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 ...

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 ...

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 ...

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 ...

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 ...

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.

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 ...

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 ...

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 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 ...

It sounds like the vehicle is near the end of its life - I'd try removing the drive shaft from the transmission to the rear diff. Note: I'm basing this advice on the Top Gear South America special, where they ended up turning a jeep into a front wheel drive vehicle. In theory, it should work, as long as there aren't a lot of fancy electronics & ...

4WD is distinguished from "part time" 4WD in that you can't turn it off - the vehicle is always in 4WD. Vehicles that have this usually have a differential built into the transfer case to allow for full time 4WD even on dry pavement. AWD is almost the same as full time 4WD, except that AWD vehicles generally don't have the high-torque low gear option (4L) ...

I have a 1991 Chevy Tracker on which I will be isolating the rear differential. The reason is that the pinion bearings have had extreme lube starvation do to a axle seal leak which lead to catastrophic failure. The vehicle value doesn't compare to the price of a new/used rear end, or the time it would take to pull each component and inspect for wear/damage. ...

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 ...

Nothing wrong with spending time and money to do interesting things to old vehicles. I'm guessing you have the model with the 4g64 engine? If so, why not do another 4g64? It's still being used on modern vehicles, you may not have too much work to do to fit a current generation 4g64 into your old vehicle. Might be a difference in crank/cam angle sensor ...

I had the same problem.. but when i shoved the gear shifter into reverse hard and shook it hard it flashed. So what i had to do was take my dremmel and grind the part of the switch base below the threads down to allow the threads to screw further into the transmition. I took off about an 1/8 of an inch and Now everything works as advertised.. :-)

The general consensus on this is that it depends where you are intending to go - you want something that is common in the local area so that parts are readily available. The two standard choices are Land Rover (either Defender or Discovery) or Toyota (LandCruiser or Hilux) - Land Rovers tend to be more common in Africa, Toyotas are more common in Asia. Both ...

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 ...

In a perfect world you shouldn't. However because the the front power train is now engaged you now have more moving parts. More moving parts = more/changed vibration and noises. I would wager what your are perceiving is just normal operational byproducts of the front power train. Also the front drive train is now connected to the transmission which is ...

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 ...

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 ...

Zaid has covered the mechanism of the gearlever and its switch and relay. The speedo is made up of a driving wheel on the transmission output, which is an interferance fit, which can go bad, and not do any driving of the speedo transducer. The speedo driving wheel drives the transducer, which gives out a sequence of pulses to the ECU to give a 'speedo ...

There is likely a seal that holds your gear oil in place on the shaft. Also, assuming you bought these online and installed yourself, did you verify them to be the same length and also that the shaft sat all the way into its seat? If it did not seat it could have wiggle room that allows it to slide in and out, instead of flex.

Thanks to some helpful people here and on the Australian 4wd forums and a local gearbox repair place I have found a solution. Apparently the gearbox the the MJ Triton uses a ball bearing above the reverse switch. The gearbox pushes it down (pushing the switch) when in forwards gears which opens the circuit and turns the lights off. In reverse it lifts up ...

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 ...

I have seen an old series 3 Land-Rover used quite successfully in this fashion, however they are a lot more agricultural than a relatively modern Toyota and so are more capable of taking the abuse. A lot of it will be down to the design of the transfer box - in the case of the Land Rover it was a simple mechanical lock, which either drove just the rear axle, ...
