Basic Montero info #776626 01/02/07 05:50 AM
Anonymous

Greatings everyone. I am considering buying a Montero but have not been able to find the kind of info I am looking for. I'm looking into something like the '98 Montero, NOT Sport. I spent the last 2 hours looking throughout the forum but have now given up and will ask. <img src="/forums/images/graemlins/confused.gif" alt="" /> I'm not a 4wd noob, so lay it on me. I'm just new to the idea of owning a Montero

1. What is the low-range gear ratio on the Monty's?

2. How do I identify Monteros equipped with the rear locker?

3. I've noticed in photos of the transfer case shifter 2H, 4H, 4H Lock, and 4LO Lock? Is that correct? So you can run 4H like a full-time 4wd if desired, or lock the t-case diff when needed?

4. What's the axle gearing for the above described Montero? 4.625?

5. And, uh, what's up with mitsubishisucks.com?

Thanks ahead of time for your responses <img src="/forums/images/graemlins/cheers.gif" alt="" />

ok, 94-96 monteros with 3.5L engine have 4.6 final drive ratio. 97-99 monteros have 4.2 final drive ratios. if you are mechanically able enough, you can buy a 98 or 99 montero and swap 4.9 gears into the diffs. you can get the 4.9 from dealer, I have the part numbers if you want them.

I am not sure what the transfer case ratio is stock, but I know you can get 3.15 transfer case gears made in austrailia for 1000 bucks shipped to the US and they make a huge difference in crawling abilities, cap510 on this forum did the 3.15 t case gear swap, he can tell you lots about it, I have my t case gears, just didn't get them installed yet. with this modification, I don't think anyone will come close to the crawling abiliy you will have with them, especially if you put 4.9 in the diffs.

it is easy to see what monteros have the rear locker. right under the radio but in front of the t case shifter, there is an accessory socket (12 volt). right next to that socket there will be one of two things: a brown retangular plug or a black rocker switch that says R/D Lock. if that switch is present instead of just the brown filler plug, it has the locker. other identifiers include an orange warning sticker on the driver side of the middle console next to gas pedal. Also, if you turn the key to ON position and the little orange rear diff light on the dash below the fuel gauge illuminates for about 5-10 seconds and then goes out, you know your rear diff lock system is present and in working order.

about active trac system:

2H is just what you may think it is, 2 wheel drive with rear diff open.

4H is like all wheel drive, 70% power goes to rear end and 30% goes to front end. there is a differential in the t case that links the front end to the rear end through viscous coupling and when in 4H this center diff is open allowing the front and rear ends to spin at different rates.

4H lock is when the center diff is locked, true 4wd. front and rear diffs are still open.

now to shift into 4LO lock, vehicle must be stopped and in neutral. same as 4H lock, except lower ratio via t case low speed gear.

as far as the rear diff is concerned (if you have one equipped) rear diff will work ONLY if center diff is locked. if center orange light on dash is illuminated (meaning center diff is locked or is in the process of locking) you can press upward on the R/D lock switch I talked about earlier. this will activate a compressor that expands the rear diff lock actuator inside the rear diff locking your rear axle completely. when rear diff is locked, at least 3 wheels must spin at any given time (both rear wheels spin no matter what, and since front diff is still open, at least one front wheel will spin).

that web site you speak of is just some dumb <img src="/forums/images/graemlins/butwiggle.gif" alt="" /> that isn't smart enough to understand how these vehicles operate and they can't figure out the purpose behind their design. My parents have had a 1991 montero with 250k miles on it with very minimal maintence done to it. they now own a 99 montero that has had no problems except a few burned out bulbs. I have two 97 monteros that I wheel regularly and can't seem to brake anything on them (yet). and lastly, my brother has a 99 montero and has had no problems with his either. I can confidently say, having had experience with 5 monteros in my life that they are excellent vehicles designed with durability in mind. they are not the easiest to work on b/c they are complicated, well they are made by japanese, but I feel that is why they are such good vehicles when it comes to performance.

