is the service engine soon light on? have it scanned to see if there are any codes present. driving it in 4hi should be a problem but 4lo would be a problem it wouldnt probably get up to 55mph. but anyway i would check for codes and see if there are any technical service bulletins, available on many sites.

Many things can cause this no one really knows what she may have done here. , could be damage to the transfer case, someone has to check out the 4wd system for a proper diagnosis.

The transfer case electroinc encoder and dash switches were troublesome.
