Rear End Issue

[Perry Y.]

The rear tires on my 1967 point inward at the top. Any advice on where to start troubleshooting?

Perry,
You don't mention any rebuild work being done so I assume this is from regular wear & tear. Check strut rod bushings, control arm bushings, and spindle bearings. How does the rear of the car sit. I'm not positive, but I think that excessive spring wear could also cause that effect.

There are lots of possible causes. However, the very first thing to check is the strut rod bushings. I think you'll find them "shot". If so, replace them and get the camber set to specs by an alignment shop.

Another thought is that the ends of the "stub axles" are worn. If you think about it, the half shafts and stub axles (that slide into the diff) form what one could call the "upper A frame" of the rear suspension.

Thus, they're both a suspension piece and a driveline piece.

When the ends of the stub axles wear, they move inward, causing increasing negative camber that often cannot be adjusted out using the strut rods.

That's why you'll often see bent strut rods. Somebody bent 'em to try to get the rear camber in spec.

Thanks for the replies. The suspension is all new but the diff is original. The end of the stub axles sounds like the place to start.

It could also be that no one ever aligned or properly tightened the eccentric bolt that adjusts the rear strut rods.

I'd inspect those first before worrying about the differential. If your strut rods are adjusted all the way in and the bolt is tight, then start looking elsewhere.

See pic below for location of the strut rod eccentric bolt.
