LLAMS and wheel alignment.

[Fred Nerk]

I hope this is not a silly question.

I read here that when getting a wheel alignment it is necessary to find a place with people who can put the suspension into a special mode before performing the wheel alignment or the special mode needs to be set by a LR dealer before getting the alignment done and then we go back to have the normal mode restored. Is the ability to select the special suspension mode widely available?

I am also considering getting a LLAMS kit and so I am wondering if there is a LLAMS setting which can be set for a wheel alignment or is this something that could be included in future versions of the module? This may make it much more convenient to get new tyres fitted etc.

The wheel alignment tight tolerance mode causes the suspension ecu to more get each corner's height closer to the target height than normally where 'near enough is good enough' for normal use. The Llams height controller has no ability to influence this as it only modifies the sensor signals without communicating with the ecu.

Faultmate MSV-2 units can put the vehicle into 'tight tolerance mode' Do a search on Faultmate. Look up ' Blackbox Solutions ' on the net, or talk to HardRanger locally. HardRanger used to set up complete units for clients.

Thanks for the information. The Llams looks like a good option for all the reasons put by other contributors.

I can not justfy the cost of a Faultmate despite it appearing to be a very interesting tool. It is a pity LR have not made the tight tolerance mode to be easily engaged.

Mine had an alignment done without setting TT mode after the factory settings caused tyres to scrub out. The engine was turned-off after the driver was out to allow a correction for the driver's weight to be done then the engine bay main suspension fuse was removed to prevent the ecu from making any adjustments during the procedure.

That seems ironic that you (Graeme) of all people should get a car with a suspension/alignment issue. ;-)

Removing the fuse sounds like a simple "work-around". Is this something that wheel alignment places know about and understand? I would be able to explain it to them I imagine it would work with other cars with computer controlled suspension systems too.

I doubt you can make that assumption. The fuse out is a shortcut to try and achieve the same result as tight tolerance mode. It may stop the suspension from moving with the fuse removed, which is essentially what you are trying to do in TTM. IMO, that makes it a big stretch to then assume that an alignment done within TTM was somehow damaging tyres, and another done in in a simulated TTM ( fuse out ) can deliver a different result. More likely the first alignment was incorrect, or did not suit the conditions the vehicle was driven under.

The original, factory alignment was within LR specs but left and right front and rear cambers and front castor were at opposite ends of the allowable tolerances, with the left side on the wrong end. It had nothing to do with TTM, only that my local alignment even without TTM having been set produced a far better result. The factory alignment was just plain sloppy.

I now have a Faultmate so will set TTM for any future alignments.
