Is it harmful if I chose to drive 2WD mode for my 4WD Renault Duster specifically when I am driving in the city?

Why do pickups and large SUV's use 4x4 and generally not AWD?

Is it harmful if I chose to drive 2WD mode for my 4WD Renault Duster specifically when I am driving in the city?

Don't use "Lock (4WD)" mode unless on soft terrain. You will get increased wear of tyres and transmission, worse directional stability and higher fuel consumption for nothing in return. ...

4x4 for sports cars (street use)

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 ...

Why do pickups and large SUV's use 4x4 and generally not AWD?

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 ...

Is it harmful if I chose to drive 2WD mode for my 4WD Renault Duster specifically when I am driving in the city?

I will offer a counter-point to all of the current answers which indicate using 2WD "except when you need 4WD". In general, I will agree that 4WD isn't necessary and the 2WD (front wheels ...

How to tell if the Control Arm is bad too, or just the ball joint

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 ...

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 ...

Manual transmission difficult to put into gear. Do I need a new clutch?

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. ...

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.

Leaf spring preparation

Beyond what @cory says, once you get them hung on the chassis and the weight of the diff dangelling on them, the leaves will open up and you can squirt in some marine-grade grease. This will let the ...

I'm assuming that model has a simple 4WD transfer case and not one with a front-to-rear differential. That means that there is no "slip" in the driveline. Generally you feel this when you try to ...
