Hello!

I've been collecting suspension parts for my '87 GT, and have noticed something curious about the Moog upper ball joints I've received. They include a castle nut and cotter pin, but have no hole drilled in the threaded shaft. I have also gotten Moog lower ball joints, and they indeed have holes drilled. Am I missing something here, or should I return what I've ordered and seek another pair?

As always, thank you for you help and advice!

Dave

For safety sake, I would return them or at least add another nut as a jamb-nut. You don't want that coming loose.

Thank you for the reply! No doubt, I am sending these Moog parts back if they are not complete. But, what I find curious is that the inclusion of the castle nut and cotter pin make me conclude that there should be a hole to use them properly. Is there anyone else out there using this Moog part? What have your observations been? Also, while the lower ball joints included installation instructions, these uppers had none.

Does anyone have a link to Moog upper ball joint installation instructions? I'm hoping that will answer all my questions. I've been searching but haven't had any luck.

Dave

It's interesting, I looked up the Moog ball joints and none of them have the cotter pin hole nor do they come with the pins. The Rodney Dickman one does come with the pin and hole:


Edit to add.....apparently the uppers don't have the cotter pin. Some have lock nuts instead of castelated. See this thread:

Yeah, my Moogs have the same nut and pin pictured in the Dickman photo, but no hole. I read that thread earlier, but these don't have a nylon lock nut. Its weird, or I'm seriously missing something here.

Thanks again IMSA GT!

No hole in stud? Should have Nyloc nut. Someone screwed it up.
Upper BJ is fine when torque to correct spec.

Reuse nyloc?
Wiki doesn't know either... http://en.wikipedia.org/wiki/Nyloc_nut
If in doubt, throw it out and buy a new one.

edit: don't return it unless it's local. faster, and likely cheaper, to buy a new nyloc

I helped a friend install Moog upper ball joints on his Fiero today.

They came with instructions.

They came with a castle nut and a cotter pin.

They came with drilled holes in the threaded shaft.

I'll check to see if the part number is exactly the same as posted in the heading. (K5292)

A castle nut MUST be used with a drilled bolt/stud and a cotter pin or safety wire. An undrilled bolt/stud subjected to significant vibration should be secured with a prevailing-torque locknut ... nylon-insert, fiber-insert, or deformed-thread type, depending upon temperature and service environment.

Has anyone else had their moog ball joints break ?

Break how?

I am returning these uppers and either re-ordering Moogs, or going with Rodney Dickman's uppers. All my other Moog joints and bushings look great.

Based on the information I have from MOOG part number K5292 should not have a hole and should not come with a castle nut and key. They state you should return them and get the correct part combination.

Yep, the Moog part number we used was K5292.

Maybe we have "old stock" up here in Canada, stuff that was correctly made and packaged years ago.

Every fiero owner should buy Rodney's ball joints and tie-rods. Their simply top quality and you can't complain about the price vs. Moog...

I agree, except that sometimes you can't wait for these items to be ordered and shipped.

Rodney is about the quickest at shipping. You won't be waiting very long.

got to wonder if they are chinese made crap

Rodney is great. However, even his shipping is not as quick as driving to the local auto parts store.

It snapped in half. Like weak metal.
