Mazda 3 Wheel Vibration shake

Smoothing out my Mazda 3

Royal Blue XJ List Scouting trip

A few of the XJ List members went to Royal Blue to see what we could find.  Adam took us to an amazing trail to the sand pits just west of the interstate.

Porsche 944 Torque Tube Bearings

I read through the procedure on Clarks Garage. I also watched some Youtube videos. These looked intimidating, but I decided I had to give it a go.

I began by removing the shifter from the rod and the torque tube.  I then removed the transaxle.
