Somewhere in the list of comments someone said they could not get the driver side axle out. 1A Auto said that their video is for the passenger side and that the driver side is the same. That is not true. For the passenger side one pulls the axle out of the transmission first then out of the bearing. On the driver side you have to pull the axle out of the wheel bearing first then the transmission. That is because the shaft that goes into the transmission is three times longer on the driver side than the shaft that goes into the transmission on the passenger side. You won't think it will come out without taking the lower ball joint apart but it will. Here is how it works.. If you purchase both front axles you will see that the transmission side is different for the two axles, the passenger side has the spline inside the inner axle while the driver side has the spline on the outside like the bearing side. That means for the driver side you have to pull the axle out of the wheel bearing first and then cock the two joints to get the wheel side axle to bypass the knuckle. I fount it a PITA and found I had to keep adjusting the wheel turn until I found the right angle to get enough clearance. It took me and another person an hour to get it out even after I had the knuckle apart from the top ball joint. Then you pull the axle out of the trans. For some reason it went in a lot easier. Put it into the trans first then bend the axle boots as much as possible and there is just enough clearance to get it past the knuckle and into the wheel bearing.. On the passenger side the side of the axle that goes into the trans is shorter than the driver side and there you pull it out of the trans first. It coms out a damn lot easier than the driver side. Good luck.

[@shannoncoffey4298]

One more comment. It took about 30 good hard blows with a full size sledge hammer to separate the upper ball joints. I thought they would never come apart but they did just like in the video, but my 3 pound short handle mini-sledge did not do the job. Get or use a full size sledge. I think a full size sledge is about 10 lbs.

I'm about to pull the driver side cv axle, it looks like there is a retaining ring on the end of that spline inside the differential, is that correct? If so, wouldn't you have to pull the diff cover off and pull the ring there? See diagram: (ring is labeled 3Z498) parts.ford.com/shop/en/us/transmission/powertrain-engine-parts/shaft-front-axle-7813407-1

[@kevinbishop799]

Hey, I hope you see this, I just wanted to tell you thank you! You helped me out so much and I really appreciate it.

[@Dyna78]

The retaining ring is basically a circular spring that expands into a groove on the gear in the differential. The groove must have slightly angled sides, because when you pry on the axle to get it out, the ring "springs" and compresses enough to let the axle slide out.

[@AgentFrybread49]

Mike I'm working on my 2002 mountaineer and the passenger CV axle will not release from the rear differential. Had no rear leaks either just fyi. I'VE USE A SLIDE HAMMER SETUP AND PUNCH AND HAMMER NO LUCK..... PLEASE HAVE SOME INSIGHT.

[@razr199]

You definitely make it look easy. Great video bud. Yeah I have a 04 Explorer. I had a hole in my boot. My neighbor said you loose your grease and then the u joint goes bad. The abs light come on and the 4wd light was flashing. Thank you so much for your videos.

[@vintagesurvivor]

Looks like a new upper A arm magically appeared :) When doing driver side, remove the caliper for clearance, makes it a lot easier on that side.

[@johnjames77]

I am trying to change out the hub s that I bought from 1A Auto. There is no tool that will get on the 15mm 3 bolts that hold in place because the CV shaft is in the way. That is what brought me here. I have been pounding on the part that is connected to the upper ball joint and it does not fall off like it did for you. Are there any other methods beside a bigger hammer to break it free?

[@johnjames77]

I ended up using a pitman arm puller and it came off .

[@hotdogs5265]

Thank you. I purchased from 1Aauto before and its a great parts and service. Highly recommend.

[@Mijupac]

Hi, great video. I do have one question though. I recently did a front bearing job on my 2005 V8 Mountaineer and the specs I found called for the hub nut to be torqued to 100 ft pounds. Can you please clarify? Thanks.

[@hamiltonbaptiste8989]

Working on a 2014 Explorer right front axle, got an axle from Ford and it came with extra brakets for the new axle supposedly need to know about brakets.

[@hermanbeuttenmuller1751]

This is very helpful, thank you . Replaced them but still have a popping in front end when i turn sharp not as bad but it is sill there some what.

[@1AAuto]

+Herman Beuttenmuller You may want to check the ball joints to see if they need to be replaced. Here's a link to all of the parts that we carry for a Ford Explorer if yours needs to be replaced goo.gl/fETyVC

[@robertlugtu9059]

Additional help to make easy while working around it, removed the sway bar link 2:53 before loosing the "nut" on 1:35 so there is no tension on the sway bar link nut

[@1AAuto]

+robert lugtu thanks for the helpful tip!

