This is a 1998 S70 with 125,000 miles. I recently had new rotors and pads placed on all four wheels by a local repair shop. Unfortunately, when I apply the brakes lightly now, a very loud rumbling noise comes from the rear of the car and is accompanied by some vibration. I am going back to the shop,...

I am trying to do the 120,000 mile maintenance on a 1998 Volvo S70, and it calls for lubricating the link arm. Is this easy to do, and is this the same thing as the steering stop?

Thanks Lee. I just read some other threads on the airbox thermostat thanks to your post; I'll have to take a look at that.

I should have a good estimate of the mpg later this week. To...

I had the local dealership read the codes in response to a check engine light and was informed that the air pump was malfunctioning and should be replaced; I was quoted a cost of $700. Thankfully, I ran across...
