Re: Steering Wheel Not Centered
slik, you don't say whether you had the steering wheel alignment problem before the wishbone was replaced? It's quite common for the wheel to be a little out of whack after replacing suspension parts. If the steering wheel is out of whack, it's never a good idea to start taking the steering wheel off and rotating it to make it point straight. Always adjust the tracking.
To add to Bluecruiser's comments about Protyre, I'd wholeheartedly recommend them too. Sometimes it takes a couple of attempts too, however careful they are about having the car squarely on the equipment, when you drive away there can be a small discrepancy still. They are happy to fine-tweak it if that's the case.
