What Tire Size Are You Running on Toy Diff's?

[6.72:1]

I have heard of 5.29s breaking to, but most of what I have heard has to do with the quality of setup, if they aren't set up good they will brake

I will probablely go to those eventually but the price right now can't be beat

Hey, I'd ride them out too. I concur with you on that though. If they are built right, they are sure to break. Driving style is involved too, but I am sure you aren't the one to be horseplaying....lol. aka MUSCLEsilver

well with a completely stock 22re not to many ponies there, we shall see how long they last, maybe I'll build up two 5.29 diffs for trail spares

Sounds like a plan. I would like to build my own differentials. What tools are involved and is it that difficult to do? I have a friend that is a Toyota mechanic that built mine, but I would like to learn. Any help would be great. Thanks.

If i went with new diffs again i would have to go with cryo'd 4.88's.  A lot stronger then 5.29's and still have good gearing.

[6.72:1]

But Hyena, I need absolute lowness in gearing!

[Hyena]

If it was a street driven truck then ya, 5.29s would be grand.  but when you start breaking out on the trail it is another story.  I would rather have strength then the added 20:1 or so crawl ratio.

I have cryo'd Yukon 5.29's aussie front and welded rear, but i haven't driven the truck yet

"to the floor", what tire size are you running though?

Looks like fat nasties....

i'm running 35s with 5.29s cable locker in the rear, lockrite in the front.
no probs so far.

   I'v got 38x15.50 sx's , welded front and rear diffs 4.37 gears, approx. 400hp 350/th350 duals by    I welded a ring on the bells of my stock birfs. it hurt my turning radiius a little but helped a lot very seldom do I break a birf now, Before this mod, I grenaded one every time I went out. this truck is a dedicated trail rig and I drive it pretty hard. (especially when I first built it and thought the skinny pedal would make it climb anything.

breakage list

birfs-too many to count
rear axle shafts-2
rear r&p-1
t-case input shaft-1 (from pure stupidity)
transmission case-1 (due to design flaw in my home brew crossmember)
U-joint-1

Agian I will stress that I am very hard on the truck and this kind of carnaige is not the norm

  I am putting a front 60 and rear 70 in my 91 runner and would recommend you do the same since you already have them.

what kind of cable locker?

[shad]

I am running Yukon 5.29's, treated longs, stock inner, axles aussie locker front, lockright rear and 35x12.50 BFG MT's.
No breakage yet in the last 10 trails. The only thing that has gone on me is my powersteering tensioner bearing so far.

I'm running 36x12.50 tsls up front,5.29's detroit ez locker.stock inners,Bellfields..not a problem so far up front I dog mine pretty good, I've had  this setup for about 4months...I have 37x13 boggers on the back Welded rear ,Ive broke 1 rear axle,ring and pinion and 1 cracked carrier

Friend is running 35" toyo's, 1 box with 4.0, locked front & rear.  Has broken 5 birfs in about as many months.   He believes the low gears and locked front are making quick junk of stock birfs.   Has broken 2 in dirt (the *v's* @ hollister) and 3 on rocks.

Also on his last break, the detroit was up front.  Toasted the left side of the locker when the birf let go.   Has not broken any axles yet.

He's got some marfields now and lincoln locked both ends.  He's gonna see what breaks this weekend.


As for me.  The stock axles seem to hold up really really well to stock gearing and 33"s.

OK, I will give you some input.  I am brand new to these forums ... GOOD STUFF HERE!

I have an 88 S-10 Blazer with a 350-350 tranny and 205 case.  It weighs in at about 4,700 lbs.  I have Toy axles and LOVE them!  On year 2 I broke a L & R Berfield (almost at the exact same time) and then immediately put in Long's 30 spline super set. It has a lock right,  I have NEVER broke anything on the F-end since.  The rear is an 88 (Lincoln locker) and in 4 yrs of wheeling this thing hard on 36 inch TSL's I have only ripped the carrier apart, only because I was to cheap to buy a spool.  If I had done that, I am 100% sure I would have never broke anything in the rear.

In addition to this, I have done just about everything you can think of to abuse these axles!  Reverse to 1st, neutral drops, banging gears in the sand, mud at 5000 RPM's, Power braking it on dry pavement, 4 wheel drive smoke show trying to pull my buddies Ford out of a 20 ft ditch   .... I have done it all and these things just keep hanging on!  I have done a fair amount of rock crawling, nothing huge and serious, just average.  I love them, god bless those Japanese engineers!!  :-)

Hell.

[Northern Runner]

Damn, with abuse like that they must be strong......
I am cheap too, I like the welded rear diff in my truck. Like you say though should be a spool.
I don't think I would ever go to a locker in the rear.

truck sound crazy.....welcome to the board.....you gotta post pics of that thing somewhere !

[Stewy]

Yeah sure ... I would be glad to.  It is not a "rock crawler" or what most would call a "serious trail rig" but it is VERY functional and dependable!  I love it when I can just get in it and go and not worry about stuff.  I am now 36 and built it when I was 30 ... then it was fun to work on and now .... not so much anymore but once in awhile is fine.

I will try and get some pic's up soon.  Thanks for the hospitality!

that thing really sounds awesome wish i had a second blazer to do that to... you definitely gotta post some pics of this thing

[Stewy]

I will try to do so tonight or this weekend at the latest.  Our last trip out (this last weekend) one of the guys got some awesome pic's and put them on a disk.  it will be easy for me to post them.  I probably should post them on a new thread and not detour to much from what this thread originally started as.
