Torque Specs for rear shocks

Anyone have torque specs for rear shocks? replacing mine now need upper nut and lower nut spec. Its a 2001 Tacoma 4wd V6 Bilsteins 4600

 

From 2003 FSM:

4WD and pre runner: 71 N·m (730 kgf·cm, 53 ft·lbf)

 

Is 53 for the upper or lower bolt?

 

Both, same bolt size I believe

 

Hmm...I just tightened mine as tight as I could with my wrench and used some blue Locktite on them. They haven't come off yet lol.

 

Same here! Tightened them as tight as I could get them. Been fine ever since!

 

Nothing like the ol gutentite 1/4 turn from being stripped lol. 53 ft lbs for suspension related bolts isn't too much even if top and bottom aren't exactly the same. I'm assuming they are though. I think 2nd gens are 75.

 

This is why that's a bad idea:


Toyota sets torque specifications for a reason. And Murphy's law guarantees this will happen only when you're far from home.

Jesus man, did you use like a 4’ breaker bar on that? Unless you’re He-Man or giving yourself a hernia trying to tighten it, I don’t think you’d get enough torque to snap a shock bolt from a box wrench.

While a torque wrench is a good idea, I’ve never brought one on the trail. “Putting it on as tight as it was getting it off” is usually good enough, especially for a trail fix. Get home and fix it proper, with torque specs.

 

Pic looks familiar lol

I don't think @eon_blue is applying stretching-the-bolt-to-near-failure amounts of torque. Once someone puts on enough aftermarket parts on a truck there's no more specs to follow unless you want to go with a general spec chart for bolt size. I was trying to get some torque specs for the bolts on my Solo suspension kit and was told "I have one of the younger guys get on it with a breaker bar." Yep lol.

 

That wasn't my bolt. But I've over-torqued bolts before and had them break. If you get the bolt too tight, the truck will add torque in certain situations and the bolt can break like the one in the photo above. Those situations would likely be when you're off roading and the suspension is under extreme stress. You might not ever have a problem, but those torque settings exist for a reason.

 

Pretty sure a M10 shock bolt that doesn't hold any tension and goes into a blind hole single shear isnt going to be flexing to the point of breaking. Torque specs exist for a reason but so does common sense. If you need torque specs for this bolt you are probably overthinking the whole thing haha. I've yet to hear of this mythical bolt snapping after effect on something as mundane as minitruck suspension, usually you know right away when you've torqued to full yeild, your tight bolt just suddenly gets nice and loose.

 

Yeah, you're probably right. It would probably be hard to over-tighten one of these bolts to the point they will break and fail. But just wrenching down on bolts as tight as you can get them isn't really a great practice.

 

Right you just want them Gutentite

 

I am the weirdo who reads the manual. And it seems the more I learn, the less I know...

 

Snug with never seize .

About all I have ever torqued is engine work Head bolts Rod and Main Bearing bolts fly wheel

 

It’s not about tightening them as tight as you can get them. Contrary to how my father did car repair, it’s not a strength competition.

We aren’t talking about torque to yeald bolts, like head bolts or other critical engine bolts. These are shock bolts. The only thing over tigtening these bolts will do is make it a little harder than needed to remove them.

You turn enough bolts and you start getting a feel for how tight they should be. With a lot of bolts, you can judge by how hard you had to work to get the bolt off.

 

I should have been a little more specific, I meant as tight as I could get them relative to me laying on my back looking up with maybe a foot of workable room to turn the wrench...definitely not using all of my strength because there simply wasnt any feasible way to do so...but as tight as I could get it in that situation. Certainly nowhere near tight enough to over-torque the bolts. If anything, I'd be afraid I under torqued them.

I've since picked up 2 torque wrenches though because I had to work on my LBJs and my u-bolts and I know how critical those numbers have to be. I almost always use a torque wrench now if I can get it to fit in the space I'm working in, along with blue loctite if it's something that could spell disaster should it come loose.

 

If nothing else, it’s a good reason to get a new tool.
