Driveshaft hub nut will not come off

[karol_SVK]

Hi, I would like to have a hint how to unbolt the nut in the hub when changing driveshafts.
I need to change them on my dci100, the one on the right side (the longer one) came off without big problems. Thats maybe because I had a bearing change a year ago.
But the left one is not comming loose, no matter what I do. I have put some WD on the bold, left it there for two hours, handbrake on, bricks under the tyres. I take a 30mm keynut...put a huge metal on it, pull...and....I either move the whole car forwards or my front wheel gets spinning
The nut was not removed since it leaved the production lines....so 9 years. I gave it some motivation with a hammer but it did not help.

I am thinking of drilling the nut in two pieces, or should I use some magic nut releaser spray first?

thanks for any tips.

Jack car up, remove wheel.
Then I put a bar in the brake disc vents which locks the disc onto the caliper.

Get someone to hold the brakes on.

If that doesn't work, put a screwdriver in the brake disc vent slots so it anchors against the caliper.

That, or put 2x wheel bolts in, and use a second bar to anchor those against.

Put wheel back on and put it on floor and undo it through centre of wheel.

Weight of car will do more than any bar can to hold.

 

[Mr R.]

Oh and a big snap-on beaker bar

Person in with brakes on then the biggest bar you can get hold of.

Wow, what a quick response, thanks.

Clio was on the ground and I applied as much power with a bar around 1,5meter, till I either spinned the wheel or moved the car.
I will try to lock the brake, but I dont like the idea very much as I know how hard did I pull the bar. Dont like to break things, but there must be a way.

thanks again and good night.

Put it in gear, leave the wheel fully on the ground, put a breaker bar on so you can stand on it or something.

If that doesnt work take it to a garage to get buzzed off.

If non of that works my final resort is always a blow torch...... Get it hot then give it a go

hi again, finally sorted yesterday. After I was able to lock the wheel properly (with someone braking + the screwdriver in disc), I started to brake tools...so finall winner was
