A clicking or popping noise that gets louder when you turn means the outer CV joint on your front axle is worn — replace the whole axle assembly rather than rebuilding the joint. A torn boot that hasn't started clicking yet can sometimes be saved with a reboot kit, but a reman axle assembly is the higher-value fix at $85–240 a side. Plan on 2–4 hours per side. This is front-drive only — it applies to Tacomas in 4WD, and the symptom shows up most when you turn under power.
The front CV axles on an IFS Tacoma are wear items, and the failure pattern is consistent enough to diagnose by ear. A rhythmic click that speeds up with road speed and gets worse on turns is a worn outer joint. A vibration under acceleration that smooths out when you coast points at the inner joint. Either way, once a joint is making noise the grease is contaminated and the fix is replacement.
**Reman assembly beats rebuilding the joint.** You can buy a CV joint reboot kit for $20 and rebuild a joint that only has a torn boot and clean grease inside. But once a joint clicks, the bearing surfaces are worn and a reboot won't quiet it. A complete reman axle assembly ($85 a side) comes with fresh joints and boots on both ends, and it bolts in as a unit. For a daily-driven truck, the reman assembly is the right call on cost and time. If you want OE durability, Toyota's assembly runs around $240.
**Catch torn boots early.** The most common reason these axles die young is a split outer boot that throws grease and lets grit into the joint. Inspect the boots at every oil change. A boot that is cracked but not yet split, with grease still inside, is a candidate for a reboot kit and buys years. A boot that has flung grease across the inside of your wheel is past saving — the joint is already contaminated.
**The axle nut is torqued hard.** The 30mm or 36mm front axle nut is staked and torqued to roughly 174 ft-lb on most Tacomas. Break it loose with the truck on the ground and the brake held before you lift, or use a long breaker bar with the hub locked. Always fit a fresh nut on reassembly — the staked collar is a one-time-use feature.
**Safety — support and joints.** Raise the truck and set it on rated jack stands before any of this. You will be separating a lower ball joint or tie rod end to swing the knuckle out and pull the axle, so a pickle fork or proper separator is needed. Support the lower control arm with a jack while you work so the spring load is controlled. Torque every fastener to spec on reassembly — front suspension and axle fasteners are not the place to guess.
