Author Topic: Toyota Axle Strength (Read 6380 times)

1Bad4Runner · « **on:** Oct 20, 2005, 08:25:48 PM »

I was just wondering what a rear Toyota axle can handle for horsepower and if the V6 is any stronger than the 4cyl?

I am planning on putting them behind a Chevy 350 with an Auto tranny with 36" tires.

the front would be ok for a while,but i would look at changing the rear diff asap.my first engine conversion in the hilux was a 307 chev(running 35" bfg's)didnt do alot of off road work,only got about 6 months out of back diff.

honestly if i were you i wouldnt even mess with toyota axles, i would go to a junk yard and find some rusted out nasty K5 and yank the 60's out of it. what are you getting the motor out of?

v6 is stronger than the 4cyl, at least the 3rd is, but if you're gonna be putting a lot of power to them, its not gonna matter much anyway. I'd just go with some 60s, if you can. If you have any kind of lead foot, its not gonna be a matter of if it breaks, but when it breaks, and in this case sooner rather than later

I have a 60 and 70 in my yard, but I plan on flipping them upside down, now for high pinion... but the run a rear engine. I was told that a Ford 9" would be the best, but I think they are very pricey.

Let me know what you guys think.

i see them hold up to 40/42 " tall tires with longs all the time.. arb or open ofcourse but tat is with a 4cyl..

1Bad4Runner · « **Reply #6 on:** Oct 21, 2005, 02:20:33 PM »

Yea, that is why I am nervous of using a Toyota axle, I can't seem to find many Ford 9" axles around here, I was thinking maybe flipping a D44 also.

I guess we all have our own driving styles .... my Toy rear end has held up very well 36" TSL's and a 350. I have NEVER

broken an axle or a R&P and yes I have done about all you can do to in abusing it.

Reverse to first, power breaking on wet and dry pavement, the tranny has a very aggressive shift kit and when it goes from 2nd to drive at 5000 R's.....

BAM!!!!! 4yrs running now with only a carrier to show for carnage.

When you say your gonna flip the axle upside down for high pinion use, which way would your axles then turn?

??

doh i totally misred i thought you were talking about front and rear not just rear.. the rears will hold up no problemo welded/spooled whatever.. just dont run a detrioit.

S-10 Stewy · « **Reply #9 on:** Oct 22, 2005, 09:21:15 AM »

The only reason my rear carrier split in two was because I was to cheap to buy a spool so I welded er up and it put enough strain on the carrier to literally rip it apart over time.

I am sure mine is not the first to have this happen to.

Ya just gotta love those little axles .... tuff stuff!!!!

you must have welded it wrong or somthing.. out of the shopi work at we have over 100 welded toyota diffs out with no breakages.. some behind 350's and big tires and what not.. some out there are over 5 years old

Get cromo's for the rear and be done with it.

Thanks for the info Stewy... the motor will be in the truck backwards

and no its not for high pinion.

Also, I just for a set of Ford 9" axles for $100 CAD, it that worth it?... I guess they aren't all that pricey. and they should also hold up, right?

I'm just asking because they have the pinion that comes out of the 3rd and I have an article on how to make the oiler work for a flipped axle.

Iron Clad, the first time the gears were welded together ... @ 100%!!!! That lasted for almost a year until the welds failed

and then we used a stick welder (took it to a reputable shop and said... do this) and this held for almost 3 yrs before it failed.

What happened was: as you looked at the back of the 3rd member next to the ring gear, the carrier literally separated from the twisting action or stress being put on it, it pulled it apart. Some wheeling buddies said they had never seen anything like it before, myself included. The most funny thing about it was when it finally broke, the whole diff started working again just like a regular open diff, yeah it made some popping sounds but worked just like normal. I/we "never" welded to the carrier itself, only the gears.

Welded it wrong?

. I just chalk it up to: abuse, design flaw, poor casting .... who knows. If I still have it I should post a pic of it so we can all give our .02 cents worth.

I have a 9 inch myself that is in the early stages of being modified for my S-10. I like em!!! Dana 60's are nice, can't argue with that but there is a reason why guys run the 9 inch behind high HP funny cars, street rods, blown alcohol injected big blocks. THEY ARE TUFF and LIGHT!!! $Beer Chug\'n$

No guys ... I am not down playing your Dana 60"s ....

but the 9 inch with 35 spline axles is a very good rear end!

Go to: www.highnine.com and see what they have to say.

Very interesting site Stewy, prices are very high... but they have very nice stuff.

S-10 Stewy · « **Reply #17 on:** Oct 25, 2005, 02:57:46 PM »

I am one of those guys that says: "You just can't argue with the facts" and that site has some hardcore facts about the 9inch that can not be disbuted. Spendy??? Yep ... hey, who ever said this sport was cheap??

?

After seeing some of the avatrs and other pics on this forum, I quickly learned that mine is probably one of the cheapest. 4 wheeling is a BLAST!!!

! but it cost $$$$ to do it. $Beer Chug\'n$

i think your ring and pinion will go before your shafts on the toy axle im running a guttless 20r and 35s and i broke a stock 4:38 ring and pinion last weekend

1Bad4Runner · « **Reply #20 on:** Oct 27, 2005, 06:55:38 PM »

Thats shitty, I hope not to break anything, but that is very unlikely.

I hope it works out, but the front axle is going to be very complex... I have to make independant suspension out of a 9 inch.

S-10 Stewy · « **Reply #21 on:** Oct 27, 2005, 07:44:50 PM »

The stock (factory) R/P almost always break. The after market gears are fairly stronger.

1Bad4Runner · « **Reply #22 on:** Oct 28, 2005, 09:19:25 PM »

Good, maybe that means my 5.29's will last awhile then

S-10 Stewy · « **Reply #23 on:** Oct 30, 2005, 08:21:30 PM »

My guess is that they will. Apparently the factory R&P's just don't hold up. I have heard that from more then just a few.

those seem to blow up a lot, and they only have 8 pinion teeth. i had one go a year ago just driving down the road. can't help that it's 26 years old too
