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

take it apart and shim it internally

I also nootice your steering arms are very short, shorter than even a stock located arm. this will put extreme pressure on steering parts and the knuckles. If you made longer arms you may not need to shim the ram. If you had arms that lined up with the stock holes you would use a 9" double ended ram from lock to lock. go about a inch shorter and a 8" ram would work. I use a 9" ram and run a grade 8 bolt through the top steering arm down through the stock hole. this creates a double sheer.

I bet this is a big part of the problem.

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".

ROD END SPECS
4130 Chromoly Teflon Kevlar male rod end.
Thread Size: 3/4-16 RH
Ball Bore: .750
Ball Width: .875
Centerline Length: 2.875
Thread Length: 1.750
Load Capacity: 28,081

Ball Bore: .625

Centerline Length: 2.875
Thread Length: 1.750
Load Capacity: 40,572

That is a 12,491 difference

You can look at the specs of any manufacturer and the results will be the same. Even call your local rock buggy builders,

It's a simple fact that the 3/4 will break the heim, while the 5/8 wont.

Also look up the specs of the grade 8 bolts. there is no use to run a 3/4" bolt that far exceeds the heim

Before calling Bull **** , make a fewcalls or do some reasearch.

I one thought the 34/x3/4 was stronger, then I got educated

A grade 8 5/8 bolt is 36,524....with a 40,475 heim

A grade 8 3/4 bolt is 53,408...with a 28,081 heim

Do the math and toss in some common sense and figure which heim will fail before the bolt.

Class is over:fawkdancesmiley:

Like I said that's one brand. Not all brands are the same.
You have no class, how could it be over.:haha: :flipoff:

Show me one brand that has a stonger 3/4x3/4 than a 3/4x5/8 in the same product line.They do not exsist. there is just not enough meat left around the hiem body when you stuff a 3/4 bolt in.

Sorry you think different, but your opinion might be passing on mis-information to others that have issues they need fixed. You can even call some of the local guys that build these buggies for a living. Or do a little reasearch ( I have)

I never said 3/4 x 5/8 but here is a couple(5 different examples) pages of info from just one quick search. I guess class is back in huh?

Now lets get back to the original question to you. Why on earth would you take a 3/4 rod end and bush it to 5/8? Is the bushing going to make the 3/4 bearing stronger some how?

briejer · May 3, 2007

This all could be a misunderstanding of terms. When I refer to a 3/4x5/8 heim I mean the threaded shaft is 3/4 and the hole is 5/8. On a 3/4x3/4 both the threaded shaft and the hole are 3/4. On a heim that is 3/4x3/4 the ball and race are smaller than the 5/8 ball and that makes them weaker.

My thought of putting a bushing in the 3/4 hole is so he can use a 3/4x5/8 heim.....the bushing being put in the 3/4 steering arm.

The guy is having problems with the 3/4x3/4 heims breaking, not the bolt.

All the "class", "school",or other degrading comments, and fancy flip offs are not called for, I apologize for them. It's to easy to turn into an internet bad ass.....and there is nothing bad about me....i'm just an ass.

Don't take things personal and get all wishy washy on me Robin, it's just the internet.
Only reason I even argue the subject is the same as you I don't like to see bad tech info in threads like this so guys will read it and build maybe not the best thing. Not a big deal.:cheer:
