Just had to throw this out- if you're on the fence about installing poly bushings like Energy Suspension, DO IT! Did in my '92 and all I can say is the difference is amazing. Yes, I know, it's a '92 with 10 year old stock bushings, but trust me, it did not feel this solid in the corners when it was new.

does it squeak, also which bushing did you install? the hyper/flex master kit? Everything except for trailing arms bushings, basically?

No squeak- but that's in the prep. If the full kit doesn't come with grease (I bought my piece by piece- mistake), get some synthetic grease and lube all bushings, sleeves, etc. Big thing, like all suspension work, DO NOT fully tighten/torque mountings until the car is back on the ground- otherwise you put the parts into a bind.

Shit, that's gonna be a pain, cause I was going to go by the book, and torque everything to spec.

Well, you still do- but anytime your working on a piece of suspension with a bushing that will be under load, you MUST not fully tighten & torque the bolts until the car is sitting on it's own weight.

If your bolting the top of a shock, that's no problem. But if you're bolting up a control and you do it while it's up in the air on jack stands and the wheel is hanging, and then sit it back on the ground, the bushings will essentially be 'wound up'. Know what I mean?

What you do is mount everthing and just snug the bolts- lower the car, THEN actually torque the bolts. That way when you sit the car on it's own weight the bushing was able to rotate in it's mount freely, and now is ready to be torqued.

After I poly'd my front end I had awful squeaks cause I didnt lube em up. but since I did that I haven't heard a noise.

 

Thanks for the info on torquing them down. Hadn't considered that whole scenario, yes it makes sense.

Also, one of the installs I was reading said before you lube to make sure that the receiving surface has been cleaned...

quick, which is better for polyurethane bushings:

1. Teflon Tape (swaybar bushings)

2. Silicon Grease

3. Lithium grease

 

Definitely the silicone grease- it will hold up much better and much longer than lithium grease well. silicone grease will resist water where as litium can & will be broken down by it.

 

LX4Cyl you read my mind on your post. I heard that any petrolum base grease will eat at polyurethane bushings over time. Is this true? I need to re grease my neuspeed sway and I found some white lith but when I read the contents it had petrolum in it. I read that you can also use boat grease since they are water proof.
