wouldn't this be some sort of potentially huge/severe safety issue for the Tc?

you're saying liability for Toyota? no, because they have it listed as part of the maintenance in the book. So they have already indicated it needs to be looked at. Just because the dealers ignore it, doesn't change the reality it should be looked at.


also JOEinSD and cooldrive003, you're welcome!!

Oki so after i get my 2nd free oil change and 10,000 mile maintenance. Is the dealer suppose to do the addition maintenance or was i suppose to ask them 2 do it because thats where they would check all bolts on the chassis... Is it possible for me to still go up there and ask them 2 check it for me cuz this weather sucks...

Mouse Mar 1, 2009 05:09 AM

dude..^^ I would certainly go back in and have them throw it on a lift to check. they know this is a safety thing and should gladly do it free of charge.

AdmirN Mar 1, 2009 05:12 AM

I hope so, ill be going Monday and checkin it out.....

Mouse Mar 1, 2009 05:19 AM

if it is safety related... trust me.... they will do it for you no charge.

I found the nuts to my steering rack casing were loose and one was missing. I'm not sure how long they've been like that. The nuts grip the subframe from the bottom so it's recommend that you torque them from above, though you can sneak a wrench in on the passenger side bolts and hold the bolts from turning. On the driver's side you'll need a ratchet with an extension and a friend to put it down through the engine compartment or wheel well.

Or you can drop the subframe and torque the bolts from the top like the service manual says.

*shrug* maybe you won't find anything when you look, but it's still worth a look.

well i take my car to the dealer since i have my free oil changes but my question is when they do the next one, whats all that i should tell them to check? cuz if i tell them "can you check the bolts to my suspension and steering wheel" they might be confused since im srue there are many. is there a more specific name for all the places that need tightened?

sciontc_mich Apr 28, 2009 02:46 AM

^^ i think that most dealers won't take the time to check them all because they don't want to be bothered. Lazy, I call that! No real name other than "chassis bolts/nuts" like the maintenance manual describes them as. I doubt a dealer would take a torque wrench to each bolt and even if they did, they'd charge you $$$ for it. The other thing they could do is see if all of them are tight/not loose.

kuo34 Apr 28, 2009 03:52 AM

It doesn't take long to jack the car up, plop it on jack stands, and wriggle under with a torque wrench. Sure it'll be dirty and sweaty, but what's the price of peace of mind?

Jasper Ash Nov 18, 2009 05:12 PM

Thanks for the heads up! I wonder if anyone has ever gotten into an accident because of this...

Mouse Nov 19, 2009 12:39 AM

I would seriously doubt it due to that being the root cause alone.
Back on older cars maybe....but with Uni-Body construction that's no longer the case.

sciontc_mich Nov 19, 2009 03:06 AM

^^ actually the problem is that the nuts are not self-locking. It's not about unibody or not. That is why it's advised to check the torque of the nuts. Which means they can loosen themselves and possibly come loose. It's theoretical that an accident COULD happen but I think the driver would have to be really not paying attention to the car, if those bolts were that loose.
