Default Squeaking when going over speed bumps.

My rear suspension is making a squeaky annoying sound whenever I go over speedbumps or just moderate dips. I only have around 38k miles on my 07' STi.

strut clunk is a clunk, not a squeak. The squeak could be as simple as swaybar bushings needing a little grease. Try that first, its a whole lot cheaper. White lithium grease works well.

lithium grease is oil based, it will deteriorate rubber try silicone lube

^^ won't deteriorate the rubber at a fast enough rate to matter. Considering the majority of stock bushings are made with some kind of self-lubricating rubber and have no lubrication from the factory, any amount of lubrication helps with the friction and noises.


If you want some really nice grease check out the energy suspension formula 5. Works great and its very sticky so it stays in place. Also has a teflon additive.

Mine squeaks over speed bumps when the suspension is cold. i.e. it squeaks going out, but doesn't coming back. It is different than the clunk. That I have under control with grease on the rear struts. The squeak is on both ends. I think it's the shock oil. In real cold weather I've had non performance cars do the same thing.

Now that it is getting colder out, my rear swaybar is creaking over bumps and driveways. I had it greased last year by a local mechanic when he fixed all of the issues found during the PPI. However, I have never done it myself.

I was planning to buy some of the Energy Bushing Lube (mentioned above)...but since I haven't done this before, I was looking for some advice:

Do I need to put the car in the air (remove load from the suspension) in order to remove and re-lube the swaybar bushings (front and rear)? Or can I simply crawl under there with the car parked and remove and re-lube?

Thanks in advance!

Jack

You want the front or rear to be equally loaded as in don't jack just 1 corner up. You can probably do the rear without getting the car in the ground. With the front, you may have to remove the subframe to get to the d-mount nuts. If you have a 12mm swivel head gear wrench or a ujoint socket, you might not have to. Just get the d-mount off and slide the bushing a bit till you can get it off the bar, clean it, regrease and reinstall.

The rear should be cake. No subframe to remove, just loosen the two 12mm fasteners on each d-mount, remove the bushing, clean, grease, install (don't strip these nuts/bolts, it can be easy).

For the rear, you probably don't need to get the car in the air, but the front you probably do.
