My Lower Control Arm Bolts Were Loose

In the past few weeks, I've felt like something was loose in my front suspension. It drove and rode fine but whenever I'd hit a bump, it would just have the slightest 'clang' feeling to it. During the last couple of weeks, I've been checking bolts to make sure everything was tight. I checked my lower ball joints, the top strut mount studs/nuts, lower strut mount bolts, etc.
Well today, I removed my skid plate and checked my LCA bolts. The passenger side front was tight, but the other three were loose. They weren't REAL loose, but I could tighten each of them about another half to 3/4 of a turn.
I replaced my LCA bushings and had the front end aligned about five months ago. I had to replace all the hardware and went with OEM Toyota bolts, sleeves and alignment cams. I greased everything before reassembly, and welded up my alignment tabs.

I don't have a torque wrench that goes high enough, but just tightened them with a 2' cheater pipe on a good ratchet. You can feel when they seat and the bolt is beginning to stretch.

I marked each of the cams and bolt heads and nuts and will keep an eye on it but have others here had the same problem? I know I've seen other threads on this but I'm surprised it happened to me. If it happens again, I'm considering 'staking' the threads on the bolts just behind the nuts.
Has anyone come up with a solution other than checking them periodically?

 

use a torque wrench and this

Happened to me too after an alignment. Those LCA bolts need to be torqued to 100 lb/ft

 

Count yourself blessed. Most have one cam bolt that is froze solid. The bolts have to be cut to replace them.

 

Mine are always loose after an alignment. Get a good torque wrench and hit 100ft/lbs
