SAS rear sway bar - bolts let go!

I was driving the car tonight, and heard a loud clang. Thought I ran over something. Didn't hear it again, so I went on my way. Arrived home and inspected around the suspension pieces in the rear and found the left rear sway bar bolts to be completely gone. Inspected the right side and found them to still be tight, and not corroded, as best I could tell.

So I reattached the bar on the left side with the original hardware pieces that came with the stock bar. Is there any reason to go out and get heavier hardware, or is the stock enough?

I suppose the hardware from Genuine Saab would work too.

This bar has been on without incident since, oh, probably 2003 and 75,000 miles ago. Lesson learned is to re-check the bolt torque periodically!

haha, the left side bolts on my GS 22 arb came loose last friday even WITH loctite after only 5mo/6000mi on the car!

i hand-tightened but they still came off in the last 3 miles before home. luckily the right side was tight, so when i got home i moved a bolt to the left side and went to the parts store...

I'll have to check my GS rear sway.


When I installed it, I got tired of holding it up with one arm, while tightening the nuts with my other. My arm got tired holding it at that weird angle (and it is a heavy gauge bar). So I used Zip ties to loosely hold it in place so I just had to rotate it and tighten the nuts.

I never removed the zip ties, so if the nuts/bolts work their way loose, the zip ties will prevent the bar from falling off, and it will just swing off the axel.

You can see the zip ties here:

Should not be a problem if you use good grade-8 bolts 3/8" UNC x 1.5" long with a nylock nut and hardened washers.

You need to re-torque it after it beds in. This happens because the mounting tabs on the frame are almost always rusty and the washers bed into the powdercoat just a little.


JK I don't understand how the bolts could come loose. Those nylock nuts wont loosen.

Also tighter is not always better.. You want just enough preload to hold the part nicely while leaving enough of the bolts strength to handle the working loads.

Amish - cable ties are still second to the pile of toilet paper.. I forget who that was.

My GS bar is still as snug as the day I put it on there. I second what Nick says about the nylock nuts, those should not come loose at all.

Tito were you out on 146th street by the clay terrace mall in carmel around 8:30 tonight. I thought I saw your white 9-3.

It's allways good measure to check these things at every oil change or at least evey 15k miles, or Maybe I'm just paranoid
