How do you remove a lower ball joint on a nissan navara d22 4x4

You can probably press it out using the tool - it usually take yet another tool to press it back in.
Now many store (rockauto for sure) has the lower control arm AND new ball joint for $27 -

Here's a link to the lower ball joint,it tells you about a fitting to be greased,as you see the ball joint has a hole at threads where greasing fitting will be.It will be best to jack up and remove tire to grease,look for other grease fittings,wipe up excess grease.Also check ball joint for wear,may need replacing.

to remove lower control arm bushings you need to remove control arm from vechicle have control arm bushings pressed out.you need to remove disconnect torsion bar,remove shock absorber,disconnect stabilizer bar link, remove axle half shaft, remove the lower ball joint, remove control arm mounting bolts, then remove lower control arm.

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.

1. Remove the wheel and tire assembly. For additional information, refer to Section 204-04 .

1. Remove the suspension lower arm ball joint cotter pin.

1. Remove the suspension lower arm ball joint nut and separate it from the wheel knuckle.

May have to leave nut partially on and hit the nut hard with a hammer to knock the tapered stud down and out. May have to hit side of knuckle to help get it to drop. or rent a pickle fork to drive between the bal joint and knuckle.

1. Remove the suspension lower arm ball joint to suspension lower arm nuts and remove the ball joint.

Disconnect the caliper and mount, and hang it aside. Unbolt the 5 or 6, 6mm allen head bolts from the hub. Pull the hub out and remove the snap ring and washers behind it. Loosen the upper ball joint nut a little and break the joint free. Support the lower control arm with a jack and loosen the lower ball joint nut and break it loose also. With the lower control arm supported, remove the upper ball joint nut and slowly remove the lower control arm support (jack). The shock will retain the torsion bar and you can now remove the lower ball joint nut and slide the knuckle off the ball joint. You will be able to move the knuckle and axle around enough to give you access to the four bolts securing the ball joint

You will have to remove it and replace it with a new one. The general steps for doing that is: 1)remove the tire 2)remove the caliper and rotor 3)remove the outer tie rod from the spindle 4)remove the axle nut 5) remove the cv axle 5)remove the nut on the ball joint 6) bang ball joint out and press in a new one. Then reassembly is exactly the reverse as disassembly.

You need a ball joint removal tool to remove it and to take it out, if you can't rent the tool your not going to be able to get it out because it is press fit into the A arm

The entire control arm is supposed to be replaced on those when ball joint fails. Did you manage to buy another ball joint only?

Hi,
Remove the castle nut on top of the ball joint that secures the ball joint to the spindle. separate ball joint/lower control arm from spindle.Remove lower control arm bolt attatching control arm to subframe/engine cradle. Remove control arm. Replacement is recersal of the removal. Nissan/Infinity ball joints can not be pressed out or in. They are replaced with the whole new lower control arm as one (On most Nissan/ Infinity vehicles, although some exeptions apply. Hope this helps.
