When it comes to bearings the Timken bearings are better than Moog.
Although Moog does make good quality bearings as well but Timken has higher quality and longer lasting bearings as Timken mainly focuses on manufacturing of bearings as well as wheel hub units.
Moog makes good quality bearings as well and they also make other automotive parts including suspension parts, steering parts and hub assemblies but Timken bearings is what I prefer to use although I have had good luck with Moog wheel bearing hubs as well.
I try to mainly use Timken for bearings but if I can't get Timken I will use Moog.
Moog auto parts makes a variety of different auto parts which include sway bar links, bushings, control arms, tie rod ends, ball joints and high quality steering and suspension parts.
Moog also makes driveline parts and wheel end parts and they are known for their emphasis on quality and innovation and offer parts which aim to match or even exceed OE original equipment performance.
Quick Steer parts are made by Federal Mogul Corporation which Moog is also owned by.
Federal Moguel Corporation makes quick steer parts and most specifically the "value" line of suspension and steering parts.
Moog is Federal Moguel Corporations premium brand and is also owned by Federal Mogul Corporation.
And Quick Steer is the more economical cheaper parts option.
Moog is owned by Federal Moguel.
Moog was bought out by Federal Moguel Corporation.
And so Quick Steer is owned by Federal Moguel and is Federal Moguel's value brand and Moog is their premium brand.
In a way quick steer would be the same as Moog although Moog parts are higher quality made and quick steer although still good parts are lower quality parts than Moog parts are.
Moog Parts are also made all over the world including in China.
Some Moog parts are made in the USA depending on the part.
Quick Steer Parts are made in multiple different countries which include China, Turkey, Mexico and even Taiwan.
Most specific Quick Steer Parts such as tie rod ends, are often made in Taiwan although some Tie Rod ends may be made in Mexico.
