I have a 98 Pajero and don't know if tech is different. Mine has super select so its fully auto.
Pl be More specific. I think ur front shaft is not engaging properly. Plz have vaccum box, vsv, vacuum pump check. Also get ur car on lift and try rolling it in 4x4. R all four getting power?
Don't use 4x4 until it is rectified, might be a serious issue.
