Funny how one thing leads to another....
I was measuring the ride height of my car today as I was thinking of getting the SydKid group buy and lowering it a tad. As I was doing this I noticed a screw sticking out of the rear tyre. I then preceeded to remove the screw hoping that it did not go in too deep. Not so! However, I was prepared and fitted the space saver (not a good look) while the tyre went flat. As I inspected the tyre I noticed that the inside of the tyre was quite worn (with an undulating pattern to the wear) while the outside was still fine. I checked the other rear tyre and same deal.
Now, 6 months after purchasing the car I had a similar problem with the front tyres. I took the car to Pedders and gave them a lot of money to fix the problem. What I got;
1. Camber adjustment bushes
2. Caster adjustment bushes
3. Wheel alignment (all four)
4. Plus two new front tyres
And to date the front has been sweet with no uneven wear on the tyres.
So, I checked the forum and it could be many things but I'm leaning towards an incorrect toe adjustment. I thought I'd take it back to Pedders to check but I noticed something else. The ride height on the right rear (if your facing the front of the car) is 380mm but the ride height on the left rear is 370mm. The ride height for the right front is 370mm but 375mm for the left front. I'm measuring centre of hub to guard height. Now I'm not sure if this means anything but seems a little strange. And yes, the garage floor is pretty flat. Wondered if this could be a suspension issue (ie: shot shockies)? Or something worse?
Anyway, I need to be mobile and will be getting 2 new tyres fitted to the back and then take it into a suspension specialist at first opportunity. Will post any conclusions once they become available but is anyone is able to shed any light on why ride height might be different?
