Default Front coil spring removal

Is it possible to remove the front coil springs from a 1996 Mustang without removing the upper A-arm?

The way the spring looks tucked up into the shock tower it looks to me like even with a spring compressor there will not be enough room to get the old spring out.

It will come out. If you had to, I would remove the spring perch before the UCA.

I can't say for a '66 (that's what I'm assuming you meant). My '68 springs came out easily using an OEM brand compressor. I bought mine but I believe AutoZone gives them out as loaners. It may look tight but the springs compress quite a bit.

You've got to take off the outer shock tower to get the spring out.

Outer shock tower out, spring gone, UCA still on.

Once you get the outer shock tower off the spring compressor will fit inside fine and you can get the spring out safely with a spring compressor, just DON'T use a cheap compressor. If you can't buy one go and rent or barrow one from a garage or Auto Zone. I borrowed one from a a local store for $5 and I will barrow it again when I put them back in.

Everything out.

You've still got to take the spring out before you take out the spring perch as the spring sits on the perch.

I can easily remove the perch while spring is still in, if compressed (can't think of a reason why I would have to though) and I have never had to remove the outer shock tower to remove the spring.

It is a lot easier if you do remove the outer tower though.

I didn't have to remove the outer tower, nor did I remove the perch. Then again, perhaps the '68 is different.

i just replaced my springs on my 65. I took the outer shock tower off and removed the spring perches by removing the bolts with a grinder to get the clearance i needed. But i have seen it done with out doing any of that, it all depends on the compressor you use. The one i had wouldn't compress the spring enough due to the stud of the compressor hitting the spring perch. I later solved this problem with making a spacer for the compressor so i can compress the spring completely.

If you use the proper, safe tools you really need to remove the upper arm. It's two bolts, might take an extra 5 minutes. Small price to pay for your safety.

By the way, if you're thinking about replacing the perches, consider getting rollers. They are pricey ($200) but the the cheap ones have a rubber sleeve and come set at the wrong angle to accept the spring. They won't budge. I tried prying them into position once installed but wound up cracking the UCA where they bolt on. It was an expensive lesson for me.

HOLY HELL! you dont need to take the outer shock tower cover off to remove the spring lynn!

i just replaced the entire front suspension on my '65 this winter and removed the coil springs with UCA & spring perch in place, fenders on and shock tower in place.

only thing i removed was the shock so i could fee the spring compressor down in the spring.

ill agree getting it back in will be easier. esecially if you have new perches as they dont come assembled in the right orientation, i ended up shoving a large pry bar between them & the UCA to rotate them on the bushing a little to make it easier to get the spring in (shock tower in place)


plus with it removed youd have a better view of the upper spring resting point.

how does that tool work?

the UCA is what keeps the spring compressed, if you remove it you have no need to compress it as things will go banging around and release all the spring force.

then how do you get it back in if you cant have that tool on with the UCA in place?

You're a lot luckier than I was. Then again, maybe my UCA wasn't in the best of shape. A pry bar caused cracks around the perch mounting holes. Maybe my stock replacements were tighter than yours.

It all depends on what kind of compressor you use. The one I used I had no choice, it was a big clamp type compressor, there is no way in hell you could have gotten the gizmo up in side without doing such.

I always take the cover off to take my coils out. Now all I have to do is jack my car up and they can fall out.

Thanks to everyone for the information. By the time, the rear leaf springs arrived I had run out of spare time - so I ended up just taking the car to a local shop to have the front and rear springs swapped for the new parts we ordered. The new springs, shocks, and swaybar make it ride like a whole new car according to my girlfriend -- yet she raced my vette during the weekend (go figure).

Now to figure out about wheels and tires. Those factory wheels are just tooo skinny. Time to start searching the forum for recommendations about what will fit without requiring any modifications to the suspension or body panels.

Rims with a backspacing of 4.5" will fit.

We also have a thread about this kind of thing.
