The only time you really need to turn your wheels when parked is when parking on a hill. Uphill you should point your wheels away from the curb. When pointing downhill you should point your wheels towards the curb. This is so if the parking mechanism should fail, the curb will hopefully stop the momentum of the vehicle and keep it from rolling very far. ...

The vehicle in question is a front-wheel drive. FWDs are sensitive to front wheel alignment, since the front suspension and wheel linkages work under different conditions when accelerating and not accelerating: on acceleration, the wheels push backwards on the road, thus tend to move the front suspension forwards relative to the vehicle. on de-acceleration,...

Note: this answer only addresses drive-by-wire; I don't know if you could tell whether the other systems employ by-wire technologies as readily. Drive-By-Wire : Look at your throttle body If it has a throttle plate actuated by cable, you have drive-by-cable, not drive-by-wire Drive-by-cable examples: Drive-by-wire examples: Notice the absence of a ...

Drive by wire systems have no mechanical connection between the input decive (like a throttle/gas pedal) and the output device (like the engine). They use only electrical signals. To my knowledge there aren't any cars that use this system for steering. Your steering wheel is mechanically connected to the front wheels but is assisted by an electric motor. ...

Found it was because a bolt holding the steering rack in place had sheared. Very dangerous and glad I decided to visit a mechanic!

You seem to be describing the weight of the steering, which varies from vehicle to vehicle. It isn't something to be concerned about. Many factors influence the lightness (or heaviness) of steering feel, including: steering/chassis geometry amount of hydraulic (power-steering) assist tire size I would be concerned if you cannot or struggle to turn ...

When you say OBD i'm assuming you mean generic data. The answer is outright NO. OBD generic data has no parameters that the alignment can be gleamed from. If the car has a steering wheel angle sensor then maybe you could tell if something is wrong. This data would be available in manufacturer specific. If the angle has been off for a long time at high ...

The force required for the driver to turn the steering wheel would be a torque measured in foot-pounds (or Newton-meters). Extra Credit: The actual force required for the rack in a rack and pinion style steering system to push/pull the tie-rods to turn the wheels would be a simple load measured in pounds or kilograms. The actual load the tires experience ...

I would venture to guess that it is a completely random, and in no way threatening plastic trim piece/wiring harness/adjustment lever under the steering column that is rubbing or vibrating against it's fasteners or another trim piece. It is completely intermittent because sometimes it catches itself in such a way that it doesn't vibrate, or it could be ...

tl;dr: Winter tires are different and you are sensitive enough to tell. It doesn't sound like you have a problem. It seems that you are detecting exactly what I detect when I put my winter tires on after the summer. Quoting from the Tire Rack article: New winter tires begin with deeper tread depths and more open tread designs than the tires used ...

I pulled the tires off and inspected the front end suspension and steering, and found that the sway bar linkage on the drivers side was detached.

It sounds to me like the previous owner suspected an outer CV joint (which was my first thought when you described the problem) and changing it didn't fix the issue. I would double check that the outer CV joints look new and there is a good chance the problem could relate to one of the inner CV joints. Diagnosing the problem will likely be a case of ...

You need to identify the source of the leak Clean everything in your driveway. Use Gunk, water soluble, or the like and get the Power Steering Fluid gone. Then: Allow everything to dry out. Validate any leaks...mind you, you have not started the engine since you cleaned EVERYTHING that could be consider oil out of the engine bay. Now, start it and run. ...

If you have worn out steering parts, these can cause your issue, worn parts cause slack in the steering, when you brake it will pull to the side which has the most slack at the time. You can test for steering slack by starting the car, leave it park, set the brake and roll down the drivers window, get out and reach inside the window and rock the steering ...

After some reading, it appears Jeantaud's mechanism uses shorter lever arms to acheive a more accurate effect. However, both mechanisms (Ackerman and Jeantaud) are sensitive to a number of things, wheelbase, speed, and body roll from suspension travel - namely toe changes (and to a lesser extent camber changes). Mechanically these mechanisms are quite the ...

