Replaced the Freewheel Clutch Valve and it fixed the grinding noise. See the post https://mitsubishiforum.com/forum/sh...ad.php?t=37680 for more details, and thanks to all here for your inputs.

I seem to be having the same problem, based on the initial description. My mech says it is the differential. Could this be a side efect of the solenoid going bad?
Allthough the grinding noise only occurs while Im driving and it stops only with a "tunk" like noise when I come to a full stop.

Only difference between yours and mine seems to be that you're saying yours does it the entire time, where as mine was intermittant. I'd find it unlikely that it's the differential, theses things are built like tanks. May want to test the solenoid packs or the freewheel valve's first before dropping differential $$

The solenoids were fine, had to replace and fix some of the internal front diff gearing; although, there was a faulty conection to the solenoid pack, which caused wearing of the coupling and so on...
Bought that car used...

I had the same griding noise coming from the front end of my Montero. It always occurred in 2H. After reading this thread, as a diagnostic step I put the car in AWD mode (4H) and the noise did not re-occur. This confirmed the freewheel valve solenoid malfunction. Replaced it (it is about $100 now) and the noise went away. Thanks for the help with diagnosis.

Gentlemen, if you need to change the wheel hub assemblies, you can get it looking for the timken part number: HA590039 Rear; HA590145 Front, for Montero 2001 to 2005. It costs aprox. USD 140.00 each. I changed it in my Montero 2002 3.5V6 Gls., about a year ago.

Yes, that was it
We took the advise about the solonoid and it worked! I went online and found the part from a Chinese company for $16.00 including shipping. I learned that the Montero is known as the 'Pajero' and the part is called a 'super select'. I would have spent tons of time finding the issue and tons of money trying to get it fixed.
I want to thank you for your insight and for sharing your knowledge.

i have done several of these. 1 a few weeks ago. customer complained of bad grinding noise at times when comming to a stop at high speeds or at very low speeds. 1st one was a b*#!@ to diagnose but it was it was the solenoid pack that controls 4wd engagement. loses vacume when comming to a stop and the 4wd slightly engages and thus the grind you hear. that solenoid pack is located on the passengers side wheel well area in the engine compartment. not very expensive. around 50 bucks. not hard to change either. just watch your vacume lines and dont mix them up. good luck!!
