To expand a little on what Eric said... I consider the 4WD versus AWD to largely be marketing terms differentiating between vehicles with additional ground clearance and plating underneath to protect sensitive components while going over rough terrain off-road travel (4WD) from systems that are targeted more towards on-road travel (AWD). Though this is ...

I really think that it's more of a naming convention issue but there is a marked difference between 4x4 and AWD. In 4x4 all the wheels are "guaranteed" power. Power is sent from the engine to the transfer case and then the transfer case sends it to the front axle and rear axle. The reason I put guaranteed in quotes is because there is such a thing as full ...

As has already been noted, anything rubber will have perished and will need replacing, as will all the fluids and any other normal perishable items (brakes, battery, filters etc). The brakes will have siezed on, and depending how dry the garage was, the interior may have mould and the bodyshell may have gone rusty... The biggest risk, however, is that the ...

First of all, anyone who is off-roading knows the inevitability of a roll over. It happens; you deal with it. If you have an expectation of never rolling over or never scratching the paint, then keep your vehicle on-road with the rest of the highway queens. Once any trail damage occurs, you'll have dents. Rolling a vehicle over may just cause your rig to be ...

No, it cannot. In fact, in the United States it is illegal for a tire shop to repair a tire which has side wall damage. The reason for this is because the integrity of the tire itself is compromised with side wall damage. Now, I'm not saying it could not be fixed per se (a simple patch could probably do it), but would you want to risk your safety or that of ...

My first thoughts, given the car is question, would be to check to see if there is a performance version of the car which features four wheel drive. For road use, if you have over 300bhp going through the front wheels, things can get difficult. A friend of mind had a 320bhp Seat Leon Cupra (Front wheel drive) and sold it to buy an Audi S3 (same basic ...

One of the things the other answers neglected to mention and is probably the key point between AWD and 4x4 is that AWD transfer cases will almost always be a single speed differential. The 4x4 will almost always have 4-wheel high and 4-wheel low ranges and be selectable. This provides more torque if the driver deems the situation to need it. 4x4 may also ...

Tool list: Several large/long tow straps (30ft each or longer recommended) Portable electric winch and battery, in case your buddy is not there to use his winch mounted on the front bumper. Some 4"x4" wood posts from the lumber store, different lengths up to 8 feet, they make good prying instruments, longer the better. Large Come along or two if you ...

On page 186 of the owners manual there are instructions that tell you what to do when this indicator blinks. Highlighted below: (highlight added for emphasis) Given that you've tried shifting to different modes several times, you may not know what mode it thinks it's shifting from. You may be able to simply go through all the possible sequences ...

The letters are standard: Park Reverse Neutral Drive Sport (or possibly Snow - thanks @Brian) Braking (usually for going down hills) None of these have anything to do with 4WD or 2WD selection. If your Daihatsu is the 4WD version, it is permanently 4WD - there is no selector on that spec of car. It was a specific Japanese edition. You have stated ...

One of the valves in the brake servo (booster) is stuck open. When you start the engine the vacuum produced by the engine (or a separate vacuum pump) is used to assist braking pressure from your foot. As you press the brake pedal, a valve in the servo opens to allow the vacuum to pull against the diaphragm in the servo to assist you. If a valve is stuck ...

This is something I've commonly heard said, usually by tire salesmen, but I do not buy. The difference in speed of the rotating tires between 6/32" is very small and likely less than many other factors such as alignment and tire inflation differences. The differentials are meant to handle small differences between the different tires rotation speeds and ...

I had the same problem, it was a vacuum line for me. I found the leak, fixed it and the light no longer blinks. So check out your vacuum line for leaks.

Before you start, I'd have a good read of the rules applying to it - I seem to remember that Germany is very strict on heavily modified cars, so you might well find there are restrictions on what you can do to it - modifying the monocoque (chassis/bodyshell) to allow the fitment of a propshaft and rear drive axle might well be restricted, or involve huge ...

I would really question this approach for these reasons: The vehicle wasn't designed to run in 4WD full time. This may put extra strain on the frontend and wear out your front drivetrain and other components. The vehicle wasn't designed for the front-wheel drive to handle all of the force of moving the vehicle. Again, this may put extra strain on the ...

