2004 XJ8 - Groaning on Acceleration During RH Turn
#1

Odd problem has cropped up with my 2004 XJ8 155k miles. Upon accelerating during a right hand turn either from a dead stop or with a curve in the road, I hear a loud groaning sound from the engine. It's a throaty groaning sound that matches engine RPM. The sound seems like an exhaust leak but I checked the system and I don't see anything obviously wrong. The noise only occurs during a right hand turn. Same maneuver in a left hand turn yields no unusual sound. Any ideas?

Try lifting the front wheel (one at a time is fine) high enough so the tire clears the ground about three inches. Grab the tire at 12 and 6 o'clock and try to move it back and forth. There should be no play. I'd start with the right side.
