Attention!: Regarding tC chassis bolts (By sciontc_mich)

    If you look in your manual it will say "Every 5000 miles check bolts/nuts on body/chassis". I've talked to different Scion dealers and no one says it's necessary. nAnd the Scion dealers don't really seem to care, don't think it's a big deal. They couldnt be further from the truth! Did a little more digging for info and found out the bolts that the manual is talking about are the suspension bolts!

    So I went out to the car with an accurate torque wrench and thought I would see if the bolts were tight. I do have the service manual, so yes I know the correct torque setting for all the bolts for the subframe and suspension.

    What I have to tell everyone is this. A lot of the bolts were loose! On one bolt in the rear (this is why I'm posting this) is the bolt that holds the hub (brakes, lug, wheel bearing) to the suspension. I got about 3-4 turns out of that bolt. I am just wondering, okay let's say I didn't check it, and it continued to loosen, it would come to a point where it would seperate from the suspension! Toyota did NOT use locking nuts on these bolts, otherwise you wouldn't have to re-torque them every 5000 miles.

    I just don't want my fellow tC-ers to be in danger when I just have seen it twice so far on my own tC. It wasn't the factory, these things are getting loose on their own and I'm not driving on rough roads!

    For everyone else here, please get these checked. Relief



    UPDATE: For those who are going to check on this, you'll need the right tools and the right info

    Here is a link to the files you'll need to read for the correct torque settings:

    1- Front Suspension - http://www.mediafire.com/?zqbexjdijm4
    2- Power Steering/Front Suspension - http://www.mediafire.com/?j4eyxz41g5o
    3- Rear Suspension - http://www.mediafire.com/?tcmimnzn20h

    Tools needed:
    Jack Stands and jack
    19mm socket and 19mm wrench (boxed and open for all)
    22mm socket and 22mm wrench - for the front strut mounting bolts
    17mm socket and wrench
    14mm socket and wrench
    Torque Wrench that goes up to 177ft-lbs (for the front lower strut mounting bolts)
    thats some good info thanks for the info
    Probably in the small print somewhere in the 30 pages I signed when I purchased my tC.Good read,thanks for the info...
    scary....... ty for the warning brah...
    Yup, better check your shit
    I suppose I need to do this.

    As my tC has seen more off road driving than most.
    By the factory standards, that is probably an acceptable amount of missing bolts from the chassis. lol
    good write up, will be doing this for winterization.
    damn now i gotta check mine i'm on 14K miles. thanks for the info big time
    I'm at 62k miles and no problems. Though, I have tightened all of the bolts before from doing the spring/sway install.

    I appreciate you passing this along to Club Scion tC members, but you could have said that your direct quote was my post from Scionlife.com. Not trying to start a flame war here, but please give credit where credit is due. Like my time under the tC with the service manual and a torque wrench. Thanks.

    yeah i spent a lot of time under the tC with a service manual and a torque wrench, must've been a couple of hours deciphering the many torque specs for each bolt. looks different as you're laying on your back looking up! lol yeah I don't fault vicious for being anxious just that he can credit me the quote.

    glad to help out fellow tc'ers! It amazed me that the nuts/bolts were able to be tightened! They're not kidding in the manual when it says "tighten bolts/nuts on chassis" in the owner's maintenance schedule! But the dealer always just passes by like it doesn't matter. but it does.
    i still have to check mine...havent had a chance...hopefully ill be able to get around to it sometime this week..weather has been horrible

    any other nuts/bolts/screws...that we should know about? lol wat other information have you come across while working on ur car
    I usually link to the original thread where I obtained the information, sorry mich, I dropped the ball on that one
    And for you sciontc_mich you deserve this:

    I just wanted people to know where they could come if they needed questions answered about what I found out. No problem! peace
    So is this a problem with later tCs? This thread doesnt seem like it originally got the attention it should have if this is sich a huge problem.... Is this something that everyone is doing?
