The originals were not from Energy. I don't remember who they were from.


Here are some after pics of what was left of the old body mounts.
They were just chunks and dust.

Interesting how, with the exception of Willcox, all the "supporting" vendors are not to be found on this thread.

I've been contacting them with a link to this thread.
Need more participation from everyone if this will get resolved.

Can those that are having issues with the poly mounts supply us where you purchased them and part # if you have it. I purchased my set from set from Ecklers 2 years ago, I will have to find the invoice for the part #. I'm curious if all the poly mounts have a problem or if its just one maker?

I'm not defending other vendors, but most vendors do not install what they sell. Most don't have a facility where they actually install the product and see the end result. We do install what we sell in most cases(except poly suspension items), and if there is a problem with a product we will pull it.

Poly suspension bushings and other products are requested repeatedly, even after we try to educate the customer they still buy it. Like I said above, if you want something that will tighten up the car for racing then poly is your boy... aside from that I expect it to fail, squeak and cause issues.

IMHO...

JrRifleCoach

That's fine. So what can you say about the problem at hand?
Are these your bushings? If not, can you offer P/N's and prices to help these guys along?

0Willcox Corvette

I can say nothing about the problem at hand..

Why? Because I've stated over and over on this forum to stick with the stock items. (and yes they will fail too). I've educated my employee's on why I don't install poly in our shop and instructed them to highly dissuade customers from buying poly.. but that's about as hard as we can push it.

Nope... They are not my bushings..

And nope... I'm sorry, I'd not offer you poly part numbers to buy...

I'm a strong proponent of the original stock suspension not Poly and like I tell my employees.. I can only drive the bus, I can't tell you or the customers when to get off...

IMHO (again)

Willcox.. (I feel as if I'm sticking my neck out so chop easy).

now I understand why my mechanic did not allow me to install poly motor and tranny mounts. I insisted constantly and he tried to change my mind but I didn't budge at the end he installed the rubber and told me it was better PERIOD. I was still mad about it and wanted to do my suspension in red just because it looks cool and "easier" to install but im sticking to rubber thank you guys.

JrRifleCoach

That's fair.
I've purchased door panels, carpet sets and seat covers from you without a problem.
Nothing but great service for my 86 Coupe.

In this case we have poly bushings that are most likely not from the high end mfgrs.
Unfortunately this thread gives the cons a solid position on not using poly.
But that is not my objective.
I'm looking to locate the mfgr of these obviously defective parts.

So if the C3 guys here can't clarify the part numbers or business the parts were purchased from, my point is moot.

Just had the opportunity to get under the car the other day and this is what I found, all four are like this.
These bushings are less than a year old and were purchased from one of the vendors listed on the left. I now have new rubber ones on order.

Mike Ward

While you're changing the bushings, remove the shipping bands from the spring too.

JrRifleCoach

who? Your not doing us any favors by simply saying "on the left"

My defective Poly leaf spring cushions were part 38303 purchased from ECKLERS in March 2010. I noticed the defect at 400 miles but have no idea when it started. I just happened to be looking under the rear and saw them all busted up. I first they were rubber until i checked my stack of invoices. I started a seperate thread with photos but was directed to this already started thread.

My '74 frame is stripped, ready for sandblasting and then paint. I've assembled the control arms and used poly from Energy Suspension, but haven't gone any further, waiting until I'm ready to work on the frame. Has anyone had trouble with upper/lower control arm poly bushings?
Also, any video's on rear suspension bushings?

My 5 year old VanSteel poly bushings look new!! (not many miles on them but they look new!!)

I replaced all body mounts and bushings with Rubber - I don't remember from which vendor. They are ALL cracked and disintegrating even though I barely drive the car. Its not easy replacing the parts and then to have them fail within a short amount of time is just bad.
I would go back with rubber all the way around if I knew the pieces were of high quality.

SuprJames

Not to bring up an old thread, but ran into this on Google while looking for poly alternatives. My '82 had this problem first after rebuilding the entire car. Ever single piece of poly in the car had disintegrated after about 7 years. Now all the poly in my '72 is doing the same. It is no longer safe to drive.

It doesn't just gradually get hard and deformed like rubber, it simply falls apart and almost all at once. Wondering if anyone has found a cause or a better solution than poly.

I could post pics if anyone wants to see, but it basically looks like all the pictures in this thread.

This popped up in another thread and some bushing rubber or poly are crap some are good what was a kick in the head to me,
The VBP vette brake products ones on my donor chassis that was never used just built look almost as bad as the OP's in this thread, I emailed VBP but they didn't care...it's a me problem.

But they will be happy to sell me new ones.....

JrRifleCoach

Seems Willcox has the best solution really.
Stick with OEM rubber is the best bet.




FWIW My SnapOn dead blow hammer head shattered just like those bushings.
No warranty either..

The13Bats

Is it only the OEM from "Willcox" or your just like any rubber over poly,

Nothing wrong with rubber if it's good stuff but I see too much of it crack way too soon, I would love to find fuel lines that last more than 6 months to a year...
