The answer depends on do you like the way the car is performing or do you want it changed?
I have daizen sway bars and bilsten HD shocks. The sway bars squeak occasionally on bumps in cold weather.
If I were to redo things, I think I would rather stick with the regular rubber bushings and just have the bilstein shocks take away the slop

I am not familiar with the Moog bushings but I presume they're OEM equivalent.

I would definitely go with polyurethane (Prothane) bushings. The car just feels tighter with them. If you do not grease them properly they will develop a squeak though. I have had to regrease the rears once.

Ok. Thanks to both of you for the feedback. I am going to order the Prothane and if they start to squeak more than I want them to I will try out the Moog. Not much risk with the $28 Prothane purchase price and pretty easy (I hope) install.

anyone here try using the Energy Suspension Bushings? they have universal applications 28.5mm Front and 14mm Rear that we could technically use.

They're basically the same as the Prothanes, although durometer may differ.

just ordered a set of the Prothanes on Amazon... cheapest i could find with shipping prices...

I was looking for any help on a squeaking clunking noise coming from the front right passenger area on my GS430 when going over speed bumps or dips/bumps, this mainly happens and is the loudest when it is cold out. I saw some people saying it was their sway bar bushings and to either grease the sway bar bushings or replace them, and make sure bolts are tight around the sway bar and its components. Since the Prothane bushings are inexpensive and can make the car feel tighter and handle a little better so I think I will end up getting some. They have some on Amazon that are pretty cheap. It is the Prothane 18-1123-BL Black 28.5 mm Front and 14mm back if I do them right?

I was just going to get the fronts since that is where the possible issue is. Is ordering the rears recommended if changing out the fronts, will the rears make much difference in feel and handling? These sound relatively easy to install but I have not dug too deep into what I have to do and gotten underneath the car yet to check it out. I have seen some recommend using thread tape to help ensure they don't squeek along with the grease.

just installed the front and rear over 2 hrs... pretty simple and straight forward... my oem ones looked fine after 11 years and almost 90k miles... i put in the upgraded ones anyway.. the hardest part of the install was to open the new bushings to get them onto the bar... these suckers are sturdy...

congrats....so whats your impression of these? no more body roll?

tbh - i can't really tell the diff aside from maybe the psychological apsect... perhaps because my OEM bushings were still good so it wasn't a dramatic improvement which i could immediately tell... i had everything apart so i figured to just do the changeover...

here's a pic of the two sets to compare...

Mine are squeaking like all hell. I need to regrease them...
I didn't get to read through the entire thread, but whats the best way to eliminate the squeak?

If I were you, and you are going through the effort to service them,

I'd get the prothane replacement bushings.
They are relatively cheap, and they are grooved so they will hold the grease. Yay for whoever decided to implement that.

I would order from

I would also order an extra 3-pack of grease, and just double up on the grease when you install. Better to have a little wasted grease then have to do it again.

I actually plan to do this myself in the near future.

Yeah, get some prothane grease. It is very sticky so it should last a long time. You can also use silicon grease, as it is rubber/PU friendly.
