Front axles and rotors.

[BoosTNThreshold]

two issues that I cant solve myself:

1) Passenger side front axle is stuck inside the hub and I cant remove it. I was able to pry it out of the transmission but not the hub. Ive used PB blaster and wd40 and a pry bar and still nothing. Not sure what to do?

2) Front rotors are seized to the hub and cant get them off. At first i checked to see if there were screws holding them in and that was a NO. The previous owner did a conversion to gsx brake setup onthe front. I have also tried pb blaster, wd40, and a small hammer but still nothing. Im kind of afraid to use a larger hammer becuase i dont want to mess anything up.

I went to Lowes lastnight and bought a sledge hammer and some screws to feed through the caliper bolt holes to hopefully put some pressure on the back of the rotor and push it off of the hub. I seen the video on youtube of how to remove rusted rotors on an expedition. If this does not work then Im not sure what else to do?

1) Rent this puller http://www.dsmtuners.com/forums/attachment.php?attachmentid=66514&d=1154592925. It is the "HubPuller model CTA4320 with 1 Inch Screw" and is the heavy duty one used for truck hubs. Anything smaller for car hubs will break (personel experience). Keep calling tool rental places until you find it - ask for by name. Also read this: http://www.dsmtuners.com/forums/new...-wheel-hub-bearing-removal.html#post151512403

2) Scribe/clean where rotor meets hub with a scratch all. Then spray PB Blast or Liquid Wrench there and lightly tap rotor and hub so it will penetrate and wait a couple minutes. If you have rotor push off screw holes use them (see attached image). Otherwise place a 2x4 against inside of rotor and pound it. If that doesn't work use the caliper bolt method (Removing stuck brake rotors) but it may gouge the rotor so you may have to replace or get them turned.

The rotors should come off fairly easy, I just keep tapping around the hub with a hammer to loosen up the rust behind them and they should come right off.

My passenger side came apart very easy like this. I wasnt so lucky on my drivers side though. My drivers side axle was so rusted that you could not see any of the splines, I tryed to clean it off with a wire brush to see things and it almost looked like a welded bead where you should see the splines.

1. try the backwards castle nut trick,
2. heat it try the same way as #1
3. I kept heating it and grabbed our puller, I ended up bending the shaft on the puller(This puller has been used for similar things for years) and I ended up denting the end of my axle
4. I took off the whole assembly as one piece and took it into work to use the press, heated it first, started pressing it... It still didnt want to come out and it was starting to flex the whole assembly.
5. Took an acetlyne torch to the wheel bearing and started cutting it off. (at this point I had ruined the end of the axle)
6.Victory Dance, and I kept the end of my axle as a trophy. Hopefully yours seperates Easy!

Be very careful it is easy to hurt the axle end or castle nut, if it is really stuck in their.

***Finally the rotors are off the car. Sprayed more PB blaster around the hub then let it sit for about 10 min to let it soak in, then blasted the rotors with the sledge hammer, turning it 180 degrees every couple hits.***

The passenger axle doesn't look like its that rusted anymore after I cleaned around the splines with a wire brush. I sprayed lots of PB on it but it still won't budge. Maybe I should just take the whole assembly off and take it somewhere to get it removed.

Good luck with the axle. Sometimes they won't come out regardless of what you do. I've had a few that wouldn't budge with a 20 ton press after getting them glowing red hot.

I've had the screws in the rotor-removal holes strip and I've had rotors suddenly break as I've tightened those screws. The key is to get beyond any fear. Get medieval. You won't damage anything except rotors you plan to discard.

As to the axle in the hub: again, get nasty. Otherwise, you'll have to take the whole package to a shop with a 20+ ton press. Those suckers can get very, very stuck.

My friend Works for Mitsu, He has told me about the tight tolerences with axels and hubs in the cars.

Most of the time if it wont come out they tell the customer to replace the hub and axle.
Hes done a few in a 20 ton press and it still wouldnt budge no matter how much heat.

I've literally broken spindles trying to press them out and beat them out with my 16lb sledge. It would of been great it Mitsubishi would of used anti seize on these from the factory, .
