SOURCE: can not remove rear axle on chevy avalanche 4x4 1500.

you will need to take off the differential cover (drain and change diff oil at this time)

rotate the axle so that you can get at the cross pin and remove it by undoing a small bolt that holds it in place. it should slide out with ease, but i have had them stick, take care not to let the cross pin get lodged where it is difficult to extract

a single C-clip is holding each axle inside the differential housing

you will need to push in from the outer end of the axle, while simultaneously manipulating the C-clip off of the inner axle, repeat this same process on the other side

i will put some of pics up in a minute

SOURCE: 2002 Avalanche gas gauge problems

Gm has a real problem with fuel tank sending units. That is what is wrong. You need a fuel tank sending unit. You can only get them aftermarket with the whole fuel pump module, but you can buy them seperate if you buy it from the dealer.

SOURCE: how do you change the rear brake pads on a 2002

You need to remove the 2 bolts that attach the caliper to the mounting bracket (big metal) with an 18mm socket, use a 1/2" drive ratchet to give you some torque. If you are removing the other bolts that just "turn" you are on the wrong bolts, these are the bolts that allow the caliper to slide in and out freely. you should be able to then use a ligth hammer to tap the entire assemble off of the rotor. then replace you pads and rotors if needed. also your parking brake is located inside the drum of the rear rotor. Making adjustments to these can be quite a process but can be done in the driveway. good luck.

SOURCE: 2002 Chevy Avalanche. Truck will not

Do a bench test on the starter. Remove starter, hook up a ground cable to starter, and positive to two prongs on starter and it should spin. You can do this in vechile too but not suggested due to risk of injury. If it doesn't spin, probally a solenoid or the starter it self. Unlikely but possible.

Minimum rotor thickness

I don't know the min thickness, but I have an outback just like yours and if there is a problem with uneven rotors it's usually cheaper and easier to buy aftermarket at NAPA auto or other supplier (shop around) and trash the old rotors. If the rotors can be turned then keep them for the next brake job and use them then. Outbacks are easy to do about 30 min a side rotor and pads after the wheel is off, just did mine.

Minimum rotor thickness

ON most disc rotors the minimum thickness is cast into the body of the rotor and will read min thickness and a dimension. The dimension is also available in the workshop manuals and from the service department of your vehicle. Do not be surprised if you find that your dimensions are almost at do not machine limits as original rotors are not much thicker than the low limit.

Do you have to take the hub off on a brake job for a avalanche 2003 4 wheel drive

To do a brake job front or rear there is no need to remove the "hubs" the front and rear rotors or rear drums are knock offs. if they are stuck to the hub a couple of gentle hits with a hammer will usually free them up. If you are replacing the rotors than whack away as hard as you would like.

How do you remove the rear rotors on a chevy avalanche 4x4 the rotor is stuck and won't come off.Is there a trick to it? I've tried hammer and prying it.

Well with the rotors on the rear you still have a drum with brake shoes in the middle for your E-Brake.Think you have to back off the parking brake nut at the equalizer(one cable into two) to get slack in the cable to back off the shoes inside.Well hope this helped and good luck.

Abs Is engaging irratically on 2002 avalanche

Did you bleed the system after doing the brakes? and since you din't say abs light I assume you mean the brakes are acting erratically. If you bleed the breaks first after that try it and if it still does it make sure you have the correct rotors and pads.

I am trying to replace my rear rotors/pads.size of rotors/pads?

Take a tape measure and measure acroos the middle of the rotor, but it should tell you on the rotor what size it is. if push comes to shove take one to the parts store and match it up.
