Front tyres issue
« on: 26 February 2015, 14:58:53 »

I happened to check my tyres yesterday & found they have been totally slaughtered on the very inside edge :o, So went to get my tracking checked before getting the tyres replaced, They said my tracking was pretty much spot on so must be my camber angle is out, My question is what has caused my camber angle to become so far out?, Also has anyone used one of these?, http://www.ebay.co.uk/itm/301272192717?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
I have checked all ball joints & have found only slight play in a track rod end which i have ordered,
Also is there a "how to" to adjust the camber?.,,,Cheers. :y

I use a spirit level, basic trig and some bolts screwed into said spirit level.

Very accurate and when checked on a Hunter setup was only a few minutes out (which is well below the tolerance of the machine).

Of course you then need to setup the tracking.

Camber goes out as the suspension ages and sags a bit.

Cheers Mark but not sure how you use your system & "Trig" to me was a character in Only fools & horses ;D, I have ordered one of those things I mentioned & just hoping that comes with instructions such as does the car have to be on the ground when adjusting, The Haynes manual isn't much of a help but then that is no surprise.

Alf, I've looked at those gauges before, and they don't have the resolution you need.

Google 'Wixey digital angle gauge' for what I used. It's magnetic, so you cabletie a length of angle-iron across the wheel, and stick the gauge to that. You zero it first on a straight edge placed between the front wheels. No trig is needed(not that it's difficult) as the gauge reads directly.
This is done with the wheels on the ground, which makes adjusting the camber a bit tricky. But possible

When I finally got my car setup properly, the machine readings were the same as mine.

Like this:



You must always setup the camber on flat ground and with the wheels loaded.

I seem to remember the difference top to bottom being about 11mm

Cheers Nick, The tool on the Bay has a magnet on it which admittedly is a fat lot of good when the wheels are alloy so i can see why you used a bit of angle iron, I don't know if i have any angle iron or steel bar about but I know my neighbour has got some old steel wheels with tyres off a zafira so I guess i could put them on for the purpose of measuring if it comes to it, Anyhow I wont be doing it just yet until i have changed the track rod then I can make a day of it. :y

.....Depending on wheel size.

....then master gets it checked properses. They sees it, they sees it proper. Master can't do it proper without checking, no he can't.

Tyres still wearing even after 2.5 years.

That's a bit more sophisticated than my cable ties and angle-iron, and I might have to copy it. If sophisticated is the right word for something made out of bent studding!
It is a pity the traditional Dunlop tracking gauges aren't much use on an Omega.

These bolts provide +/- 2 degrees of camber adjustment. I've had these on my Catera for about 5 years and the wear inside tread wear has been somewhat reduced. Granted, my car is lowered 25.4 mm (1 inch) and the bolts compensate for the added negative camber added. On a nonlowered car the they would allow you to dial out more neg camber than on my car. I'm out of my element here so feel free to correct me (like you need my permission).
