Alignment question / Problem?

[smoke]

OK I got my kids cars finished, both are 3 wheelers with right front wheels lifted,

My son's car, the one we need to be fast is tracking to the left about 1 inch in 20 inches with the front left contact wheel moving to the outside of axle, ( table is level and shimmed so they should roll straight.) I have tried switching wheels and axles, around on the car, shimming the front wheel with wax paper shims on all sides of the Axel, but i cant seem to get it to roll straight.

Am I correct in understanding that the lifted wheel our (right) should not be the one making contact with the center rail, as the car drifts left, and should instead be tracking to the right moving the lifted right wheel away from the center rail ?

How can I fix this,

Do I index the nail and bend the left nail so it tracks right? or
add more shims to the left, ? and where should I put them? ie. top, bottom, right , left of the Axel?

Or should I leave it alone and see how it races at our practice tonight?

Sorry to be so long winded ;D

Thanks

I forgot to mention that the car seems fast, testing it on the table, it is a 1/2 car faster at 30 in then our car from last year that was 2nd in district by 1/16".

Hey Smoke,

I'm no expert, but I would say forget the shims. Bend the left front axle to steer the car to the right about the same as it's steering to the left now.

Take a run as the car stands now and recheck after you bend.

PS let us know how you make out. Good Luck

time consuming process to get it to roll strait on your alignment board. make sure it's level also ! I check my test board alot.

I have not tried shims, I bend the axle.


I start off with two in the rear and roll and adjust until strait ! time consuming. then add 1 wheel and do the same process.

I do use a higher test board for the two rear wheels 2 1/2 - 3 inches. then back down to 1 1/2 to 2.


I can spend easily 2 hours working on wheels for one car.
