Hotchkis rear sway bar

Heard a squeaking sound coming from the rear left and found my end link was rubbing against the spring. So, looked along the sway bar and it was snapped in the center!

Anyone know what would cause it to snap as it's the second time this has happened. I know sway bars reduce body roll, but this is my daily driver and not a track car and I don't believe it should be under such stress. Your thoughts are always appreciated.

Hotchkis replaced the first one under warranty back in '08 even though I had no proof of purchase - bought the car used with it on. Not sure if I'll be able to pull the same off this time, unless others have suggestions?

Cheers!

You need to grease the bushings 1-2x per year. If you don't, the same thing will keep happening. Luckily, the Hotchkis bushings have a grease fitting to make maintenance easy.

My guess would be that it was too tight (and maybe dry bushings too). Need to respect the Toyota/Lexus specified torque specs. For the rear sway bar, it's not that tight; 13 ft-lbs for the bushings/mounting brackets, 33 at the end link. But maybe 6 years is not too bad for a replacement? idk

^^ this! You must grease them like that or else they'll snap. These bars are hollow on the inside, therefor easier to snap when not greased properly. There's different threads on this if you google search it.

Make sure to use synthetic grease if you're using polyurethane/OE bushings. You don't want to use petroleum based grease if you have those types of bushings.

Looks like the consensus is they need to be greased often.

I got a reply from Hotchis - they requested pictures of the sway bar and my car. Hopefully they will warranty it.

Thanks everyone!
