I'm currently restoring the rear suspension on my 75 1.8l and wanted to get other's suggestions regarding rear bushings.

My shafts are fine and I'm planning on re-using them.

I already have a set of bushings.

Mine are the "Daystar" polygraphite set that you can get from multiple vendors.

These are in AutoAtlanta packaging.

These puppies fit stupid loose in the arms...

I worry about squeaking...

I don't like straight poly bushings for the most part.

Would you use them?

What grease would you use on them?
Normal silicon grease for urethane bushings?

914Rubber has a rubber set that are reasonable. $ 44

PMB and Elephant racing have rubber sets that are far more costly. $92, $240

This car will be a mildly upgraded streetcar for enjoyment not competition.

I'm leaning toward the 914Rubber set...

What says the hive mind?

Everything is apart and has been bead-blasted and painted.

My shafts are FLAWLESS compared to yours.

I commonly use "Energy Suspensions" silicon grease IF I'm installing urethane bushings.

A bunch of it and I will usually install grease zerks/drilled bushings to allow the addition of more silicon grease down the road because every single urethane bushing will need re-greasing far more often than you might think.

They still squeak like hell...

I don't prefer them.

I ended up winning an E-bay auction that had these Daystars in with a bunch of other stuff. I'm planning on selling them or throwing them away...

Installation of a rubber bushing requires soap or more commonly diesel fuel as an installation aid which should dry up and lock the bushing to both the shaft and the trailing arm housing.

If using rubber bushings, it's critical to have the suspension fully loaded before you lock the mounting hardware.

If you tighten with the suspension in full droop the new bushings will have a much shorter lifespan.

Thanks for the responses guys!
