Load conditions for tracking

[ed_crouch]

Ive noticed one of my front wheels is a touch feathered.

Better call home and beg the use of the tracking gauges, methinks.

Question is, at what load conditions should the adjustments be made??

2 sacks of spuds per seat or empty??

Any knowledgeable people out there?

Well Idealy the same as the car is going to be used.
Also the car sound be moved back and forward after each adjustment to settle the car, unless you have friction less pads.

as any adjustments will cause fiction loads so will not be correct untill these loads are removed. normally you would have to slightly under-adjust. due to load friction. 95% of tracking places will not do this though.

The figures are normally given for the car with no one in it i.e. unladen. Remember that the only setting that can be changed normally is the toe and this is dynamic as it will vary as the suspension moves.

Feathering is usually more usually associated with excess camber but this can be caused by spirited driving and nothing to do with the car's set up. As the car is pushed harder, it rolls more, the camber changes and one tyre edge gets worn more. The camber can be adjusted to compensate but then when the car is not driven so hard, the camber adjustment means that it is now wrong and the end result again is unsymetrical wear.

Thanks, fellas.

mmmm, wonder whats causing the feather on one side... I dont drive it THAT hard?!?

Perhaps some laser alignment is called for then.

do you only make left hand turn's

Also you could have a week spring or duff shock, and there is too much travel and thus changing the tracking too much.

On a wedge you can turn in at a rate that is able to cause this even at low speeds. Been drifting in the wedge (at least an attempt to learn it) and it could happen with a too sharp turn-in and speeds as low as 20-30 miles/hour....

But having the alignment checked would be first on my list, and take it from there.
And if you are eager with turn-in, wedges can powerslide to help you (but you'll wear the rear tyres evenly ;-).
