Info re: Moog Upper Ball Joints
 

As stated by me and others, Moog's upper control arms come with a serviceable ball joint which can be replaced when needed. Well, I just learned from Rockauto, who spoke with Moog directly, that they don't MAKE a BJ for this UCA nor do they make a replacement boot. WTH?!? This is the main reason I went with Moog in the first place. Their suggestion is obviously to buy a new UCA.

My issue is that my BJ boot is torn but the BJ itself is good so I am looking at the Energy Suspension polyurethane boots. I still need to take it all apart so I can measure the shaft for the correct boot.

It sucks but it looks like the boots are sturdier than the rubber Moog boots.
So...if you are looking for a replacement UCA, make sure they make the BJ replacement and don't assume like I did...

That's always been my assumption with the Moog UCA (that they were not replaceable). I don't think any one makes a UCA for these trucks that have replaceable joints, except for very high end, maybe. The advantage of MOOG is that they have zerk fittings and usually of better quality over oem.

Thanks for that. I've had my 4" Rancho Lift Kit with 35s on for a year now, replaced the the endlinks with Moog ones back then and I think they are already bad! I may just do the UCAs too then.

If you get the Moog UCAs, paint them before installation cause they'll rust and look shabby. As for the boots, I just ordered the Energy Suspension replacements and I'll post part# and feedback after I install them.

Thanks and let me know.

I assume this one is it: (I've already replaced the stocker one twice!)

and bushing (doesn't look as strong as the ones you posted) whenever I need to replace it:

Out of curiosity, what did you spray yours with? I was debating just doing herculiner if that would work there.

So the K80306 is the correct part (left side) but they come with bushings so you wont need those. I replaced the ball joint boots and these are the closest to the meausrements of the Moog BJ:

As for painting, I didn't but I will once my bushings come in. I may just use plain old Rustoleum in matte black.

Wow, that's a huge bummer about non-replaceable joints. Was literally just about to order Moogs since my Camburgs wont fit when I take the lift off. Now what to do...

Don't take us wrong...the MOOG UCA is a top notch replacement for the OEM, even though the joint itself isn't replaceable, it does have a grease fitting. Also, I guess from reading here, there is a better boot available (I'll be waiting for the part # also).

As far as painting them, I had an open can of POR-15 and used that, two years and it is still black and no rust....great paint (coating).

Where did you guys get your Moogs?

Thank I appreciate that. I will definitely consider painting them when I replace them now too.


For Moog parts, I've bought them on Jegs in the past but I plan on looking around for the best prices.

RockAuto or O'Rileys will have probably the best pricing.

I was just at some online site looking at Moog parts and it looks Expensive to buy all the parts I think I need. I may have to just buy all my parts in pairs, as needed, as opposed to just buying everything and doing it all at once. I hate that. Here is the site.

It looks like in your year truck (99) you can replace the ball joint itself. It;s from 2004 1/2 on up that you cannot replace the UCA joint by itself.

Sounds like 2004 is a year to avoid with f150. I have been reading about the breaking spark plugs too.

I have a squeak in something down there and need to replace something pretty quick. I hate noises in my truck

Thanks. They are on the way.
