Symmetrical all wheel drive, like in a Subaru, no. Most else, yes. The front wheels turn faster than the rear, so you can imagine how hard that would be on a vehicle.
When you drive over a clicking bettle.
yes
If your talking about it turning on while you are driving, this is normal. All wheel drive is basically 4-wheel drive that only turns on when you need it to. This happens automatically, and that's why your seeing the light turn on and off
Generally speaking, a front wheel drive vehicle is better for driving in snow. This is because the weight of the engine rests on the driving wheels, allowing them to achieve better traction.
The benefit of driving 4 wheel drive cars is that you have the option to engage or disengage the four wheel drive when you need to. Four wheel drive is great on low traction surfaces (off road, snow, etc.).
Not usually, the four wheel drive is hooked up after the transmission. If you are having problems with your transfer case it will sound like the transmission because the transfer case is bolted to the back of the transmission. The four wheel drive operates independently from the transmission. If you have a bad transfer case that would cause locking in the drive line it could cause problems, but your vehicle is designed to use the four wheel drive and typical use of your four wheel drive won't cause damage to the transmission. It would be advisable to only use it as necessary because it will decrease your fuel economy by about 20%.
All wheel drive means all 4 wheels are driving the vehicle. RWD means only the rear wheels are driving the vehicle, and FWD means only the front wheels are driving the vehicle.
Rear wheel drive mechnism
2 high, is 2 wheel drive which is where you should be when driving on the highway.2 high, is 2 wheel drive which is where you should be when driving on the highway.
It is not safe to drive. Possibilities for cause, maybe wheel bearings, brake pads worn down to steel backing plates, if its front wheel drive there are even more possibilities. It has to be repaired before further driving.
For the most part and under normal highway driving, driving in 4x4 is just like driving in 2 wheel drive. When things get slippery or the surface more uneven you get added traction and grip on the road. Keep in mind that although traction is improved in four wheel drive, braking does not improve.
It depends on if it ie front or rear wheel drive or 3 wheel drive. If it is 4 wheel drive, it is not good and will cause problems. If it is either front or rear wheel drive keep the wheels the same on the drive wheels ie. front wheel drive, keep the 17 or 16 inch wheels on the front but make sure they are the same.
