    I noticed it after I already finished installing the kit. I wonder if I it will cause any big problems or do I have time to fix it later???????

    So far it rides good. need alignment and tires.

    Front both sides 38 1/4" and rears both sides 39 1/4 " fender to ground.

    You should fix that as soon as possible. Probably won't do any real damage, but they are there to help correct your driveline angles. Did you do both sides the same way?

    looking at your pics, it took a few attempts to see what you're talking about (I ain't gonna lie) - mainly because I was looking at the shortest leaf... are they supposed to bow down like that?

    (try to control your laughter)

    I did a RevTek 3" lift with AAL on my '96 a few years back, and after it was all done I realized I had one arching upward and one arching downward. Drove it like that for probably a year. It's fixed now, but I think I have mine both pointing up...

    Is that right?

    I apologize for the threadjack, BTW. :pray:

    Looks to me like you've got it facing the correct direction. Check the "bjmoose installs OME" suspension link in my sig for details about why I think that and how to measure.

    It is indeed installed backwards. I would swap that ASAP. it shouldn't cause any damage but your pinion angle is gonna be worse than if you had no shim and you'll probably have some vibrations

    I'm really curious as to why you guys recommend shimming a single cardan drive shaft so as to bring the flanges further from parallel.

    That is not what Dana (the driveshaft mfr for US built Tacomas) recommends for their driveshaft installations.

    when you lift the rear of the truck, you are putting the pinion at a greater angle. The shims help bring the angle back to stock. I didn't see in that article where it said not to shim the single carden shaft. Maybe i am just looking in the wrong spot?

    Check page 5. The relevant section is: (CAPS is theirs, not mine.)

    RULE 1: UNIVERSAL JOINT OPERATING ANGLES AT EACH END OF A DRIVESHAFT SHOULD ALWAYS BE AT LEAST 1 DEGREE.

    RULE 2: UNIVERSAL JOINT OPERATING ANGLES ON EACH END OF A DRIVESHAFT SHOULD ALWAYS BE EQUAL WITHIN 1 DEGREE
    OF EACH OTHER....

    RULE 3: FOR VIRTUAL VIBRATION FREE PERFORMANCE, UNIVERSAL JOINT OPERATING ANGLES SHOULD NOT BE LARGER
    THAN 3 DEGREES. IF THEY ARE, MAKE SURE THEY DO NOT EXCEED THE MAXIMUM RECOMMENDED ANGLES.

    A universal joint operating angle is the angle that occurs at each end of a driveshaft when the output shaft of the transmission and
    driveshaft and the input shaft of the axle and driveshaft are not in line. (See Fig 1)

    So, when you shim the pinion "fat side back" you're trying to fix Rule 3 "Keep the angles small" at the expense of violating rule 2 - that "the angles at each end should be within one degree of each other."

    To put it another way, shimming "fat side back" reduces or eliminates the pinion angle.

    Going with a zero/minimal pinion angle is the right configuration for a double-cardan (CV) driveshaft, as seen in this link to Tom Woods' custom driveshaft site:

    http://www.4xshaft.com/double_cardan.html

    But that's not the right configuration for a single cardan driveshaft.

    That is true. however, installing the shim does reduce/eliminate the vibrations caused by increasing the pinion angle.

    Thanks to all for the input. For a Truck rookie like myself I learn some.

    I will fix it tomorrow morning as Toytec recommend in all it is a Toytec Ultimate lift so I should do what they recommend on their product (I did not use the Taco today didn't want to risk anything).

    This was my first time installing a lift kit on a truck, so I kinda overlooked the direction of the shims.

    It was a straight forward install that it took me about 3.5 hours total front and back.

    Tomorrow I will be getting some 285-70-17 prob BFG AT TKO.

    May I suggest that you drive it first and see if you have any vibrations before spending more hours in the garage changing things?

    If you have no vibrations, there's no need to change anything, as the only reason to install, position, or change shims is to eliminate driveline vibrations.

    Looks good to me, but looking at that first pic, one thing you might want to do is install a longer brake line. Looks like it is stretched out a little too much. Maybe just me?? Truck looks good though!:D
