    It is dragging on the ground. I can't just leave it be.

    That's connected to the rear axle? Do you know where I can find a diagram of the rear axle stuff? I'm a woman on a shoestring budget...can't afford a mechanic if I can figure it out myself.

This hose is connected to the brake lines and it is capped on the end, if is loose then a clip fell off that holds it in place at the top of the shock absorber frame. This hose really has no function as far as I can tell you can cut it to about 4 inches and cap the end so that nothing goes in or comes out.

It's probably the breather for the rear differential. Leave it be.

    Ok,that's not the breather hose. It's probably an emissions hose,like the gas tank to charcoal canister line. Better get the truck on a lift & take a gander.

When I start the car it runs fine but when i put it into gear it dies and i have to restart the car. Right before this when I applied the brakes the car would jump ahead instead of stopping.

Sounds like you may have a vacuum leak. You need to look closely around the carb/intake area for any disconnected small rubber hoses. Also check a fat rubber hose (1 inch or so) which goes to the big drum looking thing drivers side firewall - part of the brakes power booster system.

Look for hanging loose tubes/hose or worn through by rubbing etc.. Try to replace tubes to closest point where it looks like it goes. May have to cut a small peice off the end if it's stretched out and loose fitting.
Hope this helps

It is a vent for the rear end and should fasten to the box or a frame crossmember. Fasten it as high as you can reasonably get it because while it lets air in it can also let water in. Hope this helps.

My 2003 Olds Shilouette air shocks work but the sensor for the load must be out. With a load the air compressor is not signaled to pump. The pump works when I activate the auxillary button. Where is that...

the load sensor is probably broken. It connects the rear axle to the frame to measure load. Its mounted on the left side of the rear axle. Its commonfor these to become damaged if the vehicle is lifted by the frame rather than by the axle. Looking at the part you will probably see the sensor arm hanging loose.

Rear Axle Axle Housing Assembly Removal & Installation To Remove:
Exploded view of the rear axle mounting 88457g85.gif

  1. Raise and support the rear of the vehicle safely using jackstands under the frame. Position a floor jack or a second set of jackstands to support the rear axle housing. If a floor jack is being used, take care when removing the U-bolts to keep the axle from suddenly dislodging.
  2. Remove the rear wheels and drums for clearance and to remove some weight from the axle housing.
  3. If equipped, remove the axle vibration dampener.
  4. Matchmark and remove the rear driveshaft from the pinion flange. Either remove the shaft completely from the vehicle or support it aside from the undercarriage using safety wire, but DO NOT allow the shaft to hang from the slip joint.
  5. Remove the shock absorber-to-axle housing retainers, then swing the shock absorbers away from the axle housing.
  6. Disconnect the brake lines from the axle housing clips and the backing plates (wheel cylinders). NOTE: When disconnecting the brake lines from the wheel cylinders, immediately plug or cap the lines to prevent system contamination or excessive fluid loss.
  7. If applicable, unplug the speed sensor connectors at the junction block.
  8. Disconnect the parking brake cable(s).
  9. Disconnect the axle housing-to-spring U-bolt nuts, washers. U-bolts and the anchor plates.
  10. Remove the vent hose from the top of the axle housing.
  11. Remove the axle with the help of an assistant by moving it to clear the leaf spring, or if desired, the leaf springs can be disconnected from the frame at the rear end to lower the axle down and back, but first refer to the leaf spring procedures for information regarding spring installation and removal.
To Install:
  1. With the help of an assistant, carefully position the rear axle into the vehicle.
  2. Connect the vent hose to the axle housing.
  3. Be sure the housing is properly positioned on the leaf spring, then loosely install the U-bolts, anchor plates, washers and nuts.
    • Tighten the U-bolt nuts in a cross pattern to 18 ft. lbs. (25 Nm) to make sure everything is evenly seated. Then tighten the nuts in steps to 41 ft. lbs. (55 Nm) on 1994-95 models or 74 ft. lbs. (100 Nm) on 1996 and later models.
  4. Remove the caps from the brakes lines then connect the lines and secure them to the axle housing.
  5. If removed, connect the parking brake cable(s).
  6. If applicable, attach the speed sensor connectors to the junction block.
  7. Align and install the driveshaft assembly. Refer to the procedure earlier in this section for details.
  8. Install the shock absorbers to the lower mounts, then tighten the mount nuts.
  9. If equipped, install the axle vibration dampener.
  10. Install the brake drums and the tire/wheel assemblies.
  11. Properly refill the brake master cylinder and bleed the hydraulic brake system.
  12. Check the fluid level in the rear axle assembly and add, as necessary. Make sure the vehicle is level when checking and adding fluid.
  13. Remove the jackstands and carefully lower the truck.

Asking which kind of brake in back rear driver makes a lot a nois

You have brake rotors and pads on the front. Looking on the rear axle if it looks like the front it will be rear rotor and pads. And if you cannot see the rotor or pads on the rear axle then you will have what is called rear drums and brake shoes. Hope this will help you.

How do i take a rear rotor off 2004 jeep cherokee

Remove the caliper slide bolts and take the caliper loose and hang caliper with a wire to something. Don't let the weight of the caliper to be supported by the brake hose.

Next, remove and discard the O-ring securing the rotor to the axle studs, and remove the rotor. Hope this helped and good luck.

Rear brake isn't working

How did you check the rear brakes not working? If the van is raised and the wheel hanging, the load sensing proprotioning valve releases the pressure on the brake line and you might not be geting lots of braking on the rear axle. Is that the case? You might need to put axle stands under the suspension arms at the back and put some load in the van and brake see if there is any difference now. Cheers.

I have a Jeep Wrangler 1992. Replaced rear axle with a Ford 8.8 axel rear end and installed all new brake rotors, callipers, hoses, metal lines, forward brake discs, hoses. Have bled reapeatedly....pumping...

The proportioning valve most definately can be the problem. Did you change it or is it the original? (A disc/drum system uses a 70%front/30%rear braking ratio, whereas an all-disc system is alot more even). I would first bleed the master cylinder. Then I would 'gravity bleed' the rest of the system by opening the bleeders on all 4 wheels. Do not at any point let the m/cylinder go dry. Also, do not touch the brake pedal.
Continuously check all 4 bleeders, when clean brake fluid with no bubbles at all is running from a bleeder, close it. When all 4 wheels are done, recheck the fluid level and you should be OK.
Pump the pedal to 'self-adjust' the rear calipers, then re-check the fluid level.
Any problem after that means you either have a loose connection (it's possible for a tiny leak to let air in, but not let fluid leak), a leak, or you need a new (disc/disc type) proportioning valve. I would try Summit Racing myself. Good Luck!
