I've recently become fixated on the idea on selling my 4runner and building something nicer and more comfortable like a GX470, but watching that reminds me how fun it'd be to keep the 4runner and go with my original plan of going dual cases and dual lockers...

You could always go FZJ80 if you wanted a luxo wheeler. I've got a friend with one on 2 inches of lift and 40's. Outside of just being huge, it wheels really well. One ton rear axle and a high pinion 8 inch front diff with monster knuckes and birfs is awesome from the factory.

Too old and too high mileage for too much money around my area. It's an older platform than the 3rd gen 4runner and is also really underpowered. I would like to get away from the era of vehicles where rust and the constant need for small repairs is going to be present. I've loved my 4runner, but with 19 years and nearly 400,000km on the odo, it does need more attention. And don't shoot me for saying this, but I'd rather have IFS than a solid front axle. I have yet to reach the limits of my 3rd gen's IFS and this would still be my daily driver. Unless we're talking trailer rigs and really extreme stuff, solid front axles are very over rated IMO. In my area at least, so many people seem to think they need a solid front axle for camping and wheeling trails that a stock truck with a rear locker and sliders could make it through...

I agree. I have a fully built 3gen pickup SAS, air lockers, duals, 37s. I can run the same trail with my 3gen 4runner ifs with 1 rear locker. Plus my 4runner is a dd more comfortably

No way a single locked, single cased, IFS truck keeps up with a dual locked, dual cased, solid axle truck. Been there and done both. Once you get into big rocks the IFS doesn't hang. The SA truck doesn't ride as nice or turn as precicely on the highway as a trade off.
IFS totally has a place though as a solid trail riding rig. You can run 80% of the trails a swapped rig can and have a great time. I can't stand the guys that say you have to swap in tons and 40's to wheel anything.
I would go to dual case way before solid axle swapping though. It's a complete game changer if you are 5 speed.

Agreed. When the trail difficulty reaches a certain level, factory IFS offerings will be at such a severe disadvantage that it doesn't make economic sense to keep repairing it to run that level of trail.
All depends on where you wheel.....many of the "buggy only" trails out here most definitely do require 1Ts and at least a 39" tire if you want to run them without breaking constantly.
I've built a couple of SFAs that rode nicer on the street than they did when they were IFS and flat smoked IFS on the fire roads to the trails...so it can be done; you just have to really dial in the suspension.
As a side note, even factory SFA can ride relatively well. IMO, the '99 WJ Grand rode every bit as good on road as my '99 T4R.

Anyone have problem running 4.7 up front with chain case? I run 4.7 in the rear of my crawler no problem. But inchworm doesn't recommend jw? Just thoughs

4.7 in front of the stock chain chase is essentially the "Tacobox".
The Inchworm recommendation has to do with running two gear driven cases.....you don't want the 4.7 in the front case in that instance. ***EDIT*** And apparently it's not recommended in front of a chain driven case either. See Jaysen's post below.****

I don't doubt you on that either. But inchworm post this on their site.

Lowrange Offroad had/has (can't find it now) an article on it....they (are partners with Inchworm) said it's proven itself to be fine.
Let me see if I can find it....Well, I stand corrected.
I can't seem to find it anywhere. Thought it might be in my email list since they send out a newsletter, but that goes to my junk folder and only goes back to Dec. 27th.
Best thing to do, IMO....is call Lowrange and ask their reasoning. If you don't mind letting us know what you find out, I'd appreciate it as not being able to find the article is driving me crazy. (I know, short trip, lol).

I'll swing by Marlin Crawler on moday and talk to them. Since they are here in Fresno! Will update you guys.

Funny I just remember one of Marlin old friend 86 2gen turbo pickup ran a 4.7 front case with a 2.28 rear case for years without problems. Maybe it's a miss understanding somewhere..
