What size is the front axel nut on a 97 neon

Jack the vehicle up at proper jack points and lower onto jack stand or stands.remove drivers side wheel. Use needle node pliers and a screwdriver to remove the cotter pin in the axel nut and determine the size of the axel nut. It will most likely be metric 28mm to 36mm. Use an impact to remove the axel nut. Now you will need to remove one or both of the ball joints. Start with the bottom one first and hold the axel in place and pull out on the hub. After you have the hub off of the axel note the splines and how the line up. Now turn the hub so that it is out of the way. You may be able to just yank the axel out of the transmission. If it didn't come out easily you will need a crow bar to gently pry the axel out of the case. Be careful not to put too much pressure on the transmission case. It's aluminum and it will crack and break if you beat on it. Just pry gently and with the transmission in neutral ( be sure to chalk the rear wheels so the car won't run you over) slowly rotate the axel and pry until it comes out. If that doesn't work you will need to rent a slide hammer. Thread it to the free end of the axel and forcefully slide the weight out to knock the axel about of the trans. Installation is reverse. DO NOT USE A HAMMER to force the axel back in you will mushroom the threads and never get the nut on.

Remove the wheel and the lower ball joint from the spindle. It will also make it easier if you remove the tie rod end. There is a large hut at the tire end of the axel. Remove that nut and washer. Take a rubber or brass Hammer and hit the end of the axel to push it through the bearing assembly. If it is really stuck, put the nut back on so that the nut is even with the end of the axel and uses a heavier hamer to break it loose. Once you break it loose, pull back on the rotor while pushing the axel to remove it from the hole it passes through. (Becarefull with the brake hose. If it is pulling too tight it might be best to remove the caliper and use a hanger to suspend it until you are done.) You will need a really BIG screw driver or a pry bar. Put the pry bar between the case and the hub of the axel and push in quickly and firmly to pop it out of the trans axel. It might take a few tries. If it resists look for a ridge and put a big screw drive on the ridge and use a hammer to pop it out.

Once it is out, reverse directions. Do not use the hammer on the new axel any where.put the end into the trans axel as far as it will go and then put the other end through the wheel bearing. Use the leverage you have with the rotor and bearing side to push the axel into the trans. You should hear it snap into place. Before you put the ball joint back on go to the trans axel side and use that pry bar and gently try to remove. if it resists it is seated, if it slides out, you need to seat it again. ONce you are sure it is firmly seated back into the trans, you can bump the ball joint and tie rod back together.

Good luck and be careful

There's not any special tools. You need a socket to fit the nut on the end of the axle and a wrench to take the nut and bolt off the bottom ball joint that slides through the control arm. Take a bar, pry down on lower control arm, pulling ball joint out, then pull the upper part out by hand, away from the car, slide axle out of the bearing assembly. Take a pry bar, put between trans and axle, give it a swift, quick ****. The axle should come out. Remember to always put jack stands under the car and be safe. Phil
