Full disclosure. I’m not the sharpest beer in the fridge but Toyota is giving me a headache. In hindsight I should have just taken this to a mechanic but I’d like to learn and I’m neck deep in this mess so I gotta solider on. I plan to have my local mechanic check my work when I take it in for an alignment but I gotta get this rig mobile first. Lol I’ve been dinkin around with this for a few days and kept getting pulled away.

2001 Sequoia 4x4 Limited Lower Ball Joints. I got all my parts in finally and started the lower ball joint replacement with OEM Everything.

They sent me two different sets of bolts.
4 - part # 90105-10505 silver bolt with attached flange and red loctite already on it.

4 - 90119-10933 a black bolt with a unattached washer and no loctite.
these were purchased from one of the closest Toyota dealers from me which is an hour away.

The bolts I’ve taken out of the old ball joints are all like the silver washers with the attached flange. They do not appear to be stretched and these old lower ball joints appear to be OEM ball joints. I don’t know their age and Ive had the vehicle for just over 100,000 miles and 9 years so I’m changing them.

The dealer is adamant that these two bolt part numbers are the only two for this part but he can’t tell me which holes the respective bolts go in or why there are two types of bolts.

What I THINK is that the black bolts go in the two holes with the raised alignment flange on the LBJ itself. (See pics). The black bolts have 2 marks on them which I believe is grade 8? The Silver bolts have 6 hash marks which I believe is grade 6? The black bolt is slightly longer than the silver.

Any assistance is appreciated.

Match them up to what comes out?

I should add, I know someone who was replacing a A/C compressor on a Lexus that had trouble with the bolts. He didn’t realize they were two different lengths. Tightening one of the bolts damaged his block because he installed them in the wrong holes on the mount.

That’s just it, the ones that I took out are all the silver ones with the flange. The black ones the dealer sent me are the odd man out with no direction on why or where they go. The dealer just says, “those are the right part numbers”.

And that’s just the kinda luck I have sometimes so I always like to check if I can’t find the answer with the google machine.
 
And if I can hijack my own thread, what would be the best service manual to get for these older Toyotas? Chiltons?
 
I don't have much to comment but I had a 4Runner with a similar lower ball joint design which is really bad. Toyota messed up big time with regards to designing the suspension geometry such that the lower ball joint is under tension instead of compression. Means that when they wear out, the joint pulls out from the socket suddenly without much signs of something being wrong beforehand.

So pretty important to get this right! With the 4Runner, there was a discrepancy in the service manual over the torque spec, which is pretty critical.
