My wife turned over her 99 Volvo S 70 to me when she got a new Japanese car. When the car is in gear but stopped at a light, there is what seems to me more than normal vibration through the brake pedal - sometimes worse than other times. If I shift to neutral the vibration stops. The dealer denied there was anything wrong with the car, and said that this was normal. (I have a '90 240DL manual transmission, so I was not used to this vibration, so what do I know?). But it doesn't seem right. Is this a transmission issue? Do other S70 AWD owners experience this?
Just in case you are still having an issue.
There is a suspension mount on the right side of the engine bay just under the timing cover. Remove the right front wheel and the two 10mm plastic nuts in the fender liner. Now pull back the fender liner. Using a flash light you should be staring at the crankshaft harmonic balancer (big round circular pulley that has a large bolt, 21mm, in the middle and four smaller, 10mm, bolts around it).
Just under the pulley there is an engine mount turned sideways. Use your flashlight and a mirror if you can't get a good look at it, Most likely you will see that the rubber is pushed apart and in pieces. The upper portion of the mount that bolts to the engine with 13mm bolts will be sitting on the sub frame. There is supposed to be rubber between the upper portion and the frame. Just look closely because from time to time it will just sink into the mount and may look ok unless you look close.
If the mount is ok then you will need to take it to a Volvo shop. There are a couple of service bulletins for vibration and harshness on early (1998-2000 awd cars). They relate to some adjustments or shim instillation on the left side mount, but I can't remember the settings off the top of my head.
I hope this helps.
One of the eng mount needs to be replaced good luck

Vibration is common onvehicles this happens with moving parts, however vibration is all relative. how severe is it? and are there other problems like does it have a hard time shifting. does it bog down when hyou accelerate? post back and i can pinpoint a solution if there is a problem.
if it seems louder than normal and you feel vibration it could be that there is an exaust leak under the vehicle. believe it or not an exaust leak can vibrate the vehicle. I would check this out. If the vehicle is running good then I seroiusly doubt it's a transmission problem. please rate this thanks

Otherwise the car runs OK (relatively speaking for a newer Volvo). I do think it is louder then it ought to be when I accelerate hard - also making me think that there is a tranmission issue. The wife's new car is a hybrid, so it shuts down after braking, so I don't have anything to compare it to. I always had manual transmissions.
Had dealer check for exhaust leak, reported to be none.
Replaced universal joint - reduced the vibration a bit, but still noticable.
