This vehicle had a bent pinion shaft. Another shop replaced the broken driveshaft (exploded on the freeway) and could never solve for a vibration complaint.

We received the vehicle and after analysis were able to solve the vibration after identifying the source. The Picoscope NVH tool was utilized was extremely helpful in analyzing the vehicle issue and proving that our repair was a success even though the vehicle continued to exhibit other vibration challenges.
