Problem With Front Diff Lock For 4 Wheel Drive?

Posted

My son has my 98 2500 4x4 now and the other day he needed 4 wheel drive to get up his hill, and i noticed both rear wheels and the passenger front were spinning, but the drivers side front was not.   I always thought all wheels spun on these in 4x4 mode?   Any suggestions to what may be happening? 

 

Thanks

 

Rick

There is an axle lock on the back passengers side of the front axle. Its vacuum operated. Check the lines at the disconnect and see if there is vacuum in 4x4

Your front axle is an open differential meaning you only get power to one wheel.

Axle lock works, but i think MnTom may have solved my non problem then.    I always thought these had Trac Lock, kind of sucks it isn't.   Thanks for the speedy reply and possibly saving me frostbite trying to diagnose this!

He should be happy he had 3 spinning!

Nothing short of dual lockers will give you true 4wd.
