new shocks advice
#1
Hey folks,

I think I need new shocks, at least at the front, because these rubber things have started cracking:

I'd like to ask a few questions about replacing the shocks:

1) What's the procedure? Does the car need to be lifted or can it stay on the ground?

2) I can replace with standard shocks, but are there certain shocks that improve handling that I should be aware of?

3) Will new shocks change the stance of my car? Currently this is how it sits:

Thanks!

Vincent.

You could start with just replacing the shock tower bushings. Some of the aftermarket bushings are made with some pretty cheap material and can break down in a couple hundred miles. Replacing with poly generally takes care of that problem for a long time. https://www.summitracing.com/parts/ens-9.../overview/

Changing the shocks typically involves jacking the front up and supporting the vehicle since removing the front wheels really helps gain access to the nuts and bolts inside the coil at the bottom of the shock at the coil perch.

I'm sure others will chime in on the recommendation of what to replace original stock shocks with. Be careful with getting shocks that are too high performance since the ride can get pretty stiff and harsh. KYB and Koni make some decent replacements at reasonable cost.

I've used KYB for gears and they are great. They improve handling but don't reduce comfort.
Plus they're pretty cheap and offer great value for money.
You need to jack the car up and remove the wheels to gain access to the shocks at the bottom.
You don't need to compress the springs, it's a simple task.
DO NOT remove the band that holds the new shocks compressed too early or you'll have a hard time putting the shocks in as they'll expand.

The stance and ride height are determined by the coil springs, not by the shocks so nothing's gonna change.

Got KYB up front and Koni adjustable in the back
with new 5 leaf springs. Stiff ride and great handling.
Car has factory competition suspension package.
As Luxstang mentioned, KYB's are relatively inexpensive,
Koni's are not.

I been running KYB's on both cars for years. They been good for what they cost. The only problem is I bought the one's recommended and ended up with the shorter (when fully extended) front shock. they pull the top bushing and splits it when the car on the lift. The longer shock leaves less spring down pressure. I had cut some donut out of flat belt material and use them on top. Problem fixed

Koni front and back. Went from original tired ones to these years ago when these were not sold for gold prices.
I recall car felt totally different, much safer. Comfort is great.

For the upper bushings on front, the summit Polyurethane should be fine. I make my own from polyurethane plates for years, as its easy
and cheap , but for 4 dollars its no brainer, and much better than rubber ones.

Not really, springs will. Changed mine as well with stronger versions with original size. Car was too high on front for my taste, so cut one revolution
and got what I wanted.

73 modified Grandé 351C. Almost done. 
71 429CJ. In progress

A little refresher on why the shock upper bushings split.
Remember the special tool that you use when you lift the front of the car? Depending on the shock it can run out of travel before the control arm gets to it's lowest position. This puts all the force of the spring on the bushing and causes it to split. It also puts a shear force on the rubber bushing in the radius rods up front and can cause them to split also. Anytime a Mustang is lifted in the front you should use the special tool to stop the travel of the upper control arm. It was a standard Ford tool and lots of people make their own. You can also cut a piece of wood and put between the frame and control arm if you do not want to build steel.
Do a search for the thread on the subject. I tried to do a screen print of the tool but it went crazy when I put in post. I tried a word document this time see if it works.

Yeah I’ve seen the tool, it’s also mentioned in the book from Haynes. Maybe I can make my own from some scrap metal.

About that tool...:
One thing I always wodered is how do you intall the tool prior to lifting the car when you need to lift it before you can access the area where you put the tool?!?
I never had any bushing crack on me btw, no matter how I lifted the car. It does seem others have though....

Tried to get Koni's for my front shocks but did not sell them
in the States, only rear.
