I just removed a blown front end out of a '99 100 series (not mine) and it was the ring & pinion that failed not the 2 pinion diff. FWIW
As for 100 MPG in town I get 14-15 regularly with 285's on 87 octane

The gas mileage on the 100 seems fairly impressive compared to the 80. Although I'm curious if lower gears would improve or reduce mileage on an 80 with taller tires, such as 33s.
As far as the blown diffs, It's interesting that we don't hear too much about blown 80 front diffs (except for extreme cases) when they supposedly use the same size ring gear. Of course, everything else should be completely different as the 80 diff and housing is an entirely different animal.
I wonder if the issue with the 100 is the housing and it somehow flexes more there is weakness in the system.
I'm sure this has been discussed at length, but I don't get on the 100 forums often.

Slee blames some diff failures to A-Trac

Well, Mark (MLachica) was right about the rear locker. I originally was set on finding a rig with a OEM rear locker, but since reading about this week front diff possibly needing an upgrade, i am not so set on the rear locker!
I think after doing more research that i am possibly going to go with a 00+
Plus, the color combo i am searching for is "Thundercloud" Exterior with a dark grey interior!

I think they're talking about front diff failures, I haven't heard of the rears failing...Boston Mangler said:Well, Mark (MLachica) was right about the rear locker.

Makes sense. As I'm sure you are aware most people on 'Mud advocate the '00+ and if you can afford it the '03+ with the 5spd auto. There is a VERY long thread in the 100 section on this topic. From what I have read it basically comes down to the decision between having the rear locker or having TRAC. Assuming the same level of mods, it seems ARB lockers would eventually find their way onto the rig. Therefore, you eventually end up with either just lockers('99) or TRAC and lockers('00+). In either case eliminating the front diff issue.
My biggest concern is if I keep a 100 for 10-15 years, are the electronics (TRAC/VSC) going to cause potential problems down the road? Not having a lot of experience with them, I can't honestly answer this question. I do realize though that there is definitely an increase in the safety factor with those gizmos.
As I get closer to bringing children into this world I'm am looking at the 100's. I'm interested to see what you will decide. I'm also moving back to SD in the AUG/SEP time frame, so we'll have to compare notes! Anyone for the San Diego Brewing Company again??

Toyota has an excellent record when it comes to the electronics, so I wouldn't be worried about them 10-15 years from now at all.
It's not like GM or Ford, where modulars and computers and relays going out are a given thing every few years.
There are computers and electronics from Toyotas from 20 years ago that are still running just fine. So long as the part was designed and made in Japan (and it should be on the Land Cruiser) you should be good to go.
Personally, I'd be more concerned about where gas prices are going to be in 10-15 years and whether any of us will even be able to afford to drive them.

Yes, i know, but the 98-99 that have the REAR locker, also have the weaker 2pinion front diff! Hmmmm, decisions!

Yes, but it is family/safety based. I am interested in safety, but also interested in the mechanically differences in the years, not seeing much mentioning of that!

Probably not into my rig! I am not a big fan of ARB air lockers, i think they are too problematic, and they require too much maintenence for their price. I want the ultimate in reliability and dont want to be messing with solenoids or O-rings in the middle of no where. Yes, i am sure tons of you have them with zero problems, but i have been offroading a long time and see LOTS of different people with lots of different rigs, having issues with them!
Thats just my .02, lets not get off topic here!

Yes, this is also one of my biggest concerns. The more sophisticated the vehicles become, the harder they are to dianosis and the more expensive the failing parts are!

I am set on a 100 series for sure, which year and such still isnt decided, i guess i should go rear up on mud!

Yeah, true. From everything i read, its a wash for me.
Might stick to the 98-99 with the rear locker, as i dont see myself EVER needing a front locker and dont ever see myself doing hard enough wheeling to blow a front diff!
My 80 was built to the hilt and i only engaged the front locker once in a blue moon to make sure it didnt seize!
