Removing Lower Control Arm

Anyone know where I can find a write up on how to remove an LCA? I need to replace my terribly squeaky bushings

Service manuals are at my house. I can tell you in a couple weeks.

Should be something like, pop out the ball joint and remove two bolts in the lca.

Removing the lower control arm will REQUIRE an alignment. The LCA has the camber set washers in place and removing them to reinstall would leave a slight to drastic change.

Pretty easy really to remove
Up on jackstands, jack under the control arm
Remove lower ball joint
sway bar link etc
mark where the camber bolts are set at ( that way when it goes back together it'll be somewhere close)
Remove the two camber bolts and drop it down out
Are you sure its one of the bushings in the LCA? Very seldom here of that

Mine are stock with over 200,000 and no noise

Is it on both sides?
If it's on the passenger side, check your CAI heat shield if you have one installed.
Mine was rubbing on the inner fender and I thought it was the LCA. Took many days before I figured that one out.

In order to get it out of the knuckle I have to take the clevis off though right? I got that far last time and there wasn't enough room to lift the ball joint out of the knuckle because the hub was interfering.

Tom - I have no idea but I've replaced my UBJ, pulled out my tie rod and the ball joint felt fine. I've removed my sway bar entirely and it wasn't that. Like I said I popped out the LBJ and that seemed to MO e freely as well. The only thing I haven't done is remove the upper and lower control arms entirely. The creaking noise is extremely loud and it does it while turning the wheel and during any suspension articulation. It certainly isn't a heat shield, it sounds far worse. Could it be my steering rack?

Will it make the noise while stationary if you compress the suspension or do you have to be moving?

Yes, even when stationary. It even does it when I close the door too hard.

So I pulled the tierod so I can turn the hub by hand and the noise is there but very hard to tell where it is coming from. Could it be from on of the CV joints on the axle?

And my follow up to this is - does anyone have a writeup on replacing an axle? SMH...

I'm guessing that I'll also have to remove the clevis? Thanks Tom, got a new one on order

Good news! I have the new half shaft installed!

Bad news... the half shaft wasn't the issue. I believe its the lower ball joint and it doesn't look replaceable... can anyone confirm? Do I really need to buy a whole new LCA?

More good news... Lower ball joints can be replaced without replacing the LCA (unlike the UBJ & UCA). Mine have been done already. I have greasable LBJ's in there now.

Wonderful news. Now that I have it all put back together I can't wait to take it all apart again and press that rusty piece of crap out
