Need quick help, replacing rear shocks on 2011 Limited 4wd

[Michael Mandry]

Hey everyone, first post here. I am in the process of trying to change the rear shocks on my 2011 Limited 4wd (without air suspension). I am trying to remove the bolt/nut through the shock in the lower control arm. Chilton says torque is 406 ft-lbs. I am using a 1/2" impact rated to 650 ft-lbs. And PB Blaster has been sitting on it for hours. But it will absolutely not move!

Any suggestions?

Get a long piece of pipe on your 1/2 ratchet and go to work.

If that impact isn't doing it, I'd look into applying some heat and a whack with a sledge. Hope you get it going.

Thanks guys. I gave it some whacks, I sprayed more PB Blaster and let it sit, and kept working on it. Finally gave!!!! Now on to the next steps!

406 ft/lbs of torque!! Ford certainly don't want it coming undone accidentally!!

They also want you to replace the bolt and nut every time it's removed, in case Chilton doesn't say that.

That's why I bought the big boy Milwaukee impact. I'm so tired of fighting with bolts like this and this makes 406 ft/lb easy. I tossed around the idea of buying one of the mid torque models and figured I'd regret it. Considering I'm doing my rear shocks soon I'm happy I bought the big boy. Also bought the rubber boot so I don't beat it up too bad

Nice impact wrench, all of mine run on compressed air, they work great but you need a big compressor as they really consume air when working!!

I've always had pneumatic tools and not having a garage makes air tools a pain so I sprung for the Milwaukee. They claim 1400lb of nut busting torque and Its pretty powerful

1400 lbs/ft from a portable electric wrench, that is fantastic, I think I might have to take a serious look at getting one!! better stop here before I get accused of hi-jacking this thread, but thanks for the info.

The 1/2 Milwaukee is a beast. I have the 2763 M18 Fuel. It specs 1100 lb-ft nut busting. It will snap a seized wheel stud off a Subaru with little effort.
Also, I second PB Blaster. That stuff is great. Gotta let it sit though.

406 ft lbs!!!????? That's the lower control arm main bolt to frame Right?

I'm going to be doing a Rancho quick lift strut system soon and need to know where to get all the torque settings. Got info???

 

[deweysmith]

Nope, lower shock to control arm bolt. Lower arm-to-frame is only 166 ft-lbs.

That bolt would have to have a thread of at least 20 mm or greater, to even support such a ridiculous high torque spec. Sorry but you read something wrong, I'm not there to see the size of bolt diameter. My guess is its probably 12-14 mm thread coarse with a 17 mm head. Maximum torque would be 100-140 ft lbs depending if its 12 or 14 mm thread_ just like the lug nuts. It would take a 3/4 or 1 inch drive breaker bar to even get close to 400 lbs torque. No not that bolt your describing, Had to be a misprint from Ford. In the future, if your not sure how tight a bolt must be, measure thread/pitch, look online, or back of any repair manual, it will tell you the safe torque. That's just basic mechanics 101

Surprised that the impact didn't do it the first time...I just did my rear strut assembly a couple weekends ago as well...it wasn't too difficult, just more steps and more tools than a typical shock absorber swap... I think I used a 30mm socket (or close to it) to remove, I just remembered it was a big sucka..

What are your wrists rated at?

It actually doesn't hammer on your wrist as bad as some might think. It's actually enjoyable to use but love tools and work with them everyday. Someone who doesn't may struggle with it a littke bit
