Hi, I have a 4/4 2 seater 4 years old, when I have a passenger and let’s say drive enthusiastically, i occasionally get a noise coming from the rear axle, yesterday I checked under the car and evidence of the rear uni joint coming into contact with cast alloy tunnel casing. It has accured a number of times over a few years. Any thoughts ?

No. 1 fix contain my drive I g habits! Never happens when the misses is the passenger.
