New montero owner with questions? - Pirate4x4.Com : 4x4 and Off-Road Forum

abcdyno · 05-21-2010, 02:58 PM

Just bought a 89 swb montero for a killer deal runs great, only problem is it roars a bunch when I turn in either direction... What would cause this? And I'm looking at a 4D56 Mitsubishi diesel and was wondering what auto tranny works with this engine? Will the tranny in my 3.0 work on a 4 cyl diesel?

You need a 2.6L automatic bellhousing on the V6 transmission for the 4D56. It will be a little more complicated than that though.

Steering, if it squeaks at full lock then thats normal. If you want, put new rubber on the steering arm stops.

Thanks for the info... I don't want to sound stupid but the bellhouseings come off these automatic trannies on these trucks? I'm used to American trucks.... And the roaring is coming for the rear diff Of my truck

88mitsu · 05-21-2010, 05:38 PM

yeah, its an aisin trans, similar(but not the same) versions were used in toyotas and jeeps

Don't know what to tell you about the rear, check the fluid/brakes? Is it a LSD diff?

abcdyno · 05-21-2010, 07:26 PM

Haven't had a chance to check the fuild, but I do know that it's a LSD

abcdyno · 05-21-2010, 07:49 PM

Having trouble finding a 4 cyl automatic bellhousing... Any idea where I could find one

Also try 4x4Wire.com there are a cople of guys who regulary part out monteros, in addition to the 4 cyl bellhousing you'll need the 4cyl flexplate and motor mounts moved a bit.

could be the rear end but doubtful. check your diff fluid.

it could be the brakes. or it could be a wheel bearing but they tend to scream....

abcdyno · 05-24-2010, 03:32 PM

Yeah it only makes any noise when I'm In a turn.. With only 108k on the clock I doubt it's the diff as well, but haven't check fuild yet.... Thanks
anymore input would be greatfully appreciated

Do you have automatic hubs? They might not be disconnecting so the axles are turning also. When the CV joint wears out they will make noise when you turn. It usually is a loud clicking or if you are going faster it will sound like gear noise. Just another idea.

abcdyno · 05-25-2010, 08:02 PM

Checked the brakes.. They were fine.. Looking for the fill plug on the rear end and I though I had found it and when I unplugged it almost all of the fluid came out.... So do I have to tear this rearend down to fill it with the rear chunk out, since there's no fill plug on it like on a 9" ford rearend?

abcdyno · 05-26-2010, 05:51 PM

My pinion gear has 4.98 on the top of it. Is this my ratio?

Probably.

rxinhed · 05-29-2010, 09:59 PM

The typical ratios for Mitsus are 4.625:1, 4.88:1 if you have the Winter package. The fill plug is located on the rear of the diff, about 1/2 way up.
