Are you sure they are 18tpi and not 16tpi?

What are you using them for that keeps pulling them apart? Got pictures?

I know for fact that the QA-1 5/8x3/4 rod ends is stronger than the Grade 8 5/8 bolt that goes in the rod end.

A 3/4x3/4 rod end is weaker than a 5/8x3/4 due to less meat behind the bolt that goes through it.

I suggest having a thin bushing made to use 5/8x 3/4 where you have the 3/4x3/4

S&N sells good heims...been using them on my steering (full hydro) and pan-hard for years. They'll develop slop after a while but never had one break.

broke one today and i will be bringing spares my truck turned into a big pile of sh*t lucky i was going slow bushing it down and using grade 8 will probably work good center is very tight yet

82toyomud · May 1, 2007

What manufacturer are you using?

bigiron · May 1, 2007

using what psc sent no marks that identify that i can find

LiLBKO · May 1, 2007

go to a 7/8 rod end

82toyomud · May 1, 2007

I would try running rod-ends from a reputable manufacturer.. QA or Aurora

Why on earth would you do that? You claim that the 5/8" bolt is the weak point of the smaller heim so you think he should downgrade the larger heim to the smaller and weaker bolt?..The 5/8" rod end may be rated stronger than a 3/4" of one particular brand but that's not true for all brands.
I think you should post pictures of what exactly it is your doing with these heims to break them. I know from experience that a good quality 3/4" heim is stronger than a 60 steering knuckle.

bigiron · May 1, 2007

here are some pics i got a cheap end from tacoma screw and a spare plant to order some of them that are rated at 28,000 lbs

There is no arguement.... a 5/8 heim is stronger than a 3/4. There is less material on a 3/4 than a 5/8. Take a look some time

CrustyJeep · May 2, 2007

Well ****, you think maybe that off the hook offset has anything to do with it?

What brand heims are you breaking? Got pics of the carnage?

I call BS. All other things being equal the only difference is the size of the hole or stud in the middle and a 5/8" bolt is weaker than a compairible 3/4".

Looking at your pics I would fab something up to make it a double shear rather than a single.

bigiron · May 2, 2007

it is not breaking the bolts it is tearing the outside of the heim dont know how double shear would help in this case

Maybe nothing...

What kind of stearing stops you have in place to keep things from getting over-extended? Both on the Ram and the knuckle?

Is the knuckle stopping but the ram still have more travel?

this is what i think the problem is have my stops set on the knuckles so my axles just start touching at full lock but my cylinder has more travel how would i limit the hydro cylinder
