Volvo: 1995 Volvo timing belt, car ages, steering wheel

Question
I recently had the timing belt changed on my 850 gls wagon now when I drive down the road it vibrates, I really feel it when stopped at a red light,I can feel it in the seats in the steering wheel, everywhere.  Doesn't do it in park, and only slightly in neutral. It did not do this before.

Answer
Mary,
Not real likely that it is related to the T/Belt. Does the engine itself run rough? Most times I find the Motor Mounts are weak and that will cause the rough feeling in the entire car. Lift up the car and look at the small rubber snubber just below the trans if it is touching or very, very close to touching try the mounts. They wear out as the car ages and that causes the mounts to sag and not properly support the engine weight, therefore causing the vibrations.
