I am looking at my options for replacing my Gen I SWB, I really like the Gen II SR Monteros, but can't seem to find a link to my questions here, so If there are good answers here please let me know where to look.
I want to know about the differential on these trucks, how they work,Part time, fulltime, are they viscous, can I lock & unlock it in both hi & low? also, the rear locker, is it pneumatic? is there an option for installing a locker (part time) on the front?

Thanks, Your help will keep me away from the Range Rover Classics that I know will send me to the poor house.

I know more about the gen1 but I also own a gen2. The early SRs 92-93? have open diffs, not sure the locker was a option. The factory lockers are pneumatic. I dont know about locking in hi and low, I guess you could bypass the controll thing. On the larger front diffs, again, not sure the years, you can get an ARB. ARBs are also made for the rear, I have one in my 93SR. Others will jump in and fill in the gaps. I do know the big rear axles have a 9.25 in ring gear, 31 spline, 35mm shafts, that is fairly big.

With the 'Super Select' system found in the Gen2's you can engage the factory rear locker while in 4 High, locked center diff or 4 Low, locked center diff. You would have to fiddle with the wiring to have the rear locker engaged in 2 High. Normally I run in 2wd, but if the conditions are lousy I run in 4 High (essentially AWD with the center diff in viscous mode). In short, the Gen2 offers:

2wd High
4wd High (AWD)
4wd High Lock
4wd Low Lock
4wd Low Lock and rear locked (if you have the factory locker)

If you have an ARB I suppose you could lock it whenever you felt the need.

I've fiddled <img src="/forums/images/graemlins/smile.gif" alt="" /> Actually Augie fiddled and I re-fiddled.

Search for posts older than 4yrs by Augie with this topic's keywords if you want to do something like that.

[/quote]- Hmm, funny, I went from a '94 Range Rover Classic to my '92 Montero SR just because I WAS driven to the poor house by the RR <img src="/forums/images/graemlins/notooth.gif" alt="" /> So, I can really relate to that statement <img src="/forums/images/graemlins/wink.gif" alt="" />
All the above info seems to cover your questions, let us know if we left something out. PS. I believe an ARB kit for the front is finally available, but not sure which years it fits

ARB Model RD110

Well thank you all!
Yeah I am just coming to the conclusion that the RR will kill me financially. I already have a VW Vanagon Syncro that needs locker work & that's a grand & change an axle not to mention the manual drive disconnect that will set me back $1,500 & a Jeep SJ that will require $$$'s just to keep it from falling apart!

I have had nothing but reliability with my SWB and it has NEVER gotten me stuck on the trails. I have been thinking about a LWB gen1 or an early Trooper, but the gen II SR's just have so much going for them AT LESS THAN HALF THE COST OF AN FZJ 80!
It's funny, I was looking around here today & read a few articles about locker installation, and was drooling over the thought of drilling a small hole where the front diff goes on the dash indicator & adding a led behind there activated by the system when engaged!

Oh yeah, was the super select (and rear locker) available from 92 on up? and when did the 3.5 come out? I have read conflicting years on that one 93, 95 etc.
Thank you all,
Harry

Never got stuck, you are not trying hard enough. <img src="/forums/images/graemlins/kewl.gif" alt="" />

My 93 has "Active Track" with no rear locker. Well, no factory locker.

SR Gen2s could have a rear locker from '92 on, but it seems pretty rare on the earliest of the Gen 2s, not a popular option back then. The 3.5 liter for USA made its debut with the '94 SR Montero. I still have a 4 wheeling magazine from 1994 that ran a head to head comparision on the new 3.5 liter equipped Montero and a Range Rover Classic.
Hope this helps you out.

The Syncro is a cool rig. I'd love a Weekender, maybe a Euro front locker too...but they are pricey machines indeed.
