How do I activate the 4 wheel drive for snow highway driving?

If there is an option to run 2wd, that would be the most fuel conservative option. You shouldnt need 4 wheel drive unless you are driving in snow and or mud, or need extra torque while towing a load. 4 wheel high would be the most common under the given circumstances. 4 wheel low is a lower ranged gear that gives you more power to climb hills or remove your vehicle from "sticky" terrain.

There can be a linkage adjustment problem. Also you may need to remove transfer case housing to check the spring inside. There is a chain inside. That one should be checked for its tension. If those are ok you may need your transfer case get serviced.

I hope so, it shouldn't be in 4 wheel drive unless you need it, 2 wheel high is where it should be when driving habit are on city streets or highway driving.

The switch is to put the vehicle into four wheel drive for off-road and increased traction on snow and ice.

Hi

Full time 4 wheel drive should be used on rugged and difficult to drive on terrain, this could include adverse weather such as deep snow, mudslides, sand dunes etc.

Part time would be used on terrain that is irregular where some parts of a track may be road and other parts rocky, mountainous regions combined with any of the above weather conditions. The 4 wheel drive should not be used for normal driving as it will only over time damage the gearbox, the 4 wheel system is not designed for speed but purely for grip and stability.

Hope this helps

With the Jeep in park, move the left shifter to 4 wheel drive. Proceed to put right shifter into drive, proceed to drive. Only use 4wheel drive when neccessary...ie...snow, mud, use 4 wheel lo in steep incline or when really bogged down.

Hope this helps

use part time on wet or slippery road surfaces. Use full time in snow.
Though some will shift into different modes at a standstill, I generally do so when rolling at 5-20mph...it makes engagement easier on the transfer case. when driving on dry road surfaces, why use 4x4? it uses more fuel and really has little benefit. differences in front/rear wheel speed must be absorbed by transfer case alone, while on slippery surfaces, a bit of tire slippage reduces stress on unit.

That is up to your preference in my opinion. 4 wheel may give you a little more traction, but it can also lead you into a false sense of security. If heavy snow, and you need to get through it, you can only go as fast as the guy ahead of you anyway right? Up here in Ontario Canada, I passed by many a 4 wheel drive in the ditch, because they assumed they would have a better chance on icy roads than me, with 2 wheel drive. Remember this, no matter what you decide, you may be able to go a little faster in 4 wheel, compared to 2 wheel, but when you have to hit the brakes, or go into a spin, 2 wheel or 4 wheel drive, your not going to be able to stop it any faster. Your going to use more gas in 4 wheel too. Yes there will be times when you need to use it, but like I said, when it goes sideways or you have to lock up the brakes, because you were pushing the envelope too much,? At least with 2 wheel, you feel the back end break loose, to warn you how slippery it is, and you may not feel that soon enough, with 4 wheel. Just my opinion, but maybe some 4 wheelers have a different opinion. It's just like the experts from the skid school said up here about mandatory snow tires being talked about. If putting snow tires on your car is going to make you drive a little faster, your defeating the purpose.

sounds to me like the transfer case clutches are worn out. also the fluid could be low or dirty. try draining and refilling the transfercase with clean fluid. if it is still not working after driving it around for a few miles then you may need to replace or overhaul your transfercase

the quad trac is an alltime 4wheel drive system. it does have a control module that helps transfer the power from front to rear. if it is a 2008 it should be under warranty and you can have it checked out for proper operation
