2009 Chevrolet Cobalt Control Arm Bushing Parts and Q&A

• Q: How to replace the control arm bushing in the rear suspension on 2009 Chevrolet Cobalt?

  A: Repairs to the Control Arm Bushing require lifting and supporting the vehicle before removing its rear wheels. Two screw-type jack stands should be placed under both rear axle ends before removing the body's rear brake hose bracket attaching nuts that allow free-hanging brake hose brackets. Start by removing lower shock bolts so you don't damage brake pipes while lowering the axle using hydraulic jacks before letting the Coil Springs free themselves. Fasten the lower shock bolts temporarily while the axle gets its support then remove the bushing bracket to body bolts at both rear axle ends. After using jack stands to elevate the axle rear section, move the bushing bracket pivots out of the body frame and unscrew through bolts with bushing brackets before marking down the old bushing dimensions. Use the j 44570 with the j 44570-1 positioned between axle sleeve and bushing flange; a light hammer may be required to completely seat the tool. Install the j 44570-3 through the j 44570-1 and the axle bushing before adding a hand-installed washer and nut that should be tightened to a slight tension. After hammering the bushing out of the axle sleeve users must disassemble the tool before removing the bushing. When installing new bushings into the axle sleeve maintain their removal orientation by positioning the rubber end inward while positioning the largest void toward the wheel hub center. Start by placing the j 44570-1 on the bushing before installing the j 44570-3 through the j 44570-1 and the axle bushing as you position the j 44570-2 bearing washer and nut. Pull in the bushing into the axle sleeve while holding the hex end and turning the nut before disassembling and removing the installation tool. Set the alignment slot of the axle brackets on the outboard side and direct their through bolts toward the inside before installation onto axle bushings. Lower the rear of the axle until the bushing brackets touch the body then install all bolts, park brake cable brackets and nuts while keeping them loosely fastened. The axel bracket to body bolts should be hand-tightened only to hold brackets flat against the body surface until axel through bolts receive correct trim height adjustments before final torquing of bracket to body bolts. Apply the specified trim height value to the axle and follow with a torque of 90 nm (66 lb ft) +60 degrees to the axle bushing through bolts. Push two 12 mm diameter pins through the axle brackets into the underbody until the left and right side axle bracket bolts are properly aligned then firmly tighten all bracket to body bolts to 90 nm (66 lb ft) +30 degrees. The process requires jacking the axle using supports then removing lower shock bolts before lowering the stands to insert Coil Springs angled towards the vehicle's rear. Complete the installation by compressing the springs slightly and tightening the lower shock bolts to 110 nm (81 lb ft). Finish the process by removing the jack stands and relocating brake hose brackets to the body before installing bracket attaching nuts and wheels followed by vehicle lowering.
