So I purchased some used EX knuckles and I was looking to refurbish them to minty freshness, and that includes changing the ball joint on the knuckle. Now I know that EG/EK/DC Balljoints share a part number that is different from the EF, but what is the real difference in the balljoints? It'd be nice to save 10$ a side if at all possible.

REFERENCE
1991 Civic EX - 51220-SK7-013 - 48.72
1992 Civic Si - 51220-S04-003 - 38.98
1996 Civic EX - 51220-S04-003 - 38.98

 

don't know, but i'm curious too.

 

sure, id like to know too. but id rather just buy the right part.

 

i know that 91 Hf and 90 Da use the same lower ball joint. im assuming either of those would work.

I'm trying to save money through the "same things, different part number", as in the case of the D16Z6 / D16Y8 Metal headgasket. Same thing, but look at the price difference -

D16Z6 - 12251-P08-004 - 48.51
D16Y8 - 12251-P2J-004 - 25.58.

 

I'd like to know too, since I need to replace the lower ball joint on my 91 EX knuckles.

I got old 88 DX, 88 STD, and 91 EX lower ball joints if someone wants to compare dimension(I don't have any calipers to measure them correctly).

 

well i used 91 civic hatchback ball joints on DA knuckles with no problem. So i dont see why you should have a problem with any others. When i bought them the guy that worked at the Dealer said SK7 is used with alot of hondas and acuras and usually means interchangeable between hondas

 

According to Napa, the DA and EF ones have the same P/N, and $47. The 92-00 and DC are also the same, but $22. I will buy the EG/EK/DC ones tomorrow(If I remember, I work right next to a Napa), and let you guys know if it fits.

 

Ok guys....all EF balljoints are the same.

EX - 51220-SK7-013
LX/DX - 51220-SK7-013
HF - 51220-SK7-013

Probably the same for the DA. All I want to know is the difference between the EF and EG balljoints.

I'll try to get pics later(don't have a camera on me), but I just picked it up from Napa. They were out of the $22 ones so I picked up the Napa-brand one for $32(NCP 260-1427 for 92 Civic). Looking at them, the EG ones look narrower and the groove where the snap ring goes is chamfered on the 91 EX one.

 

Final answer: They work!

I initially thought the EG ones were narrower, but I guess it was just the color that threw me off.

Here are quick cell phone pics:

well can you explain for me why i cant use a BFH to pound the old one out and pound the new one in?

 

BFH isnt very sucessful in pounding it back IN. its hard to get it setup STRAIGHT. best to use a press of some sort.

BFH is all you ened to remove it tho.

</TD></TR></TABLE> yes tyson i see what you are saying but if i pound it back in will it damage the ball joint?

 

not really.

but i wasnt able to. i HAD to go get the balljoint press. once its in a good way, i finish it off with a BFH. actually you kind of have to finish it off that way, the ball joint press will bottom out the balljoint and ruin the balljoint. ask me how i know...

 

thanks! i did about 3 ball joints and i think the quickest way was the BFH, not saying the best way but the fastest! i was changing my awd wagon axle yesterday and expletive up the ball joint so i had to replace it with the eg!

I just stuck a socket in between the adapter and the press. worked well.

I was able to swap the ball joint in about 30 minutes; this is my first time doing it. The press makes it very easy.

 

i wish i had a press, my brother is replacing the balljoints for me tomorrow.

i was going to see how much the eg ones were, if they were cheaper i was going to try them, but the ef ones were only 13 bucks cdn per side, so i didnt even ask
