Broken Strut Tower Bolt. Safety Issue?
Posted 01 September 2003 - 03:21 PM
Is it safe to drive around for a few thousand miles with one of the bolts broken off? I don't think there is any way to repair it short of removing the strut and replacing the strut mount.
By the way, to what torque should the nuts on the strut tower be tightened? The Haynes manual is unclear on this point.

The spec only says to torque to 14 ft/lbs......or that's what everyone says.
You don't need to tighten them super tight.

On the other hand, the bolts are that small because they don't have to work very hard, most of the time the car's weight holds the top of the strut against the tower. Only when the suspension expands (deep holes/jacking up) do the bolts really come into play. Oh, and they stop the strut support rotating along with the steering - the McPherson set-up relies on rotation about the strut "axle" for steering movement.
If it were my car, I would flatbed it home or to the mechanic and fix it. I'd hate to have the front suspension play a prank on me during a brake/turn-in/throttle open/throttle close/oversteer manouvre

You've convinced me that I should replace the strut mount as soon as possible, but I'm not convinced that the broken bolt creates such a safety hazard that the car shouldn't be driven. (As one of the posts mentions, the greatest force is upwards against the strut tower, and the bolts likely don't play much role in controlling that). I'll just make certain not to engage in any high performance driving in the interim.
I figure if I go through the effort (or the expense of having someone else do it) of replacing the strut mount, I should replace the strut. And if I replace the RH front strut, I might as well replace all four (and their mounts and dust boots).

and yes, if you do replace the strut on the one....might as well do all the rest.

Thanks alot, the attached image is the dimension I'm looking for on the strut.
Also, is that measurment on the KYB the same. And what will the KYB's do to your ride height?
Thanks for your help.
