I am this close to buying my first locker going to get an aussie and all along I thought I was going to put one in the rear but I heard today that it might be better to put it in the front I have a 1987 with the gay IFS and because of this i heard with the very limited travel of the IFS it would be better to put it up front because it is more likely for one of the tires to come off the ground while going over rocks and what not but even though I do, do some rocks I love to play in the mud to so what would be better for that. maybe some day I will have both front and rear but untill I can afford that i am only going to run one so I would love youre input.  |

Rear. If no other reason than you might want to do a SAS some day, and then you'd be stuck w/an IFS locker to get rid of.

Not to disagree with the rear locker preference, but if not running rocks, is the front ifs/cv's really that weak? I have put my truck through a substantial amount of mud without any problems(open diff). I really can't justify a solid axle conversion($$$). It just seems strange that there are so many front 7.5/ifs locker/slip options if the system overall is that weak.
If and when I lock my front, I will probably go through and rebuilt everything out to in anyway.
Understandably, I couldn't see locking a dana 28, That's weak. But the toy ifs seems quite capable. It's just not for crawling rocks.
Anyway..... I do agree with rear first.

Rear, because in any rear wheel drive vehicle, the rears do the majority of the work, even once you flip it into 4WD. On an incline the majority of the weight shifts to the rear. Furthermore, if this is your daily driver, you'll be miserable with a non-selectable locker in the front, ie you can't steer for shiat -  |

That and the weakass steering makes for a pretty weak system in the rocks. Add a locker and look out. Of course it can depend how you wheel it as well. Stick to mud and sand and you will probably be okay. Ive wheel with people that ran them in the front on IFS, but they werent into rocks. But if you are "git"en after it as they say you will break shiat. But as IFS systems go the torsion bar toyota front is actually pretty tough. In countries where the solid axle was just recently discountined its the torsion bar system they are using, instead of the coilover because of the strength advantage. |

Sean, when you "popped" your cv's, was this a "stranded" type of thing or was the vehicle "limp home" capable? I've always considered having a spare set on hand, but I have been lazy and not gone to the junkyard a gotten another set for backups. Are they reasonable to repair on the trail? Or are they a well lit garage, cold beer, full set of tools project?

I never had to trail change one, just unlocked the hubs, but they are an easy swap. I just bought rebuilt shafts from the local parts place.

Nice, thanks for the reply. Just wondered how tall the boots should be for the sh*t I'm going to get myself into.
Obviously, you bought reman cv shafts. I just wonder about the quality vs a (myself) rebuilt stock or junkyard piece. I've rebuilt one(non-toy) and it wasn't too bad. But with Toyota quality and tolerences, I wonder if it is feasible or possible to rebuild one to OEM spec???

also the front gears are weak. my buddy blew the front up with 33s and just driving up on a small tracked tractor.

That is really disapointing. I've always assumed Toyota, even IFS was as strong as std half ton(american).
But, anything will beak given the chance.

if i remember right the front gears on the IFS are as small or smaller then dana 30 gears. at least dana 30 has a reverse cut gear.

def rear, Everytime I go wheeling in the rocks and flexy terrain, the first to lift a wheel is the rear end...guess cause the rear is so stiff and no load is on it, I like 94cnytoy's quote "anything will break given the chance". In "general...." the yota IFS is solid up to 33"s. It all depends on how and where you give it the juice and if you got the steering turned.

Also in my experience gears dont go unless 1)you gain alot of hp 2)they are neglected and the oil goes bad or gets low 3)The gears are installed improperly or faulty gear set. If people on this board are running 44's and IFS I think it can certainly handle anything smaller than 35's. If you abuse anything it will break...eventually. I was on the trail last year and a yota on 31's busted a birfield. Go figure...I had 33's and IFS on the same trail and didnt break anything. I didnt see how the driver busted the birfield but I can only assume he had the steering on the steering stops and was flooring and hopping.

Just my two cents, but I would agree with putting it in the back. You want the locker on the wheels with the most grip. Since grip is a function of friction which is affected by mass, having it in the back is preferable when going up hill as the majority of the weight will shift to the back, just like everyone else has said. Let's face it...you don't need a locker going downhill when the weight is on the front....
As for CV strength, I managed to break my first one finally in December. I had abused them plenty and the boot was torn....it was only a matter of time. I was pulling a gal out of the ditch (she didn't even know how to engage the 4WD in her Envoy) on 1/2 an inch of ice as this was a rather nasty rain storm in 20 degree weather. Long story short, I spun long enough and fast enough to melt through the ice. When my little 34's hit that asphalt, it was all over with. Interestingly enough, it was the shaft the broke first and the joint that grenaded only after it was crappie flopping around.......

The first time wasnt so easy... i broke 4 harbour freight extensions and one craftsman... it was a bi**h... had to use a cheater bar... air compressor wouldnt budge it... i am hoping if there is 2nd time it will be much easier... its definately not a trail fix... |
