Squeaking rear suspension?

Well you have bushings on your upper and lower control arms and they are probably what are squeaking. I don't remember if the stock control arms have grease zerk fittings or not, but most aftermarket control arms do. So check yours to see what you've got. You can buy a zerk grease gun and grease at the parts store pretty cheap and they are pretty easy to use.

Stock pieces do not have grease fittings. It sucks that because people are too lazy or dumb to grease parts, car manufacturers are putting "maintenance free" parts in cars. None of them last as long as parts with grease fittings. It's not as bad with rear end parts, but front suspension pieces seem to wear out pretty bad.

By the way, I would try some of the white lithium grease that comes in aerosol cans, should help with the squeaks. I would try the control arms the sway bars for possible areas for squeaks.
