Same here .................... the only time a wheel alignment has been done on mine in over 120,000 km was when I had the bushes replaced. ;)

I am with Tombie and BMKal - unless there is an indication that something is wrong dont get an alignment done - on various cars over the years my problems started after an alignment was done.

My RRS has now done 123,000km and is on its third set of tyres - still has the factory alignment and my current General Grabbers with 50,000km on them are wearing evenly on all four tyres.

Thanks guys,, the blokes at the tyre place that will do the job, seem to know about it when I asked a couple of months ago, so I'll check before I actually get the new tyres on.

I had the D697's installed yesterday and the wheel alignment done with the assistance of the Nanocom Evo. I was having wear issues and hopefully the wheel alignment will keep the D697's nice and even. They look larger than the actual size would indicate.
Can anybody clarify what the TTM setting actually does, is it simply a way of locking the suspension in a level position while the wheel alignment is done?
Thanks

TTM reduces the individual corner tolerance to +/- 3mm from the standard +/- 10mm

I am starting to wonder what could be so hard ....

I've now had three alignments since getting the LCM bushes replaced a couple of months ago, all of them in TTM.
The first was dealer organised same day as bushes (so assume TTM) and subsequent two were set to TTM by me with iiD.
For the 2nd and third ones I specifically asked for additional LH front caster.
The printouts show good values, yet it still stubbornly drifts left and requires the wheel to be slightly turned right to drive in a straight line.
it's not a huge amount but is certainly there. When held at that angle it drives well but is very distracting.

They all use a locking bar to hold steering wheel at the straight ahead position and I have wondered if this is not being done carefully enough.

My other thought is does anything need to be done with the steering wheel angle sensor? eg recalibrate.
No errors or anything so perhaps grasping at straws.

Maybe I just need to keep trying to find someone who is good at it ....

Cheers,
Scott

Scott. Add a little bit of Castor on the left front

Scott, did you have the llams loop back plug installed before entering TTM? The minor fluctuations in the height signal from Llams are within the 10mm tolerance but can be larger than 3mm - not sure if this would have a major effect on the wheel alignment.

Also, the WSM states the steering angle sensor should be calibrated after a wheel alignment

That's what's puzzling. I asked for 0.5 degree extra for the first one I organised and the most recent one the reports states 0.7 degree extra.

No I just left Llams alone.
Maybe I'll try a steering wheel angle sensor calibration.
Should be straight forward with the iiD tool.

That is why I do not get wheel alignments just because I have changed tyres or played around with something - unless there is something really wrong.

Tyre fitters seem to recommend alignments like dealers recommend injector treatments.
