Suspension "Chirp"

Since winter is here, potholes and road-bound icebergs are everywhere here. Have been hearing a distinctive chirp in the front end when encountering either of these. Anybody else?

Thanks. The CJ makes all kinds of strange noises, but it's a CJ. This thing is new. Had me wondering.

I have the same jeep and the problem. I have brought it to my local jeep dealer twice and nothing. The first time they said they heard it but could not duplicate it, although on the write up they said that the couldn't hear it at all... then I had to bring it back and they had it for 4 days and could not figure it out. I'm not impressed. It has 8,000 miles on it and it sounds like a 150,000+ beater. I notice it more when there is moisture in the air. Very frustrating either way. Have you figure out anything on how to fix it?

Mine started when the snow and ice hit this year. When it dried up the chirp went away. Now when I go thru the car wash it will chirp for a day or two. It has something to do with the moisture. My dealer also could not find anything.

It's a Jeep not a Mercedes... It's gonna make a few squeaks and creaks. Start to question when it turns into knocks and grinding

I understand its a jeep. But when u buy it new, spend 27 grand, have it 7 months and not even had off road it should not due that. What gets me is the service techs say they have never heard of this and its on several forums!!

Try shooting some silicone lube spray in all the swaybar mount and endlink bushings. That was always the fix at the chevy dealer years ago.
I tore my link bushings up and they were clunking bad so I just removed the end links . My plan was to make a set of discos out of them but it drives real nice, so Im going to leave it discoed for a while.

Was wondering would squirting a protectant like "armor all" on the rubber bushing help? Eventually, they will wear out and have to replace. If you decide to swap them out for poly urethane you can squirt any kind if lube spray on them they won't break down like rubber but give you a stiffer ride. Companies also make impreginated urethane bushings not sure if it is available for the Lib. a friend of mine told me about them years ago. It is something you can look into. I think there is a company called "Just suspension". It's just my 2 cents.

When you get knee-deep in a situation, floor it.

My favorite protectant/lubricant is Fluid Film. It's all over everything under my Jeep. First learned of it from old VW and lawn maintenance forums.
