Very rough power steering left problem also causes front/end to go way up/air shocks to fill 100%. Turning right from left and going to center; front end/air shocks go back down to normal height.
1998 Cadillac Seville SLS V8 Front Wheel Drive Automatic 70,000 miles
In park, reverse, and taking off, when turning the steering wheel to the left causes the front/end/air shocks to fill al the way up with the whole front end going way up, or jumping up off the ground on acceleration. With alot of racket and crunching sounds too.
In park with the tires straight forward, if you turn the steering wheel to the left their is major resistence at 45% and you have to force the steering wheel with a crunching and grinding noise, to get past this resisatence and be able to turn the steering wheel all the way to the left.
If you back up and turn the steering wheel to the left the same thing happens, but as you then go forward and take off the car jumps and sounds like it's stalling and then lurches forward with alot of noise, rattling, and shaking.
In park as you turn the steering wheel back to the center with the wheels going straight or to the right, the shocks let out the extra air, and the front end goes down to normal.
Message display: speed limited to 90 mph
The car is not driven much. The problem started around 2 weeks ago. 1 week ago the message display started to say: speed limited to 90 mph.
So far no other messages like this are on the display while the car is running.
Also the whining noise and racket from the power steering pump or belt seems to be alot louder when turning all the way to the left, than even the usual loud sound some cars have, when turning the steering wheel all the way to the right or left.
Once you get going and go straight the symptoms subside are not that noticeable and the engine power is full.
The power steering pump seems to be ok, but I'm not sure, and it is filled, but the fluid might be too hot.
Which part of the power steering systen, assembly, steering gear, pump, etc is loose, needs adjusting, is worn, malfunctioning, needs replacing?
Why is is the power steering problem causing the front/end/air shocks to fill all the way up with air?
Is the pcm sensing rough road conditions because of the very rough running power steering system and adding lots of air in response?
I ran a scan tool and all 8 readiness tests are checked and there is only 1 code: P0103 mass airflow.
I need a reply by tues morning because this car which is not my car but I have an interest in and I drive it alot, is going to a repair shop that a friend (who has nothing to say about cars) of the owner uses. All they can say about the mechanic is that he's ok and that's it.
But we've never spoke with that mechanic before. We are very low on $ and I realize that this can be a moderate $ or costly $ repair and want to have as many facts about what's wrong with this car.
Before getting an estimate and/or the owner just letting them go ahead and fix it without us being sure that that the estimate and repairs are only what was needed ro be repaired.
I can read diagrams, can work on cars, have alot of tools but no place to to really work on a car.
I have done lots of work on my 76 and 77 plymouth v8 318 cars that I used to own.
So I can handle a full review of this question and use it to do alot better when dealing with this new mechanic that we have never even spoke to yet.
I said to the owner of the car that this repair can cost any where from $300-$500 if it's just a loose part or adjustments are needed.
Or $500-$1500 if it's just a part or parts that need to be replaced.
Or up to $2500 if the whole steering system needs replacing and for other related repairs.
The owner of the car said to me not too happily because she can't afford to pay more than $700 max,
" Well, we have no choice but to just trust this new mechanic that we've never met before, because I need my car fixed right away. I don't have a regular mechanic to go to who has worked on my car and also can handle this kind of involved repair".
" So whatever this new mechaniic says and does, it's up to him. I need my car fixed and I can't tell if his diagnosis and estimate is correct, and the repairs that he'll be doing is just what needed to be done".
" Or if he not on purpose went and did more than what was needed, or if he went and did more than what was needed to get a better profit for his time".
I said to " get an itemized estimate first, don't just tell them to go ahead and fix it because they may do a bigger job when only a lesser repair is needed, and that I could do a good job of oking or not oking his estimate".
We're having money problems now and can't afford to pay alot more than is needed.
I'm adding on some more to my donation now, I wish I could give you more. I'm sure that the advice you'll give me is worth 10x or more.
