Hi everyone, I recently replaced the timing belt tensioner and pulls on a 2002 s40 1.9t. I lined up all the markings (3 of them) and put it all back to gether. Now I am getting a strand vibration when I drive over 45/50mph. The car idled great in park and no shakes when reved in park. Gets a little more shaker when in drive. Is this the timing belt or something else? I have noticed no lost in power but actually a gain in power. This is the cars first timing belt replacement at 138k due tot he last owner thinking the car had a chain. Any help would be appreciated!

 

did you remove the harmonic balancer when you did the timing belt? Maybe it was not put back on properly or was not sufficiently tightened?

 

Maybe the 2 bottom motor mounts suffered damage when the engine was moved for the belt replacement? Or the upper mount is still loose?

 

i am thinking the balancer is no good myself. The rubber is all cracked so I think when I removed it was its last time. Ordering s new one it's all I can think of. The car runs great otherwise. And the mounts all look good
