    Why does my car make a clunking sound back right when I turn right, also the back end of the car seems higher
    I have not had any work done on this. I have 73000 miles on it. I just noticed it today. No warning lights on.

      Maybe a problem with air suspension if equipped with this. Especially if car is higher than norm. It might indicate a bad height sensor that is broken and banging on other stuff.

      A collapsed or clogged power steering hose can cause this condition. Typically, both of the steering hoses (pressure and return) are replaced at the same time the rack and pinion unit is replaced - keeps the syetem cleanliness and integrity.
      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the power steering pressure hose from around $12.70, and the return steering hose from around $31.00 for your vehicle.

      This is the most common failure of a GM PS pump. The shaft breaks in two pieces inside the pump. Buy a remanufactured pump. There is no other alternative unless you buy a used pump which is fine.

    I have a steering wheel that is coming away from dash. No turn signals no horn no cruise control
    111,000 approx. miles. The fan to the heater also seems to not want to work on occasion as well as the radio. This just started the last couple weeks I took the car in to my mechanic for the steering wheel, he said there was nothing he could do. I have not yet ...

      Did the entire steering column fall out or is the tilt wheel just very loose and flopping around. You could get an entire steering column from a salvage yard for pretty cheap and it is not hard to replace. If it is just a loose tilt steering mechanism that can be fixed by taking apart the column and tightening or replacing the screws that fell out. It is quite common on these cars for the screws inside the column to loosen over time. As for the heat problem. Sounds like you may need a new blower motor. If the steering column is falling down it may be pinching other wires. Any pinched or broken wires could be causing your electrical issues. The wiring for all the steering wheel controls run thru the column together on the combination switch(turn signal switch) and can easily be damaged by loose column.

      Yeah I guess we both have had a few of these GM tilt columns to fix over the years with the 4 loose screws that you can only access 3 of unless you disassemble further to get to the 4th.

      Since you have said twice that the "key will not go into the ignition" I am understanding this as that your key will not enter the hole at all or not far enough in and consequently the key of course would then not be able to turn as a result of that. If this is correct, then your fix here would be replacing the ignition lock cylinder which would typically not be a DIY type repair and before replacing the lock cylinder the lock tumblers have to be coded to match your existing key. It is not an impossible job for a non mechanic but requires a step by step procedure with pictures or even a YouTube video for a non mechanic to get through this repair. It requires removing the steering wheel as well. To have a shop do this job expect a bill of $400 around.

    My car shimmies at speeds of 25 and 45. Not always consistant.
    Car shakes at speeds around 25 and 45. Not bad at other speeds. And it isn't always constant... Sometimes it really sakes and other times it's not that noticeable. Today, the steering wheel rocked at 20-25 mph but not at other speeds. I've had the tires ...

      Replace the front drive axles. One of the inner tripode housings is worn internally and the tripode joint that is supposed to slide in and out is becoming locked in place in one spot and then the axle becomes like a solid steel bar and pushes on the tire and shakes the car and steering wheel. There can also be a broken motor mount accompanying this bad axle condition. Everyone always misses this one. I did too the first time I came upon it..

    Horn goes off by itself
    Hi. My horn has been "wonky" for a while, going off when I just brush on top of the center of the steering wheel. Have to smack the steering wheel a few times to make it stop. Today it started going off totally by itself when no one was in it or near it. I pulled ...

    How do you change the rear spring?
    The fiberglass spring that runs from side to side on the rear end is splitting due to the bushing wearing itself away. The bushings are completely gone and now I need to replace the whole spring and all. How do I do this??

      Try turn your steering wheel back and forth, it is possible that you steering wheel lock is applying pressure that's why you can't turn the key.

      Usually this requires the replacement of the ignition cylinder.

      A broken or out of adjustment steering wheel lock can cause this kind of trouble.

      SOME VEHICLES ALSO HAVE A LOCK ON THE BRAKE PETAL, TRY TO INSERT THE KEY, TURN THE STEERING WHEEL IN BOTH DIRECTIONS IF IT IN LOCK POSITION. THIS MAY REQUIRE A GOOD HARD PULL! PLACE YOUR FOOT ON THE BRAKE AND TRY TO ENGAGE THE TRANSMISSION GEARS, PUSH THE LEVER FORWARD AS WELL AS BACKWARD AS MUCH AS YOU CAN. TRY THE STEERING WHEEL AGAIN. IF THIS FAILS THEN YOU PROBABLY HAVE A BAD KEY SWITCH. IT WOULD BE TIME TO CONSULT YOUR CAR SERVICE PERSON.

    Repaired leaking high pressure ps line...now it is very hard to turn...is there a special bleeding procedure?
    Before I repaired the line it was leaking pretty good but worked fine as long as I kept fluid level up. I cut the line at the leak and spliced it with HP line and double clamped on each side. Metal line is pushed together so there is no cavitation issues at repair ...

      There is no magic here to bleed it. if you have a lack of power steering assist there is an almost 100% probability here that the PS pump is junk, even if you say it was OK before while it was leaking. Only thing that could change this situation is if the repair you did somehow restricted the diameter of the hose right where you fixed it, and if that were the case then replacing the line would solve it. Bleeding takes place just by going lock to lock a few times and your done. One last thought...try unplugging the EVO (electronic variable orifice) power steering valve that is attached to the pump where the hi-pressure hose attaches. This valve reduces steering oil flow to increase "road feel" at higher miles per hour and if it fails you can have a lack of assist. I have never seen one fail though.

      Check out the rear suspension arms. Worn bushings loose tie rod end or bent arms can cause this. The rear suspension arms are pretty weak and often get bent. Check for bent or worn out arms then do 4 wheel alignment. Also check for broken rear coil spring. These rear coils will sometimes break the bottom coil it is hard to tell so compare both sides. Make sure air shocks actually work and are filled with air.
