dash rattle in 08 vert

[viperrrr]

My 08 coupe just developed a rattle that sounds like it is coming from the instrument cluster area. It seems to happen when you hit bumps in the pavement. I will hold the shifter and see if that helps

The dash is easy to take apart if needed, but you have to take off the shifter surround to get the bottom nut off of the face of the radio surround. also, all those pieces scratch easily. If you have to go into the dash, get the dealer to do it. If you want to do it yourself, ask somone to give you the pages from the service manual so you see all the screws and the sequence. I'd be happy to fax you, but, I'm traveling now and won't be home till Tuesday.

Thanks, I have the Tech Authority CD service manual, but it doesn't have a lot of detail in the pictures. I'll check your shifter theory and maybe get someone to do some listening to try and pinpoint the location better. I'll probably work on it this weekend some but I'm leary of pulling the center console bezel. If you get a chance when you get back I'd like to see your drawings for the bezel removals. Like you say if all else fails take it to the dealer. Thanks unclestu

My '08 has the same rattle - appeared after 1200 miles. It is the defroster vent. I haven't had the time to fix it. Can't be that difficult. Just fixed the same rattle in my Jetta diesel – two years to get to it – one hour to fix.

The shifter diesn't seem to be the problem. Rattle/noise noticeable from 5 mph up to 45. seems to get better after 50 mph. Also seems closest to the AC vents. Will check with the dealer to see what they think.

I had the defroster vent rattle on my 04, I can't believe they are still putting the same part in knowing that it was too long and rubbing up against the housing. It is indeed avery easy fix, you have to pop out the defroster vent, and shave off the bottom edge of the plastic and put it back in. The TSB number is 23-027-03 NOV 03

My 08 vert has/had a dash rattle that was intermittent but we seem to have isolated it as being the windshield defroster vent.

The service manual I have is a bit sketchy on how to remove the instrument bezel. Does any one have pics on how to get it apart and tools needed? Any help would be appreciated. Thanks.

I had the rattle also (first noticed after I put the top up), it drove me crazy. It was interment and seldom. I would hit the dash area by the defrost vent and it went away. When I took it in they said the fixed something in dash AA. We'll see as it wasn't making the noise then

I had thec same problem with my 08 coupe. It was making me crazy so I purchased TSB 23-027-03 for a 03-04 car from All DATA.Ifollowed the instructions and removed the deforster duct. I was a little surprised at what I found. The flange on the duct was already grinded at the factory. It was not done well. It was uneven. I inserted a grinding attachment on my dremel and sheared off additional material on the flange. I reinstalled the duct took the car for a test on a rough bumpy road and to my statisfaction the rattle was gone. It seems that the factory is using the same part as they did on the 03 cars and grinding it. If they did not take off enough material on the duct in your car you will have a rattle because the duct will touch the deforster grill.

Turned out that a bolt for the rear swaybar had come loose on teh rear passanger side. They retorqued it and the bumping noise is gone.

How did you remove the grille? Do I need a special tool? Thanks

There is actually a tool that the dealers use, (trim removal tool), I don't know exactly what it looks like. You should be able to get under it and lift it.

No sorry I dont. My local Viper Tech is the one who took care of it.