Different outer tire diameters creates a different rate of rotation for each wheel. Depending on the design of the differential, maintaining higher speeds for a lengths of time with great enough differences in rotational speeds can create too much heat, which I imagine leads to break down of the lubrication and damage to the differential. It would be wise ...

In regards to most pickup trucks 2WD - RWD — only the rear wheels turn. If the diff's have limited slip they will allow some variation across axles in tire speed. 4WD High — all 4 wheels are driven. If the diff's have limited slip they will allow limited variation across axles in tire speed. 4WD Low — all 4 wheels are driven. All diff's are locked. This ...

All Audi Qauttro's have a driveshaft that connects the front differential with the rear differential. Your car does not have 4wd if it does not have a driveshaft. In my country (Denmark) you can add the car to your profile at https://my.audi.com and add the VIN of the car. Then you can see all information about the car including factory installed options ...

To answer your question, it seems like you didn't buy a Quattro. You bought a FWD car, unless Audi invented some way of transferring power without a drive shaft :(. You might want to talk to the person you bought it from, and bring it to their attention.

While this is not "scientific data", I did find some empirical data on the subject from this website. The author talks about his experience with the Honda Pilot and its VTM-4 system: Reading about VTM-4, the way I understood it to work was this... Under normal conditions, the VTM-4 system is FWD biased and transfers power/torque to the rear as ...

Is it possible to bleed the clutch hydraulics? (I don't remember if the Jeep has that option off the top of my head.) If so, this is where I'd look first. If not, I believe you need to replace them. It seems as though the clutch is not quite letting go when you depress the pedal. The five seconds gives it enough time to spin down. The fact that you can drive ...

There is one other thing that can cause what you are describing. There is either a pilot bearing or a pilot bushing that supports the input shaft of the transmission. I don't know which, but if it is a bushing, it would make sense based on your description. If the borrowers slipped the clutch quite a bit and were in a position to use the clutch a lot, ...

4WD has the best traction in off road conditions, which is mainly what most larger vehicles are used for. As well as this, 4WD offers better fuel economy which is generally more favorable in a larger vehicle as these will already have a greater fuel consumption due to their added weight. You are correct about AWD being at least as good in conditions such as ...

Check under the rear of the car you should be able to see the rear differential. it is the aluminium finned item between the rear wheels If you don't have on then you definitely don't have a quattro, you should also check the VIN to make sure. The driveshaft it self is kinda hard to see depending on the angle. If your car was sold to you as a quattro ...

I would say that it is not a safe assumption. There are three main places where a wheel could be loose at, assuming the lug nuts are tight. Those are the wheel bearing(s), upper/lower ball joints, or at bushings at the base of the control arm. You might also be getting deflection out of your tie rod ends or steering rack (if equipped) as well. You could also ...

They should feel very different! When cornering the difference is at it's greatest. Instead of the general understeer a front wheel drive car will trend to do through a corner because traction is broken relatively easily when accelerating through a corner, you will expect a four wheel drift as all four wheels will be able to break traction. When ...

From the info I have been able to gather the 4runner came with 225/75R/15 or 31-10.50-15 tires. In order to determine if your wheels will work you nedd to determine the rim width. Many OEM wheels will have it stamped on the wheel. Finding it may require removal of the wheel, some stamp it next to the valve stem. You may be able to get a good estimate by ...

It matters, but how much it matters varies from vehicle to vehicle. TireRack has an article about this topic -> Matching Tires on Four-Wheel Drive and All-Wheel Drive Vehicles Here is the Manufacture Specific info from the end of the article: Here are recommendations from some of the manufactures that Tire Rack currently serves for matching the tires ...

You'll need to check/replace for all rubber hoses(brakes, power steering, radiator, vacuum,...) as they could have dried and may break under load. Check wiring, they could have corroded or dried and can cause shortcut. Grease parts (Drifeshafts, steering, ...). Get a factory service manual for your specific vehicule and check the maintenance items, they ...

I have my 1990 Toyota V6 3.0 extra cab running on the front two wheels only, I had the same thing happen. I was told, a friend of mine, drove a similar truck all the way from the desert into San Diego. I've been driving the truck all morning, the deal is, I have a "High" 4x4 and a "Low" 4x4, right now I have it engaged to be High 4x4, I am not using the ...
