[W126 Coupe] Re: Vibration between 45 and 60

[Richard Hesek]

Hello,

I recently had some work done on my car. The work was a regular tune up,
transmission tune up and replacing the center link of the steering. I also
had put 4 new Pirellis on the same day.

Right after this was done, I took a 4 hour drive to Ithaca. The car has
been acting strange. I could feel some vibration precisely between 45 and
60 miles / hour. And it doesn't matter whether I am accelerating or
decelerating. Do you guys have a sense for what it might be?

Thanks in advance.

 If this is new behavior you can certainly suspect it is one of the things
that was changed. More than likely tires but Pirellis are usually pretty
good quality. I am guessing that they forgot to balance one tire or they
did a bad job balancing all.
  Is the vibration more pronounced in the steering wheel or the seat?
If it is in the steering wheel you can narrow the search to the front and
also suspect an improper installation of the center link.
  If it is in the seat, it has to be something in the rear tire
replacement. Tires, balance, lug bolt torque, improper wheel seating on the
hub, etc.
