How does the 4wd lock work on awd 2013 kia sportage

Its automatic. AWD is different than 4WD. AWD keeps all the wheels working independently. Where 4WD keeps all wheels working no matter what. No need to worry about anything on an AWD set up. Speed doesnt matter, however in my opinion stopping and letting it kick in or out is best. Just in case a part acts up it wont do anything odd at high speeds.

98 Nissan frontier,4wd wont engage,lock in hubs manualy but they will not engage

If you have turned the lock tabs until they click in or out which ever the case may be for 4wd drive then maybe the transfer case is not selecting 4wd If it is vacuum actuated or electronic operation I would be checking their actions be for e I went any further.

4 wheel drive light flashes, wont lock in but transfer case seems to lock just not differential

You didn't specify which vehicle model you have, but most gm vehicles use vacuum to activate the 4wd system. Check all the vacuum lines you can locate for loose or disconnected line, cracked or gummy feeling lines. If you have the push button 4wd, listen for an audible click when you push the 4wd button. If you don't hear anything, the push button assembly may need replacing. If you did hear the click, then look under the battery tray for a loose vacuum line. Most gm 4wd problems are vacuum related.

4 wheel drive will not engage

there is a 4wd actuator on bottom of front axle that is operated by vacuunm pressure when u press the TOD 4wd button. Lesson learned that if u dont engage in 4wd at least briefly every other month u lose your 4wd. Would have been nice to know before it snowed!!!!

U can replace by getting one from a junk yard or do like I did. Crawl under truck and switch the two hoses. It reverses flow and locks the hubs. U wont have the fancy TOD but it will br rocking in 4WD. When wanting to go back to 2WD reverse procedure.
