I was installing splash guards on my 93 del sol Si. and noticed both front tires are very worn on the inside edges.

I rebuilt the front suspension, upper, lower control arms, shocks, tie rods, inner and outer) and wheel bearings all with Honda OEM parts. Shouldn't matter but CV shafts as well.

after rebuilding, I took it to the tire shop and had them put four new tires and align the car. Tires are Hankook Optimos.

This was 2k miles ago.

This shop has done work for me for 15 years and never an issue.

Could fatigued front coils have caused this? I didn't change those.

Any thoughts.

 

This is more than likely a toe issue. Not a camber issue.

Have them check the alignment again as the car sits. Take some pictures of the tires.

 

I don't think camber is adjustable, so slightly compressed spring can but more lucky like he said wheel toe alignment. Does the car pull left or right when driving? Or does it act/feel weird when running?

most likely from changing the tie rods. Its difficult to get them to the same length as when they came off. Did you drive for long before the alignment? I have seen shops neglect to align things bc they assume they're non adjustable even when you have $500 in alignment components

 

Wearing that quick, it's likely toe. I would get it re-aligned.


Not so much. May cause cupping.

 

Get an alignment.

 

All the parts were changed with the old tires on the car. it was then driven about 5 miles to the shop. 4 new tires were installed and the alignment done.

I got it back to the shop and they are saying the lower control arm bushings are bad allowing the control arms to move in and out. Hope to get it up on the jackstands this weekend and look at them.
