Is it okay to loosen the Jam Nuts while the control arms are on the jeep?

 

Yes indeed. In fact it might be your only way to get enough leverage to do so.

 

gotcha is there a special type of wrench to be able to set it up at 220lbs? I have a torque wrench for the bolts but not the jam nuts

 

A couple ways to do it. If you have a torque wrench that goes that high, you can consider investing in a set of crows feet. They can be awkward to use but will get the job done and you'll know it's torqued to spec.

On the other hand, many will tell you to just put an adjustable wrench on the jam nuts, put on your big girl panties, and go to town. In other words, tighten the bejeezus out of them as best you can.

 

Option 2 sounds more fun i will do option 2, option 1 looks similar to using a torque wrench with an armorers wrench for ar15s

 

I have never heard of anyone over torquing the jam nuts I have heard of someone popping a nut tho on these bad boys lol.

 

Crows foot and breaker bar

 

I'll usually use a large pry bar to keep my joints nice and even, not canted on the mount.

Jam the tip of the pry bar in between the joint head and the axle or frame mount. Stays in place and gets tight without swaying the joint.

Maybe it's odd I just use a 20" crescent wrench with the pry bar trick till I scream. I check them all the time, not once loose.

 

Was that from Goody? The pic looks familiar and I've got a few of these that I've been asked to double-check.

 

Amazon.com is where I got mine.
