Annoying and very load screetch
Annoying and very load screetch
: Hopes this is the right thread to post this in :
I changed the stock rims on my 86 Trans Am to identical rims, but crome. Now whenever I make a right hand turn, the front passenger side tire makes a very load sound, something like a truck/semi braking. I tried taking off the tire and cleaning up the joints, but it didn't fix it, any ideas?

Do you have the factory 16" rims? If so, you may have mounted one of the rear wheels on the front. The 16" rims fitted to the TA's and Z28's have different offsets on the rear wheels than the front. The fronts are Zero offset, (4" backspace) and the rears are -16mm offset, (4-1/2" backspace) which means that if you mount a 'rear' wheel on the front, it will sit closer to the centerline of the car than a 'front' rim will.
There isn't much clearance between the back of the rim and the tie rods, so if you mount a rear wheel on the front, it will rub on the suspension, causing your noise. I had this happen to me when I had the tires rotated on my car. I left instructions that the tires needed to be removed from the rims, but they just swapped wheels. The first time I made a full-lock turn I heard the exact same noise you heard.
Take the wheels off and look at the backsides, the 'rear' rims should be labeled as such. If they're not labeled, get a level and a measuring tape and measure the distance from the bead of the wheel to the inner mounting surface. What a lot of us do is get a second pair of 'front' rims to run on the back, or get all four aftermarket wheels in the Zero offset setup. This makes the rear wheels sit about 1/2" farther out, which isn't really noticible, but makes it possible to swap one wheel for any other.
Good luck.
