Suspension bushing squeaking problem

GuyT · Mar 19, 2014

Ever since day one I have this squeaking noise problem coming from the suspension bushing (back wheel, passenger side).

Took the PM to the dealer, they put some lubricant (Honey Goo) that solved the problem for about 50 miles.

So, I used some WD40. It solved the problem...for 300 miles, now the squeaking is back.

Anyone had the problem and solved it for good???

Dealer ordered a new bushing, we'll see what happens.

GrassHopper · Mar 19, 2014

Mine squeaks really bad! Dealer attempted 3 times to fix the issue, unsuccessfully. They replaced the shocks, which didn't help at all. They re greased the leaf bushings in the rear which fixed the problem for about 120 miles. Eventually they said that this is a cargo van and its suppose to sound like that, which I laughed at.

I called the chrysler and opened up a case number with them, got a case manager assigned to my case. I am suppose to bring it back on the 26th and have the chrysler technician look at it, chrysler is supposedly going to send out they're technician that day...

I told them bottom line is if the problem isn't fixed I want another vehicle. or 7k off this one. Because It didn't make that noise when I bought it, and I have multiple buddies who own promasters and they somehow don't experience this problem at all, so it isn't fair for me to pay the same price for a bunk ride.

We're suppose to so see what's gonna happen on the 26th, if they cant fix that then we'll suppose to work something out with chrysle.

I also have other issues with the vehicle, like cruize control shifting down to 5th gear when going up the hill, which is normal. Although it doesnt shift back up to 6 when up the hill and going on a completely flat road.

Hi GrassHooper, thanks for your feedback.

I don't think its a design error, everybody would have the same problem. Also, I get the noise comes from one side only, so it looks to me that the problem is simply a bad batch of bushings.

If I was a mechanics, I would switch the rear bushings just to see if the noise switches sides. I bet it would.

Anyways, I don't know if you mentioned it to the guys at Chrysler, but it would be nice if you mentioned that you are not the only one out there with the problem. If they can acknowledge that there is a problem, they will find the cure.

Hmmm, mine suddenly stopped squeaking at 'round the 600 mile mark. Maybe the bushings, leafs, shocks need to "break in"? Whatever it was has settled down considerably. Decided to sub-carpet & carpet instead of going with a wood based floor. Quieter & cheaper...

Good for you!

Found this thread on a Jeep forum:

That led me to find this product:

Will give it a try if dealer doesn't fix the problem. But it sure makes them look bad. "Yeah, it squeaks, but we don't have a clue why".

might just be a bad bushing.

superlube makes some great stuff but they have a huge variety of greases. makes it kind of hard to choose

It's when they don't know why and don't follow up with a "we're looking into it" or something along those lines that gets me wondering.

Mine is still squeaking. I've had it in twice and they've only fixed it for about 10-20 miles. I think its the bushings too, but also I think my factory installed wood floor is making noise too. If anyone gets any answers, I would love to know.

At first, I thought it was the floor too, but just to convince you that it's ok, make someone jump inside and from outside, you'll clearly hear where it's coming from.

I think the best we can do is go to the dealer and tell them that there is quite a few people out there having the same problem, so tell them to bring the problem to a higher level, just like GrassHopper did.

I mean, I am sure that Fiat-Chrysler wants to make a success out of the PM, so if I was them, I would try to silent all those squeakers on forums.

GrassHopper · Mar 21, 2014

I get squeaking from both sides. Although significantly more from rear right.

It's pretty weird. I hauled a load to Seattle from Chicago and 60% driving it sounded like **** and 40% it didn't make any noise....Of course its back to squeaking again...

Yes I sure did mention that to them. They even asked to provide them with the web address for the social board.

On another hand side the dealer told me that they're also having a lot of problems with 2014 grand cheerokey rear end suspensions..

I'm sure they're aware that something went wrong during production on quite few of those.

Can't wait till monday..because if they don't have the solution to this. I am hiring an attorney who's going to lemon this car and get me a brand new one.

Emphasize the the fact the brakes are squeaking too. Federal lemon law is not a given, even if you've been without the vehicle for over a month or had it in three times for the same issue. There is language in it about safety related repairs. Brake issues are easier to win on. I used a specialist atty who worked on a set contingency fee based on the value of the vehicle. Worked for me.

Yes the breaks squeak from day one as well. Chrysler did admit they used to hard pads and rotors, or something like that. They're suppose to be releasing new pads and replace the squeaky ones under warranty.

The lemon law also would apply if the defect that cannot be repaired, decreases the value of your car.

My brakes squeak too, but I was under the impression that they all squeaked. So it's only a few of us that have the brakes squeaking problem?

Well, my brakes don't squeak.

Thanks, zwarte, I'll look into that, too.

Squeaks = character, it's Italian get used to it. Interior parts will fall off that's fine. Just be glad we're not talking EGR valves and rust as in the sprinter forum.

My brakes squeak too but only when they are cold. No suspension noise.

Thanks, 30 Ounce.

If others have brake and/or suspension please mention it, I will use that info to put pressure on Chrysler via my dealer.
