First what would u estimate on a new rearwindow on my 85Iroc and why does my car move to the left very strong when driving....thanks for all the help.

 

dont know bout the window subject but the pullin to the keft part sounds like you tie rod or pos you ball joint.. more likely it's you tie rod.

 

Is the tie rod going to be a easy fix if that is the problem. Thanks for the response

 

sorta.. lol. it's pretty easy to change you tie rod.. but your going to need an alinment done. witch im guess'n your doing this all in your drive way witch you can't do a proper alinment with out an alinment rack.. take it to a shop..bought 100$ will cover it

 

$100 seems kinda high for an alignment, they ussualy only bill at half an hour around here. You should be able to get one cheaper than that if you shop around a bit.

 

is it pulling when your hitting the brakes? or just plain driving?

 

It pulls when i'm driving

 

yea sounds like your tie rod then... but might wanna look into your caliper a little as well, it could be a little bit "locked" against the rotor causing a bit of a pull. but like everybody else said, most likely the tie rod.
