s13 rlca ball joint. B13 or ???

[g14novak]

I've been searching around to see the best way to replace the rear lower ball joints. It seems lots of people just replacing the ball joint with a B13 sentra SER front ball joint. The problem I have with these is that they are the wrong size. The are also 45/each.

I found a site that claims to have the s13 rear ball joint in stock. They claim it is PN#K9633 priced at 19.99/each. MOOG brand. This is different from the one listed in this thread (http://zilvia.net/f/showthread.php?t=135918&highlight=Lower+ball+joints).

A cross reference of the PN shows these are still b13, however, they are not SER ball joints.


Anyone have any experience with these? Itd be nice to save 50$. Thanks!

You need the B12 Sentra front ball joint for rear on S13. #9633 is the correct one.

Got an update. I picked up 2 of the balljoints from carquest. They were able to cross reference the Part number for one they had in stock. They gave me 2 different balljoints. One with a black bottom that measures 38.4mm and a silver one that measures 38.1mm. The silver ball joint was also taller than the black one.

I'm taking the black one back to exchange for another one today.

I was able to exchange the unit with the 38.3 base for one with a 37.9 base that had a grease fitting already installed.

They're at the shop being pressed in now.

Most definitely. I'll take a pic when they're pressed in to show if they have a gap at the c-clip like the b13 units.

i know this is already resolved but for future reference for anybody that looks at this.

I went to O'Reilly's and bought B12 Sentra front ball joints for my rlca's.
I already had the tools to press them in but O'Reilly's lets you rent them for free for 1 day.(in case you don't have the tools)
Just be sure to add a little grease because they're a perfect fit so it'll be pretty tight.

if you're buying, i'd suggest rockauto, you can get them shipped to you most often cheaper than a free standing auto store. Also, even if you're off by 1mm in diameter you will still be fine.

I normally purchase all my parts through rockauto. I had to pick them up locally to have the car done for an event Saturday.

Can back this up. Works on R32 GTS-T as well, did mine last fall.
