Spiker Engineering Lower Ball Joint Bolt Test (1st Gen)

It's been a while since I checked on this thread, and I see a lot of back and forth on some of the torque values thrown out, hopefully all the questions have now been answered. If not, please let me know.

I saw a couple of references that the "red" bolts come with red loctite - that is not the case. The red is just an identification color, it is not in any way a threadlocker. So please don't count on it to keep the bolt from loosening.

Also, a small update - we found that the ARP bolts do not hold up well in use - they corrode pretty quickly, because they are only black oxide coated. It may not be a big deal in CA, but for anyone in the rust belt, they will rust quickly (see below, less than one year of use in St. Louis). We're about to test a stainless steel version of the same bolts, I'll report back once we have that data.

Maybe this rust is the best red loctite!

Here's the part number for the bolts I used that should also match your '06 (17mm).
Flange Bolt - Part Number: 90105-A0187, Qty:8

Are you certain these are the same as 90105-12316? Pulling them up on the SerraToyota website shows something different:

Nevermind on this one. Looks like it's been addressed and I just missed it:

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.
