my 1st post! needed help asap. possible diff prob

[jaosnyc]

Hi all ! I have a 01 montero (65k miles ) and lately I've been having alot of problems with it and I'm wondering if anyone in here can help. I suspected my differential have problems but yet when I took it back to the dealer, no problem had been found !!! I'm so stressed out it's been the 4th times I took the truck back and all they said was can't find the problem.

1: Whenever I go a for a drive for bout 40 mins, my c/d lock indicator WOULD blink back and forth and all the lights on the 4wd would be GONE!! This is scary. I had to stop the car and turn off and on again to kinda reset it, otherwise if I wanted to shift it to 4wd, there's no indicator whatsoever . I even took a picture of the light that's blinking and gave it to the dealer but still nothing has been fixed. They changed the ecu for the transfer case, changed the fluid for the differential.. and etc but nothing is WORKING !!

2) This noise is really annoying and scary. On a normal basis driving, out of nowhere, I would hear a loud noise coming from the differential.<< not so sure. It sounds like it tries to lock the hub. If I give more gas, it would sound louder and louder.I have to come to a COMPLETE stop and A LOUD THUMP ( i assume it finally locks the hub).

I have 20" rims 295/45/20. COULD THIS BE THE PROBLEM ??

Please give me some advice on how to solve this problem. I love my truck. I have done alot of stuff to it. I don't want to sell it YET. My friend told me to go to mits to complain bout the problem but I just dun know where to start ? mitsubishimotors?

p/s: if ur a mechanic, preferably a good one =) and in nyc, maybe i can stop by at ur shop so u can take a look at it.


peace

I was told by my Mitsu service advisor that plus or down sizing the tires any more than what it is decaled for will ruin the drive train. You put the 20" wheels on it when it is supposed to have only 16"'s. Try switching back to the factory size and drive for a couple of weeks and see if it goes away.
Also have the dealer check to see if the "freewheeling" switch is bad.
I have 63k on my '01 and have zero trouble. Best truck in the world as far as I am conserned.

Hi ! Thanks for the reply guys. I'm not quite sure if the sizes really matters. If you compare the caddys and all other trucks, they went from 20 to even 26". I dun think that it'll ruined the drivetrain. Also, my dealer replaces the freewheeling switch already but I still have the same problem. I might go ahead and get nother set of wheels because i have to do the allingment again once u swap different sizes for wheels on the truck. i'm thinking bout getting the volk wheels te37 ( forged and light as hell ) but also pricey. any input guys?

i have the 2001 montero too, only 57000k, i have the clunking nois when i drive at 40miles/hour, take off the foot from the panel, then step on the gas little fast, i hear the clunking noise from the rear. mitsubishi said the sound normal, due to the movement of rear diff.. but they redesign the 2003 up. no more of this noise. they refuse to fix my truck

Ever find out what the problem is? I have a 2003 Montero and I've run into a similar problem.
