A clicking sound on tight turns is a torn outer CV boot that's lost grease and chewed the joint; replace the whole shaft, not the boot, once the joint has been running dry — the boot fails first, but the damage is already done by the time you hear noise.
Tacoma CV axles are the IFS front-half-shafts that connect the front diff to each front hub. Two main generations to know: 1995-2004 (1st gen) uses 43430-04020, 2005-2023 (2nd and 3rd gen) uses 43430-04071. Both are 4WD-specific — RWD-only trucks don't have front CV axles. The outer joint (at the hub) takes the most abuse because of steering angle; the inner joint (at the diff) plunges in and out and rarely fails on a stock truck.
Diagnosis is fast. A click or pop on tight slow turns (parking lot) is a worn outer joint. A vibration at speed under load is a worn inner joint or, more commonly on lifted trucks, an over-angled inner joint without enough plunge room. If the boots are intact and the joints feel tight by hand, it's not the CV axle — look at wheel bearings or lower ball joints next. On lifted Tacomas at 3"+ lift, the front CV operating angle gets steep enough that the inner joint binds at full droop. Aftermarket upper control arms or a diff drop kit pull the inner angle back to a safe range.
Replacement options divide cleanly. OEM Toyota at ~$380 each is the longest-lasting choice — Toyota CVs typically run 200k+ miles. Quality aftermarket reman from SurTrack ($130) or new from GSP ($150) is the budget choice and works fine for a daily driver. If you're running 33s+ on a 3"-lifted truck and you wheel hard, look at the YotaShop NCV69142XDP extreme-angle shaft for 1st-gen trucks — it tolerates more articulation than stock at a price between OEM and budget aftermarket.
Install is straightforward but requires breaking the axle nut and separating the lower ball joint or tie rod. The big axle nut (30mm or 36mm depending on year) is torqued to 174 ft-lbs and may need a breaker bar with a cheater. Don't reuse the axle nut — it's a single-use stake nut. Get a fresh one. Final torque on the nut is critical — too loose and the hub wobbles, too tight and the wheel bearing overheats.
