How do you regrease the bushings?

my car is making a squeaking going over speed bumps, I think its more noticeable in colder temps.

I installed hotchkis sways and swift springs just over a year ago.

The hotchkis bushing brackets have a zerk fitting on it. Use a grease gun that attaches to the fitting and squeeze in silicone grease. Don't use water-base grease as it will wear off with moisture.

I would loosen up the brackets to allow grease to move in. Otherwise you won't get anything in.

Mine ended up being the bushings, bad after 24,000 miles. It took two different dealers to figure it out as well. First it was the actual strut, they replaced it and the noise was still there. Apparently I had a bad strut. Not sure about anyone else but this is my 3rd G and probably my last. I've had more problems, replacements, squeaks and rattles for any Infiniti I have ever owned. Also have an FX35 10 years old, 150k miles and its more sound than my 11' G37S! Go figure. Good luck with your problem, I would make sure they replace the bushings!

Had same issue but my bushing went out on my camber arms. SPC was nice enough to send brand new arms for free, fixed the issue.

To the OP..... Let the hooker outta the trunk.

I'm glad this thread is back up so I can share my thoughts. My car was experiencing a squishy sound over bumps/dips and more noticeable during the cold (as mentioned on the first page). When I took my car into Infiniti for an oil change, I let the service adviser know about the noises I was having. Later found out it had nothing to do with the shocks or stock suspension.

A week later I brought my car to Corner3Garage (Laguna Hills) for the noise. It was determined that my bushings were completely dry. They took off the brackets and bushings, cleaned all the debris that was stuck on and regreased it. Problem gone.

Notes:
-Pumping in grease from the zerk fitting is completely USELESS. This method only puts a little grease in between the bracket and bushing. What you really need is for the grease to sit in between the bar and bushing.
-The silicone grease is more likely to loosen up and drip away during the hot summer weather.
-At 28K, didn't need to replace Hotchkis bushing, as they were still in the same shape as day one. *I almost purchased the rebuild kit thinking my bushings were deformed*

Anyone ever find out the solution for this? I added grease to my hotchkis swaybars but I still hear the squeaky noise? My friend mentioned it could be the wheel bearing and possibly the bushings, but some guy above also noted it was the strut assembly. Not sure what to do as both as equally expensive, but I'd probably do it myself.

My noise is more so kinda when turning / going slow and not necessarily over bumps

Could be tie-rod ends or steering knuckle. You hear it when going slowly because wind and tire noise mask it at higher speeds.
