This article provides detailed steps for how to remove and replace the driver’s-side CV axle and its axle shaft seal. The axle's inner or outer boots may have split, the internal bearings may be worn (making noise during turns), or ATF fluid may be leaking from the axle shaft seal(s) seated in the transmission differential.
This article does not address replacing the boots on a CV axle shaft. From personal experience, it is not worth the cost, mess, and time. New boots from your local parts supplier (if they have the boots available) usually run $20. Rebuilt as well as new shafts with a warranty cost around $70. If re-booting is the goal, might as well re-boot both the inner and outer boots… which now brings the cost to over $40. This translates to only a $30 cost savings to perform at least a 1.5-hour effort to re-boot, combined with a big grease mess and a lot of paper towels for cleanup.
Regardless of whether the axle shaft is being replaced or not, the inner shaft (or differential) seal should be replaced. Older, high-mileage cars may have seal leakage due to dry rot, hardening with age, or slight damage during a shaft removal or installation job. The cost of a new seal usually runs less than $10.
The outer part of the axle shaft can be separated from the steering knuckle by disconnecting the lower ball joint from the lower control arm. On the Camry and some other models, it requires less time and effort to detach the suspension strut from the steering knuckle. Although most prefer the ball joint removal method, detaching the two bolts securing the suspension strut to the knuckle is easier.
The Camry inner CV axle is recessed into the differential allowing no room to position a pry bar to "pop" the axle out. However, the inner CV bearing housing has three prongs or "ears" that provide a place where a pry tool can push. To gain adequate pry bar leverage against an ear to "pop" the axle shaft, position the pry bar from the top of the engine compartment.
Or see the video below for another method to remove the inner CV axle.
Also, if you're having problems separating the outer CV axle from the steering knuckle, see the video below:
Here's a video on the passenger side cv axle replacement performed on a Toyota Camry. This is a longer axle where the axle is "split" in the center by a support bearing.
Here's a video of a axle shaft removal and seal replacement on a Toyota Highlander. The removal procedure is basically the same:
If you want to salvage your pulled axle by replacing the CV boot, here's a video on how to do it.
Remove the Axle Shaft
- If a high-torque impact driver is not available, the nut tension can be relieved with a 32 mm socket attached to a breaker bar. The axle can be prevented from moving by leaving the front wheel resting on the ground; that is, by not jacking up the wheel.
- Remove the axle shaft cotter pin with pliers.
- Remove the axle shaft nut cotter pin alignment cover.
- Remove the axle shaft nut.
Drain the Transmission Fluid
Draining the fluid before removing the shaft will avoid transmission fluid gushing out the differential after the shaft has been pulled out.
- The drain plug can be removed with a Hex socket.
- Approximately 2.75 quarts of ATF should drain out. The oil can be saved and reused if the no dirt or grim drops into the drain pan.
- Screw back in the drain plug and tighten. Do it now or you might forget.
Detach the Strut Assembly From the Steering Knuckle
- Remove the two bolts and two nuts that secures the strut to the steering knuckle.
- Remove the brake line bracket bolt.
- Jar the axle shaft loose from the wheel hub.
The axle shaft splines may be stuck to the wheel hub. If a few light taps with a hammer does not push the shaft in, partially thread back on the axle shaft nut on to the axle shaft. This will allow harder hammer impacts on the shaft without damaging the shaft threads.
Pull the Outer Axle Shaft Away From the Steering Knuckle
- Wiggle and twist the steering knuckle free from the strut. When the two have separated, the axle shaft should have slid partially out. Pull the shaft out with your hands.
Remove the Inner CV Axle Shaft Shield and the Air Intake Hose
- Removal of this shield will allow pry bar access to the "ears" (pry bar leverage points) of the axle’s inner bearing cup.
- A clear path to the axle shaft can be made by removing the air filter to throttle body intake hose. Removal of the hose should not take more than 5 minutes. *Note: Before putting the hose back on, clean the throttle body plate with some carburetor cleaner solvent.
Remove the Axle Shaft From the Transmission Differential
- Rotate the axle shaft until one of the lips or ears on the CV bearing cup is pointing up. The transmission must be in neutral to rotate the shaft. After positioning the bearing cup, place the transmission back into "park" to prevent the shaft from moving.
- From inside the engine compartment, position the tip end of a long pry bar up against the bearing cup ear. The pry bar leverage point will be the transmission housing.