Scottie,

Thanks for the info. Glad to see that your experiences have all been possitive. If I decide to get one, it will have to come with the factory locker as it looks like ARB does not offer theirs for the 3.5L's rearend. Hopefully it won't be TOO hard to find one. I like the big 9.5inch ring gear and 1.4 in., 31-spline axles though <img src="/forums/images/graemlins/kewl.gif" alt="" />

I wish the manufacturers wouldn't always raise the R&P ratios whenever they give you a bigger motor. Isuzu Troopers went from 4.56 to 4.30 when they released their 3.5L in '98. I'm driving a '93 Trooper right now.

I live in Douglas, AZ, less than an hour away. Maybe you could give me a look at your Montero sometime. My Trooper is white with OME suspension, desert camo tire cover, and Nebraska front plate. If you see me, flag me down.

Later, Chris.

yeah anytime you are up in the area you are welcome to look at both of mine. I even wouldn't mind helping you look at one to give you my opinion of it before you buy it. finding a montero with a locker isn't that hard, just have to ask the dealer over the phone to check for the switch since most of them have no clue what a rear diff lock is. from 94-96 years, the SR model usually always had the rear diff lock option along with the 4.6 diff gears. 97 was a weird year b/c they changed the engine from DOHC to SOHC, kept the two different models: SR & LS, but changed the diff gears from 4.6 to 4.2. 97 SR's have the locker option. 98 & 99 monteros lost the model identifier SR & LS and they are just badged as monteros with different equipment. usually, if it has heated seats and head light washers, it has the locker option. adjustable electronic suspension also was an option for some and is very nice to have (my SR has them). let me know if you are in town or if you have questions; cell: 570-499-1402

later,
scottie

Also, I know this is a little bit ahead of time, but if you do in fact want to buy a montero, you don't have to get an older one b/c of the gears if you want to do this:

I have a front diff and rear diff (with locker) that I just took out of my SR to swap in 4.9 gears. I would offer both diffs to you for a few hundred which is cheap considering one of them would sell for 300 from a part yard. if you wanted to get serious with it, you can order the 4.90 ring and pinion sets for both front and rear for under 700 brand new from an online dealer and either swap them in the extra diffs by yourself or have a shop do it. then all you have to do is swap the diffs and since I swapped diffs in both my monteros now, I would help you do it if you wanted. I just wanted to offer that up to you so you don't feel cornered into getting a 94-96 year model just b/c of the 4.6 when you can swap in 4.90's. having the extra set of diffs is nice b/c while you are swapping the gears into the diffs, you don't have to have your montero on jackstands and not be able to use it as a daily driver. swapping the diffs you can do in a weekend if you have all the right parts and tools. I would recommend changing out CV boots while you have the front end tore apart. I did mine front end in two days and the rear end in one day.

To make sure I understand correctly...You have front and rear diffs with 4.2 gears and rear locker?

Do the '97-up have the 8" front ring gear that ARB makes an air locker for (RD110)?

I'm off work today so I'm going to cruise the car lots in Sierra Vista today. Should be there by one.

yes i have front and rear diffs with 4.2 gears in them currently completely at factory specs b/c they came straight out of my 97 SR and I did not take them apart at all. the rear is a factory locker. these diffs will swap directly into any montero between the years of 94-99 with 3.5L engine. the only thing different on the 94-96 monteros is the companion flange on the rear diff.

ARB makes front and rear lockers for the montero with the 3.5L engine. I put a front locker in my 97 SR it is a RD110. I am not sure of the part number for the rear locker from ARB, but I am pretty sure it exists. anyway, i would try to find a montero with factory locker, you won't pay any more or less at the car dealership, they don't even know what it is or if it has one.

just in case you want to do some research, here are the part numbers for the front and rear ring and pinion gear sets (4.90 ratio) that will go right in the Gen II or Gen II.5 monteros.

MR124860 Gear Kit+fr Diff $431.24

MR124858 Gear Kit+rr Diff $272.34
Subtotal: $703.58

Need a Spot
Scottie2113
I know this is an old thread.
I recently purchased a 98 with the adjustable shocks. How do you like yours for odd road use? I am trying to decide between aftermarket that matches the suspension kit (probably Iron,an) or ordering new mitsubishi shocks.
