Where do i place the floor jack if the safety stands are going to be supporting by the frame

You're talking about the engine cradle? Install an engine/transmission support. Raise the vehicle and put it on jack stands. Locate a floor jack under the sub frame. Disconnect the engine mount and transmission mount bolts. Then lower the sub frame.

jack up car, fit safety jacks at each side of frame well in front of rear wheels, remove tail shaft , place floor jack under rear axle housing and jack up , but not lifting off safety jacks.remove brake lines, remove rear shocks, remove drag links ect from chassis frame, lower and remove jack, wheel out rear axle.

The intent of a jack stand is to provide safe solid support for the vehicle while you are performing work on it. Going under a supported vehicle at any time can be dangerous.
- I was taught to place jack stands under a frame or unibody support point, and NEVER under a suspension component that could move independently from the frame.
- Block wheels that are in contact with the ground to prevent the vehicle from moving forwards or backwards.
THE PARKING BRAKE OR GEARSHIFT "P" ARE NOT ADEQUATE.
- LOWER THE VEHICLE SO THAT ITS WEIGHT IS GRADUALLY APPLIED TO THE JACK STAND.
- WITH THE JACK STILL IN PLACE, GENTLY NUDGE THE VEHICLE TO MAKE SURE THAT THE JACK STAND IS SECURELY HOLDING THE WEIGHT.
- When using jack stands, the vehicle should be on a level surface, and evenly supported by jack stands of the appropriate size for the load being supported.

place the trolley jack under the front cross member . (The big bit that connects the side frames under the sump). Lift as high as possible and place the jack stands under the chassis ( moulded rails ) where the sub-frame meets . Then place the trolley jack under the rear diff and lift as high as possible Place the jack stands under the chassis at the front of the springs or track rods By using these positions you will have the cabin securely jacked up with all the wheels free to remove or to work on. Before going under try rocking the vehicle hard to ensure that it will not move off the stands.

lower ball joint, behind wheel

youll need to purchace what i call is a balljoint remover ( pickel fork )you many want to purchase both sizes. Having also a assortment of wrenches, a floor jack to set under the lower A arm and jack it up a bit. all this once the tire and rim have been removed. Because you are seperating the front spindel that holds the tire on from the upper A arm the floor jack is nessary. you may also put a jack stand under the framing of your El Camino to support that paticular side of your El Caminos front frame. once the jack stand and floor jack are placed properly your tire and rim can come off. You can see the that there is a nut with a cotter key on it. you remove the cotter key then the nut , after that you may remove or seperate the upper part of the spindle from your A arm. The coil spring is going to pop the A arm up and relieve the tension of the spring. Once that is completed remove the back side of the A arm which you can see, that it is secured on both sides. You'll figure the rest out once you tear into it.Hope this was helpful. as for instillation of the new one reverse what you did, by the way the coil spring will have to be compressed.

Hope this helps and please don't forget to rate...thanks!

Jacking points on all Jeep vehicles

Your Jeep was supplied with a jack for emergency road repairs. This jack is fine for changing a flat tire or other short-term procedures not requiring you to go beneath the vehicle. Do not attempt to use the jack on any portions of the vehicle other than specified by the vehicle manufacturer. Always block the diagonally opposite wheel when using a jack.

Placing a floor jack under the front frame rail

Placing a floor jack under the rear frame rail at the leaf spring shackle. It may be necessary to place a block of wood between the frame rail and the jack

Supporting the front of the vehicle with jack stands placed under each frame rail

A more convenient way of jacking is the use of a garage or floor jack. You may use the floor jack at the specified points in following the illustrations.

Never place the jack under the radiator, engine or transmission components. Severe and expensive damage will result when the jack is raised. Additionally, never jack under the floorpan or bodywork; the metal will deform

Support the rear of the vehicle using jack stands placed underneath each side of the rear differential (inset photo)

How to Replace Wheel Lug Nuts
(DIY Complexity: Easy / Time: 1.5 hours)

Parts:
1. Lug Nut


Tools:
1. Floor Jack
2. Jack Stand Set
3. Ball Peen Hammer
4. Tire Iron
5. Socket Set


Steps:
Step 1 Secure the vehicle on a solid level surface to ensure that it does not roll or lean when raised.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.

