so on my way to the AX saturday i noticed a "clunk" sound from the frontend, like i had lost something.
i had this happen before, bolt came lose on the swaybar droplink, so i thought that was it ... when i get to the AX site and change tires, i see the droplink hanging all weird so i take a closer look and the lower hime joint has broken. the thread just snapped off the joint. i then continue to change the tire on the other side and it's exactly the same! (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) both hime joints broke in the exact same location. that seems too odd to be coincidence. i must have hit something *really* hard for that to happen, but i can't remember running over any bad potholes etc. anyone else had problems before?

I see. Well that sucks.
I had already pretty much decided that the RS was getting this bar, but I haven't done much pricing. Who has the best prices on these? |

all about the same; if you really want to support Ira buy direct. he won't undercut his distributors with lower pricing but he won't have to pay their cut either.
i will be running a different bar in the 911 (it a preference thing...) but i will DEFINITELY run Tarett droplinks. they're the only ones who "get it" that 10mm hardware is required. there is no question that the Tarett bar is a much nicer part than the WeltMeister it is frequently compared against. |

alright, let me say first that i really apprechiate Ira's offer of replacing the parts for free, (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)
but i will have to kindly decline. obviously, whatever happend, it had nothing to do with the material or quality or layout of his swaybar and i feel if i took him up on his offer, i'd be cheating him out of some well deserved money. so, whatever parts i'm going to need, i'll be more than happy to pay for! (gee, what a concept ...) (IMG:http://www.914world.com/bbs2/html/emoticons/cool.gif) now here are the blurry pics ... --------------------------------------------- |

drivers side:
note how the hime joint is stuck all the way towards the outside of the car. it was so much in bind that i could move it back by hand ... (IMG:http://www.914world.com/bbs2/uploads/post-11-1123180833.jpg) this is how it's supposed to line up with the car on the ground ... (IMG:http://www.914world.com/bbs2/uploads/post-11-1123180874.jpg) closeup. NOTE: how the U-Tab is bend to the left but the joint broke at full tilt to the right! i am guessing the tab bend to the left when the car was on the lift with the weight of the wheels and the joint hitting the top of the tab. then, when i hit whatever pothole it must have been, the joint moved all the way to the right under compression and snapped ...

pass side:
same here, hime joint was stuck towards the outside of the car ... (IMG:http://www.914world.com/bbs2/uploads/post-11-1123181005.jpg) nuther, showing how it's supposed to line up ... (IMG:http://www.914world.com/bbs2/uploads/post-11-1123181023.jpg) closeup, again, the actual u-tab is bend the other way ... (IMG:http://www.914world.com/bbs2/uploads/post-11-1123181040.jpg) one more, more sharp this time ... (IMG:http://www.914world.com/bbs2/uploads/post-11-1123181061.jpg) |

I wonder if moving the link out .25" to .375" would help any?
I would be a little concerned of "twisting" the arm with the link out too far. Attached image(s)

so it looks like all i need is two lower hime-joints with the set screws, one left and one right thread ...
also, how important is it to keep the "arm" of the sway bar level with the ground (i heard that is the optimal position) because if i make my droplinks *longer* it'll take out a few degrees in angle and i might clear the u-tabs better ... (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif) oh, and the bushings had marks and were deformed on the top on both sides, so the joints were definately in a bind. but that could have happened with the car on the lift. as you can see from the pics, under normal load, the joint were nicely centered on the tabs ...

if anything i need to move it *IN* and not out. with the lower joint pointing outward when it snapped, that means the upper part was too far *out* at full compression ...

I've been running Ira's bar in the front of my car for a couple years....set on full soft.
The venue I AX on is god awful rough, but have had zero problems. If I ever get an LSD, I'll spring for his rear bar....if I have any money left (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) Hay Andy: Them pics ain't bad.

just to clarify ... when in first installed this bar i had the u-tabs in the stock location AND stock rotation. on full soft, the hime joints would hit the top of the u-tab at just minor compression/decompression ... when i got my new a-arms i opted for rotating the u-tabs 90 deg. because it seems to give me more free play around normal load situations and only hit on full decompression (on the lift) (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) Andy |

Pics of the actual failure site may be able to tell us if it went all at once, or if it fatigued into failure over repeated cycles. Not sure that is valuable info any more, because it seems pretty obvious what happened...

hmmm, this is interesting ... it almost looks as if the joints are made out of two materials, the outside (the thread) is still nice and shiny while the inside is rusted ... but it hasn't rained here in weeks and that just happened 2 weeks ago! btw. my camera *sucks* for closeups ...

Maybe you bent the tabs on a full decompression (go off any jumps lately?) and then broke the heim joints on full compression. (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif)

Got me thinking that when I went to put the mounts on the A-arms for my race car someone (forget who) told me to align the bolt holes fore-aft and not crossways as Andy has his. Wonder if that makes any difference? I agree about the upper mount moving out slightly with a spacer since the heim joint looks like it is bolted solid against the arm?

looking at it again, no need for a spacer, just flip the arm (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) Andy, can you cut part of the remaining thread to get a fresh cross section? |

huh? moving the upper mount outward would make it even worse ... the lower joint broke off while it was pointing outward. it must have been in a hell of a bind as it was stuck in that position because it had deformed the spacers ... moving the upper mount outward will simply result in the same thing happening much earlier with much less compression. you guys gotta need to take some geometry classes ...

my second statement was "if" you had to move it in that direction..... |
