The dealer installed front and rear Stillen sway bars for me this past summer. I got them to put it on the "middle" stiffness setting. Car drove wonderfully for a few months, then creaking/squeaking began to develop in the rear of the car. It is quite loud and annoying now, and you can hear it easily inside or outside of the car. The noise occurs when going over bumps or uneven pavement, making turns, etc. Basically whenever the rear suspension moves. I have started doing research and I am reading alot about the compression rods making this noise, but that seems to be an issue only on the front suspension. Is that correct? This is definitely coming from the rear. Since the dealer installed the sway bars and this noise appeared not so long after, do I have a bargaining chip to get them to fix this for free (no longer under warranty)? Any ideas?

 

The swaybar bushings likely just need to be greased

 

So is the compression rod issue limited to only the front suspension?

 

yes as there are no compression rods in the rear.

Quick test. Spray some WD40 onto the bushing areas adn see if it stops. If yes = bushings need to be greased

 

I forgot. . .do the bushings have grease fittings? Or better yet, how do you "grease" the fittings?

 

my hotchkis are starting to make this noise..or have been for a little while..sounds like a popping sound though on mine....

 

If you have the fittings, you simply attach a grease gun and pump.

If not, you have to pull the bushing and slather it in sticky water resistant grease and reinstall.

 

i have had mine for over 2 years and have not heard anything like this. When i installed mine i greased the bushings very good.

 

Check your end links.

 

Based on some quick research online, the Stillen set does not have any grease fittings. So what is the easiest/quickest way to grease the bushings? Do I need to remove the entire rear bar?

 

The joys of the squeaking and creeking....

 

The bushings are undoubtly split right? So no I don't think you have to remove the bar. Just remove the bracket and slip the bushing off. Lube the unholy hell out of it with marine style bearing grease or the stuff that should have come with your bars and reinstall.

 

Would it be a good idea to go ahead and switch to polyurethane if I am pulling the bushings out anyway? If so, where can I purchase just the bushings?

 

You are correct, the bushings are split so just remove the brackets and pull the bushings out. Vigorously coat the inside of the bushing and re-install. Prothane makes a great grease that I've been using.

Check your end links while you're greasing the bushings.

 

Summit sells the Prothane bushings but there are a number of aftermarket polyurethane bushings available. Check this thread for bushing options.
