Bad spring isolators?

Ponyup1 · May 30, 2010

As many of you already know I am having a popping sound coming
from the front end of my mustang when I make a sharp turn into
my driveway.Is it possible that my spring isolators are bad?
After time do spring isolators fail on these cars?
I was talking to my friend today and he said it is possible
both my front spring isolators are bad and need replacing.
I know alot of people here run without spring isolators but,I
like a somewhat quiet front suspension.Opinions guys?

Could very well be...I had a Lancer in here a bit ago, same issue, replaced isolators...all is fine now.

Yeah it could possibly be I will find out next week.
Do spring isolators normally fail on our cars?

I wouldn't think so. Have you done suspension work recently? I am not in this forum much anymore so just asking. I would think it would be ball joint, tie rod, or other. Miles on car?

I haven't done any suspension work up front only new struts
because my old ones were worn.People and my front end guy are
telling me that it could possibly be any of these making the popping
noise in the front end ball joint,spring isolator,a-arm bushing,steering
rack bushing,and possibly a tie rod.There is only 70K miles on my 96.
My front end guy seriously thinks that it could be my ball joints.
Still trying to figure out what it is?

When did you do the struts? Last couple of weeks?
Take the tire off and check the two bolts that hold the strut to the spindle. See if one is loose. I have seen that happen. Re-check the upper strut nut.

I had a 2000GT. When the miles and age get up there, ball joints and tie rods wear out. Best thing I ever did was change the ball joints out for 2003/04 Cobra a arms (new bushings and better ball joints), new outer tie rods and a rebuilt steering rack (new inner rods and bushings). I did the A arms first at about 70K. Steering rack and outer rods at 115K. Should have done them WAY sooner. You don't notice the car losing its tightness because you drive it everyday (atleast I did).

Car drove like a new car. Even the new owner 2 years later still states the same.

I do not think it is the isolators.

I replaced my struts and shocks a year and a half ago.
Thanks I will check that tomarrow.

Thanks for your insight.
I will inspect all that.

Well, since the struts were replaced that long ago, I don't think that will be it. Doesn't hurt to look.

I would think ball joint. Easier to replace the entire arm. Also, the outer rods are too easy and cheap not to replace while your in there. 2003/04 a arms are great if you can still get them at a good price.

Yeah I heard about people doing the 03/04 Cobra a arms.
It improves the turning radius by 10%.
