my 00 S40 has 112000 miles and I just replaced the engine but I am getting a vibration. When I first started to get it I had the engine mounts and axle replaced, but I am still getting the vibration at about 50-70MPH. any ideas Please.

 

Tires out of balance?

 

Check the rims. I have a very smooth engine, with about 105000 miles, but starting at about 75 mph I get a vibration too. When we replaced some tires I noticed that one of the rims was slightly bent from the previous owner. That may be the culprit. Good luck, and let us know!

 

I had taken it into Monro and had them look at the tires but they where fine and balanced. The rims are fine to, Ive had the car for 5 years.

 

yea i have the same problem and its not the rims...and still looking for the answer.

 

Others having this problem have traced it to a front drive axle, specifically either the driver or passenger side inner CV joint bad. I've never had the problem with my '01 so can't verify for certain. The fix is a new or reman half shaft. (Called drive axle, half shalf, CV shaft. Many names, all the same thing) Connects the trans to the front drive wheels, 1 on each side.
