Default Help - Roll bar links keep going. Any ideas?

Hi all.
I have a 2003 PT 2ltr.
The two front anti-roll bar links (its like a bolt with a white plastic bush) keep breaking. One of these will go about every 4 to 6 weeks!
Has anyone else had this problem or does anyone else know what underlying problem could be causing this?

Many thanks

i would guess it's one of these 5 things:

1 swaybar is bent

2 swaybar links installed incorrectly(bushings backwards / bolts inserted from bottom instead of the top / metal spacer missing)

3 nuts not tightened enough

4 nuts installed too tight

5 inferior quality parts / wrong link kit. mine had a small ~3/8" center metal spacer. maybe yours are too long and it's bending the bolt?

do you have a pic of a broken one or know where they are breaking?

Another possible "installed incorrectly" factor:
Everything should be tightened with the car sitting on the tires, the car at ride height.

From the shop manual:
"INSTALLATION
NOTE: Before stabilizer bar installation, inspect the cushions and links for excessive wear, cracks, damage and distortion. Replace any pieces failing inspection.
(1) If removed, install the stabilizer bar cushions on the stabilizer bar utilizing the slit in each cushion. Position the cushions at each end of the bars straight beam, just before it begins to curve. NOTE: Before installing the stabilizer bar, make sure the bar is not upside-down. The stabilizer bar must be installed with the curve on the outboard ends of the bar facing downward to clear the control arms once fully installed.
(2) First, place the stabilizer bar in position on the front suspension crossmember. The slits in each cushion must point toward the front of the vehicle and sit directly on top of the raised beads formed into the stamping on the crossmember. Next, install the cushion retainers, matching the raised beads formed into the cushion retainers to the grooves formed into the cushions. Install the cushion retainer bolts, but do not completely tighten them at this time.
(3) Clean the threads of the stabilizer bar link bolts, then apply Mopart Lock And Seal or equivalent to the threads.
(4) Install both stabilizer bar links back on vehicle. Start each stabilizer bar link bolt with bushing from the bottom, through the stabilizer bar, inner link bushings, lower control arm, and into the upper retainer/nut and bushing. Do not fully tighten the link assemblies at this time.
(5) Lower the vehicle.
NOTE: It may be necessary to put the vehicle on a
platform hoist or alignment rack to gain access to the stabilizer bar mounting bolts with the vehicle at curb height.
(6) Tighten each stabilizer bar link
by holding the upper retainer/nut with a wrench and turning the link bolt. Tighten each link bolt to a torque of 28
Nm (250 in. lbs.).
(7) Tighten the stabilizer bar cushion retainer bolts to a torque of 28 Nm (250 in. lbs.).

You of course know that these are installed while hanging in the air on the assembly line.

The bolts are breaking at the top of the threaded part. The bolt is smooth where it goes through the bush and then narrows where it is threaded. It always snaps on the narrower threaded part.

i would thread the nut onto the bolt with it off the car and mark the threads where the nut is when there is appx 1/16" thread still showing before the smooth part. it sounds like you're cranking them on too tight and bottoming the nut out onto the shaft.

if you didn't lose any parts you might get some grade 8 bolts from the hardware store so you know they are decent quality bolts

I think that there has to be something else wrong. I have never seen one break unless it was rusted to where the diameter was so small it broke off. It must be binding against something. A picture would tell us volumes.

i tend to tighten stuff like a gorilla and i've broken many bolts where the thread meets the shank. usually exhaust studs for me. the nut can't twist on any farther and it stresses/twists the steel when you try. the first thread does most of the work. if it's breaking at the "runout" area, this is almost certainly the cause.

Notes on Nuts and Bolts edit: just read the "bolt terms" part, not the whole thing.(it's short)

im big on the "K.I.S.S" method of doing things. IMO the simplest solution is usually the correct one.

Ya, breaking it on the install. I only tighten these till the bushings start to squash a little.
