Re: 1970 Chevelle front end question
Sometimes alignment shops don't check the front end out thoroughly because if the FE needs work then they can't do the alignment till its fixed.So you should check the front end out yourself if you can or get someone you know who's experienced at checking a car out.Your look at the tire and saying it sometimes leaning in at the top could be something worn out and a worn out steering box wouldn't cause that look.
...Start by jacking the front end up with a floor jack under the lower control arm.Position the jack around where the spring seats in the lower control arm or(LCA).OR better yet,use two jack stands and a floor jack.Jack it up at the frame and then position the jack stand under the LCA right under the spring pocket.Do this on both sides.That loads the suspension enough to check it out properly.
...After you get the tire up enough to grasp it at 6 and 12 o'clock you can check for ball joint and control arm bushing play (or looseness).Push in at the top while pulling out at the bottom and repeat rapidly. There should be no excessive movement.
...If you do feel movement you'll need to see exactly where its coming from.If you're not used to doing this yourself it helps to have someone to look while you work the suspension movements.
Now to check the steering linkage (idler arm,center link,tie rods & sleeves) grasp the tire at 3 and 9 O'clock and repeat the push/pull motion.There should be steering movement but the linkage shouldn't have any excessive play at each joint.
Check it out first before you start any replacements so you know what needs fixin and what is still good.
