Thread: Diagnosis of noises needed

I have, and had, 2 of those noises.

No 1: Pretty sure my "wind noise" is coming from ill fitting, or worn, rubber seals around the doors. At some point my drivers side front and rear doors have been extensively repaired (and not that well either!), so mis-alignment of hinges could be the issue on mine too. But my Hankook muddies and radio help supress that!

No 2: Can't help, sorry!

No 3: Slight ticking is common when the exhaust flange gasket bolts come loose (where the down pipes attach to the rest of the system - 3 bolt connection). Usually just a quick nip-up should suffice, or you can add a spring washer to stop the nut from slipping. That's what I did with mine and seems to be good for some time now.

Cheers again,

the tick/ping...

CHECK YOUR DOUBLE CARDEN JOINT NOW.

yes, its in capitals for a reason, I also normally do it in RED and under line it...

like this..

CHECK YOUR DOUBLE CARDEN JOINT NOW.

the wind noise is probably a vortex on the door seal at the back of the door, try closing the door on a length of packing box cardboard and take it for a drive, it can also be the trim on the top of the windshield

no idea on the growling, that one I'd have to hear.

1. Loose exterior A pillar trim?

2. Td5 ? It's not the centrifugal filter winding down, is it?

1. If it's like mine, you will be able to slide a piece of paper between the door window frame and the seal. If so, you can place a length of say 5mm flex behind the seal to raise it slightly for a quick fix. Or for a permanent fix, pull the door trim off, loosen the window frame, and re-tighten with the frame angled a little more toward the seal.
Worked for me anyway.
2. Not sure, but doesn't the ABS modulator normally have a fit every now and again.
3. Well, Blknight has that one covered.

Cheers,

1. As the others have said

2. Posibly the SLS compresor, mounted on the chassis under the front passenger seat area.

3. As said but check the Cardin Joint($$$ if it "lets go") first then head to the exhaust.

Whilst I certainly don't disagree with Blknight's comments, just check those flanges first.
Those carden joints are a HUGE issue. But when I noticed my ticking and posted up here a while back now, I went into panic mode over the carden joint issue due to the amount of people telling me it was the CJ's. What I hadn't mentioned on that post was that that particular issue had been "fixed" less than 2 weeks prior.

Another forumite pointed me in the direction of the flange bolts. Got under and had a look with a socket set, and they were loose. Tightened up and hey presto no more ticking, for a while anyway. They came loose again and thats when the spring washers were installed. Prob over a year ago now, and no ticking since.

Like I say, I am in NO WAY bagging Blknight's comments, he has offered me many useful and correct diagnosees(?) in the past, but I'd just check those bolts before having a coronary!!

Cheers,

As regards the wind noise, check that the bailey channel in the rear doors that the window slides up and down in hasn't slid down with the window, I have had 3 D2's do this all of them rear doors, 1 RH side 2 LH side. all had dropped by up to 25mm in the top corner where it meets the top seal. This creates a whistle like non existent roof racks at times. I just pull it up with thin nose pliers, it'll stay there for quite some time before needing it done again usually.
I agree check exhaust flanges if V8, and DOUBLE CARDAN JOINT is a priority to inspect carefully AS THE NOISE APPEARS ON AND OFF THE THROTTLE.
The SLS compressor will growl 3 or 4 times occasionally after switch off if parked on slopes as it will try and level the vehicle slightly.

it goes without saying that you're checking the whole shaft, not just the DC itself.

any disjointery on that particular bit of spinny steel is going to be at best un-nerving and at worst will leave you with you with that, "why does my wallet hurt so badly and where did all my fun money go?" feeling along with the sudden realization that your car is now an insurance write off.
