Polyurethane Suspension need some help here .

Hi
I need to replace my car's control arms bushings
I'm thinking about polyurethane bushing i think it will last longer
I found a total kit at prothane suspension (14-2007) it will fit infiniti G35 1st generation (V35) and also nissan Z350
The problem here i don't know if it will fit my car or not G35 2007 2nd generation (V36)
Amazon.com says it will fit
CARID also says ot will fit
But prothane suspension says ot won't fit
I hope someone can help here about this
If anyone try this kit or at least the 1st generation bushing size is the same or not woth the 2nd generation
I'm so confused about this
Any help will be appreciated
Thank you all.

If you have a 2007 SEDAN it will NOT fit (from 03-07 G35's. If you have an '07 Coupe it WILL FIT.

I did the entire suspension with urethane bushing in my Vett, took 4 years before it stopped making terrible noise with every bump or turn! Lubing them only lasts so long then the noise is back, forget cold weather driving you'll go ! Get the point...rubber bushings!

Energy's polyurethane bushings are not squeaky. I ride around with the windows down often and it would be really loud if it was the case. Read my post above /thread.

There are only certain places that urethane bushings should be used. In the G you want them in the compression rod and in the lower control arm (both LCA positions). Both of those shouldn't make any noise, should improve the life of the bushings in those positions and improve handling all without making noise. There are other positions where Gary is right, they make a LOT of noise, but be sure to use silicone grease and you should be noise free in the fore-mentioned positions.

That's cuz you used the right grease. If you use lithium grease for instance, it's only a matter of time before clunking and squeaking and thudding comes up.

i have a worn upper control arm bushings thats why i want to change the bushings instead of a control arm and i saw this total kit and i thought why not to do all the bushings at once
Unfortunately i bought the kit before making the thread
The kit not delivered yet
And about the grease i already bought the energy suspension formula 5 grease it's useless now

No, that formula 5 grease is exactly what you want. I have the UCA bushings in mine and they can get annoyingly loud. Gotta grease them constantly, but at least I have zerk fittings on mine.

Thank you. The grease they use is some heavy duty stuff! Hard to get off the gloves I used to put in the grease .
