I've got 2nd gen 1991 hilux surf 1kz auto transmission 3.0 diesel. Is there anyone can tell me what is the steps to engage 4wd. The dashboard's 4wd indicator won't even turn on when I pushed on the 4wd button. Please help.

This is for a 1996 SSRX, KZN185

A while back I had the front prop reconditioned and all was well.

I've just started getting a very brief grinding sound on engaging any kind of 4WD. It works fine once engaged and doesn't do this when disengaged.

Weather today...