As Paulster2 says, as far as your car is concerned, it really doesn't matter, but if your parking brake/gear fails (from being tapped by another car, e.g.) you want the curb, if there is one, to act like a chock block. If there is no curb, then you want your car to roll away from traffic.

It seems this issue is caused by one of two things. Bad steering sensors that are mounted on the rack Steering sensors need to be 'aligned' Problem seems to be that the sensors in the steering rack that tell the electric assist motor the position of the wheels and which way to boost the steering, left or right, are out of alignment. So there a sub-second ...

from what you've said it sounds like an issue with the rear tyres, mismatching different makes of tyre's can throw the handling out as they all have different tread patterns (even more noticable in the rain because they aqua plane differently) couple of other things to check would be - Check all the wheels have been balanced properly check all the tyres ...

Depending on how well you know the feeling, the symptoms sound like they could just be a brief slip into oversteer: As the back end loses traction (which could be the case based on your description of the tyres) the car will feel like it is suddenly turning too much into the corner. Normally, however, once you lose the back end, it doesn't come back by ...

I have seen these symptoms caused by a snapped rack in the steering rack. if this is the case with your car, it is very dangerous and the car shouldn't be driven until the rack is replaced. Put your keys in the ignition to turn the steering lock off then jack one wheel up at a time and try to 'steer' that tire with your hands. You should be able to see ...

Here's a diagram of a rack and pinion steering system: As you can see the rack connects the two front wheels. Which means if they are turning independently something in the list from @rpmerf or the rack itself is broken. It's also very clear that the car is not safe to drive since the wheels can go their own independent ways. That's a crash waiting to ...

I disagree that this is a wheel alignment issue, as the car is pulling randomly to either side - I'd expect alignment to either show no pulling, just tire wear, or to pull consistently to one side. I suggest you take the car to a mechanic you trust, and get them to check out the calipers - sounds like they may be sticking randomly. You don't say how old the ...

My first suggestion was going to be the wheel bearing. It still might be one of the rear bearings. I had this problem with my '06 Pontiac and the wheel hub (including bearing) was surprisingly cheap and easy to replace. You should be able to inspect the rear bearings much the same way as the front bearings. My second suggestion would be the CV joints. The ...

I had this in one of my Mk1 Golf GTI's and what had actually happened was that the bulkhead had corroded and the steering rack mount came away from the bulkhead which caused the steering column to disconnect from the rack thus loosing all steering. Thankfully it happened at a low speed. Definitely a weak point on the Mk1 Golf and anyone else reading this ...

I've had this behaviour on a number of vehicles and a number of time. Each time it was caused by a different source. These included; Worn out engine mounts causing the engine / gearbox assembly to move around on and off throttle Worn out rear wheel bearing so there was excessive play and the rear wheel was effectively causing the car to rear wheel steer ...

After referencing the comments above and taking it into a different dealer, I had it confirmed that it was the rack. It is a known issue with Audi's electric steering. They fixed it by replacing the rack.

I'm not sure which pulley you're talking about, but would assume it's one of two: idler or tensioner. This is the pulley system of the 97 Lumina (should be the same for the 3.1 or 3.4 engine): Since this setup doesn't have an idler pulley, it would most likely be the tensioner pulley which is not aligning (if not the tensioner, please tell me which one ...

Today, we don't only have cruise control. We also have cars which can park the car automatically in a parking spot. The driver just sits there and monitors the car, may be, he is responsible for gas and brake, but the car actuates the steering wheel. So, you just need to know how to use this for your own projects.

From Ben's comment, It's probably just a coincidence that the pump shaft seal started leaking. Universal fluids are used all the time and the Toyota power steering pump isn't anything special. Either way the pump has to be replaced/rebuilt You either need to replace the pump or rebuild it. Also, if you flush the system, or have done prior to the leak ...

What you are most likely experiencing is the pull from tires when breaking on uneven surface or road with grooves from heavy vehicles. If you have rather wide, sticky, square tires, this is what it would be. Notice how water stands in sort of lines, that's where the grooves are formed from vehicles. Depending on if you are closer to the right side of the ...
