Your photos are terrible, but I gather from your words that your strut rod separated from the control arm? My friend REGIS had the same problem, and he had to replace his control arm. You might be able to bolt the strut rod to the control arm utilizing #8 hardness bolts and nuts. The original setup has the strut rod riveted to the control arm

Is it the photo or did your strut rod bushing disintegrate?, I can't see it,

Not sure what your question is, but your strut rod is shot where it connects to the frame, you need a new control arm, check scrap yards. You will need a new strut rod bushing also...

When my friend Regis needed one, my local scrap yard sent one up to him in upstate New York. $70 is a good price, but you will pay shipping, look to your local scrap yards, I believe that your control arm will look like this, here is mine cleaned up with a new ball joint and the blue poly strut rod bushings, good luck

Here it is installed, with a new ball joint and a poly strut rod bushing on my Deville

Your local parts stores should have replacement bushings and ball joints, you will need to drill out the old ball joint rivets, if you decide to replace the ball joint. Its not a bad job, when you get the part, come back here in THIS thread and Ill post the torque specs for you, its not bad, you will need to break the ball joint loose with a fork but be careful not to damage the ball joint seal, mine was a replaceable seal the OEM ball joint seals are integral if I recall..

You don't need much, you will need a large socket for the front nut, a torque wrench and a ball joint separator fork.

An important tip, DO NOT torque the control arm while it is HANGING, the vehicle MUST be at ride height before the control arm bolt(s) are torqued or you will pre-tension the bushing and damage it.

Don't try to replace the main bushing to the frame, it requires special equipment. If it looks good go with it. Or you can find a machine shop that can do the job but be careful, it requires special equipment and not all shops have it, front end shops might be helpful also, but if its ok leave it.

Ill post a procedure later along with the torque specs, its pretty straight forward,

Chock the wheels, put car in park, with emergency brake on

Raise car and support the frame letting the wheel assembly hang, use safety stands with sufficient capacity to safely support vehicle I use 5 ton truck stands,

Don't support the vehicle with a jack

Disconnect the level sensor rod at control arm it pops off GENTLY pry it

Remove the cotter pin from the ball joint stud

Remove the ball joint nut, its tricky, break it loose with a box wrench, remove it with an open end

Use a fork to break the joint

Loosen the arm to frame bolt/nut, use two wrenches to hold

Loosen the big nut on the strut bar

Use a center punch to push the arm to frame bolt out, can be tough

Remove arm

To replace the ball joint, read directions that came with joint

Put in vice

Use centerpunch and centerpunch the rivets

Use a sharp 7/16" bit with a strong 1/2" drill and drill straight and square through the rivets

Use a chisel to take the rivet tops off

push the rivets out, twist out the joint

Reverse to install, if directions don't give torque let us know

Reverse the control arm removal instructions, but apply a high quality silicone grease to the strut rod bushings where they will contact the frame, wirebrush the frame to get rid of loose rust and check the new control arm to make sure the strut rod is not worn down like your old one, that is a problem, when strut rod bushings go bad the rod bangs on the frame, yours looks particularly bad.

Torque Specs:

Strut rod nut 58 ft lbs

arm to frame bolt/nut 91 ft lbs (at ride height)

ball joint nut tighten to 88 INCH pounds, then continue tightening nut rotating it another 120 degrees so that minimum torque is 37 ft lbs must be obtained (don't ask)

Don't forget to snap the level sensor back in.

This procedure came out of my head, but the torque specs came from the book

Usually no alignment is necessary. It is good to get an alignment when you install new tires however, that is my practice.

Glad to help, let us know how it goes.

That strut rod bushing kind of keeps the control arm in place, you didnt have any bushing, how does the other bushing look on the other side?

Its possible that your ball joint was worn or this new one is worn, its hard to know...

You can get an alignment, it will help, but look for any other worn parts before you do that.

Now that you are an expert, you can do the other side no problem. did you grease the ball joint?, did it have a grease fitting?

How did the job go?

Loosen the nut and bolt that connects the arm to the frame first then while the car is at ride height torque to spec. Putting the car on a ramp helps this... doing it on the ground makes it impossible

hey mike ,,im still geting a bad squeaking and load noise from the side i just fixed ,,,it sounds pretty bad,,,im lost on what to do

Is it a rotating noise that happens when you move, is it related to when you turn the steering wheel or when the car hits a bump and bounces?
