lately the z hasnt been handling so well. whenever i go over a larger bump or pothole, the rear feels like its gonna break out. it feels loose. ive narrowed it down to a few things:

uneven tire wear
bad end link (maybe)
terrible camber


if anybody can help me diagnose the problme,please let me knw

 

well it could be alot of things check your rear tires see if the waring evenly if they are that pretty much narrows out bad end links or terrible camber. What kind of springs do you have if they are too stiff it could get shakey if there too soft and hitting the bump stops? Is it wet are you on old or new tires? there are a lot of things that you would have to look into. It would better serve you to list all suspension mods and tires wheel combo you have.

 

possibly blown suspension? Maybe just one strut

 

check your alignment... your toe might be messed up.. it happened to my car once i changed to my winter setup... the car feels darty and loose in the back... After an alignment, the problem was fixed.

If you look at your rear wheel (birds eye view) and it looks like its pointing in wards //-----\\ then you need an alignment.

Hope this helps.

 

yea i definately have alot of negative camber.

i have yet to get to new toe bolts. my tires are almost bald in the rear, maybe because its a staggered setup, so i cant rotate it, thats why its wear is so uneven.

my suspension is fine, but im getting coilovers over the winter.

any other suggestion would be appreciated.

 

Check your tire wear ( the inside, not the outside). I ran a pretty aggressive negatitive camber at the rear at one point (3.9) and my rear end doesnt stay planted after driving 4-5k KM. I thought something was wrong but then noticed my inner tire was really worn out, hence i didnt get enought traction. I changed my tires and the problem were gone. 4-5k KM later same thing happened.. i decided to adjust my camber.

 

i im getting toe bolts and rear camber arms to straighten em out. im at -3 degrees

 

Its called bumpsteer, and somewhat difficult to adjust

 

Blown struts could also easiely do that, there are plenty of things that will make it do that. You just have to narrow it all down.

 

it's ur toe; too many folks out here live with neg camber, but never do anything to treat the toe misalignment

 

Bad toe = bumpsteer, every little bump ur car wiggles in the rear! Google it up, there are a few ways to fix this.
