Boy, I'm just full of questions! So, I have put most all my new Front suspension together except the Strut rods. I have 2 questions. First, how tight or what kind of adjustment should I give these where they mount to the frame? 2nd, the old ones were mounted with the big washer cupped side towards the rear. It looked wrong for some reason. Should the cupped side face the bushings? Thanks!

The cupped side needs to go against the bushing. Unless you're good with an angle finder and ruler, you'll want to get the front end aligned by a good shop, as the strut adjusts the caster, which can greatly affect the way your car tracks down the road. I forget the proper caster angle, but you can get that from a repair manual. Good luck!

My instructions say the same thing. The old stuff came off the car that way too. Funny thing is I called Canadian Mustang and asked them about it and they said you can do it either way?? They say if you face the rear cup washer towards the bushing it will tighten the suspension and away (normal) will be just a little more soft. I'm all crossed up on this topic now..

If you install the washer with the cup towards the bushing it will compress the bushing as the suspension moves through its travel, tightening up the suspension some. When the washer is facing the control arm(correct way), the washer does not compress the bushing and allows the suspension to move freely.

Sorry 'bout that! However, I looked at an old '67 out back, my Torino, and my '68, and they all have the cup towards the bushing, so I still think they came that way from the factory. I might have to try reversing the cups on my drag car, since it might help front end rise(?)

I don't like the idea of reversed. In my opinion, don't look to front suspension for front end rise, I prefer to try to accelerate the car forward rather than up (although with enough power and traction, it is gonna come up)

Just to add a little extra meat to the topic, while I had the strud rods out, I decided to clean and prep them for paint. So, I take them out, strip the bushings and nuts off then try to get the bolts out. Well, after tapping them out with a hammer, I wondered if I shouldn't have done that. I think those bolts were meant to stay in there. They are some kind of tap in and leave in bolts? Am I ok to put these back in? Or does this make sense?

I assume you're talking about the bolts that attach the strut rod to the lower a-arm? It's probably a good idea to replace fasteners like that with new, assuming what's available as reproduction is as good as original. Now me personally, I'm cheap, so I'd clean them up good, look for signs of wear, corrosion, or stretching, and re-use them. I believe the nuts may be lock nuts, which normally should be replaced or else slightly peened before reusing. Also, I think usually the bolts are drilled for cotter pins?

One thing I'd like to ask, has anybody had any experience with urethane strut bushings? A buddy of mine works with a guy that installed them in his '69, and he experienced two strut rod failures, resulting in 1 spin-out and one meeting with a bank. What he found was the urethane was so stiff that the strut was flexing instead of the bushing!
BEWARE!

I have had urethane bushings in front of the frame mount only, not both sides, and have not had any problems (I installed them several years ago, before I heard warnings).

I think another factor could be using these urethane bushings on a car with a loose suspension. If the suspension moves up and down freely, it seems that it would stress the rod more (by moving farther and more often) than with a stiff suspension setup. I am not about to use all urethane though, and I am even considering re-installing rubber ones on the front-side.

If thats the case, I wonder how the TCP struts would handle. They have those aircraft joints that swivel instead of the rubber bushings which seems that they might cause the same problem. Anyone using these, and if so, had any problems?

The spherical rod end should be the best way to go. You have no resistance to suspension movement, and the rod is positively located so there is no bushing deflection to change caster during operation. The only drawback I could see would be increased road noise and shock thru the frame.

just to pipe in here, my strut rod bushing washers are facing the bushings in both of my '74 Mercury Comets, one, I haven't owned forever, so I can't swear its stock, the other has been in my family since it came off the lot, I'm sure on it.

The Pictures in the 68 shop manual shows the washers cupped inwards toward the bushings.

Has anyone seen this weeks episode of Dream Car Garage? They had a 70 Mach 1 that they were installing some of the trickest adjustable strut rods on I have ever seen. I did not catch the manufacturer as I only got a glance, but boy did they look sweet.

I went through this issue already. Cup OUT, I repeat, cup side OUT on BOTH bushings. I know the busings seem to be built just right for the cups to go in but that ain't the way it is supposed to go. I got this info from some of the fastest vintage class mustang racers in the business.

Cup in imparts a much higher load on a section of the chassis that is not designed for that type of load. The strut rod is supposed to located the lower control arm and thats it. It is *not* intended to provide any spring action to the suspension. If this were the case, why would people like TCP and Global West spend all that money to replace them with rod ends.

Mr. Baer, (yes the brake guy), had a strut rod fail while on the track, and almost bought the wall in the process. He was running poly busings.

As far as the poly busings go, if you have replacement rubber parts use them instead.

That makes since, cup out would be closer to the performance rods in function than cup-in would be.

I think I'm going to go with cup out. That's the way they were installed when I took them off, that's what the directions say as well. But, the cup out was only on the control arm side. Thanks for the great feedback,

Joe