[@ramondawashington9770]

Would it be about the same as doing the rear driver side

[@1AAuto]

+Ramonda Washington This procedure might be different for your application. We do not currently have a how-to video for this particular year, make and model. Thank you for asking! 1aau.to/m/Shop-1AAuto-c

Can a bad CV axle cause vibration

[@davidbrucemusicvideo]

thank you for this video. As always, you guys are a great help. You have just let me know that I will not be taking this job on myself. I will bring it to a local shop!! Ha!

[@1AAuto]

Thank you for watching! Glad to be of help. Please let us know how the repair turns out. 1aauto.com 888-844-3393

[@monroy2429]

Does the front diff fluids leak out once you remove the CV joint??

[@kubotaman85]

A little bit will leak out but not much to worry about

[@steveh8224]

Do you have a video on how to replace the front outer axle housing bearing and seal? And are they pressed in?

[@1AAuto]

+Steve H We currently do not have an auto repair video that covers this particular repair. We will keep this request in mind in the event that we need to make this repair in the future. 1aauto.com

[@steveh8224]

1A Auto Parts is there a roller bearing inside the axle housing where you pulled the CV axle out of?

[@josephmolion4345]

Is this the same procedure for a 2000 Mountaineer V8?

[@1AAuto]

This video is applicable to the 02, 03, 04, 05 Ford Explorer or Mercury Mountaineer, but you should be apply to apply some of it to your 2000 model. +Joseph Molion

[@kubotaman85]

Thank you for this video. It was very helpful and informative. The only pain in the @$$ I had was getting the knuckle back up on the upper control arm other than that it went pretty smoothly

[@amirkalaoun]

hello, doesn't the front diff fluid leak out when the axle is pulled? thanks!

[@Dyna78]

The axle is at roughly the same level as the fluid fill plug, so if the vehicle is level, no fluid should leak out. If the vehicle is tilted lower on the side you are working on, then some fluid could leak out, but not much.

[@jamesrichardson1366]

I'm working on a 2004 ford explorer eddie buaer and I bought a 30mm socket for the exel nut but it's to big I'm thinking either a 28,29mm?

[@kubotaman85]

30 MM should work. You have to be sure you buy the 30 MM axle nut socket at the parts store

[@maxxmatlock212]

James Richardson it's a 29mm. It's more of a snug fit than 30. I just changed both front hubs

[@shannoncoffey4298]

@@maxxmatlock212 Could not get a 29mm to go onto the nut, but I will admit the 30 mm was rather loose.

[@Dyna78]

I purchased new spindle nuts to use on this job, which have a 30mm hex. The original spindle nut hex measured 29.4mm and was very loose with a 30mm socket, but it worked. The new axle I installed came with a nut (luckily!) and the thread size was larger, too big for the nuts I purcuased. The nut that came with the axle needed a 32mm socket. And for comparison, when I changed hubs on my 2000 explorer, those nuts were 28mm! So I'd say the best way to know is to measure what you have/try some different sockets to be sure, as it seems that there may be no standard size, or it was changed frequently.

[@mr.delahoya115]

How much does the shop charge for this to be done?

[@victoryoung9178]

I can't seem to get the cv to press snug up angainst the axle housing. Just about an eighth or quarter of an inch gap that shows the rubber seal inside.

[@ourcarproject3059]

hit it

[@Dyna78]

I found that the 'snap ring' on the new axle was spread out a bit more, with sharp edges. I removed the ring and used a file to slightly bevel the outer edge of the ring on the side that will be going into the gear inside the differential. Then I slightly compressed the ring to make sure it hadn't spread out too much, then put the ring back on the axle with the slightly beveled side towards the differential. This seemed to help the ring compress a little easier and I was able to get the axle to go all the way in and let the ring seat in the gear.

[@TheMemyselfandme]

What is the part called that you are sliding the drive axle back into.

[@1AAuto]

+Michael Harris There's a wheel hub bearing assemble attached to the steering knuckle, and the other end goes into the transmission. Hope this helps you out. 1aauto.com

[@TheMemyselfandme]

There is a part like a stub axle that goes on the end of the cv axle on the end that goes into the differential. What is that called?

[@MapToNowhere911]

Michael Harris I need to know this as well. That came out with the cv axle. 😓

[@protrainz]

OMG, this does NOT work on a 2002 Mountaineer. You CAN NOT get the cv axle shaft out without removing the entire steering knuckle. It'll clear all but about the last half inch, no matter how you position the steering.

[@shannoncoffey4298]

Read my comment earlier in this blog. It is possible to get it out without taking the lower ball joint apart.

[@andrewarrowwood5412]

great video thank you

[@marbrandi83]

What size is the hub nut? All I can hear it is 30 by something? Thanks in advance

[@kubotaman85]

30 MM or 1 1/4 socket. Hope this helps

[@BlkFireHawk427]

30mm
