Wheel alignment

I run hugh Camber up front, but I have different A-arms

A complete alignment will be all four wheels. You need to find a shop that understands the procedure for aligning the 928. If they can not, or will not, align the car without lifting it from the ground, drive away.

928's are really a difficult car to align and if they don't recognize that then they either are not doing it right or are clueless!

If you are running some negative camber up front (and we all do...some more than others) then it sounds as if your fronts are wearing properly as well. As long as the wear on the left side matches the wear on the right side and you are not unhappy with that inner tire wear up front AND the car handles well, then I say LEAVE IT ALONE! Don't fix what ain't broke as they say!

So you're saying that running negative camber (which I have) and wearing the inside track of the tire smooth before the rest of the tire tread is worn is the way it's supposed to be?

I do get a little shake and the front feels somewhat unstable at high speeds (80 mph +) which from my understand could be the result of the alignment being off. The problem I have is not having anything to compare this too. I haven't driven another 928 at 80 MPH + to see if what I feel is correct or not.

If you are running the inside edge of the tire much more than the rest of the tire how in the world could you POSSIBLY wear the rest of the tire at the same rate??? Just think about that for a minute. I'll wait for you...



Rick, just look at a race car running a ton of camber, the outside edge (other than from cornering) will be untouched while the inside edge will be GONE. Just a fact of life. Run ZERO camber if you want to try and wear them evenly and then don't corner to fast or you will then wear the OUTSIDE edge more. On the wheels that steer the car it is impossible to get good handling and even tire wear across the width of the tread. For a brief period there were tires with built in camber... Pretty cool! I bet those wore evenly...

Your car should be rock solid and smooth at 150+ let alone 80. But it is not always (perhaps not even usually) an alignment issue when you get the shakes. It is probably and out of balance wheel...could be that it was put out of balance by a poor alignment though. The thing that you are really looking for is left and right side wearing the same way at the same rate. You also want the inner edge that is wearing to be wearing smoothing and not have any scallops or dips in it. I bet if you were to just change out the tires for new tires (properly road force balanced) that your shakes would go away.

All speculation at this point since I have not driven your car or seen your tires... Report back with more info when you get a chance to try new tires or get an alignment (I'd start with the tires though!)

Any of the new Hunter alignment systems installed in garages have no need to lift the tires to attach the alignment heads. The systems have a video display of how to align the car and all the settings are stored in the computer.

Most of the Sears shops have them, many independent shops have them. I just make sure the shop has the new equipment and instructions are on the computer screen. After that, no matter how young the technician is (having never seen a 928), they can do a good alignment.

Just make sure they have equipment that doesn't require raising the wheels to install the alignment head.
