Rear Sway Bar Maintenance

[Champale]

OP - did you figure this out? My 2020 with only 2k miles has been making squeaking noises over some bumps (but not all), seems like from both sides. Notice it usually after driving the car for at least 10 minutes. Thought it might be my exhaust but I have gone over it several times and nothing is loose or even close to touching anything else. I can yank and shake the exhaust pretty hard and it doesn't make any noise so I am beginning to think it's in the suspension.

I did and it was not the sway bar. It was the rear seat latch. I applied some pink grease (same grease I had used on sway bar ironically) on the U shaped hook where the folding rear seat latches on and the noise was gone.

How funny ok thank you for replying. My car doesn't have a back seat so I will have to figure it out.

The funny story is that my 19'GT350 start making squawky noise too going slow over uneven roads. I refused to accept the fact that one year car have problem with any of suspension parts. So, I start with simplest I can think of where this sound can be coming from. My first guess was rear seats. But it wasn't. Than I inspect trunk area. The black rubber seal which goes around the trunk and trunk door rubbing against each other is what made that noise. I put some silicon lube around the rubber seal and the noise disappeared. Let me know if it works for you.

Hey lenFeb - well that seems like it's worth a shot! Did you pull the rubber seal up and put it underneath or did you just put it on the outside of the seal where it contacts the trunklid?

Just put it on the outside where it contacts trunk lid.

Super, thank you.

I had this issue with my Ford Racing rear swaybars. They didn't ask for any grease during the installation process, but after a few months they began squeaking. Stopped immediately once I put some silicone grease on those bushings.

Very good info - thank you, Mavisky!

My car was made the week the factory reopened after the Covid lockdown and I have had a few weird minor issues from day one (like an O2 sensor that was loose from Day 1) and am wondering if something in the suspension wasn't snugged down correctly or could use some grease. I am going to jack the car up, pull the undertrays off, and just doublecheck everything in the next few days.

I appreciate the feedback, guys!
