This mount is very hard to gain access to and to test for function without the being up on a rack/hoist.

I'm getting a slight knock from rear of car when driving off , coming to stop: sounds like there is enough play in the links to produce this sound.

I'll be replacing the rear link bushings and wondering if there are other sources for the knock.

Also, gas tank filler neck is pretty rusted, any sources for replacement?

Thanks
My fuel filler neck rusted out in my 2001 Touring model and needed replacing, the OEM part was discontinued and the two different parts I could find did not match what was on the car. Attached is a picture comparing the original and the first of the two parts I ordered as a replacement. This is off of amazon - Spectra Premium FN663 filler neck. The second part was identical to the non-matching first part I ordered. I ended up using one pulled from a scrapyard.

I installed the complete Energy Suspension master kit with the black bushings in my car years ago. I have not ever head a squeak out of any of them.

I have installed the Energy Suspension black bushings in other vehicles with zero squeaks as well.

FWIW, I was trying to remember why you kept emphasizing black, but and then I remembered something I read years ago. They supposedly impregnated the black with graphite to reduce squeaks. They didn't put it in the red because it discolors.

1) What is the difference between the Energy Suspension ® red and black polyurethane components?

Answer: Both are our Energy's HYPER-FLEX™ performance polyurethane formulations. Energy has impregnated selected black polyurethane components with graphite–to add a lubrication property. Additionally, both Energy Suspension ® red and black polyurethane components are engineered differently than OEM rubber components–to be free a floating and non-binding design. This allows for the additional durometer (firmness) of the components, which adds to the performance improvement of the vehicle overall.
Through its 25 years of design and formulation of polyurethane, Energy's polyurethane components are the best on the market today.
That is from years ago, but it might explain your success compared to the failure of others.

that is exactly why. Also I think the red bushings look terrible on most vehicles...

During the early years of ES (Energy Suspension) bushing in the late 70's early 80" the number one complaint was noise.

Over the years ES tried several things one of which was the graphite in the black bushing. This product made the bushing a bit more costly to manufacture so it is not available on the full line of bushing and after ES own testing they determined it really made NO DIFFERENCE.

However their current lubricant is Marine grade none petroleum grease with PTFE. If applied as per the instruction or to most any polyurethane bushing the grease will prevent the typical noise often experienced using polyurethane product in the suspension. However it is still not a guarantee to stop the noise in all applications and the grease needs to be serviced occasionally to prevent noise and keep the bushings lubricated.

I bought the full RED Energy Suspension Kit off eBay about 3 years ago and had my mechanic install it. Not sure if he used any extra lube but I've never heard any squeaks from the undercarriage since they were installed. I just had a look underneath and you can hardly tell it was the bright red kit. Just a little red showing on all the bushings and pieces.

You might want to tell them to update their website then. They still claim that "select" black bushing are graphite impregnated.

Answer: Both are Energy's HYPER-FLEX™ performance polyurethane formulations. Few of our selected black polyurethane components contain graphite to add a lubrication property. It is not added to the red because black graphite discolors the red polyurethane. Graphite does not compromise our polyurethane formulas.
