Lower ball joint p/n confusion

Hello, I just recently got a 02 tacoma 4wd double cab that has about 140k. I have no clue whether the lbjs have been replaced recently or at all so I decided to order lbjs from toyota. From what I could find online the correct lbjs should be

$165 43330-39556 Suspension Ball Joint

43330-39556 for the passenger side and

$136 43340-39436 Ball Joint Assembly

43340-39436 for the driver side. I got them and it would seem that the driver side part number is incorrect. See images below of parts:

43340-39436 driver side

43330-39556 passenger side

It might be hard to tell from the picture but the drivers side ball joint has a much more gradual angle for the bracket that goes to the tie rod end. The tie rod bore is also too small to fit the tie rod bolt. The passenger side appears to be normal and looks like it is the same as the one currently on the vehicle.

my confusion is that everywhere online seems to confirm that these should be the correct part numbers, and even when ordering from Toyota they were vin verified as exact fit. I have also seen two other part numbers listed,

$193 43330-39815 Toyota Genuine Parts - Joint Assy, Lwr Ball (43330-39815)

43330-39815 for the passenger side and

$202 43340-39585 Toyota Genuine Parts - Joint Assy, Lwr Ball (43340-39585)

43340-39585 for the driver side. The images on the Toyota site for these part numbers both have the same almost vertical bracket going to the tie rod so my plan is to return 43340-39436 for 43340-39585.

so, can anyone confirm whether I actually received 43340-39436 or is it possible that a different ball joint was mislabeled with the wrong part number and sent?? Internet says the brackets on both sides should look nearly identical except for orientation and I can confirm that both lbjs currently on the vehicle look like 43330-39556.

 

Just pulled my ball joint order from 2020:

$136 43340-39436 Ball Joint Assembly

43340-39436

$165 43330-39556 Suspension Ball Joint

43330-39556, so you have the right part numbers. Where did you order them from?

 

Prestige Toyota Kingston, NY. I’ve ordered a lot of parts from them and I’ve never had any issue before, this seems to be some freak accident

 

I'd follow up with them.

Do you have a caliper to measure the bore for the tie rod? That should for sure be the same side to side. If it's different, then I would suspect that ball joint was mislabeled somewhere along the line.

 

Ok I will call them in the morning and see what the deal is.

just roughly measured them with measuring tape and top diameter on drivers side is 9/16”, bottom is 10/16”. Passenger side top diameter is 11/16”, bottom is 12/16”. So it’s about 1/8” smaller on driver side compared to passenger
