Moog
These look high quality to me & Amazon has a great return policy. I haven’t installed them yet so i can’t rate them honestly. I’m sure they’ll work fine Moog makes good parts.

Moog still does it
I was very happy with the control arms I paid the extra money for the moog and was happy with the quality. The fitment and end results were excellent

Fits Great
Installed the two arms that I ordered and they fit perfectly. Had a heads-up on buying new hardware to install them, but Ford Motor Company no longer makes the hardware kit. I very carefully (I thought) removed the first one messing up my security anti-reversing clip on the bottom bolt, so I reinstalled it with a new Grade 8 flanged nut and backed it up with a nylon inserted nut to hold it in place. On the second arm, I realized I could loosen the nut just enough to not damage the clip, but made sure I only unscrewed the bolt; this one reinstalled just fine. Having installed the two arm, my rear-end bump every time I stopped has now gone away; problem fixed!

it's fixed the clunking.
It's crazy how I was feeling a clunking through the steering wheel and all this time I was thinking it was from the front end. it ended up being the rear trailing arm(s). 2011 Executive L

Not the Moog I knew
These seem thinner and the stamping on these had edges that needed filed off to alleviate cutting your nitrile gloves. QC has suffered , but the price is ok.
