Author Topic: OH NO, THE STEERING KNUCKLE STUDS ARE STRIPPED!!!! (Read 8239 times)

TurtleTappers91 · « **on:** Mar 27, 2007, 07:16:09 PM »

OK, I know this sort of thing happens alot on Hi-steer equipped toyotas, but rather than BREAKING

My studs are PULLING out, stretching the threads in the knuckle or somthing. I went to re-torque the studs as I do about every 3K miles, and the inner most 2 studs just turn in the knucle. Now with only 2 studs tight, I am fearing for my life, as it is D.D.

It is obvious I have some work ahead of me, but I would like to PREVENT

This from happening again if possible. Oh yeah, and no Trail Gear parts are ever to be on my truck, so those fancy six shooters are just not an option. Trying to heli-coil the knuckles seems like a waste of time......It would not hold up...
Has anyone drilled and tapped for larger studs? Seems like you'd have to drill out the steering arms too, and that could compromise the whole cone washer system. Who has a fix that will last?

heli-coils are stronger than original threads....

Will heli-coils be a good fix?? less likely to pull out?? anyone done it?

drill out to dana 44 studs or get some new knuckles and get ARP studs.

O.K. I searched for ARP knuckle studs on yahoo untill I found Front Range Off Road,

This place has the studs and I can get replacement used knucles for $30 each!!!!! $Beer Chug\'n$ Sounds like my best option so far. Thanks for that little bit of info.

thats what i did when i broke all my knuckle studs. it was a good deal.

If I had to go through the hassle of replacing knuckles and studs I would just get the 6 stud knuckles and ARP stud sets now. You can run the 6 studs with 4 stud steering arms until you get the money for 6 stud arms if it is an issue.

Hyena · « **Reply #8 on:** Mar 27, 2007, 09:10:23 PM »

for that much money i would just go 60.

TurtleTappers91 · « **Reply #9 on:** Mar 27, 2007, 09:28:58 PM »

If you find me someone other thain T.G. making the 6 studs I'd love to know about it. Wabfab sells them but I'm pretty sure they are the TRAIL GEAR just sold by the wabbit.
The 6 stud knuckles made by Trail Gear are not up to marlin's standards or specs, so why would I run them on my rig which runs almost all Marlin parts?? I will buy them if Marlin ever does decide to make sell them, though.

TurtleTappers91 · « **Reply #10 on:** Mar 27, 2007, 10:08:25 PM »

Maybe I'll weld the steering arms onto the knucles.

I can still remove the knuckles by removing the bottom cap's, and I can still re-shim the lower side up If need be

yup.

RustyToy · « **Reply #11 on:** Mar 28, 2007, 09:19:22 PM »

let me know if that works.. it could be a new trend.

RRMike · « **Reply #12 on:** Mar 30, 2007, 10:16:28 AM »

x2

I've never thought of taking the bottom cap off. No cone washers to screw with. Might suck to still be attached to the tie rod though and try keeping the knuckle out of the way while changing axles/birfs. Maybe not

This is an old ad that has already been redone. Unfortunately our new ad did not make this month's Crawl magazine. We do not carry, support, advise, suggest, or recommend anyone to use the 6 stud knuckle that is available on the market today. The reason is that it is based on a three-year-old design that we did not approve the manufacture to make due to design concerns. I do not have permission to comment any further on this subject, so please do not ask.

You must be talking D60 knuckle conversion on the toyota axle? Dosent Marlin run something like this on his pickup? It seems to me that a full D60 conversion would be pretty expensive to set up comparably to my built up Toy axle. (4.88, ARB, Alloys,Marfs.,etc.) And then to match width at the rear axle probably looking at a rear swap as well. Thats a BIG list o' parts. D60 outers on the toy axle sounds really cool and I want MORE INFO ON THIS!!!!!!!!!!!!!!

what crawl magazine I didn't know there was a magazine. Is it like a catologue or magazine? I need to buy some parts but I am not sure how to do it? I feel really dumb for asking.

dont think its marlin doing the advertising... marlin has stated they want nothing to do with those inferior construction/stolen idea part that trail gear sells. marlin does not sell 6 stud arms or knuckles

as far as the arp studs, im sure people have broken them, but its a lot more rare..... if you manage to break those, its time for the d44 stud mod or a d60

i am talking about a full 60. your front axle isn't as strong as a stock 60.

along with this, the hybrid d60 knuckles on the yota axle is hella $$$$$$$ more than setting up the d60

TurtleTappers91 · « **Reply #21 on:** Apr 01, 2007, 07:33:37 PM »

About how much wider is a dana 60 front axle (wheel mounting surface, not with wheels/tires) than a toyota front axle ? What I'm wondering is can you keep the toyota rear axle without the front being too wide. Maybe the 60 can be narrowed a little? I'm sure there is alot involved in doing this swap but I have never researched the details. maybe its time to.

If it is really so strong, It is a worthwhile upgrade...

jimbo74 · « **Reply #22 on:** Apr 01, 2007, 07:37:36 PM »

get a 86+ rear yota axle and toss some wheel spacers on it... problem solved

Hyena · « **Reply #23 on:** Apr 01, 2007, 08:38:06 PM »

ya, or you can have it cut down.

kneedownnate · « **Reply #24 on:** Apr 01, 2007, 08:59:57 PM »

That's the route I'd like to go, narrow a 60 front to about the same width as an 86+ rear, maybe a hair wider. My friend's dad built a v8 bug and narrowed his own 9" and it's been good for a couple/few years, just not sure if he's willing to do a front

This is a great idea! the tires would not stick out too far. you know, laws and stuff. Could be the perfect mod for the bullet proof off road truck that is still street legal. Thats sort of what I'm trying to do...

It says march/april 07. It was march when I posted. It is still april. Doesn't that make it a recent ad? Sure it is a 3 year old design. but are based on a design from the 60's but with 2 holes added and 2 bosses for a caliper. that would be a 47 yr old design that took us 46 yrs to decide that it needed a little work.

If you can't talk about the design flaws that make it weak isn't the 4x4 world going to suffer? Your company was the one helping with the design that is out now. not necessarily the ones that put it for sale, but had to do with the design thats out. are peoples wheels going to fall off?

I was under the impression that a toyota axle with longs is as strong as a stock dana 60. Is this not true?
