Hey Brother P! In just over two years, I must say not badly at all. I bought the car second hand in 2013 and the rear SAM unit needed replacing, none of the rear lights were working. R 10 000.00 later, but it was paid for by the selling dealer. Since then, there was a thrumming vibration that started about six months after I took ownership and I was petrified that it was the diff. It led to "Google doctoring" and I was horrified at the consequence of such a catastrophe. Thankfully, after sending the car in for new tyres, it turned out that one of the rims was buckled (my fault) so I had all four straightened, cleaned up and the vibration's disappeared.Let me know how yours is treating you. Just had to do some work on my AC compressor. It was causing my engine to stall or alternatively the multiv belt to snap.
