Thread: Wheel Alignment for D3/D4/RRS is not that simple!

They did, yes...

I was surprised that even in the Brissy CBD, they don't do their own alignments....


I thought the idea to compensate if you went to LR for an alignment, was that they would put it in TTM (if the company they use hasn't the kit) before taking it somewhere else for the alignment using the data supplied by LR.

OK, sorry, must have mis-read.


I thought that they not only didn't understand the LR data and didn't do a proper TTM.

TTM reduces the acceptable variation from the target height from around +/- 10mm to around +/-3mm but does not change the target height. Setting TTM cannot possibly be detrimental because if not set then the vehicle could be acceptably low on 1 side and acceptably high on the other with up to 20mm variation between sides.

Agreed. You can complete an alignment without TTM, but it may not be as accurate. A lot of owners are quite happy with their non TTM alignments. It is up to the individual as to what you are prepared to accept.

Probably be the tyres (READ - uneven wear) that will advertise the accuracy of the Non-TTM Alignment and will dictate how happy the owners are with that stance ....

How could you possible know what the right height or level is on the suspension when it gets artificially locked mid-stream on a surface of an unknown level .... (which I believe by my reading won't actually occur by just opening doors, etc .... in other words it doesn't completely stop the movement)?

Hi Guys
will be getting my new 19" Hankooks fitted in a week and now i am very confused where to get the wheel alignment done. I do have a Nanocom but when i tried it out in the shed not much happened, i could still change the height with the switch
where to all you other Brisbanites go to for your wheel alignments?

That would be as I expect. See Graeme's post above.

The switch on the console changes the "target" height (access / normal / off-road) - this is not affected by entering TTM.

When you enter TTM, you decrease the allowable tolerance at whatever "target" height you have selected. If you are not in TTM, the vehicle can be at the selected "target" height, +/- 10mm. When you are in TTM, the vehicle will be at the selected "target" height +/- 3mm.

I would assume that the correct settings for wheel alignment would be at "normal" target height, in TTM - so is at +/- 3mm from the vehicle's "normal" highway travelling height.

This is my understanding of how it works anyway - I'm sure that someone will correct me if I'm wrong.
