Tracking issues
I’ve had a complete suspension rebuild on my ZZT and tracked it using a tape as my local tame mechanic doesn’t have a tracking setup.
I took the car to a local auto centre that does, they dialed in the fronts and tried with the rears but said they couldn’t get enough adjustment on the passenger rear wheel any ideas why this is the case or how to adjust it into line (it’s +4 degrees and they say it should be 1.3 degrees)

-1.3 degrees is I think at the maximum end of the adjustment. +4 degrees actually sounds like something is out of shape, but maybe the tourers are different? See table here https://the75andztclub.co.uk/forum/s...30&postcount=3

T-Cut has posted a chart on here somewhere showing the tracking for all the wheels.
I expect he will be along shortly to give you a guide. ( Unless of course you already have it.--Lol. ) |

Here's the (final) revision for wheel tracking as defined on Technical Bulletin TB0061(3) 2004.
Not clear what the '1.3 degrees' refers to, but it isn't within the toe or thust angle specs. Remember only the toe (and thereby the thrust angle) is adjustable. All other parameters will be either in or out depending on the state of the suspension. The correct adjuster tool for the trailing arm mounting is MGR No.64-021 or equivalent. TC TC |

Richard, the rears need to be adjusted before the front, or the car will end up crabbing
Full tank of fuel too, and unless you are not as rough as me, don't use a piece of string to set the rears.............however after 24000 miles since fitting the new upper arms, the rear tyres are wearing evenly Of course no one has yet mentioned the possibility the the trailing arm front bushes may be clapped..........

Hi Brian
Swing arm bushes are only 4 weeks old came from Rimmers It turns out the guy doing it was a muppet just hired from Kwik fit! He didn’t do the rear first but was working round the car. Instead of using the adjusters on the front tie rods he decided to remove the tack gaiter and partially disassemble the inner tie rod to a just it! It rattled like a bag of spanner’s so I took it back to my tame mechanic who discovered the inner tie rod was attached to the rack by one thread on the nut! Needless to say frank views on workmanship were exchanged over the phone won’t be going back there again even though the offered free tracking as compensation! Are the figures in the table the same for a ZTT? Cheers Richard
