Parts Cost:
$50 from Rockauto
$100 from Most Other AutoParts stores
$500 from dealer
Labor Cost: (LosAngeles)
Free (DIY, on your driveway). Requires 2 jack stands, 2x4 or other wheel chocks, jack (vehicle's jack will do), Metric socket set, screw driver, and one large socket bought at AutoParts for your Axle Nut. And a few wrenches from 12mm-18mm. C-clamp is helpful but not required. Needle nose pliars (for axle cotter pin.)
$100 Indepedent Mechanism
$150 Pepboys, Goodyear, Most Full Service Tire shops (full garage, not just tires)
$200 High Price Limit
$250 Dealer Labor
Doing this job at home is not that hard, though the passenger side axle has some challenges. Driver's side is easier.
1. Loosen Wheel Lognuts (break free, leave in place)
2. Chalk rear tires with wheel chalks or wood. (Harbor Freight sells wheel chars for $6). And tools ($15), and stands ($35).
3. Jack car (floor jack, use front cross member, there is a jack bulge that is obvious)
(tire jack. Use on side crimp, at the side crimp cutout behind front tires.
4. Place jack stands. Lower onto jack stands.
5. Use jack's lugwrech to remove lug nuts completely, remove wheel and tire.
5. Use C-clamp to compress outside break pad to back of caliper. (This makes slack in the caliper making it easier to remove.)
If no C-clamp, use a screwdriver, and wedge it between steel and out break pad for the same purpose.
6. Remove rear caliper bracket bolts with entire caliper and pad assembly. Slides off rotor if the pad has been loosened. Can "knock" off with hammer if the pad has not been loosened in step 5. Have a wire hanger around, and pull to a double, bend both ends, and use as a hanger to hang the caliper out of the way from the struct spring there in front of you. (Do not let the caliper hang from its rubber hose.)
7. Remove the rotor. If you are luck, its loose and you just pull it straight off. If not lucky, then back it with a hammer in the center part (just for shock. You are hammering "IN", even though you will remove "OUT", at the center, not on the pad/rotor surface. Bang it a lot with the hammer until the shokc loosens up the rust that is holding it place. The rotor rusts, against the aluminum hub, and forms sort of a rust glue. Several wacks with the hammer will usually free it up.
8. Remove Anti-lock break sensor from wheel knuckle. This is the "electric code" like wire that ends in a plastic or steel plug with a 12mm wrench cutout on it. Spray some WD40 or PBBlaster on it, and then unbolt it. The wiggle pull, wiggle pull, until it comes out of the hole it is shoved into in the wheel knuckle. Just allow the sensor to hang on the wire, or if very caution oriented, put a plastic sandwich bag on it, and twist on a bag close.
9. Remove axle cotter pin, just outside of the Axle nut.
10. Remove the axle nut. This is easiest done with a battery or air powered impact wrench. Lacking those, a large breaker bar is needed, and the appropriate large socket for your axle nut. Large sockets are available Ala-Cart at Autozone and Oreilly's, and Napa, etc.
11. Remove the strut cross mount bolts and nuts (two of them) that hold the strut to the wheel knucle. No precautions need be taken here.
12. Use a large screwdriver or small crowbar to wedge the struct out of the wheel knuckle.
13. Push the axle through the wheel knuckle (inward) as far as it will go. It may not go all the way.
14. Turn the wheel knuckle outward (if needed, turn your steering wheel), and push axle through the knuckle. The axle will go through, but you will have to rreposition the CV joint nearest the wheel and pull on the knucle, and push and prod to get the axle end tip to clear the knuckle.
15. Be careful with the CV joint bladder cover if you are keeping the CV joint. Otherwise, don't worry about it. (e.g. don't tear it, or tear it more if you intend to keep it for some reason.)
16. Unbolt the inner mount screws on the CV axle at the mid-point support. These are idiotically inside-out bolts. Both are very difficult to get at, particularly on the CA version of the Maxima (it has a second Catilytic converter on each bank that is in the way.) I have found a long thin ratchet, with a low-profile socket on it works best. (Harbor Freight ($20), long thin double ended ratchet, Oreilly Auto, has a nice low profile socket set $15). Thin "service" wrench can also work if they are not too thick at the opening.
17. Once unbolted, top bottom side. (3 bolts) Then, use a crowbar to work out the axle from the mid-point mount. (Many youtube vids).
18. Once it moves some, then grab axle and just "yank it out".
Installation is the Reverse Accept ALSO:
a. Put grease on the outside of the midpoint bracket before install, so it will slip into the break easier.
b. Put grease on the axle end, so it will mate with the wheel hub easily, and not rust over time.
c. Be careful when inserting the inner end back into the tramission transaxle (differential) and try not to rub the rubber seal there, its fragile, and if you tear it, then you have to replace that, and its hard to get to, especially on the CA version.
d. Eyeball the spleens on the axle, and the transmission using a flashlight. Try to get close to lined up as you insert. Then turn gently until you can feel the spleens seat. Once partially seated, then sort of "ram" it in with your HANDS. There is a C-clip at the ends of the axle that needs to seat properly to "lock" (lightly lock it in. Its not really "in" until that clip seats. DO NOT EVER USE A HAMMER! If you bend your meting spleens in the transmission differential cause you used a hammer, you will be new transmission service sorry. NO HAMMERS!.
Otherwise reverse steps.
Pull the knuckle down and back as much as you can, and bend the CV joint at the wheel knuclke, to get the axle end into the wheel knuckle.
Turns the hub to seat the splines.
Push the knuckle up to push the axle through more.
Use a jack under the wheel hub to jack it up a bit so that you can line up the strut bolts. Get them as close as you can, hand inserted is best, but sometimes close and a hammer is what it takes to drive the bolts through.
Finish reversing steps.
HIGHLY recommend a torque wrench for the axle nut. You need a BIG one for this nut, as it is 200 ft. lbs. of torque. (A LOT). Min is 190 ft. lbs, and max is 210 ft. lbs. (That is NOT inch pounds, its ft. pounds.)
1st timer can do it in 3 hours.
Experiences person can do it in 30 minutes.
