How to change broken stud on rear axle 1997 ford explorer

I am assuming you are talking about a wheel lug stud. The lug studs are pressed in from the inner side of the drum or rotor or axle flange depending on how your vehicle is equipped. You have to remove the wheel and drum or rotor to get access to the back side. Drive the broken stud out from the front after you have removed the drum or rotor and set the new one in from the back and tap it into the hole until set as the rest are. If you cant get it set all the way you can finish setting it by pulling it into place when you tighten the lug nuts on reassembly. The part should be under $10.00

Things You'll Need:Jack, lug wrench and jack tools Blocks

• Replacement stud
• Vise-grips
• Open end wrench
• Crescent wrench
• Dead blow hammer or heavy mallet

1.    Extra wheel bolts and wheel nuts Impact wrench (if available) or 1/2-inch long handled drive socket wrench 1Buy a new stud. Get the same size stud that's already on the vehicle. Take it off and take it with you when you purchase a new stud if you're not sure of the size.

2.    2Look under the carpeted floor in the cargo area. The jack is behind the rear seat in that area under the floor lid. You need to raise the SUV when you replace the wheel stud for a Ford Explorer. Be sure to block the diagonal wheel before you use the jack.Jack up the SUV and take out some of the brake fluid to avoid overflow. Remove the caliper and rotor. Use support to protect the line rather than letting it dangle. If the rear brakes are drums, take off the drum. You may need to disconnect the emergency brake cable in the rear.Locate an area behind the hub that you gives enough clearance to drive the stud out and allows you to put a new one back in with ease. If there's no way to do it, take off the hub and put it in a vise.Smack the stud with a mallet. Drive the stud out the back. Remove it and replace it with a new one. Push the new stud through until enough threads show to put a wheel bolt on it.

Put a wheel bolt onto the end of the stud that comes out of the opening toward you. Make sure the slanted edges face you. Tighten these down and, as you do, notice how they pull the stud through the hole. Keep tightening and adding more bolts until the stud seats flat against the hub in the back.Take off the bolts and put all the parts back on in reverse order that you took off to replace the stud on your Ford Explorer. Make sure you add more brake fluid and bleed the brakes before you finish.