Step 2 Break the lug nuts loose but do not remove. Using a floor jack, raise up the front of the vehicle.
o Tip: Using an aftermarket floor jack, instead of the original equipment (OE) jack, can make the job easier and safer. Verify the condition of the floor jack before use.

Step 3 Secure the vehicle with jack stands on both sides for safety before starting any work. Do not rely on the jack to hold the vehicle up while working.
o Tip: The pinch welds or the frame rails are the two best locations for vehicle support.

Step 4 Remove the lugs nuts. Inspect the threads on the wheel studs.

Step 5 Install the new lug nuts by hand making sure they thread properly.

Step 6 Tighten each lug nut in a star pattern. Lower the vehicle to the ground and torque the lug nuts to the manufacturer’s specifications.
o Tip: Refer to the owner's manual for the exact location on the vehicle.

Step 7 Road test the vehicle to verify lug nut repair.


I really hope help with this (remember comment and rated this post).

Before any service is performed, carefully check the following:

• Be sure the vehicle is properly centered and secured on stands or a hoist.
• If the vehicle has antilock brakes, depressurize the system according to the procedures given in the service manual.
• Disconnect the battery ground cable.
• Front brake pad replacement begins with removing brake fluid from the master cylinder reservoir. If this is not done, the fluid could overflow and spill when the pistons are forced back into the caliper bore, possibly damaging the painted surfaces.
• Replace the cover.
• Discard old brake fluid.

• Raise the car. Make sure it is safely positioned on the lift.
• If you don't have a lift, use a jack and jack stands.
• A handle on the jack is moved up and down to raise part of a vehicle and a valve is turned to release the hydraulic pressure in the jack to lower the part. At the end of the jack is a lifting pad.
• The pad must be positioned under an area of the vehicle's frame or at one of the manufacturer's recommended lift points.
• Never place the pad under the floorpan or under steering and suspension components, because they can easily be damaged by the weight of the vehicle.
• Always position the jack so that the wheels of the vehicle can roll as the vehicle is being raised.
• Never use a lift or jack to move something heavier than it is designed for. Always check the rating before using a lift or jack. If a jack is rated for 2 tons, do not attempt to use it for a job that requires a 5-ton jack. It is dangerous for you and the vehicle.
• Safety stands, also called jack stands, are supports of various heights that sit on the floor. They are placed under a sturdy chassis member, such as the frame or axle housing, to support the vehicle.
• Once the safety stands are in position, the hydraulic pressure in the jack should be slowly released until the weight of the vehicle is on the stands. Like jacks, jack stands also have a capacity rating. Always use the correct rating of jack stand.
• Never move under a vehicle when it is supported by only a hydraulic jack. Rest the vehicle on the safety stands before moving under the vehicle.
• The jack should be removed after the jack stands are set in place.
• This eliminates a hazard, such as a jack handle sticking out into a walkway. A jack handle that is bumped or kicked can cause a tripping accident or cause the vehicle to fall.
• If you use support stands on asphalt, put a piece of thick plywood or a steel plate under the stands.
• Remove its wheel assemblies.

• Inspect the brake assembly.
• Look for signs of fluid leaks, broken or cracked lines, or a damaged break rotor. If a problem is found, correct it before installing the new brake pads.

• Loosen the bolts and remove the pad locator pins.
• During servicing, grease, oil, brake fluid, or any other foreign material must be kept off the brake linings, caliper, surfaces of the disc, and external surfaces of the hub. Handle the brake disc and caliper in such a way as to avoid deformation of the disc and nicking or scratching of the brake linings.
  
  
  
• Lift and rotate the caliper assembly from the rotor.

• Remove the brake pads from the caliper assembly.

• Fasten a piece of wire to the car's frame and support the caliper with the wire.
• When a hydraulic hose is disconnected, plug it to prevent any foreign material from entering.

• Check the condition of the locating pin insulators and sleeves.

• Place a piece of wood over the caliper's piston and install a C-clamp over the wood and caliper.
• Tighten the clamp to force the piston back into its bore.
