940 Questions 900 1991

Hi all,

This is my first post to the list. I've enjoyed reading the digests and now I hope I can make use of your collective insights.

I have a few annoying problems with my 940 and questions about each are posted below.

1. When my mechanic replace the radius rod bushes about 6 months ago ever since there has been an annoying squeak which is definitely coming from the right hand (drivers) side of the car. It is most noticeable under brakes. If I bounce the car on that side I can hear rubber to metal creaking coming from the upper strut bush or bearing and in the vicinity of the radius rod to control arm bush. I've tried some silicone spray a couple of time and it made no difference. The squeak I hear while driving does sound like something is loose but I can't pinpoint.

2. Do Volvo's with ABS naturally have a slightly soft feel in the pedal? I recently replace the front calipers and hoses on my 940 and had the brakes pressure bled but the soft feeling is still there. the brakes themselves seem to operate fine though.

3. Occasionally all the right hand side speakers on the stereo will fade out when playing a tape. If I eject the tape then put it in again the problem corrects itself. I've tried cleaning the heads but to no avail.

This problem only occurs with a tape and not the radio. The car has the factory Graphic Equalizer by the way.

4. I noticed a couple days ago that someone wrote about cleaning the idle air valve to fix a rough idle problem. Could someone provide some instructions on this? Please?

Thanks all. Sorry about the long post

    -Sounds suspiciously like the pinch roller is "barrelled". -Basically, the tape is 'weaving' off to one side of the head, and you're losing tape to head contact with one channel.

    since the car is about 10 years old, I'd say it's normal for the rubber parts to need replacing anyway... -if you can get them, that is! -If you do decide to try to get a replacement (good luck!) then you might think about replacing any belts while you're at it. -The slipping clutch on the take-up hub may also be a little too slack... that could be more of a problem...

    Brad,

    I have a 94 940 Turbo sedan and I will say that the pedal is extremely soft. I just did a rear brake job on my 1984 Firebird and event though the brakes on it don't feel like they are going to lock up, the pedal is very firm and feels like I get braking action immediately.

    I don't know if it is because of Volvo's ABS or 4 wheel disc brakes. I know that even though the Firebird has drum brakes in the back, the front discs are designed to ride away from the disc but have a quick takeup feature to get the pads moving when you want to brake.

    Did you use the stock hoses when you had the brake work done? I was considering putting on the IPD brake hoses but I may reconsider if it appears that it won't really help. I don't remember if the IPD hoses have a braided steel outer sleeve, but they claim to address the soft pedal complaint.

    I'll give a couple of these a shot.

    1. Listen to everything on the suspect side of the car. It could be the new radius rod bushing, it could be something else as well, up to and including the tie rod, either inner or outer end. I've had them squeak very loudly before, giving the impression of coming from elsewhere.

    2. My dad's 940 has a softer pedal than my 240. In fact, it is quite soft. Both have ABS. But three other non-ABS 240s in the family have somewhat harder pedals without ABS. Clean, flushed brake fluid in several for equal comparisons.

    3. While the Volvo cassette player sounds pretty good for a stock unit, especially with the factory EQ, it is still worthless. I've had to throw them all out because although I've never had one die altogether, they all have had intolerable quirks such as that. Often either the wiring for the speakers or the EQ is shot, or the stereo internals are bad. Either way, it has been far cheaper for me to just replace the entire stereo with something good rather than to have it checked into. That is just my story, though... someone else might have other input.

    4. Rough idle is more likely from a dirty throttle body or a vac. leak somewhere. Had that both ways before. The IAC problems I've had have been related to idling too high rather than too low/rough. Don't adjust the idle speed or throttle switch unless necessary, after cleaning the throttle body and all of it's ports. It is all in the FAQ :)
