Hey all, it's been awhile. Been too hot to work on the truck much, and it's just starting to become reasonable again.
So 10,000 miles after doing my big gear ratio change by installing D41 parts in my D40, I found the brakes to be subar. Going to bleed the brakes I found a whole lot of sludge at each front corner. Turns out that the two CV axles were handled poorly and the boots were damaged enough that they were able to pinhole-leak eventually. Driver's side outer boot and passenger's side inner boot. After pricing boots and looking at the process I decided to just order a pair of Nissan CVs, and did the install today.
Because I've been in there due to the previous gear ratio change only a little while ago it wasn't too bad save for the excessive mess from the leaking boots. None of the hardware gave me trouble at least. I did revisit videos on how others have done it and I have to say that they all take off more than required, at least on a truck with the Bilstein 5100s on the 3rd position. Here's the steps I followed:
- before raising off the ground, remove the CV cotter pin, break the CV nut loose, and back off until CV shaft threads are no longer visible at the end
- normal raising and removal of wheel
- remove brake caliper and use some wire to hold it up out of the way
- clean up as much of the mess from the leaking boot as possible
- remove upper balljoint cotter pin and loosen the nut until no threads visible below
- Unhook the rubber grommets holding the ABS wiring from the three places they attach between the connector an the sensor
- variously smack the steering knuckle at the upper balljoint and the underside of the UCA to break loose the balljoint from the steering knuckle
- remove the CV shaft nut from the end of the CV shaft
- turn the steering all of the way to the opposite side (if driver's side, turn to the passenger's side)
- remove the upper balljoint nut and separate the UCA from the steering knuckle
- Wiggle on the CV behind the steering knuckle while rotating the steering knuckle down, eventually the outer end of the CV can be worked loose of the hub and bearing
- pull out on the CV at the center shaft hard, it will reach end of travel and cause the inner spline to disengage from the differential
- finish cleaning up the area from all of the grease that got everwhere
- Slide the new CV shaft into the differential until it clicks into place, may require a bit of force
- manhandle the outer end back into the splines in the hub
- Tilt the steering knuckle back up to the upper balljoint, wiggle on the CV shaft to help it seat into the splines on the hub
- Install the upper balljoint nut finger-tight
- Center the steering
- Install the CV nut and spin it on until it stops finish seating the splines
- Tighten the upper balljoint to 58 ft.lb
- Insert a screwdriver or other obstruction into the brake rotor where it will stop against the caliper mount and tighten the CV nut to 101 ft.lb
- Reinstall both cotter pins
- Reinstall the ABS sensor grommets into their respective slots
- Clean the brake rotor and anthing else that might need cleaning and then reinstall the caliper
- Reinstall the wheel and lower back down
It was
not necessary to remove the ABS wire entirely, or to remove the caliper bracket, or the brake rotor, or the dustshield, or the strut assembly, or even the antisway bar.
I didn't take any photos, sorry. It was messy and wanted to get it done quickly. Probably took us three hours to do both sides, my dad did the clean stuff while I handled the messy stuff and brute force stuff. It's more than a one-person job but not much more than a one-person job.
