I ve been using the Track Ace tracking guage for a few years now. Its self calibrating and easy to use. At under £60, adjustment being so easy on our buses and the price of having it done profesionaly; you know it makes ladies. Check out Demon Tweeks and drool over all the shiny prescuos things.
Looks ok for a check, but if you altered the tracking it looks like you have to start at the beginning again. That said, even second hand, old style tracking guages can be expensive. I was lucky indeed and bought a set for £80. No batteries either. I'll stick with what I have I think.
You jammy b+@*er Zed You re right, you have start afresh when you ve made an adjustment,but it only takes a minute. Can be a bit of a bind if you don't hit it in the 1st few goes but its quicker than going to the garage. Green eyed monster looking at your tracking rig! Top bargain bud!
I'd been looking for years... A simpler way to do the camber would be handy. I use a digital inclinometer like one of these, but it's a bit of a fart about, it's really meant for setting bench saw blade angles.
Get a nice straight "thing" that spans from wheel to wheel. Put where you will roll the wheels to in a mo. Zero the guage on the "thing". Move van to "thing" position If you have wide 5 you can get it on the drum. Otherwise rig up something to sit on the rim and span the grease hub thing/castle nuts. Then set the tracking. That's what I do and my van goes in a straight line when I let go. If you (or I) do this and it's still wandering/pulling, new tyres are the cure.
I ve got a dial clinometer at work for setting the cut angle on the lawnmowers. Never gave it a thought for camber. Time to do the torsion ball joints. Cheers Zed you ve just made the "to do" list longer!
