Help Please - lower ball joint hardware

I need the correct part numbers for the LBJ mounting bolts and castle nuts for a 2004 Tundra SR5 V8 EC.

I bought a factory recall set of LBJs, new-old-stock, less hardware.

I've read all the Spiker Eng. test reports and they seem to be for '96 to '02 4Runners. Plus I've spent many hours trying to find the right bolts for an '04, but there are too many conflicting numbers that I have had no luck knowing which ones are the correct numbers.

Those two threads from the sticky thread section here on the forum are what you need. 2004 is a crossover year, which means there was a change in part# mid-year. Nobody on this forum will be able to give you better info on this than, say, your local dealership’s parts counter. But the 2nd of those threads will point you to the part number directly using the first few gullet points. You’ll find it in the Chassis section, under front steering knuckle, which will be a little more than halfway down the list in the 2nd picture at the EPC site.

This is one of those rare times when I’d tell you NOT to put the onus of getting the right part number on a random internet stranger. Call your local parts counter at the dealership nearest you OR call Ourisman Toyota and confirm with them before you order from them. Sadly, you just missed the 25% off sale with Toyota nationally. It ended Sunday night.

 

I think they just started another 4 day 25 percent off special. I ordered tie rod ends this afternoon and it was the 25 percent off, free shipping over $75.

 

Yup. Screenshot from just now.

 

For 2004 Tundras, the answer is pretty straightforward depending on whether you have the 14 mm or the 17 mm bolt heads and spindles. If you have the bigger ball joints with 17 mm bolt heads (throw a socket on it) then they should have been replaced under Special Service Campaign (SSC) 70B using the exact same LBJ replacement kit as the 05-06 Tundras. That kit was Part No. 04006-62134.

I am curious as to how you got a recall kit without the castle nuts and cotter pins included???

I replaced my LBJs in the fall using the same LBJs and bolts as the 05-06 crowd verified by Toyota South (TSR) and Toyota Knoxville (TKN) Parts Staff. There are 3 different bolts that can be used on the 17 mm big.LBJs. I have two of the bolt part #s in front of me since I ordered both sets. They are:

90105-A0187 Flange Bolt [Alternative]
90105-12316 Flange Bolt [Primary]

Here is what they look like side by side compared to the original bolt at 222k. From L to R:

1) 90105-12316 - More polished appearance with heavier coating of factory red thread locker.
2) 90105-A0187 - Less polished appearance, lighter coating of red thread locker, a single thread longer, and appearance very similar to original LBJ bolt. This is what I am currently running on my 04 AC.
3) Original Bolt off production line assuming the bolts were re-used during the LBJ replacement at 50k under SSC 70B instructions.



One note of caution, the TMC Autoparts site was a hot mess and listed a limited production ball joint that I was not familiar with and didn't make sense. I have those different part #s in my notes but not listing to avoid confusion. Also, if you log into Autoparts by VIN or Yr/Model and select a dealer it carries the faulty LBJ part #s over to the dealership site. For fun and games, I checked the EPC parts site linked in the Parts sticky thread and it also lists some strange part # that is not correct. Go figure.

Again, independent Parts verification by three different Toyota Parts Departments yielded the mounting bolt part #s listed for these 17mm LBJs that I installed:

43340-39595 Lower Ball Joint Assembly Left Hand with Knuckle Arm
43330-39825 Lower Ball Joint Assembly Right Hand with Knuckle Arm

These came equipped with the Lower Ball Joint Dust Cover Protector (43346-34010), so no need to order separately. The assembly also included the castle nut and cotter pin so I never bothered to look up those part numbers either. Maybe someone else with the 17 mm bolts can help you there.

Edit: Ourisman Toyota (OTR) correctly lists my LBJs by VIN and identifies the castle nut and cotter pin part #s for the 17 mm LBJs listed above as the following:

1) 90171-18003 Lower Ball Joint Retainer Nut (2004-2006 Tundra)
2) 95381-03225 Lower Ball Joint Cotter Pin (2000-2006 Tundra). Note: There is a misprint in the SSC 70B Parts List that shows this as the castle nut. Also the bulletin identifies this part for CPs as:
3) 90252-03015 LBJ Kit Cotter Pins

I have some info on the 14 mm, including SSC 50J if that is what you have but obviously not what I needed or used. If you have the smaller LBJ, best to check with a dealer.

 

This info is awesome should be in the LBJ sticky thread.

Recall kit - all I've seen at least - are just the bare joint and rubber guard bolted on in some (or possibly all) cases. No castle, no cotter. Did you order a recall kit and get castle + cotter? Bare joints come with those extras for sure. Just haven't seen the kit come with it.

 

I bought this kit from Ourisman in September 2024 for my 06 DC. It only came with the two LBJ's and 4 cotter pins. Ourisman stated that's what it comes with.
I bought the nuts and bolts separate.

04006-62134. Both lower joints. No castle nuts or bolts.
90105-12316. Bolts
90171-18003. Nuts
2 of the cotter pins fit the tie rod ends but the other 2 were kind of small for the LBJ nut so I used a bigger one.

 

From what i am gathering, the "KIT" was what they sent the dealers for the recall. This was for the trucks when they were relatively new so Toyota planned on the dealers reusing the castle nuts. 04006-62134. Both lower joints. No castle nuts or bolts.

You can buy the LBJ independently and they come with:
43340-39595 Lower Ball Joint Assembly Left Hand with Knuckle Arm
43330-39825 Lower Ball Joint Assembly Right Hand with Knuckle Arm
These came equipped with the Lower Ball Joint Dust Cover Protector, castle nut, and cotter pin.

 

At this point does the OP even know if he has the right ball joints because wouldn't that coincide with the smaller or larger bolts?

 

They make two types in the same diameter/length. Grade 8's (I think) and some others with washers, not sure the grade.

 

Guys, the recall lower ball joint kit I bought was from an eBay seller. From what I've read above, those kits did not have castle nuts, cotter pins, or mounting bolts. I got Toyota 43330-39825 and 43340-39595 LBJs.

I'll check the original mounting bolt head size when the weather clears up again.

Thanks for all the feedback, especially from TnPlowBoy - GTREAT write-up!

I have one more question, ugh, I know, as the two LBJs arrived today... Why do the LBJs have two upper holes with what looks like extended shims that stick out lower than the face of the other side's machined bolt head faces?
Are they positioners for RH and LH?

 

Dude. Never. Ever. Ever. Buy parts on fleaBay or scAmazon. Counterfeit/knockoff hell on there. There is ZERO legitimate reason to ever buy auto parts on either place. How do you know the parts you got are -00% authentic, and who are you going to go after for damages if they’re not, and fail?

 

Those are to center your part so the holes line up properly. You’ll understand when you install.
