My guess is you have poly bushings. As said above; make sure they are torqued properly and they are greased. Keep in mind the colder weather has an affect and may not go away with more grease in this instance. But it is worth a shot.

I just installed UMI's LCA's the day after Christmas. You gotta make sure to use the lube around the bushings where they slide into the bracket (spare no grease) and then drop the car so the full weight is resting on both front and rear axles...then torque them up. After that, use the grease gun 1.5 pumps of NON-lithium grease into the fittings. Mine don't squeak at all...just like stock.

The inner sleeve of the poly bushing is designed to rotate on a bearing of grease between itself and the poly, there are two things to remember:
1. If the bushing isn't well greased during movement, the inner sleeve will rub against the poly bushings, which will cause squeaking noises and will prematurely wear the bushing.
2. Whilst it is necessary to properly torque the bolts to the specified settings, it's NOT necessary for poly bushings to be installed whilst the suspension is loaded.
The reason it's required for rubber is because the sleeve is moulded to the rubber in order for the rubber to work the way it's supposed to.

thanks for all the helpful feedback guys, though it is a bitch to have to take them off and re install them, could i just take em off with the suspension loaded, grease them, then place them back on without having to lift the car by the frame first unbolt, then lift by axle?
