Suspension Lubrication

In my 94 the front suspension squeeks a little bit. I greased the zurk fittings, but wondered what I should use to sparay on the bushings, if anything. I don’t want to just shoot wd-40 without asking if there is a better way.
thx.

Rubber bushings aren't intended to be lubricated. If they are noisey GM super lube and Kent industies has a Teflon lube which are both good for squeaks.

So if I get this, I can use it on the factory rubber correct?

If you need to. If they are quiet, I would leave them alone

You can't effectively lubricate a rubber suspension bushing. They don't have any sliding parts that would have friction and cause squeaking. A rubber bushing is bonded to both the inner and outer metal shells, and it allow movement only by flexing the rubber in between. IOW, there is nothing there to lubricate. I can't imagine what is squeaking. The one exception to this that I can think of is the frame (or "D") bushings for the swaybars. For those, the swaybar rotates inside the inner surface. If those are squeaking, then taking them off and lubing their inside surface might help.

PS - Are you sure the suspension bushings aren't actually black poly?

Rubber bushings can rub the brackets they mount in, particularly as they distort over time.

All good places to look. Next time it’s on the lift I will see what’s going on... not sure if I have rubber, I haven’t had the car that long, but i’ll find out.
