What tool and size are you using in the axle video? How do you get the bolts out from the inside? I've tried PB blaster and it won't budge.

Here is the video https://youtu.be/Cm3ZCw0_MLo
Do you
have the same problem?

_________________________________

The tools above are related to removing the axle nut. The inner part which is bolted to the transmission most likely uses what is called a triple square spline type tool. It is similar to a torx type bolt, but has more splines,

Now, here are the directions specific to removing the axle.

- Lift vehicle until load on front axle is relieved.
- Loosen 12-point nut.

In the top part of picture 13 there are axle screws or whatever they are called. I can't get them out because they are stuck. Any suggestions on how to get it unstuck?

Most likely, they aren't stuck but just tight. Honestly, I always use an impact gun to remove them. Do you have access to a compressor and impact gun? Is it the triple square bolts?

Yes, it's the triple square bolts. I've already used a impact gun and it just stripped the bolts. I bought a blow torch to see if I can get it loose.

Those bolts have enough head on them that you should be able to get a good pair of vice grips on them. Try that.

We tried that also and they would come loose. I bought a set of bolt extractors and going to try that tomorrow.

One other thought. If you heat them, don't be afraid to tap on them with hopes to break loose any corrosion.

I was never able to get it off. The bolt extractor didn't fit and the voice grips didn't work either. I can't find the right size triple squat or start to fit either.

Welcome back:

Any one that I ever removed was a 10mm triple square. Explain what is happening. Are the bolts already stripped?

I always use extensions and I have a solid swivel extension that I put the triple square on. With the wheel removed, I go right through the inner fender. You will have to keep turning the axle so you can access one of the bolts at a time. I was taught a long time ago to make the tools do the work, so I usually have about two feet in extensions. LOL I also use a snap on 3/8 impact. Everyone laughed at me when I got it, but it is by far the greatest tool I've ever had. It makes jobs so much easier and faster.

I will tell you that it won't remove the axle bolts. I use an air impact to break them loose, then remove them with the electric impact. I attached a picture of what I am referring to.

Try what I suggested.

Let me know if this helps.

I have one a 3/8 as well. I've used many sizes on the triple square and can't seem to find one that will catch. I've used many sizes on the star as well and can't find one that will catch. The T30 is too small and the T40 is too big. M8 is too small and the M10 is too big. Can't find the sizes I need. Not even on the internet.
I have many extensions even the 2 foot one lol. I have a beaker bar as well. T30 use to catch, then it stripped 2 bolts. After that I can't do anything with it.

I know this shouldn't be a torx (star) type bolt, but anything is possible. IF you can wait till tomorrow, I will check my set at work. I know exactly which one I always use because it has much more wear than the other. I swear it is a 10mm. Are you sure the inside of the bolt isn't rusted or have dirt stopping the tool to fit? Also, is there any way you can get a close up picture of them and upload it for me to see?

Let me know,
Joe

I cleaned it out. I can send a picture, but I am waiting on parts to come in. So it will be Wednesday before I can take a picture. It's not a star. That is just the only one I could get to catch.
