Default How To Deal With Really High Torque Bolts

I've been working on my car on my own for a while now, and an upcoming mod has got me worried. I'm used to working with bolts requiring up to about 70 ft-lbs of torque and have since acquired a torque wrench covering 10-70 ft-lbs. However, some of the bolts with which I am about to deal have a spec of 168 ft-lbs. How on earth do you a) get them loose when you're jammed under the car and can't attach a 40ft long pipe to your breaker bar and b) torque them back to spec? I can find a torque wrench that is affordable by mere mortals (NASA maybe) that will go that high. So what am I supposed to do?

Use a breaker bar to remove them (I replaced the rear transverse link bushing on my car - used a 1/2" drive, 18" breaker bar to remove the bolts to the frame (180 ft-lbs), then a box wrench to remove the nut holding the bushing to the control arm (used leg power for that one since the wrench is much shorter - torque spec is 140 ft-lbs)) - torqueing things back down - well, for the nut holding it to the control arm, since I couldn't get a torque wrench on there, I just put it on really, really tight using my legs. For the bolts to the frame, I have a 1/2" drive torque wrench (craftsman) which is 25-250lbs, so I used that. Not a problem (as an aside - we don't really have a road salt issue down here, so rust wasn't a problem - for you, I would make sure I hit everything with pb blaster and give it some time to work first)

Hitting wrenches repeatedly with a large hammer often works. It can be very hard if you can't get a socket and bar on there. The Sears torque wrench is not too bad - http://www.sears.com/sr/javasr/produ...id=00944597000

The Sears wrench looks nice. Definitely a contender. However, I'm planning on doing an alignment at the end of this. That means the car will be on the ground and I'll still need to swing the wrench. I think that's definitely too long. Any other options?

Most of us "pro shadetree" guys use the "Gorilla method", which is a scale of 1 to 5 gorillas. 1 being exhaust, 3 being lugnuts, and 5 being suspension bolts. a wrench + dead blow hammer is a terrific tool, otherwise you need some cheaper pipe to create leverage. A dead blow hammer is the "torque wrench" of hammers as that shot flying around inside the hammer multiplies the force by about eleventy billion. I wouldny stress too much about specs, as long as you tighten the hell out of those big suspension bolts, you'll be alright.

I never claimed I was using a torque wrench to break bolts loose. Why would I do something so stupid? It's a precision instrument. In fact, in the OP, I mentioned that I have a breaker bar.

So just banging a few times on the end of a 24" breaker bar is sufficient to prevent keystone cops moments of wheel separation?

Oh. Dear. GOD.

I don't have the words.....

The most amazing part is that it's actually kind of a good question from a mechanics (as in physics) perspective. But the answers.....

There were some good suggestions, and I'm pretty sure some of the bad ones were jokes.

I thought impact wrenches always banged away at their maximum rated torque. Can they be turned down to a precise setting?

Sheesh, nobody noticed the nut on the bottom huh?

Pretty much any 1/2" drive torque wrench should go to 168 ft/ lbs. And you should be able to produce the amount of force needed to achieve the "click". IT's alot, but your a man right?

No offense ladies.

^^Read more carefully. Applying torque to the nut is easy; the problem is keeping the ball from rotating along with it.

impact socket head, breaker bar. start with a gentle kick. if that doesn't work, hit it a little harder until it does. works well with eccentric bolts

wow, you know, I think I've seen this discussion in another thread. Could it perhaps have been in the thread initially discussion the hitch problem?

from personal experience: was taking off exhaust from a fellow subby owners car, the bolts were so rusted that they wouldnt bugde, after about 1/3 bottle of pb blaster i tried a new technique. . . i put the pipe around the wrench and carefully lowered the car untill the cars weight torqued and broke the bolts.
- not the best way to do it, but when you have limited choices you make it work.
