Brief history, bought a 94 suburban took it to Rockypoint, mexico. The 4x4 was working ok. Sometimes would grind while trying to put it in 4low, had to shut off engine put it in 4low then Start the burb back up and it was fine. Then I told the wife(soon to be ex)to put it in 4high while on the beach and take it out of 4x4 when on the street. Well it seems she put it in 4LOW was not able to dis-engage it and drove around on the streets in 4low. I had no problem taking it out of 4low. Went on the beach again, 4x4 was working fine. When my wife was ready to leave she burried the suburban. Noticed that the 4x4 was not engaging 4low or high(the indicator was not showing in 4wheel nor would the front tires move). <br>Does anyone know what the problem could be? Any help would be greatly appreciated.<p>You know the worst part..... I was pulled out by a Ford Ranger!!!
