    OVERALL. Nice big project today swapping out both CV axles in under 5hrs. I'm fortunate to have access to a shop lift & pneumatic tools. Driver side CV axle was bad & at 246k miles. Rationale- I'm estimating Prius probably won't make 300k miles, cheap parts, & that i was already under the vehicle; for fun-- I decided to swap them both out. It didn't affect any of the steering, so a wheel alignment was not necessary.

    LESSONS LEARNED. I should've ordered new axle nuts, as 1:2 old ones were beat up pretty good coming out.

    1. LIFT & REMOVE TIRE. I lifted the car; starting with the driver side CV axle, I removed the wheels and removed the axle nut (with penetrating oil). I had to use a pin punch to bend out the dent in the axle nut. With a dead blow hammer I hit/pushed the axle inward to evidence free play away from the bearing -hub & knuckle.
    2. FREE-UP KNUCKLE. I removed two hub bolts connecting the driver front strut & upper knuckle. I left alone the bottom bolt (attached to the ball joint) & outer tie rod. This allowed me to bend back the knuckle and tease out the CV axle with ease. Also disentangled the brake lines attached to the knuckle.
    3. REMOVE CV AXLE. With the CV axle outer end dangling on the knuckle, I went under the car to access the inner CV axle. With a long pry bar, I loosened free the CV axle from its clamped transaxle attachment. Some ATF leaked from the CV axle removal, but I caught it.
    4. REPLACE NEW CV AXLE. The CV axle didn't fully seat, so I pushed the remaining 2cms in with a pry bar & hammer. There are notched ledge points on the housing of the inner CV axle. I placed white lithium grease on outer splines for bearing hub contact.
    5. RESEAT KNUCKLE. In reverse, I replaced the two hub bolts & brake lines connecting front strut & upper knuckle- torque specs- strut bolts 177ft lbs; axle nut 159ft lbs
    6. REPLACE TIRE. Since I was already under the car, I rotated the tires back to front. Torque lugs 77ft lbs.
    7. REPEAT OTHER SIDE. Now for doing the same procedure for the passenger side CV axle.
    8. REPLACE ATF FLUID. I performed a routine AFT fluid exchange using 10mm hex wrench to remove both fill bolts. My last ATF fluid exchange was 35k miles ago.
    9. ROAD TEST. A week post procedure, all things fine: no alignment problems, no weird noises, etc.

    Very thorough right up! Excellent work. It's been a while since i saw use of old school pneumatic rattle gun. Wonder if there's a market for my ¾" Ingersoll Rand boat anchor.

    Very good write up!

    I just beg of you to replace your 12 year old struts and shocks in the future. You will thank me later
