Thread: TTM - refused to do it this way?

This doesn't make sense. Why not let you put it into TTM? What does it matter to him? Even if he doesn't agree with it, no skin of his nose!

Thinking about the shops responses further and their non negotiable approach to not allowing the TTM, I’m now of the opinion they may be confusing TTM with access mode.

like you pointed out, if they understood it why would they care one way or another if I wanted to put it into TTM, it would make no difference to them.

If I’m right the shame of it is they were just 100% unwilling to even discuss it and hear me out, it was within 20 seconds when he said “if you’d like I’ll bring it back out the front and you can take it somewhere else”

it will be no benefit to me but moreso for any future customers there, if anyone has the section in the workshop manual which says to do TTM I’ll happily email it to them in a friendly way just as a kind of FYI.

A few years ago I had a W/A done on my 2009 RRS and enquired if they knew about TTM. Reply was that they did but knew how two "allow" for it without actually putting it in TTM. The fella is a very experienced guy and races cars, so understands all about steering geometry etc and I must say after 30,000 odd klms there was no visible wear front or rear.
Back in the 70's and 80's I specialised in servicing Jaguars (and others incl R/Rover) and we were supposed to use a (Jaguar Service Tool) special plate to be jammed under the upper control arms so as to simulate the extra weight of 2 people in car. This supposedly allowed correct camber to be set.
Of course we never bothered about fitting it 'cos we proved over the years that it made not the slightest difference, by watching the camber dials on the W/A machine to see if they'd respond to a camber change after removing the plate.

Sounds as useful as Radial Tuned Suspension

Now now..when I was a lad and a chainman we had Holden S/Ws..all pre RTS. Then we got a HZ wagon with RTS.

Sooo being Council cars we had a race between the old and the new with RTS..up the Ferntree Rd to Mt Wellington..and the RTS wagon killed the old one through the bends. It was noticibly stiffer in the suspension with far less body roll. Still a gutless heap of junk..but better than the old cars that's for sure. Then we got Commodore wagons...not much better but less Titanic like🙄

How did Holden get away with selling such junk back then?😞

Here you go.

I printed this off for my wheel alignment guy and he was genuinely appreciative.

Description of what TTM does from the Gap Diagnostics tool manual.



What I suspect many alignment places may not realise is setting TTM will actually activate the self leveling function more often if the vehicle is moved as it will aim to maintain +/-3mm tolerance instead of the normal +/-10mm tolerance. Hearing the suspension make small adjustments more often could be off putting for some even though it is working as intended for a wheel alignment.

That’s brilliant, thanks guys.

anyone finds themselves in need of a wheel
alignment while in the NT there should be a Bridgestone store with all the information soon
