Re: rear end looks jacked up
I assume you do not have air suspension. Check to see if rear suspension is too bouncy. just force the rear down with all your weight and watch it bounce. if it is too loose, the a shock may have broken allowing the vehicle to release to a fully sprung position. keep me posted.

i had this problem with BMX X5. the rear end was down and the fuse was ok. I jacked her up at the back so that both sides are equally up, started and let idle while it was still on the jack. i switched it off and let it down and the rear end went up. I think I accidentally reset the air suspension system.
you need to jack up car until both rear tires clear ground.use two jack standsand place them on the subframe. on most gm (olds) i jack the car up right in the middle of rear crossmember. set jack stands ,when letting down car MARE SURE CARS WIEGHT IS BEING SUPORTED 95% ON STANDS.let jack down.make surecar is stable i give it a shake. don't remove jack.you need to jack up rear crossmember 3 to 4 in. it takes the wieght off old shocks.Therev are two diff.style shocks gm used #1 shock had holes in both ends of it.#2hole in bottom and threaded shank on top. its pretty strait forward with #1 style shock make sure you use all new hardware that came with shock. #2 style can be tough somtimes, i let tension ( some )off jack be cause i use a air impack to remove upper nut on shock but if you don't have air tools, at tip of shock you will notice a 2 flat sided tip use a 1/4 in wrench to hold top from turning while using 1/2 in wrench for nut removal also on this style shock tighten down just till rubber squeezes 1/8 in past washer. if tou over tighten on upper style #2 shock it will split new rubber washers.#1 style can be tighten till stops. hope this info is what you needed.

Check the vehicle height sensor located at the rear trailing axle. It looks like a rod with 2 ball studs on both ends, this vehicle has air ride suspension, an air compressor operates as soon as the key is on, it gets feedback from the level sensor indicating the vehicle height via the height sensor, if it is disconnected, hanging down it thinks the vehicle is sitting low and keeps pumping air into the shocks until it sees a feedback from the sensor, it will eventually stop at its max travel.
Look under the car - you'll see 2 long metal rails ( the frame rails) . Support each side with a 2 ton minimum jack stand fully extended approximately one foot ( 12" ) in front of the rear wheels. Now use your jack ( preferably floor style ) to lift one of the rear wheels to relieve the pressure on the shock. Remove fasteners securing the shock, then remove and replace the shock. If the new shock has a plastic strap attached, do not cut this strap until you have mounted the shock on the vehicle. If you do not have an exposed frame rail, you'll see a "pad" in front of the rear wheel close to the outside of the car - it should be about 10 inches in from the pinch weld and about 12 inches in front of the wheel. Use this pad for the stand and lift the vehicle by the c shaped bar that goes from 1 rear wheel to the other. Do not support the car with just the jack -it could let loose and drop the car on you. Hope this helps!
Ok first off if the vehicle is equipped with air ride you need to turn the air ride off or you will blow out the rear bags when the rear is off the ground.
For the front Remove the wheel. Take off the upper shock nut. Now remover the two lower retaining nuts. Compress the shock and pull it out. Install in reverse order. Before installing the new shock push the piston completely down and allow it to return. Do this 2 to 3 times.
For the rear remove the wheel support the rear end with jack stands at the jack points. Now use your jack (not a scissor jack) and place it under the rear diff to support the rear diff. If you have another set of jack stands use them and support the rear axle as it sits.
Remove the lower shock bolt. Now remove the two upper shock bolts and the shock will come right out.
Take skirting down in trunk on the side you are working on. Remove center nut on shock 15MM. Then jack that side up or whole rear of car and place jack stand or jack under control arm. Now you can remove the two 10MM bolts that fasten the bottom of the shock to the control arm, most of the time the speed nuts brake but you can hold on to them with a pair of pliers. Once this is done remove the shock place all hardware on shock and install. The new shock will come with an 18MM center nut. Hope this helps.
there are 2 ways of fixing that problem you can replace whats broken which is more than likely the air bags, which is expensive, or you can get an aftermarket set up with regular springs and do away with the air bag system completely it's not hard to convert it over just unplug the compressor jack up the car to lift the weight off of the suspension put a jack under the rear end housing and loosen the the shocks and lower the rearend housing remove the air bags put springs in their place jack up the rear end bolt shocks back up and your done.

Remove or disconnect the following:
Electronic Ride Control (ELC) air tube from the shockTwo bolts securing the shock to the control armTrunk trim to gain access to the shock upper mounting nuts.Cover, the two nuts, and the reinforcement from the top of the shockShock from the vehicle

To install: Install or connect the following:
Shock, reinforcement, and the two nuts. Tighten the mounting nuts to 15 ft. lbs. (20 Nm).Shock coverTrunk trimShock-to-control arm bolts and tighten the bolts to 18 ft. lbs. (24 Nm)ELC air tube to the shock.Tire and wheel assembly
you could replace the one shock but do you know why it is leaking oil? Typically unless there was something traumatic to happen to one of the rear shocks, then if one is going you can almost be the other one will go soon. I ended up having too many problems with the air ride suspensions. If you haven't yet, look into conversion kits as something to consider for down the road if nothing else. www.strutmasters.com has a great kit that is made in America and comes with a lifetime warranty.
