Lazer tracking - if done properly is superb.... Transformed my van after a "reputable garage" in Leeds replaced the nearside ball joints and assured me all was well . Total ***** . The tyre scrubbed off within 100 miles . Took it to the good local garage who'd just got a new lazer aligner . Took em about an hour but transformed the van . Highly recommend .
I got the local ATS Euromaster to do it right - I left the Bentley manual open on the correct page on the driver's seat. They did the tracking and got the steering wheel straight at the same time - easier because my bus has two adjustable links in the steering. And it was much better - when I took the bus to ATS, I had scrubbed a set of front tyres down to the steel on one edge of both tyres in 10k miles even though the rest of the tread was legal , as the scrubbed strip was so narrow.
