Have 86 apart to replace pan gasket and oil pickup seal. On reassembly noticed one of the low mileage volvo ones isnt reusable. Bottom stud and base separated from rubber body.
Anybody have recent experience substituting the Ford Ranger ones. If so, Anchor brand? Or others? Or just back to a Volvo set?
I recall from 08 or 09 that we moved away from the Anchors due to collapse concerns. Any new alternative products out there?
I did a bit of research into motor mounts a year or two ago and my conclusion is that the Anchor failures and confusion were due to Anchor changing to producing hydraulic versions of the mounts without updating the part numbers. And some of those hydraulic mounts were failing. Since then, Anchor both updated the part numbers and resolved the issues with the hydraulic mounts. The 928 community weren't the only ones having issues with the mounts.
These are my notes from my personal parts cross reference spreadsheet (the "SR" at the end of the anchor part number denotes "Solid Rubber", no "SR" means hydraulic):
I went with the Professional Parts brand for $28.79 each from Rock Auto. FCPEuro.com sells Vaico, but they're currently back ordered. Rock Auto has the solid rubber anchor mounts for about $13 each right now, but are out of stock of the other brands. You might be able to find the mounts elsewhere by doing an internet or ebay search.
The mounts that I pulled off of my 928 were the solid rubber anchor mounts, installed by the previous shop sometime before my purchase of the car in 2009. Other than corrosion, they seemed to still be holding up ok.
I don't think this can be reiterated enough, but buying anything from the large generic parts suppliers is a big risk. We've seen counterfeit fuel pumps, spark plugs, fuel injectors and even random sensors from such suppliers. I don't think it's a stretch to suggest that counterfeit motor mounts are in the supply chain too.
Where you buy is just as important as what you are buying these days.

FCP Euro and Pelican hardly count as "large generic parts suppliers". Rock Auto...maybe? But, I've bought tens of thousands of dollars in parts through them without a single issue with any part. Ever.
There's also a product from Jager Engineering called a Speedmount that will help support the motor and prolong the life of your motor mounts. It's essentially a high-density cushion that supports the front of the motor on the cross-member. It's not a substitute for a damaged mount, but once you replace yours, may make the replacements last longer. I just installed one in my 84 and have another to put into the 79. Engine is very smooth.

I don't recall specifically naming any one or more supplier, did I? I choose not to so we could avoid responses like "But I've bought from X with no problem" - guess that didn't work.
It's just an FYI to be cautious.
"I've never had a problem" doesn't really mean anything though. It's not a problem until it is, then it can be a real problem. Most folks roll the dice based on cost and ease of replacing said item. Motor mounts are kind of a PIA to do, not worth the risk to save a few dollars that amounts to less than a case or two of good beer.

Stop making vague implications and state something concrete. Which suppliers have you purchased products from that turned out to be counterfeits?
Thank you all for these replies.
That's great data organization.
Good current reminder, too, about parts supply substitution uncertainty.
Will roll the dice and get something on order today, want to finish this brown 86 week.
I actually have two other 928s in driveway into which I put Anchor (presumed to be solid versions).
84 was installed by me in fall 2007.
86 install I did in May 2008.
Wonder what they look like.
There was talk / research / speculation shortly afterward about why some seemed to be collapsing.
Never was clear to me if voids in solids or faulty hydraulic ones... or both.
Soon after, Roger suggested and economically supplied the ones for Volvo application.
Here's one, probably a generic vollvo, that suffered the misfortune of separating from the rubber:

Are they stick on, what keeps them from moving?
Like the idea.

The instructions say to grease them prior to installation to make removal easier. You use a jack to lift the front of the motor a bit to slide them in. The tapered edges contour to the cross-member. Once the jack is removed it seems to be a fairly tight fit and I don't think it's going anywhere. Acts as a high density support and vibration dampening pad. I've only just installed mine so don't know if it will move around at all, but doesn't seem like it will.
There were some discussions about the speedmounts back in the 2007 era. Concerns included extra force on the oil pan gasket, oil sump not designed for prolonged engine support, reducing desired engine movement, moving balance/force points from engineered locations. In general, supporting the motor in ways and places that it wasn't designed to might potentially cause leaks, cracks or other unspecified (unpredictable?) issues.
It will be interesting to hear how they affect things on your car in the long term. To my knowledge there weren't any long term reports from the speedmounts being left in and driven with for long periods of time. Personally, I wouldn't put them on my car, but I also put other things on my car that other people wouldn't, so I'm not judging.
