Disintegrated Strut Bushings

[charlescfp]

Happy 4th...

Was searching for info about strut rod bushings failing and ran across this thread.

I am finishing up a 61 Futura with a V8 conversion and having trouble with premature failure of the strut rod bushings. The entire front suspension has been updated with the V8 Falcon parts... including the Strut Rods & Bushings.
I have had 2 sets of bushings fail in about 2000 miles, Both sets were from Falcon Parts (1962-1963 STRUT ROD BUSHINGS, C2DZ-3A187-A). Both sets were installed properly and checked by a reputable alignment shop that is very familiar with our older cars. And I've replaced the bushings from other manufacturers on other older Fords and they have lasted for years.

I have had good luck with stuff from Falcon Parts but I noticed in this thread that others have apparently had similar problems with these specific bushings from them... so I am now assuming the problem I'm having is associated with the sub quality parts. As a side note, I did contact them and they stood behind there bushings... it was apparently "my fault" for improper installation.

So, I would much appreciate some feedback on some questions...

1. Is it likely my assumptions are correct about the 2 sets of bushings from Falcon Parts being poor quality?

2. Any recommendations from members that have had a more favorable experience with other "rubber" OEM or aftermarket bushings for this application?

3. Any thoughts on the Heim Joint style strut rods that eliminate the bushings? Pros & Cons? Harsher ride?

Any feedback is appreciated...

Thx - Fred

Fred,

Tough one. Rubber does fail, and these parts do see a lot of force. I have a hard time with FP taking a hard stand on quality. There is not a lot of wrong you can do installing these, though it's not impossible either. That said, the mix-match of parts you get for strut rods bushing is all over the place. I did them on Don's car (the 61 "Grandad's car) and had to machine the bushings to make them work. The fact they machined at all gave me reason to pause and wonder.... "how long will these last?"

The purpose of the strut is to hold the lower control arm in place as it moves up and down with the rest of the front end. These stresses are significant. I've seen these mechanical pivot-style struts and I can't see how they would make the ride more or less harsh. The factory used rubber because it was cheap, but I see this similarly to the spring perches that are now made to pivot on bearings instead of rubber. The ride is much improved in my opinion. Granted, when rubber fails you may still have cushion you will lack when you have hard surfaces and things fail, but that's just an indication that it is time to change the part rather than living with it a while longer because the failure was "quieter."

I know a member, Jay, who's had a set of these mechanical struts for a while he's been wanting to sell. I had them for a while (post swap meet haul for club), but I think he still has a set. They were not cheap items new and I don't know what he wants for them, but would be happy to contact him for you. He's not active on this site and lives up the other side of Burlington as I recall. If interested, let me know and I can get you in-touch with him.

Thx... In hindsight I could have been less critical of Falcon Parts and more to the point. They sell the stuff, not make it... but should stand behind what they sell. I was more curious if other members had experience, bad or good, with the Strut Rod bushings they sell.

I am more interested in what other members have had success with. Any feedback including manufacturer appreciated... keeping in mind I am using '63 adjustable Strut Rods (with later 62-65 LCAs) which, as you're aware, are different than original '61. Anyone have any experience with the MOOG K8122 sold for the 64-65 Falcon?

I am considering swapping to the mechanical strut rod and actually have a set that I bought some time ago from PTP Engineering. I bought the DIY Kit instead of the complete strut rod. It requires cutting the LCA end off the stock strut rod and having it machined & treaded to use the Kit... my thought was to save some money. Not sure it does in the end. Nice stuff but wanted to be sure that was what I wanted to do before proceeding.

Do you know if Jay actually used/tried the ones he was selling? May not be a bad idea to put me in touch with him in either case.

Hello, Fred.

I bought two sets of strut rod bushings from Falcon Parts & they both failed at about 1500 miles.
A set of "Made in Argentina" bushings failed at about 550 miles.
Then I bought a fourth set of bushings that Falcon Parts said had come from a new supplier. Those bushings have held up for over 5000 miles and still look good (knock on wood).

Thanks, Dennis.

