bolt securing the ball joint to the steering knuckle.
4. Remove the nut and bolt securing the control arm to the vehicle sub frame. To install:
   
5. Install the control arm assembly to the vehicle sub-frame using the nut and bolt. Tighten the nut to 69-86 ft. lbs. (93-117 Nm).
6. Install the lower ball joint into the steering knuckle and secure it with the nut and bolt. Tighten the nut to 32-43 ft. lbs. (43-59 Nm).
7. Install the wheel and tire assembly and lower the vehicle.
8. Road test the vehicle.

Removing the rack and pinion assembly from a 2002 Pontiac Grand Am Se To get the old rack and pinion off of the car for replacement involves lowering the sub-frame, removing the stabilizer bar, and pulling the rack out from the driver side of the vehicle.

• Start by lifting or jacking up the car and removing the front wheels. Once the car is safely supported, disconnect both tie rods from the steering knuckles.
• The rear motor mount sits on top of the cross-member part of the sub-frame, and must be disconnected to allow the sub-frame to drop a few inches. Remove the three bolts attaching it to the center of the sub-frame - one in the back and two in the front near the back of the transmission.
• Loosen the two bolts holding the front of the sub-frame. Place a scissor jack or bottle jack under the rear of the sub-frame where the bolt for the motor mount was. Remove the two smaller bolts from each side of the rear of the sub-frame (total 4 bolts) and then loosen the two remaining larger bolts holding the rear of the sub-frame (these bolts go through the rear control arm bushings and are very long) until the bolts are only going through the control arm bushing, and not into the chassis. You do not need to remove these completely.
• Remove the stabilizer links from both sides.
• Next you must disconnect the steering linkage. This is done easily by lifting up the rubber boot to expose the small bolt holding the linkage. Remove the bolt and pry the linkage upward using a pry tool or screw driver.
• Near the passenger side of the crossmember, remove the bolt holding the power steering line bracket to the chassis. You may now begin to lower the sub-frame using the jack. The front bolts should have lowered the sub-frame about a half-inch or so, allowing you to lower the back of the sub-frame 3 or 4 inches.
• With the sub-frame lowered, you can now access the bolts holding the stabilizer bar in place. The right side has a nut screwed onto the top of it holding the power steering lines, remove this first, then remove both bolts. Pry or pull the stabilizer brackets up and out. Remove the stabilizer bar.
• Now you can get to both of the bolts holding the rack in place. Remove both of these, then begin to slide the rack toward the driver side wheel well until there is no more slack in the power steering lines. At this point you should be able to get to the nuts securing the lines on the rack. Loosen both nuts and be ready with something to cap the ends with. I used part of a plastic bag and a wire to tie it. You can now pull the rack out through the driver side.
• Be sure to replace the rubber o-rings on the ends of the lines when putting the new rack in. Replace everything in the reverse order. Put your tie rods on the new rack, making sure to count the turns or make a mark or measure to be sure your tie rods end up close to the same length as before.
• Bleed the power steering system.

Important: Get an alignment! Not only is it dangerous to drive with your steering out of align but it will also grate the tread off your tires in a matter of weeks or even days.

either a bad sway bar end link noisy,or the lower control arm busgin is collapsed,if it slight noise its the sway bar link if its a loud metal to metal slap is the lower control arm bushing,,,check to see if its laying against the sub frame,it inline with the back of the front wheel and there is one 21mm bolt that goes thru it from the bottom,thats the are its at , common issue

replace the sub frame this job is very difficult if you dont have proper tools to do the job if you want details let me know

please give good rating if this helps
