I got my kit and plan on doing this soon, seems super easy. My questions are
What and where do i need to lube on the bushings and which kind of lube to use, upon installing the new bushings back. The few videos i watched talk about lubing some parts.
Also, i was wondering if i can take care of that clicking noise we all know of while i do this job at the same time.

Do this it works.

so according to most people here, the thick goes on the bottom. However this gentleman points out that the thick has to go on top to not have any vibrations or noise. Can we confirm the best way?
Here are my follow-up results of the two WL bushing configurations on a 2009 G37 Sport Coupe 6MT:
Thin top/thick bottom bushing w/ metal top hat washer b/t chassis and thin top bushing: very minor acceleration rumble. The rumble is not loud or intrusive but it is there.
Thick top/thin bottom bushing: No acceleration rumble...noise level most similar to OEM bushing. I'm sticking with this!
Addition of the metal top hat washer (upper stopper) to the thin top/thick bottom bushing config. reduced some of the acceleration rumble but not all of it.
All bolts were torqued to OEM specs (74 ft.lbs). The rubber washer (lower stopper) was omitted in both configs. This is my personal vehicle and is in stock form (tires and suspension). It has had a relatively dull life compared to you guys and has never been tracked, abused or in a collision. Hope this info helps folks.

When you compare spacing of the OEM bushing to the body it would appear that the thicker one is supposed to be between the diff and the body with the thinner one toward the ground. That is how I am installing mine
Side question, what are the torque specs for the diff cover bolts and the fill/drain plugs?

Anybody experiencing loud squeeking and groaning noises with these bushings? Mine were installed over two months ago. During that time I've been hearing this annoying noise more and more, to the point now where I want to do something about it. Is it these bushings? IDK, but it's a reasonable explanation. It manifests when the car is moving around at low speeds, like a parking lot, my driveway, or just coming to a stop.
I think I'm going to spray them with penetrating oil, and see if it affects the problem. Noises like this can be any number of things, I know that, but the timeline is suspicious.

I would try WD-40 before p-oil. Oil is damaging to rubber/ plastics. WD-40 being silicone based, won't damage the bushings and should lubricate at least enough for you to hear if that is the source of the noise.

The other thing I'm waiting on the ramps for is to drain & replace the diff gear oil. So... a couple of related things here that I want to address.

you may want to try re greasing them....the energy suspension grease and or the Hotchkis swaybar bushing grease (which I understand for other people's posts is Super Lube at Harbor Freight), should quiet them down...they should have come with a tiny packet of grease, but considering all the stuff you had done at once and the fact that it was a multi-day job I wouldn't be surprised if your mechanic forgot about it and put them in dry (the oem bushings are dry)
I have to say that I didn't experience any such noises but it could just be my interpretation of your description/I didn't notice

And thanks for the feedback and ideas, guys. I appreciate it.