First set:
From Falcon Parts.com: “SKU: C2DZ-3A187-A,1962-1963 Strut Rod Bushings. This part is the Strut Rod Bushing Set designed to fit all models of the 1962-1963 Ford Falcon & Mercury Comet. This set includes 4 rubber bushings, 4 steel washers, 2 steel sleeves and the 4 nuts.” The price was $32.95. They were installed on 8/30/14 at odometer = 23791.
The bushings disintegrated and were replaced on 12/18/14 at odometer = 25166 (1375 miles). Note: After the first set of bushings failed, I changed the position of the top and bottom washers to this postion: ) ( where both concave surfaces face away from the bushings.

Second set:
I ordered another rubber strut rod bushing kit from FalconParts.com and installed them on 12/18/14 at odometer = 25166.
The bushings disintegrated and were replaced on 4/23/15, odometer = 26705 (1539 miles).

Third set:
I bought a set of rubber strut rod bushing set from Performance Suspension Technologies (PST) that were marked “Product of Argentina”.
The Argentinian bushings were installed 4/23/15 at odometer = 26705 and had disintegrated by 6/04/15 at odometer = 27272 (567 miles).

Fourth set:
I ordered a set of four bushings C2DZ-3A187-A from Falcon Parts. The description said: “We are using a different supplier then our normal so the bushings we have right now DO NOT have the washers or nuts. We do hope to get our normal stock back.” The price was $32.95. These were installed on 6/13/15 at odometer = 27272.
Current odometer = 32553 (5281 miles) and the bushings still look good!!!

If the present bushings fail, I may replace them with these:
High performance strut rod bushings: http://www.jegs.com/i/Global-West/45...oductId=760572
Fits 1962 – 1965 Ford Falcon. “If adjustable strut rods are not in your budget, high-density rubber strut rod bushings would be your best alternative. The rubber bushings are stiffer than the factory type and have just enough forgiveness to allow the suspension to move without overstressing the strut rod. These bushings are recommended if the car is used as a daily driver and is not raced.” “High durometer bushings will control lower control arm location with limited deflection and still allow pivot over standard factory durometer. Provides better alignment, cornering, and braking control. Easy installation. No modifications needed. Too high of a durometer bushing in this location can cause strut rod failure due to too much resistance in the direction of pivot. That is why there is rubber in this location over other high density plastics.”

Thx for the quick, informative and helpful response.

You must have gotten lucky with the "different supplier" from Falcon Parts, as I bought my second set after that and they were the same as the first.

If I don't install the Mechanical Strut Rods that eliminate the bushing I will probably consider the bushings from Global West that you referred to. I looked at the link... they look good and seem to be made more like some of the MOOG bushings that I have seen with a built in shoulder/spacer.

Thx again... you saved me from buying the bushings form PST.

Hello, Fred.

Here is a video of the SRB-5 bushings. They say these are for racing and the SRB-4 is for street cars. I think that the SRB-4 bushings are made with softer rubber.

See: https://www.youtube.com/watch?v=cShlNItp5Qc

The dimensions of these are different (longer) than stock and you may have to re-adjust your alignment after you replace the stock bushings with the SRB-4 bushings.

Hey all. Good info. I only know that I had a set of MOOG bushing from a pile of parts I bought off of a local guy who was selling off a bunch of 65 wagon parts on Craigslist. I bought it all. They, I hope, are still intact, but now you got me wondering. I guess I will be sticking my head under there this Friday to see if they are still there.

I have already replaced the upper and lower control arms from that same batch of parts. For what ever reason, the rubber in those disintegrated. I suspected from dry-rot, but I could make not heads or tails of why they'd have failed any faster uninstalled than they would have installed.

Hi all -

Thought it was worth sharing that I again replaced my strut rod bushing on my 61 Futura last July. This time with ACP P/N FC-ES017 (note... I am running later V8 steering/suspension) and after a year and about 3500 miles they still look good. No obvious slitting or cracking as I quickly previously experienced with another brand.

My experience with ACP has been limited to upgrading the suspension & steering of my 61 Futura, but been very satisfied.

I used Duralast fa938 for my strut rod bushings.
It crossed over from moog k8122..

There was rumor these don't fit the round body falcons..
They fit my early 63 just fine..

I'll let you know how they hold up.
