In addition to a few other things (cup holder lid wouldn't reliably open, rocking driver's seat, loose window moulding) I've recently taken my Mo into the dealer for work on a loud metallic rattle from the rear suspension.

It's clearly audible over mildly uneven road textures at lower speeds with the windows down. With the windows up you can't hear it at all.

I reproduced the problem for the Nissan tech, she heard it no doubt, and "fixed" it by adjusting my e-brake cable as tight at possible (it's much tighter now, can't depress the peddle nearly as far as before).

This DID help, but did not completely fix the issue, it still makes noise over speed bumps and rougher roads.

Anybody see this before? Any possible solutions?

Sounds like they applied this fix:

Yup, I agree, exactly. The question I guess is SHOULD the Murano still rattle a bit over speedbumps? Anybody else fight this issue and get anywhere with Nissan?

I have had it addressed twice, still rattles... I was in the parking lot today when another one went by, rattling as it passed. I felt fortunate that mine was not as loud as thiers... It makes the car seem cheap when you hear that as it goes by...

There is a TSB for the parking brake rattling. Go to the dealer and have them look at it. They fixed mine after 5 attempts. It's most likely the parking brake rattling.

 

[MightyMo]

Dookie, do you mean the TSB Dmako linked to above or something else?

 

[Dookie]

Yeah thats it! I didnt even see that link...

I have the same rattle, and sure enough if I apply the parking brake just one click on the pdal and the rattle is COMPLETELY gone...haven't brought in to be fixed yet, but it can't be that hard...

The TSB tells you to do the parking brake adjustment in the Service Manual, which says...

ADJUSTMENT
To perform adjustment operations, remove tire from the vehicle with power tool. [I think they mean rear wheels...]
1. Insert a deep socket wrench to rotate adjusting nut and loosen the cable sufficiently. Then, return the pedal to the free height. [This is at the brake pedal, under the dash.]
2. Using wheel nuts, fix the disc to the hub and prevent it from tilting.
3. Remove adjusting hole plug installed on the disc rotor. Using a screwdriver, turn the adjuster as shown in the figure until the disc rotor is locked. After locking, turn the adjuster in the opposite direction by 5 or 6 notches.
4. Rotate the disc rotor to make sure there is no drag. Install the adjusting hole plug.
5. Adjust cable as follows:
a. Operate pedal 10 or more times with a force of 294 N (30 kg, 66 lb).
b. Rotate adjusting nut with deep socket to adjust pedal stroke.
NOTE:
Do not reuse the adjusting nut after removing it.
c. When parking brake pedal is operated with a force of 196 N (20 kg, 44 lb), make sure the stroke is within the specified number of notches. (Check it by listening and counting the ratchet clicks.)
d. With the pedal completely returned, make sure there is no drag on the rear brake.

Pedal stroke : 3 to 4 notches

I'm having this problem too. At first they couldn't reproduce the sound but then I took the tech for a drive so he hears it now. I've had the noise since I bought it (2004 awd SL) 2 months ago. I mentioned this TSB but he quickly nodded "no" as if this didn't sound the same. I'm taking it back in for the actual service/repair on the 24th .. we'll see how that goes.
Depressing the EB didn't reduce the noise either, BTW ...

I'm aware of 2 different issues in the back. One is the parking brake adjustment, however, I have heard to a much much lesser extent of something (was it a sleeve rubbing?) on a shock, causing a noise.

I have the parking brake rattle, which I'll either do myself or have done on the next service visit.

I'm bringing this old post back because I need help...

I recently purchased a pre-owned 2003 Nissan Murano SL with everything but the navigation. I've been wanting this ride for a long time.

Well after a week or two of driving, I noticed that mine also has this same problem with the rattling from the rear. Its odd because almost every post I've found online about this seems to be dated about 2 years. I know the 03 and 04 Murano's have had this problem. I'm just wondering if this problem existed from the beginning and the original owners never noticed it or it didn't bother them. It is undetectable with the windows up.

I took it into the local Nissan dealer and provided them with all the info I obtained online including the tsb. They "tightened the brake cable" and although the noise is not as audible over smaller bumps, it is still there over large bumps. "Clank, Clank, Clank, Clank"(I drive up a ramp into a parking garage every day at work and the noise annoys the crap out of me.) The service advisor basically told me that the cable is as tight as it gets and there is not much they can do other than replace it and see if that helps.

My question is, and it might be a dumb one... There are more components to the parking brake system other than the cable right? Could it be that the technician is tightening the cable but not adjusting the rest of the components correctly? I'm asking this seriously as I don't in any way claim to be a mechanic... I just feel that this problem is so minor that the service guys should be able to fix this no problem especially if its supposed to be a known problem for the muranos.

This sound alone makes me wish I never made the trade. I had an 01 Montero Sport which was not nearly as nice as the Nissan but definitely did not have any loud bangs every time I hit a speedbump or went up a parking garage ramp... I bought it pre-owned simply b/c I could not afford a brand new one. The dealer is trying to give me the old used car guilt trip when it has nothing to do with it. This is faulty manufacturing from nissan. The worst thing about it is that the dealer is basically saying, "this is the best we can do" and not giving me any alternatives. If something needs to be replaced, let me know... I'm frustrated and...

Annoyed,

EliteOne

Any Suggestions?

 

[Enforcer]

Well yeah there are other components in the parking brake system that can be rattling but lets make sure its the brakes first. Does the noise go away when you apply slight pressure to the brakes or parking brake?

 

[eliteone]

Yeah, it goes away when I slightly press the parking brake and go over the same bumps... Thats how I know it has to be the same problem listed above...

 

[njjoe]

eliteone-

I say "to hell with the dealer". Do you know a local mechanic who has a reputation for doing great work? If so, take your MO to him, explain the situation and I'll bet you a beer he will correct it. He may have to resort to a cable-tie or use a non-Nissan clamp, but I would bet he will have more success than the Nissan boys (probably cheaper too).

Ok, it's one of those parts on the diagram then. I doubt it's the actual cable lines going to there. Ok folks, bets down, round and round she goes, where she stops, nobody knows .

I would bet it's the shoes and that adjustment part #2 can take up the slack. Been a while since I did that on a car but you can get that too tight, you just want to take up the slack. THe tool we used to use was called a brake "spoon" but you can use a screwdriver there is usually a slot under neath with a rubber plug. And if I remember right it's just backwards of what you think. Lemme check the SM...
