No they are part of the lower control arm in a leaking be purchased with the control arm itself
Hello and welcome to JustAnswer!
You can replace the lower control arm bushings, and they are a very common failure on the PT Cruiser and Neons. Replacing the lower control arm has never been necessary. The part number for the bushings is(NNN) NNN-NNNNC and they run $42 each.
The first step to replacing the bushings is removing the control arms. To do this you will need to remove the bolt that holds them to the subframe in the front, the large bolt that holds them in the rear. You will need to remove the bolt holding the lower ball joint to the steering knuckle and separate the ball joint. You will need to remove the sway bar links from the control arms.
I find it beneficial to remove the strut clevis bolts that hold the steering knuckle to the strut. This will allow you to pick up on the knuckle and remove/install the ball joint into the bottom of the knuckle easier.
Once the control arms are out you will need a few special tools to remove the bushings from the control arms. These include adapters to adapt a ball joint press to the bushings to press them in and out. You may also be able to take the control arms and the bushings to a machine shop and have them press them in and out.
The Miller special tools to press the joints in and out are 8373-1, C-4212F (ball joint press), 8373-2, and 6760.
These are the ones in the rear of the control arm, the ones that mount the rear of the arm to the subframe. These are the bushings that are replaced on a very regular basis.
You can't heat the old bushings up and remove the rubber. The rubber is bonded to the metal outer shell of the bushing and the entire bushing has to be replaced. The failure of these bushings always comes from the bubber ripping out of the metal shell. The bushings have to be pressed out and in with tools and a ball joint press.
Raise and support the car.
Remove the tires.
Remove both sway bar links. Hold the nut on top with Vice Grips and remove them by loosening the 15mm bolt on the bottom of the link. Once both are removed then you can swing the sway bar down and remove the rest of the link bushings.
Remove the bolt and nut that hold the ball joint into the steering knuckle.
Separate the ball joint from the knuckle.
On the right side you will have to remove the lower torque strut to get to one control arm bolt. Remove the two bolts that hold the torque strut at each end, one at the subframe and one near the oil pan.
Remove the control arm bolts. There is one that goes into the subframe horizontally at the front, and one that goes in vertically at the rear.
Remove the control arm.
Install the remover/receiver, special tool 8373-1, into the cup of the ball joint press and tighten the set screw. Install the remover driver, special tool 8373-2, on the tip of the ball joint press screw.
Place the lower control arm outer flange against the receiver. Tighten the screw on the press until the driver contacts the outer circumference of the bushing. Continue to tighten the screw until the bushing is pressed completely out of the lower control arm. Remove all tools.
Start the new bushing in the lower control arm by hand. Position the bushing so the voids in the rubber are aligned in relationship to the ball joint. The gap in the rubber needs to point toward the ball joint.
Install the receiver, special tool 6760, on the tip of the ball joint press screw.
Place the lower control arm flange against the cup area of the ball joint press and tighten the screw until the receiver contacts the outer circumference of the bushing. Slowly tighten the screw until the bushing bottoms out in the lower control arm bushing bore.
Remove all tools.
Reinstall the lower control arm in the car and perform an alignment.
