Two questions regarding solid vs composite motor mounts (pre vs post '82 928s).

First: Are the pre 82 solid motor mounts as prone to failure as, apparently, based on the reading I've done, the later versions are?

Second: If they do fail, should they be replaced by the later versions (Ford substitute Anchor 2698) or should one stick with the solids?

Thanks

Andy - I haven't heard of many issues with the '82 and earlier solid mounts failing. I replaced mine last spring with the Porsche solid mount. It made a noticeable difference in reducing cabin vibrations at highway speeds. I'm assuming the mounts I removed were 20 year old 120,000 mi originals (I don't think the post '82 fluid filled ones last that long) . The engine sits noticeably higher with the new mounts. at $125 each they are more expensive than the Ford but less expensive than the fluid filled ones. I too thought about 'upgrading' to the post '82 mounts until I saw the price and read about the failures. Hope this helps.

The fact that you can get the later style mounts for 30 dollars each, and that a used late cross member is about 50, and the updated "hats" that go over the mount are about 10 bucks used, means that you can have a smoother engine for half as much as two new solid mounts, and 1/3 as much as the later style mounts. Yes, this is a difficult job. But yes, even if I was a millionaire (which I will be if I work hard enough), I would still feel that this is just stupid to spend 225 on a latermount when you can get almost an exact duplicate for 30 dollars.

Brendan,

Where can you buy the later style mount for $30

I was able to get two new OEM 928 motor mounts for my GT on ebay for $210 delivered.

Meantime, I know of two local 928 owners who installed the Ford truck motor mounts, only to have to replace them a year later. YMMV.

Ed,
This reminds me that their was a thread discussing motormounts around a year back. Several talked of using the Ford mounts so I wonder how that has all worked out.

I'll do a archive search.

Hi Sharks:

Does anyone have experience with the $26 Jager solution?

See links:

Thanks for all the input. I think I'll stick with the solid mounts.

Hey Thom,

My mounts are completely shot on my 85', which is causing a very bad vibration. Unfortunatly I won't have the time to replace them for at least 3 months, so I decided to try the speedmount as a temp fix. I would say the mount cured about 50% of the vibration. So to me it was worth it as a temporary fix, but wouldn't recommend it as a long term replacement.

FWIW -

I replaced my MM's nearly a year and a half ago with the Anchor 2698 Mounts - now problems to date with ~10K miles on them.

Earl - I found a distributor for the Corteco mounts that can be had in the 2698 (Ford mounts) in solid or hydrolic flavors. They distribute world wide.

I hope that helps Earl.

Generally speaking:
Porsche did not make the original mounts. They are not special. They are rubber, metal, and a bit of fluid. This is not rocket science.

Anyone who chooses to purchase a mount for 175 on sale, or 225 full price is very welcoem to do that. But when you can get a close replica for 30 freeking dollars, and it will last the SAME time, and fail in the SAME fashion - why spend that money there?

Ed - I know that you know some people who had the ford mounts fail. I know some people that had the Porsche mounts fail. You have every right to go and spend your extra 300 dollars on some Porsche-boxed rubber. The rest of us will work hard to find reasonable solutions to Porsche's insane parts situation.

Interesting they have a line for 993, 986 and 951, wonder what it would take for them to add 928 ....

One of my past histories is with usenet support of Ford Explorer owners. Early Explorers suffer froma a problem known as "aftershake", where the rear of the car suffers a lateral movement/vibration following front-suspension impacts with things like potholes, street raingutters, beer cans, etc. The cars seem to develop the problems after 25k or so. Lots of cures suggested by the aftermarket 'experts', including revalved shocks, etc. Ford suffered from a lot of warranty complaints from owners, and fianlly consulted with Our Favorite Automotive Engineering Company for a cure. Porsche put together a recommended package of motor mounts and a transverse rear shock, and Ford offered the kit installed for about $1500 to out-of-warranty vehicles. From MY 1995, the Explorer had a revised front subframe along with new front suspension, and the problem was 'cured' for that and later models. The motor mounts in the package? Guess!

Since then, US aftermarket companies have started making the replacements for the US-made Explorers. They adopted the technology that Porsche had developed for the 928 (and also used on the 944...) that added damping to the mount. Ford and the aftermarket have done nothing beyond taking the recommendation from Porsche and building a lower-cost version for production here.

If it wasn't for the amount of labor involved with changing the 928 mounts, I would certainly be willing to risk using the Anchor or Ford OEM-style mounts. Because time is money and there isn't enough fun in changing 928 mounts, I didn't feel at all guilty buying real OEM 928 mounts. They are languishing on the shelf now waiting for a time that's convenient to put them in. Once the new garage is finished and I can safely put the car up on high stands here, it will get done.

Anyway, thought you might want to know some of the history!

I said, I paid $210 for both (not each) new Porsche 928 motor mounts - delivered. YMMV.

I know of at least two folks who installed those Ford mounts only to have to replace them again in about a year. I'm sure if you ask them was it worth saving $250 over original mounts, they would say NO! Especially since they wound up using OEM mounts the second time.

For some things, it's ok to use aftermarket stuff, but for a job as hard and time consuming as changing motor mounts, I think it's pennywise and pound foolish. Again, YMMV.
