Pretty sure they are all the same. At least I hope so. I just bought a pair of Camburg UCA from SDHQ their description was for the Taco, but they have the same exact part number listed as the ones for the 4Runner. Haven't installed them yet and other manufacturers may have differences for each model.:shrug:
Supposedly they are the same EXCEPT the BJ base has an ever so slightly smaller diameter than the 4runner/FJ arms. Try to press in a 4runner BJ into a tacoma arm and you will find out it doesn't fit.
they are 99% the same. there would be no gain in swapping to an oem tacoma UCA. youd be better off saving your money for a nice set of aftermarket UCAs like allpro, camburg, totalchaos, ect.
that would make sense for the different pn at toyota yosh thanks, dang cruzado our trucks look very similar, cant blame a guy for trying to get out of spend that kind of money on two control arms...
