    Mine don't squeak either after about 8 months.

    Oh wait. They're still in box waiting for my dead ass to install them.

    How many miles in those two years they lasted?

    The JBA UCAs look interesting. I have about 43k miles on Total Chaos UCAs with stainless uni-ball. No squeaking.

    not sure of the actual measurement. But i have right around 1/8th of an inch of toe in (the difference between the rear and front of the tire, front being the shorter of the measurement )

    Awesome^

    Back on topic.

    Does anyone have any measurements on say a 1 or 1.25in uniball upper as far as angles they can do? From what i am reading a 1inch uniball maxes out around 70* This would mean the JBA arms actually have MORE flex than a uniball setup.

    A uni-ball UCA can accommodate travel of an extended travel coilover. What coilover would need MORE than that? Thus no benefit, even if that is the case.

    all the extended coil overs on stock length upper and lower control arms require them to either be internally limited or strapped to not top out the uniballs.

    OK, I'm really confused - but that is my usual state when it comes to suspensions. So please be patient with my cluelessness and likely misunderstanding. And by misunderstanding, I could either be misunderstanding how our suspensions components work or I could be misunderstanding your post!

    Here's what I thought to be true about the stock 2nd Gen Tacoma Front IFS Suspension for 4x4:

    • Compression/uptravel limited by bump stop in stock configuration
    • Droop/downtravel limited by shock in stock configuration
    • Stock UCAs have slightly more droop/downtravel than the stock shock
    • Stock LCAs have significantly more droop/downtravel than the stock shock
    • Droop limited first by shock, then UCA and then LCA in stock suspension
    • The stock UCA is not designed to limit downtravel and installing a shock with more than stock droop/downtravel could damage the stock UCA ball joint unless you use a limit strap to protect it.

    I could be wrong about any of the above, did I get all of those correct? I'm least certain about the last point in the list, can someone confirm that?

    Next please confirm these points about modifying the suspension:

    • A variety of both standard ball joint (LR, JBA) and uniball (TC, Camburg, ICON) UCAs increase the mount of droop/downtravel that the UCA can provide. The stock LCA already provides more droop/downtravel to accommodate these aftermarket UCAs.
    • If you have an aftermarket UCA that allows more downtravel you can use a shock with some modest amount of extended downtravel without needing limit straps or stressing/breaking the aftermarket UCA ball joints/uniballs.
    • ICON "extended travel" coilovers actually have the exact same body length and piston as "standard travel" the only difference being a longer spacer/stop in the "standard" which limits downtravel to near the stock specification. In the "extended travel" the spacer is shorter to allow a little less than 1" more droop. The aforementioned aftermarket UCAs and the stock LCA can safely provide for this amount of additional droop without damage.
    • If you want even more suspension travel you would need to install physically longer UCAs and LCAs, the longer arms allow for more vertical travel in inches when the arms move through the same angular arc. This would require different shocks and springs for coilovers as well probably.

    Did I get all that right? (It would be amazing if I did).

    And finally, your post. It sounds like you are saying that extended length coilovers will break any UCA that is stock length - including things like LR, JBA, TC, Camburg and ICON - unless the travel is limited somehow. That doesn't jive with what I've written above or with the kits the Wheeler's provides combining ICON extended travel coilovers with the UCAs I've mentioned above which I thought were all stock length UCAs just with more articulation from their joints.

    So it seems like I've got something wrong someplace! Maybe the most likely is I'm just misunderstanding your post, but I honestly really don't know if the things I've written above about the suspension are correct - so if I've got something wrong there definitely let me know!

    You hit the nail on the head on every single point!

    When i was talking about internally limited or strapped i was talking about say using an 8inch shock (typically used on LT setups) vs a standardish length 6inch shock

    I do know for a fact that my 5100's are limited by the stock UCA ball joints topping out on down travel quite a bit.

    I'm amazed! I've pieced that together from reading so many different posts it seemed likely I'd have something wrong.

    Ah, thanks! I misunderstood what lengths you were referring to. Makes perfect sense now.

    And thank you for taking the time to read that long post and confirm I was understanding things. It is a big help as I'm getting ready to do my suspension in a few months and want to make sure I understand what I'm doing!

    I will say even with a TC upper control arm with the 1.25in uniball running the "extended travel fox / icon" stuff will get REAL close to maxing out the uniball itself.

    You seem fixated on comparing uni to bj articulation differences. Is there actually a coilover available that allows enough droop to go beyond the amount of flex that an aftermarket UCA provides?

    There was a TW member just above me in here in the 805 that snapped the main bolt at the uniball / spindle because it would droop and top out on the uniball....

    So you're providing a public service then? Do you know what their set up consisted of? Any links to pics etc? We should know details if this is a issue of concern.

    Alls im saying is keep an eye on your setup as everyone is different. I know the 5100's get TC ucas pretty close to max extension.

    Im still waiting to hear back on how much degree of flex the TC uniballs have
