Summary Description:

SUBJECT PERTAINS TO EXCESSIVE MOVEMENT AND NOISE FROM THE DASHBOARD. *TT

Hey mike,

where did you get this TSB? I have been having trouble with my s70 and the noises are unbearable. DId you take it to the dealer to get it fixed? WHat do they do?

Thanks.tim

I got the TSB from www.nhtsa.org and called my dealer to find out about it. Wasn't easy to find since it's NOT a TSB but a "tech note".

Anyway, the gist of the thing is that the dash movement is caused by broken dash support brackets (I have no idea where they are). The claim from Volvo is that if there's work on the dash and the technician overtightens the nuts that hold the dash to the brackets, that the brackets can break. I don't know if I ever had work on my dash before I got the car (volvo select), but the noise started when I went over a speed bump, as if something "gave".

When I brought it in for service, they put "insulation" in the dash (don't know how). This fixed it for about a month. Now it's back with a vengence. Coming from the middle of the dash, where it meets that other plastic piece that runs along the bottom of the windshield.

Spraying with silicone helps short time.

The "TSB" is to replace the brackets if they are broken, otherwise tighen the nuts to 6 ft/lbs. Wish I knew where they were.

Thanks to G. Vicari at Toyota/Volvo of Keene, NH.

Mike,

Her's my guess. There are four screws that secure the facia panel inside the car. Their are also 4 bolts that secure the top of that part to the firewall, accessible through the engine compartment. The screws' locations are: 1 on each side by the front doors and one on either side of the shifter.

To access the side ones, pull back the trim piece that goes from the bottom of the dash across the carpet and you will see the torx 25. To access the middle ones, remove the console and you will see where each side of the dash is secured by a torx 25.

On my car the middle brackets had broken. Rather than remove the entire bracket assembly (which looks VERY involved), I used J-B Weld to reattach the broken parts. After letting it set for 24 hours, I carefully tightened the screws to @7 ft.lb. After six months I am happy to report that all is secure and rattle free.

I think that Volvo should include J-B Weld in the factory tool kit.

Good luck,

Bryan

I take it JB Weld is a type of epoxy? Sounds reasonable, though I'm still under warranty - I don't trust them to do it right or completely.

Thanks for the tips. BTW: how do you like the ride with the Bilsteins? On 740's they were harsh and factory is harsh enough on our GLT's.

Mike,

Yep, it's an epoxy. It seems to work well w/Volvo plastics.

I really think the Bilsteins make the car ride & handle much better than the stock Boges. The ride is far less harsh and I have virtually no suspension crash-through.

In combo with the strut-tower brace, I can hustle it fast enough through corners and twisties to keep a smile on my face.

Bryan

Sweet, give it a go come warrant expiration.

Thanks.

Hey iv got the same thing with my 200 GLT SE! Man it gets annoying.

Mike,

I wonders if it applies to 1998 models too, as I am experiencing the same problem with my '98 S70 GLE !

The noise & rattling is coming from the instrument panel ( especially the small black panel in front of the gauges ), and the steering column.

However, the rattles & noises only happens when I go over speed bumps or traveling on rough road surfaces.

Thanks,
