If you torn the ball joint out, you very well could have more damage.
If you plan on doing the work yourself, I would put the car up on stands, and take the front wheel off, and do a through examination of the whole assembly.
Once you have a complete assesement of all of the damage you can go to your local parts house and get the parts.
If you have to replace the lower arm, you will need probably need some specialized tools (like a spring compressor).
After you're done changing parts, you will need to get a front end alignment.

Removing lower ball joint on nissan navara

Remove front wheel (axle stand under chassis).
Remove hub nut (32mm).
Disconnect steering track rod ball joint (leave nut on last few threads for protection 22mm then strike steering arm part of knuckle to shock pin free).
Remove brake caliper & disc. Hang caliper out of way. No need to disconnect brake hose.
Disconnect ABS sensor at top arm area and unclip from mount.
Loosen top ball joint nut. Strike part of knuckle where pin goes through to shock it free. leave nut on loose for now.
Undo lower ball joint pinch bolt & remove. This will probably be seized & will require plenty of penetrating oil & patience to get out.
Next the lower ball joint pin needs to come out of the knuckle so the knuckle can be taken off. You will probably have to beat a chisel into the split portion to open it slightly as the ball joint pin will be rusted in.
Now you have plenty of space to remove the ball joint from the lower arm. Jack vehicle & move stand to under lower arm just in enough to allow ball joint to be removed.
Remove circlip & hammer ball joint out. Use a suitable drift so as not to accidently miss & burr lower arm.
Now the part the perfectionists are not going to approve of.
Heat the hole in the arm gently with a torch (no need to get it glowing red hot but pretty hot!). You will know when its right by trying the old joint (you will be able to get it in position by hand easily without hammering). Now put the new ball joint in place & quickly & drench with cold water before any heat from the arm damages the new ball joint. Fit new circlip.
Reassemble everything in reverse.
There are other ways to do this job but I found this the most practicle for DIYer without special tools.

Ball joint repair and how do you do it

To perform the following procedure, the lower control arm must be removed from the vehicle. Refer to Removal And Installation for that procedure.

  1. Using a screw driver or other suitable tool, pry the seal boot off of the ball joint assembly
  2. Position receiving cup, Special Tool 6758 to support lower control arm when removing ball joint assembly. Install Remover, Special Tool 6919 on the top of the ball joint assembly.
  3. Using the arbor press, press the ball joint assembly completely out of the lower control arm.

NOTE: When installing ball joint in lower control arm, position the ball joint in control arm so notch in ball joint stud is in the direction shown. This will ease assembly of the ball joint to the steering when installing pinch bolt.

  1. By hand, position ball joint into ball joint bore of lower control arm. Be sure ball joint is not cocked in the bore of the control arm, this will cause the ball joint to bind when being pressed into control arm.


  1. Position control arm with installed ball joint, in an arbor press with Receiving Cup, Special Tool 6758 supporting the lower control arm. Then center Installer, Special Tool 6908-4 on the bottom of the ball joint
  2. Carefully align all pieces. Then press the ball joint into the lower control arm until it is completely seated against surface of lower control arm. The ball joint is correctly installed when there is no gap between the ball joint and the lower control arm. Do not apply excessive force against the ball joint or the lower control arm.
  3. Install a NEW seal boot by hand as far as possible on the ball joint. Installation of the seal boot is to be with the shield positioned as shown.

CAUTION: Do not use an arbor press to install the sealing boot on the ball joint. Damage to the sealing boot will occur if excessive pressure is applied to the sealing boot when it is being installed.

  1. Place Installer, Special Tool 6758 over seal boot and squarely align it with bottom edge of seal boot. Apply hand pressure to Special Tool 6758 until seal boot is pressed squarely against top surface of lower control arm.

CAUTION: A replacement ball joint is not pre-lubricated. Properly lubricate the replacement ball joint using Mopar Multi-Mile grease or an equivalent. Lubricate ball joint after seal boot is installed but prior to top of seal boot being pushed down below notch in ball joint stud. Air must vent out of the seal boot at notch when grease is pumped into ball joint, failure to do so will balloon and damage seal boot. Do not over grease the ball joint, this will prevent the seal boot from pushing down on the stud of the ball joint.

CAUTION: After the ball joint is properly greased, clip the end of the grease fleeing off below the hex. The ball joint seal boot is non-purgeable and further greasing is not required and can result in damage to the seal boot.

  3. On Eldorado and Seville with 4.6L engine, remove the road sensing suspension position sensor from the lower control arm.
  4. Remove the cotter pin and nut from the ball joint stud. Use ball joint separator tool J-36226 or equivalent, on Deville and Fleetwood or ball joint separator tool J-35315 or equivalent, on Eldorado and Seville, to separate the ball joint from the steering knuckle.

      Fig. 2: Installing the bolts in the lower control arm 91048g06.gif
      To install:
  6. Attach the new ball joint to the lower control arm with 3 mounting bolts and nuts.
    1. On Deville and Fleetwood, the bolts must be installed from the top of the control arm.
    2. On Eldorado and Seville, the bolts must be installed from the bottom of the control arm
    3. Tighten the nuts to 50 ft. lbs. (68 Nm).
    4. On Catera, the bolts must be installed from the top of the control arm.
    5. Tighten the nuts to 26 ft. lbs. (35 Nm).
  7. On Deville and Fleetwood, tighten the stabilizer bar link nut to 13 ft. lbs. (17 Nm).

  9. On Deville and Fleetwood, tighten the ball joint nut to 88 inch lbs. (10 Nm). Then tighten the nut an additional 120°, during which a tighten of 41 ft. lbs. (55 Nm) must be obtained.
  10. On Eldorado and Seville, tighten the ball joint nut to 84 inch lbs. (10 Nm). Then tighten the nut an additional 120°, during which a minimum torque of 37 ft. lbs. (50 Nm) must be obtained. If the minimum torque is not obtained, check for stripped threads. If the threads are okay, replace the ball joint and knuckle.
  11. On Catera, tighten the pinch bolt to 74 ft. lb. (100 Nm).
  12. Install a new cotter pin. If the cotter pin cannot be installed because the hole in the stud does not align with a nut castellation, tighten the nut up to an additional 60°to allow for installation. NEVER loosen the nut to provide for cotter pin installation.
  13. On Eldorado and Seville with 4.6L engine, install the road sensing suspension position sensor to the lower control arm.
  14. If necessary, remove the CV-joint boot protector tool.
  15. Install the wheel and tire assembly and lower the vehicle. Fig. 3: Separating the ball joint from the steering knuckle 84208016.gif

2001 Sebring Sedan LX, 2.7l V-6, VIN Code U Lower balljoints: Can the front left and right lower ball joints be pressed into or out of the lower control arms on this vehicle? I'm being told by my mechanic...

Sounds odd... Rikkalan,

(but it appears AMAZON agrees with your mechanic)

Just go to ROCKAUTO and look up your parts...

If the entire arm needs to be replaced the separate ball-joint will not be listed...

Hope this helps!!

Very common BMW problem. The front lateral arms that support the front to rear motion of the wheel. BMW calls it the upper, lower support arm. Two arms connect there. one left to right (think typical lower control arm, and this arm) It has a ball joint that connects to the lower most part of the strut and extends rearward to the rear crossmember and has a large bushing pressed into the arm. You can replace just the bushing if the ball joint end is ok. Bushings are about $45 each and you will need a press.
