    I've always been told the right side of the vehicle is to the right of the driver, so the passenger side. Looking at the part numbers for the leaf springs they are:

    48210-35A20 Spring Assy, RR R
    48220-35020 Spring Assy, RR L

    Assuming the R and L stand for Right and Left, shouldn't 48210-35A20 be installed on the passenger side? Mine isn't, 35A20 is on the driver side.

    For those that have had the TSB done, which part numbers are on which side of your truck?

    I'm 1/2 inch lower on the driver side than the passenger side. I was even before TSB. Gas tank was at half tank when i did measurements.

    The taco does lean.... Is the front suspension stock? If not that's why it's leaning. I'll will check my rear springs for you. Also measure from a completely level ground.

    Front suspension is stock. I measured with park trucked in 2 different spots, both times roughly a 1/2 inch lower on driver side. The "lean" doesnt really bother me just wondering if its because the leaf springs were put on wrong sides.

    Magnum 922's leaf springs are on opposite sides as mine.

    Can anyone else confirm what part numbers they have on each side of truck after TSB?

    My setup after TSB:

    48210-35A20 - Driver Side Rear
    48220-35020 - Passenger Side Read

    Magnum922 posted earlier and his setup is the opposite mine is so I'm still thinking they put the parts on the wrong sides for me.

    Anyone?

    It adds an extra leaf for people having issues with heavier loads.

    Are the 2012's covered under the TSB now? I have tried looking it up but cant seem to find anything. I would like to get it done if it is.

    I am not sure about the 2012's I would start by asking Toyota or complaining to them if you have an issue. I am going to fill up my tank after work to make sure I don't have any lean issues.

    Thanks for the feedback. Looks like part numbers have changed, did a quick search and:

    48220-04211 is now 48220-35020
    48210-04571 is now 48210-35A20

    So your springs are on the opposite sides as mine as well.

    Guess I'll have to call Toyota, thinking they messed mined up.

    Called dealership, confirmed that they did put the leaf spring assemblies on the wrong sides so I have an appointment Monday to get them swapped to the correct sides.

    For reference, the correct setup is:

    48210-35A20 Spring Assy, RR R - Passenger Side
    48220-35020 Spring Assy, RR L - Driver Side

    Thanks to everyone who chimed in!
