My experience has been that sometimes WorldPac sources OEM parts, other times aftermarket parts made by the manufacturer of the OEM part (such as you see listed on PP parts inventory), and sometimes they source xyz aftermarket parts.

As WorldPac is owned by Advance Auto Parts, who obviously sells a ton of aftermarket parts, and the fact you've gone 0 for 2 on the two previous steering gear boxes, I think I'd get to the bottom of who has manufactured this part. It sounds like it must be from xyz aftermarket manufacturer and they make a lousy steering gearbox. I'd make sure they don't put a 3rd box in from the same manufacturer. Just my 2 cents.

Who've obviously put your trust in the repair shop. They owe it to you to do a better job of communicating what parts they're using.

I'll be sure to ask them the brand tomorrow. My family has been doing business with them for 30 years, they've never violated that trust or doing anything shady. They said they'd take care of the gearbox, no problem.

In my searches I've only seen two brands listed online. Maval and C&M Hydraulic. I've got a Maval box that I sourced and my shop installed currently in my 190E (almost 2 years now) without any problems.

I'll be sure to find out and report back though.
