just curious why that is. have an 2009 Camry SE and when i did my front strut assembly replacements the torque values were much higher on the front ones than the rear ones (at least according to the youtube videos i watched)? For example, the bolts that hold the strut to the knuckle, on the front i think the torque was around 155 ft/lb but on the rear its 133 ft/lb. same goes with the sway bar links and the top nuts that hold the assembly at the top.

The front wheels being the drive wheels, and being subjected not only to greater direct forces but lots of other ones related to the fact that they move (as in steer) compared to the rear would be explanation enough for me.

Agreed 100% plus the fact that you have the weight of the engine and transmission and as you stated all of the moving components that you don't have in the rear.

that makes sense. i thought about that too, but why not just make both ends equal? would it be bad if i torqued the rear to the same specs as the front?

You never, ever want to torque anything beyond the manufacturer's recommended specs.

The engineers that came up with them really did so for a reason (or many reasons) and overtorquing is just asking for fastener failure.

As others have indicated, seems logical given that well over 60% of a Camry's curb weight is sitting up front, and the front's the end that does all the work in these cars. I wouldn't mess with the torque specs.

I recall the bolts that go through the knuckle to hold the strut on, are a bigger diameter on the front than on the back. (Or at least they have been on other Toyota's I've done struts on).

So of course you torque them higher.

Most all the bolts are bigger on any given car's front suspension than rear suspension. (Maybe not sway bar links etc.). You might notice that front struts and spring and mount are also bigger than on the rear. And more expensive.

The rear parts may be made lighter as they absorb much less stress and cannot be torqued like front with out failure, or stripping. Trust me on this one thing, the guys that design and engineer mechanical things know more than any mechanic or you tube video person, follow their standards no one else's. if the engineer who designed a machine says do this, then do that, there may many reasons other than material strength and load stresses they are taking into account, but they know more about their product than anyone else, they designed it.

that's awesome. thanks so much. you wouldn't happen to have the ones for the rear as well would you?
