Tacoma lower ball joints are press-fit into the lower control arm and require a proper press kit — do not skip the press; this is a safety-critical joint, and a 2001–2004 recall (NHTSA 06V-249) makes ball joint provenance worth checking before you install used parts.
The Tacoma uses a press-fit lower ball joint that lives in a cup formed into the lower control arm. A castellated nut on top holds the knuckle on the joint stud. When the joint is worn, you'll hear a knocking at low speed over driveway lips, see uneven inner tire wear, or find play when prying between the LCA and the knuckle. A worn lower ball joint can separate without warning at speed — this is the failure mode behind the 2001–2004 Toyota recall, where joints exited the lower control arm and the front wheel folded under the truck.
OEM Toyota (43330-09780 for 2nd gen) is the right part. The 555 brand from Japan ($65) is the same supplier that builds OEM joints for Toyota and is a legitimate budget option. Moog K500036 ($55) is the U.S. aftermarket pick and includes a grease zerk that OEM omits — useful for trucks that see water crossings. Avoid no-name parts and any joint without a clear country of origin.
Second-gen Tacomas (2005–2015) require a specific receiver cup sized for the larger joint body. The Harbor Freight ball joint press kit ($60) covers most cases, but 2nd gen may need an extra receiver from a separate adapter set or a rented cup from a parts store. Confirm fit before you start the job. A shop press with the right cups is faster and safer than the in-vehicle press for the install side.
The job is best done with the lower control arm out of the truck. Pull the LCA, take it to a press, and swap the joint on a bench. Trying to do it in-vehicle on a 2nd gen leaves you working at awkward angles with the CV axle in the way.
