Hi Fellow Members, I wonder if someone can help, my 1979 vette has the drivers side rear wheel 1 inch past the guard and on the passanger side it is 1 1/2 inch inside. here in oz the tyres (tires) are not allowed to be outside the guard. can anyone tell me how to fix this problem, I do have a Haynes repair manual but can't find anything to shift the wheels that far over . question the shims on the trailing axle does move a bit but not enough. question the trailing axle on drivers side seem narrow conpaired to the pass side could I have the wrong trailer arm on on or could someone advise how to fix the problem also wipers only accasional work any clues motor works fine without wiper pushrods conected armature spins but when conected wont work some times and is stagered movement when on and hit the ignition key cheers garry

Garry.... I'm not sure what you mean by "guard". Are you talking about the wheel well opening. Could you post a couple of photos. Particularly photos of your rear strut rods and the strut rod support bracket along with trailing arms.

I'm kinda wondering what a trailing axle is, too.
Your post is difficult to understand, but it sounds like you need to start making some measurements against the frame. Make sure the differential is centered and go from there. This is assuming the frame isn't tweaked, of course.
You could just get a tire and wheel that is 3" narrower!!! LOL!!

The diff doesn't really have the ability to be shifted in any direction; forward, aft, left, or right. It is secured to the car via the crossmember in the rear and the pinion bracket.
I would be willing to bet that you have some pretty serious problems with your strut rods, side yokes, and/or trailing arm bushings. In my experience, an issue with one means an issue with the other two.
This probably isn't what you want to hear, but IMO, its pretty important to have the whole rear end set up correctly.

thanks
thanks to all,,, looking from the back of the car the wheels are off center. The drivers side wheel is about 1 inch outside the guard and on the other side it is 1 and a half inches inside the guard ,in other words the wheels are off centre to the car. question would the diff be exactly in the middle of the car or off centre a bit and the drive shafts and connecting rods be on the wrong side. The body is sitting on the chassie same each side, the trailing arm on passanger side is about 1inch yet the one on the drivers side is 2 inches wide at the shims on the chassie this I think could be the problem the conecting rods appear to the same length a bit hard for me to get under main thing is is the right and left trailing arms the same width or not ( what is the difference between the right and left trailing arms other than the reverse hand , perhaps the 2 inch one is wrong causing the wheel to be outside the guard of the car and the passanger side is inside the guard ....question the crossmember that holds the diff could be in the wrong way also if the diff is not cental to the car. thanks for the help . I am old and not good computors but can use a camera but will need my son put on the site but will do if members cant understand
my son will be able to post in a few days when he comes here

Well, there ya go, Stoge says you don't have to worry about the diff, because it's secured to the frame. Apparently, it is secured in such a way that it cannot fail, be reinstalled incorrectly, or sustain damage in an accident.

the guard is a mudguard called here in australia it has the wheel arch that covers the wheel here in oz it is to cover the tyre here. In usa tire. Different words sorry. It is illegal to have your tire out past the body line hence the wheel arch or mudguard ... My vette has the drivers side out past the wheel arch by 1 inch and the other is 1 1/2 inside

Garry,
Even if the rear end is offset by 1 inch- neither tire should stick out past the fender lip. Do you have the stock size wheels and tires? If it makes you feel better, the offset you're seeing is not rare at all. Many cars came that way from the factory, including mine.

Garry, with that much mis-alignment check the body position on the chassis. Car might have had a body off and not put back on square.
Also, might have had a hit and not realigned the body.

the body is exact on each side on the chassie at the rear the chassie is equal on b oth sides, I think the problem is that the trailing arms are not the same thickness at the shim points one trailing arm is 1 inch thick and the other is 2 inches thick,don't know if the arms are supposed to be the same thickness thanks garry
#13
does antone know if the trailing arms are the same width on each side of the car as I have the drivers side at 2 inches wide and the passanger side is one inch thick, question if they are both the same width which onr is right for a 1979 t top one inch or 2 inch can anyone please advise if their arms are the same width cheers garry

Where one the arm are you measuring the one inch?
I'd have to get out a tape to by absolutely sure but I've got a brand new set on the bench and I'd say they are mirror images of each other.
At one point I have checked and the distance from the spindle mating surface to the front bushing (offset) is the same on both too.

Well ok, Scott. It seems like you want to pick an Internet keyboard commando battle with me for some reason.
How about instead of going out of your way to make someone else sound like an idiot, enlighten us as to how the rear could be shifted in any direction.
And sure, the thing could be loose in there. Off the top of my head, I can think of at least 6 bolts that would have to be near if not completely missing for it to be anywhere other than where it is supposed to be. And while the chance of that happening being as rare as it is, if it were the case, you would still have the same issues with bushings and side yokes.
