Torque LCA nut next to muffler
For the 80 series guys-how do you torque the nut for the rear lower control arm on the muffler side where it attaches to the frame? It's 130 ft lbs and you can't fit anything other than a box wrench or a crescent on that nut. Any tricks?

I've had similar issues on nuts next to the gas tank on the 3rd gen runners. I torque the other side, then feel how hard it is to just get it to turn with the box wrench (usually with a cheater as well), and then feel it out on the other side. I use plenty of loctite, and it has never been an issue. Probably not exactly 130, but close enough for the loctite to take care of the rest.

I also don't know if the 80 series are the same, but on many pieces of the suspension, there are indexing tabs on the nuts, and indents on the frame, which allow the nut to "lock in" when it is at the correct torque. Those also help prevent loosening.

80 series nuts are indexed. Torque the bolt side.

Thanks for the comments. I'm using brand new hardware, and the bolts have the serrations instead of the nuts. I may just go as tight as I can on the nut, and then do a quick check on the bolt and see how close I am.

weird, I just got new hardware too this fall and the nuts had the serrations like my originals? Reverse the direction of the bolt so you can get a socket on the nut end?

See now that's the kind of obvious and logical thinking I wasn't bringing to the table. I was just putting it back like Toyota intended it to be, but flipping the bolt around should allow plenty of room to crank the nut.:homer:

Now post up a pic of three different 24mm wrenches and ask us which one to use. :)

You can also use the handle of your hi-lift if you need a longer wrench for leverage... If you want to put it back the way Toyota had it.

Well now I remember why I couldn't reverse the bolt - the same reason I couldn't get a torque wrench on the nut. The muffler is so close to the frame mount you can't fit a socket up there, so a 4 inch bolt is out of the question.

I just grabbed the longest wrench I have and gave it the "full body torque." It should hold.
