I got tired of god-awfull noise that my car's rear LCA bushings were making, so I replaced the lower control arms.

There are two of them on each side. The sorter (A) and longer (B) one. I got the OEM LCA B, and Dorman LCA A. The Dorman LCA seems to fit just fine (didn't do the alignment yet), but unlike the OEM part, the Doorman bushings didn't have the dowell pin at the end that connects to the knuckle.

Should I be concerned about this in any way?

 

I'd be. Can that dowel pin be removed and transfer over?

 

Nah. The Dorman bushing has a plain bore that doesn't accept any dowel pins... So much for the Direct OEM Replacement...
