Moog strut rod bushing failures

We're trying to figure out if this is an isolated incident or if it is more widespread
than any of us know.

If you have had a failure of Moog #K8659 strut rod bushings, please let me know.
These are the "problem solver" line of bushings.

I have had two failures so far this year and The Great Obucina just had
his fail in exactly the same fashion.

See the attached photos:
The top left is my most recent failure two weeks ago.
The top right is Joseph's failure last week.
Bottom is of bushings in new condition.

Something is not right here.

yepper, that failed bushing was close to letting my wheel go bye bye. It happened while pulling out of a parking space on wednesday night...I almost decided to go to the drag strip earlier that day:eek:

What did the parts dept where you got them say? Isn't there also a warranty, so at least you'd get free replacements?

I'd also suggest writing up a detailed report, (including those pictures), and send it off to:

World Headquarters
Federal-Mogul Corporation
26555 Northwestern Highway
Southfield, Michigan 48034
U.S.A.

Phone: 248/354-7700
Fax: 248/354-8950

They're the manufacturer, and I'm sure they'd be interested, especially if you mention the liability problems they'd have if failure of these components caused a serious accident. I'd mail copies to several departments, such as head or manager of the MOOG Division, warranty dept, legal dept, customer relations, even the president of the company, (be sure to include your contact info so they can get back to you). Sooner or later it's bound to get to the right people, and if there IS a design defect, I'm sure they'd like to know about it. If it were something non-critical, (like floormats), I'd just say blow it off, but it might be worth your while if you were instrumental in helping them determine the cause of the failure. New from the factory last like 10 years, so there's definitely a problem somewhere I'm sure they'd like to know about.

The first call was to the parts store. they will help in any way I ask. I am now talking to Moog.

Please, anyone who has these installed, check them ASAP (especially the front side).

DanU went through this several years ago. I believe he went through 3 or 4 sets of them before he went back to Ford bushings, and didn't have any problems after that.

agree with dode...DanU has been there and done this.

for some reason the MOOG strut rod bushing doesn't cut it.
Stick with the FORD part.

I guess there is a reason Rich at MN12 includes the Ford strut bushings with his poly kit

Those are the bushings that go to the frame right? How are the Moog bushings that go to the LCAs? Do those last or should I stick with Ford on those to? I was getting ready to order some front suspension stuff from Rock Auto and those bushing were on the list....anyone know the PN or price for the Ford bushings?

I believe those are the LCA ones Aaron. Rich sends the OEM LCA instead of Poly

These are the strut rod to k-frame bsuhings.

I had these for over 2 years now. They still look brand new. Did you have the nuts tight enough ? It looks like the sharp edges in the k-frame cut through them.

I rebuilt and 'rebushed' the front of this car 5 months ago. The previous set was in for 1 1/2 years.
I only changed them because everything else was new.

If this were only one car I could just attribute it to an error like a loose nut but it is more
than just one.

well, we may have a little more information.

there were bushing kits that had been shipped a few years ago that had an incorrectly sized
steel sleeve. The sleeve should be 2 3/4" in length but these kits had 3" sleeves.
It is possible that these kits are from that batch.

Now I just have to get inspired enough to take the front end apart again:mad:

Read the thread and thought I would add my .02

The Moog (blue) problem solver bushings are not polyurethane. They are Thermo Plastic.

The inner sleeves included with the K8659 are cheap. Rolled steel with a gap down the side does not allow for a very tight fit over the strut rod. I had custom DOM steel tubing cut and machined to fit over the strut rod tightly and not deflect under load. The two piece OEM Ford ferrules for the front strut rod bushings work pretty good until Ford upped the price by 300% on the front ferrule. They were a non reuseable sleeve as they compress and interlock preventing them from coming apart without destroying the front ferrel.



The design I came up with and it so far has worked well. The two polyurethane bushings with the Yellow Zinc plated sleeve.



I tested the Moog (blue) thermo plastic bushings many years ago before the polyurethane bushings you see in the FSK100. The thermo plastic would deform and crack under my tests. The rear strut rod bushings in the MN12 FSK100 kit are Ford OEM and the reason is they are not really a solid rubber bushing. OEM design is a saucer shaped steel bushing covered in a thin coating of rubber. The Moog (blue) rear strut rod bushings cracked and failed in my tests again.

MN12 Performance FSK100 install
