    Hey Guys,

    I have a 2003 doublecab with a strange balljoint issue that I've never seen before.

    I've installed a set of OEM toyota lower ball joints to find:

    1) The stud tightens to the point that the cotter pin hole passes the castle nut
    2) The joint seems to tighten so much that the boot is mushrooming around the spindle. I only can imagine the lower spindle edge will tear the boot as the truck turns.

    Has anyone seen something like this before? I am assuming the taper of the stud is too small or the taper of the control arm is too loose.

    I'm only assuming this just cant be right...any thoughts?? See picture of mushroomed boot and cotter pin past nut below

    Here is an imagine I found on the forum of another lower ball joint installed.

    You can see how much less mushroomed the boot is and how shorter the stud is.

    Did I get a bad OEM toyota part, or is my control arm NFG?

    Since you are finding the same problem on both sides I'm thinking you have the wrong parts.

    Is it possible they sold you 2nd Gen. BJ's?

    EDIT: You are correct though, somethings amiss there. That boot wouldn't last a few days.

    Did you use a torque wrench?

    There's no way to over torque the right dimension taper to that point.

    Something's wrong.

    Had that been a Chinese knock off, I'd say they just machined a batch too small but for a Toyota OEM....it has to be a wrong part.

    No way the spindle on both sides are that worn or they would obviously be just wallowed out holes.

    hmmm.

    That complicates things.

    May have to do some measuring.

    Where were they bought from?

    What kind of shape were the old ones in?

    As far as I understand there is a version that comes with new bolts and a version without.
    Apparently the physical ball joint is the same.

    with new bolts: 43330-39815 and 43340-39585
    without new bolts: 43340-39436 and 43330-39556

    The "without bolts" part numbers are what was ordered using my VIN number

    According to Amazon these are the right parts. I am interested in this as I was considering purchasing these.

    Correct. 2nd gen ball joints come with the control arms.

    To me, that appears to be the pre-runner lbj

    Edit:
    This part number says it would not fit my 99...maybe something is different on the early tacos? The parts I bought say that they would also fit the later first gens though...so I don’t know

    Pretty sure the pre-runner and 4wd are interchangeable.

    Not saying it’s not an issue with the taper, but I have seen overtightenedd upper and lower ball joints press too deep into the control arm holes from excess torque “I.e. cheater pipe”. When this happens you have to replace the whole arm....

    Do you have a ball joint for a 2wd non-prerunner or non-4x4??

    Am I the only one who sees the description as 95-02 and the op's truck is an 03?
    Or maybe that just pertains to the 4Runner as their 4th gen started in 03.
