Lubracating polyplus bushings

[forestb]

What kind of grease should I use to lubracate polyplus bushings for my trailing arms.

Since it's a poly bushing, you're going to have to grease it. It won't twist like the original rubber bushings do. It's really better to use rubber bushings. I personally would not use poly bushings.*
But, since you have those, if they didn't include poly bushing grease, you'll need to get some of the special grease to use with those bushings. If you don't, they will squeak. Not just any grease will do. You need poly bushing grease like this:*

Also you'll have to tighten them securely once the car is back on the ground with the weight on the suspension. Those bushings will tend to loosen up, so you will have to check them from time to time for tightness.*
