Here we’ll be talking a lot about specific MOOG technologies, and we welcome your comments. (There’s also a separate, product-specific blog you may be interested in checking out.)

As time passes you’ll be reading posts by several of us, with a variety of perspectives: engineers, R&D guys, technicians, marketers and others.

No matter who’s doing the writing, you’re probably going to notice a lot of pride and excitement coming through. But hey, MOOG technology is used by more technicians and NASCAR crew chiefs, so why shouldn’t we be excited to talk about it?

Stay Tuned!

Thanks Paul for your post. You have purchased a MOOG Asia-Spec component. Rest assured that the part you have installed has been designed and rigorously tested to meet or exceed the OEM specifications for performance. This criteria includes stud swing, deflection, socket torque and steering response. Thanks for your purchase!

Hi Tony

Thanks for your post – unfortunately, we no longer have springs for your AMX – although we still have the components for the steering (see http://www.fme-cat.com).
I have the MOOG engineers looking into how we can help you further – can you tell me the engine you have in your AMX?

I recently purchased 2 new lower ball joints for my 2005 Toyota Sequoia. (K80521, K80522) I thought these would come with zerk fittings to grease the ball joints, they did not. When you move the ball joint, it feel very rough like it has no grease in it. Are these pre-greased? Is the small bolt on the side to install a grease fitting, and why didn’t one come in it already? Thanks for you help.

These parts should have come with grease fittings. One of our engineers will be contacting you via email to resolve this.

In reference to the tight fit, yes, that would be normal if you are trying to move that by hand, and yes the parts are pre-lubed. The provision for greasing them is to periodically infuse with fresh grease and to flush away any contaminates that may have entered the part.

Thanks!

I’ve recently purchased, a month or two back, part number K620175 as well as K620174 for my 2008 Dodge Ram 1500, and the one for the driver side is having issues holding grease. I will fill it, and the boot will swell but after driving maybe one day, it will empty out most, if not all of the grease. Just to be sure I have the part number correct, theses are the control arm and ball joint assembly. I was curious if maybe this is a defect or if there’s something I have to do in order to keep the grease from coming out?

First, be sure that there is not a rip or tear in the boot. If the grease is escaping at the small part of the boot where the stud attaches to the knuckle, where the grease relief valve is, then this is normal. The component does not need to be fully packed with grease to be protected.

Hello,
I just replaced both upper (K7394) and lower (K7397) ball joints on my 2002 Dodge 3500 rwd solid axle. I noticed when I hung the left side axle back on the new upper (K7394) ball joint the stud dropped about 1/2″… I thought this was wrong so I went back to O’Reilly Auto Parts to verify that other (K7394) do the same thing, which they do!???

My question: Is this normal for the stud to move axially apprx. 1/2″ on the (K7394)? All 6 of the other (K7394) I have looked at from 2 different O’Reilly Auto Parts do this. CONFUSION REIGNS….

I hope the (K7394) are designed this way, but until I here other wise from Moog I will not finished the reassembly due to concerns about the stud’s movement in the (K7394) ball joint.

Thanks in advance
Keats

Yes, that is the design of the stud. These parts are just like the design mentioned in Problem Solver 29007.

There also should have been a mention of the axial play (up and down) in either the enclosed instruction sheet and/or warning tag.

Thanks for installing MOOG!

Is it normal for a new moog ball joint with fresh grease to feel rough and feel as though its scratching the side of the walls of the joint? It isn’t smooth even with added grease. It feels like its slowly shaving the joint when turning it by hand.

What is the part number or application you are referring to?

BTW what grease do you recommend for this ball joint? I’m pretty sure I used “Molybdenum disulfide” grease that is dark gray in color.

Our MOOG premium ball joints may have a grittier feel to them due to the fact that we do not use a polished ball stud and plastic bearing. And the part reacts differently while it is on the vehicle versus moving the stud with your hand. Our engineers say that this out of box feel is normal. As for the grease, is needs to be lithium based, NLGI #2 grade. Molybdenum disulfide would be used an additive in that case.
