So you push your 1st gen offroad - what cracks next?

Manual hub axles are weaker than ADD axles 25 spline outer vs 26. Plus way more of a pita to swap.

I would sacrifice a cv though and just have the stub shafts with dust shields. That way if you bust a cv and you have a spare and it breaks you can install these to keep your diff full of fluid and wheel bearings held in. Just not have a shaft. So you loose 4wd but it'll get you home. Plus lighter and takes up less space. And you can carry 4(2 "axles") if the diff let's go and can get home that way vs pulling and gutting the diff. Which I've done @m3bassman was there and can attest it was not the funnest thing to do in the back country.

LBJ's aren't bad to have and bolts for big trips. I used to have an inner tie rod and outers in my osk. Usually if you're doing good maintenance the old ones make good OSK spares. Unless they are shot obviously.


Otherwise it's hard to have everything on hand. I've had other random things let go that you're just gonna have to limp home or leave it and come back. Like wheel bearings, rtt mounts, battery hold downs, alternators, diffs. Other things.


I also think who you're going with and where you're going and for how long all play into this.

 

I carry

2 CVs
1 manual hub (never broke one FWIW)
inner TRE / TRE tool (bent a few ITRE on 35s so far)
outer TREs
LBJs

 

You don't need a spare manual hub CV outer to make a stub out of... They don't need the CV installed to not fall apart

 

can confirm, wheeled multiple days and drove a couple hundred miles without one lol

 

I'm sure I carry too much and going through this will probably make me take some items out, but carrying most are worth the peace of mind so I can keep wheeling or make it home unassisted, and I am far from a good driver.

My kit includes:

LBJs
LBJ bolts
outer tie rods
inner tie rods
+3.5 tie rod extensions
manual hub jack shaft and housing
2 x spindle to uniball misalignments
rear diff drain plug
spare heim that works for steering and UCA
spare soft front brake line
spare steering rack D ring mount
spare steering rack D ring bushing
1-5 qt engine oil depending on the trip
1-4 qt gear oil depending on the trip
.5-1 qt brake fluid
sometimes spare spindles with wheel bearings and hubs etc.
2 each inner and outer CV cups - by far my most recommended item, I cut them down from spare CVs to swap in and run in 2wd if needed.

And some notes -
It is a 4Runner not a Tacoma
I have RCVs and if one of them brakes I likely have a bigger problem
I have heim inner tie rods but still carry stock inners and extensions as a spare
In the past 18 months I have used / broken:
4+ x outer tie rods
3 x jack shafts
2 x inner tie rods
2 x D ring bushings
1 x spindle
CV cups to get off trails in 2 or 3 wheel drive
engine oil since it leaks
gear oil replacing drained oil

thats not reason enough IMO to swap from ADD to manual hubs. I don't get why people do that. Weaker setup. PITA to swap. Can freeze over. No thanks.

 

Didn't say it was, although Wulf has pointed it out before, they usually break in the exact part that ADD axles do, the outer joint. Also they don't freeze if they're assembled right, if you have broken or missing seals they could but a properly maintained manual hub works pretty easily even in the negatives. I always just switched mine at the beginning of winter though.

 

I'd say it depends what your set up is. I've only ever carried a spare CV and tire, and I've never had to use either of them. But I've only been running 31s and 32s with a mild lift. IMO the best way to prevent breakages is to respect the practical limits of the vehicle - keep your CV angles modest and don't drive it like a rock-bouncer and you should be ok.

The people I see complaining that "IFS is junk!" are usually running 35s and a front locker. It was never designed for those kind of stresses; after all, Toyota has never offered a front locker except on the solid front axle set ups, not even the 100 series. And before anyone says 31s and 32s are useless - remember, they used to drove the Rubicon on 30s and 31s all the time back in the day before 40s became commonplace. Even 31s are big tires for these little trucks - especially if you have a single cab, you probably still have more clearance than a newer truck on 35s.

 

Ever seen any other trails that started to get heavy use... they get harder from the wear. Go run the Rubicon on 31s now.

 

It can be done. In fact I would be surprised if a stock trd first gen couldn't make it. Would it be in one piece at the end? Fuck no

 

Well a single cab on decent 31s could probably still do 95% of the trails out there. I think I posted this video before of some first gens on 33s running the Rubicon. They do break one CV around 6 minutes in (it looked like he was running a front locker and trying to turn up a rock step at the time), but other than that they seem to get a long just fine. A lot of people would probably call you crazy for attempting it with anything smaller than 35s.

I'm sure it could be done, I enjoyed watching the stock vehicle challenge, all they got was recovery gear and a winch... they used that winch a lot.

 

Really you read that here? Or have you been playing in the Jeep and Land Cruiser forums again?

 

Looks like a good time, you gonna come run it if I go and drag some others here too?

 

I chalked a lot of that up to no locker? I was specific about it being a trd truck lol we both know it makes a world of difference.

 

A locker would have been an immense help, but the low clearance was causing them to bottom and slide into worse positions to climb from too. Big tires or a truck you don't care about turning into a raisin are the two easiest options.

 

Not here, on the facebook groups mostly after they just threw on 35s and a drop-bracket lift and are shocked that they broke something. People don't usually seem to complain on this forum; they just patch it up and move on.

Maybe, I would like at least a rear locker for that kind of action though.

 

Wait a min the one on the right is @betterbuckleup (he's on 35s now BTW) and the other is Dan who's username is escaping me.

 

I thought you were set with your massive axle breaking 32s

 

Well, I do think my set up is more capable than most people would think with a competent driver. In fact, multiple people couldn't even believe I was driving it up Yankee Boy Basin and Kite Lake in Colorado. One guy said he'd never have though to take his Tacoma up there, and it's not even considered a hard trail. But a rear locker still helps immensely.
