How To: Replace Passenger CV Shaft with pictures

I started with the passenger side:

Here are my new parts. 2 - Cardone CV Shafts; 36mm axle socket (35mm also needed if you're removing OEM shafts); Synthetic packing grease; 2 qts Mobile 1 75r90 (not used for CV chaft change - just for the differential)

1) set your emergency brake and chalk the rear wheels
2) loosen front lug nuts
3) lift the front end and support the truck on jack stands
4) remove front tires
5) remove strut assembly
..... a) loosen the two upper nuts (15mm) but do not remove them yet
..... b) loosen the lower nut (15/16ths) back the nut off until there are no longer any threads exposed
..... c) lap a pickle fork into the opening between the lower shock mount and the control arm as pictured
..... d) using a heavy hammer hit the end of the tapered post (make sure the nut is to the end of the threads and your hitting the nut, otherwise you run the risk of fowling the threads on the end of the post.) It only take a few decent smacks to get it to pop free
..... e) remove all three nuts and remove assembly

6) Remove the brake caliper and bracket in one piece (18mm)

7) remove the brake line bracket (10mm)

8) set the brake caliper assembly out of the way (I had enough room due to the body lift to set it on the frame, you may have to hang it up out of the way. Be careful not to strain the brake line.)

9) remove the wheel spacers (if applicable) and the rotors

10) remove the speed/ABS sensor (5mm allen wrench) unclip and move it out of the way

11) remove drive axle nut (35mm stock / 36mm aftermarket) use a prybar to hold the hub stationary

12) remove the three hub assembly bolts (normally you will have to work around the CV Shaft, however mine was broken and has previously been removed)

13) remove the front axle 4WD disconnect from the engine block (4 - 15mm bolts) and disconnect axle from it. I used the pickle fork to separate the two pieces.

this is a good opportunity to clean out the old the old grease in the front axle 4WD disconnect

14) replace front axle 4WD disconnect to the engine block

15) remove the nut/bolt (15mm) on the upper ball joint and separate from the upper control arm

16) install new CV Shaft and re-install everything in reverse

Differential oil goes in the differential on the driver's side. A different project that's been documented elsewhere.

The answer is no because you aren't changing any part of the suspension geometry that's involved with alignment.

Thanks for the writeup Regulator1175! My inner CV boots are leaking grease even though there are no tears in the boots and I'll be using this writeup to help me change the half shafts once they totally crap out.

Really nice How to. Couple of questions

What type of grease did you use in the disconnect?

I have what feels like a significant amount of play in either my tripot joint or where the cv shaft enters the disconnect. If it is in the disconnect, what is the remedy?

I used Valvoline Synthetic packing grease, The can is in my first picture.

If you have slop at the splined disconnect I would venture to guess that you need to replace one or two of the bearing assemblies, Part number 26053326. I would also replace the outer seal at the same time, part number 12479055.

They are parts number 1 (seal) & 2 (bearing) in assembly 56 in the picture below.

I noticed today that both of my boots have a very small tear right behind the clamp and a small amount of grease has leaked. Im stuck on if i should get the replacement boot that has a slit that slides over and gets glued and sealed or the o.e.m which i would have to tear it appart to slide the boot on...im going to try and put some rtv for a temp fix cuz its darn cold outside.
