OK, So I bought one of these to replace the factory ball joint on my Golf MK5 that had been on the car for 18 years. Had no choice in the end because the original unit had corroded and ceased. Anyway, I have to say I was really impressed with the build quality of the Delphi ball joint. Easy to fit and handle. Very happy overall. So much so that im going to do the other ball joint on the opposite side to match just for the fun of it. Well worth the money. Thanks.