- Begin applying force to the pry bar… like your body weight. The pulling force being applied to the CV bearing cup must be enough to compress an internal snap ring that prevents the shaft from pulling out and through the differential’s splines. If that does not work, a few sharp hammer blows on the pry bar should provide enough shock force to compress the ring and get the bearing cup moving. Toyota CV snap rings tend to be stronger than snap rings found in other cars (i.e., Honda, Nissan, etc.—Subaru uses compression pins to hold their inner CV axles, but that’s another story).
Remove the Inner CV Axle Shaft Seal
- Seal replacement is highly recommended. A lot of seal replacement jobs could have been avoided if the installer of the new axle bothered to replace the oil seal with a new one. The part is around $10 and only adds a few minutes to the job. Either a small pry bar or seal removal tool will work.
Install the New Inner CV Axle Shaft Seal
- Clean all surfaces and apply a light coat of grease on the transmission seal seat. Position the new seal square in the seat hole. Use a large socket (around 34 mm) to press the new seal in place (or use a bearing press tool like this one). Apply gentle taps on the socket to press the seal and observe the progress. The seal should be flush with the transmission differential housing. Do not allow the seal to recess beyond the housing. If it does, pry it out with your fingers. To prevent damage to the new seal, do not use any sharp tools.
Install the Axle Shaft
- Position the inner portion of the CV axle through the transmission differential axle shaft hole. Rotate the shaft until the splines from the shaft catch the splines inside the hole. The shaft should move in approximately ½ “.
- You need a second person for this next step. With an extra pair of hands, align the axle (including the outer CV bearing cup) positioned straight towards the transmission. Push the shaft towards the transmission (which should compress the inner and outer CV boots), and have your buddy strike the end of the axle shaft gently to get the CV snap rings to compress and move through the transmission’s differential spline. Ensure that the CV nut is on the shaft to prevent damage to the threads. The internal CV bearing must be seated against the CV bearing cup before striking the shaft. If not, the CV boots will be absorbing the hammer blows and the snap ring will not be compressed.
Putting It All Back Together
Reverse the above steps to get things back together. A brief overview:
- Bolt on the inner CV bearing cup shield
- Reconnect the air tube / hose
- Insert the outer CV axle shaft into the steering knuckle. Rotate the shaft back and forth until it aligns with the splines. Then spin on the shaft nut enough to prevent the shaft from sliding out.
- Bolt on the suspension strut to the steering knuckle along with the brake hose bracket bolt.
- Install the wheel and remove your jack and jack stands.
- Torque the axle shaft nut to around 150 lbs. Applying your body weight to the breaker bar should put you close to that torque.
- Fill your transmission with ATF. Double-check the fluid level after the engine is warm.

Questions & Answers
Question: How do you replace the seal on the passenger side of the transaxle of a 2GR-FE (V6) 07 Camry? I noticed that a metal cover ring popped off and was floating around on the long output shaft on the passenger side before the CV axle.
Answer: Passenger side CV axle removal is too involved to explain compared to the driver's side. Passenger side is a split axle design. Basically, you have to remove the center support bearing snap ring then use a hammer and punch the driver the center bearing out of the bearing support bracket.
Question: What kind of oil does a 1996 Toyota Camry CV axle use?
Answer: It doesn't use oil, it uses CV rated axle grease.
Question: Can you please share your expertise on the snap ring axle retainer on the trans end on a Toyota Camry? How does this work?
Answer: It's commonly referred to as a retaining ring; not a snap ring. The ring at the end of the inner CV axle joint, is compressed by applying pressure on the joint shaft when the shaft is being pushed into the transmission. The ring will stay compressed while riding on the transmission spines until the shaft has been fully inserted and "bottomed out." The ring then expands to prevent the shaft from being pulled out unless pulled with force, which will compress the ring.
Question: What if I change the axle seal due to a leak, and it still continues to leak?
Answer: Either the replacement seal was no good or installed incorrectly.
Question: How would I pull the inner axle of my Toyota Camry?
Answer: Use a pry tool and put in between the inner bearing housing and the transmission. You can apply hammer blows to the handle of the pry bar to jar the CV out.
Question: Can I use a CV axle of a 1995 Toyota Camry in a 1990 Toyota Celica?
Question: Can a failing driveshaft cause vibration while idling and can it cause an ABS sensor/ABS module to fail thereby?
Answer: No and no. Driveshaft problems are noticed when the car is in motion. ABS sensors are integrated into the steering knuckle and gets its readings off the ABS ring mounted on the outer CV axle. A new axle should come with a new ABS ring.
