Lubricating Control Arm Bushings
 

My suspension has become pretty squeaky since having my lift installed. I've tracked down the squeaking in my suspension to a few different locations. One is the front-driver lower shock mount, one is the frame side bushing on the front-passenger LCA, and the other seems to be coming from the front drive-shaft slip joint (stock drive-shafts).

On the LCA, there's actually a zerk fitting to grease bushing, but its in a stupid location. No way to reach it without dropping one end of the control arm. So my question is, are there any issues with dropping one end of the LCA? Do I need to do anything to keep the axle from rotating, or the front spring from unseating? On the lower shock mount I'm thinking that i need to grease the shock bolt/pin with some synthetic or lithium grease. Still looking at the drive shaft for boot failure and such. Have about 7k miles on the jeep since the lift.

As long as you are torqued to spec on those bolts, I would first hit them with silicone lube, let it penetrate overnight. Next, you can safely drop an lca. I would support the vehicle and get the weight off the axle.

Just drop one arm at a time. The hole might misalign a little. Have a helper push from the front of the tire.
White lithium spray works great I her. Fluid film is another great product for rust prevention and lubrication.

Funny how many times lift installers torque control arms while on the rack. I guess it's easier to access them in the air instead of sliding under after the Jeep is sitting on all 4s. :what?:

yes...hence, premature failure!

a regular ratchet strap
 

will pull It back into place to get the bolt back in hook it on anywhere frame and axle

Don't torque the bolts until the vehicle is weighted in the axles. Very common mistake.

Thanks folks. Loosened and re-torqued the bolts. Not even sure the shop used a torque wrench. Some were stupid tight. Did make a difference, but will probably have to lightly grease everything anyway.

Checked the slip joint cover on the stock front driveshaft. No tears or signs of rubbing but the slip joint creaks. Any suggestions for that?

now, index their placement with a paint pen. Makes for easy inspection (visually) to see if the bolts have loosened. Saves you from putting a wrench to it unnecessarily.
