Creaking rear suspension
 

I've got a 2001 4.4i Sport with 73k miles.

I've noticed the rear suspension creaks a lot and wondered what it might be?

Suggestions so far include:

1) Subframe bushes.

2) Upper ball joints.

3) Lower ball joints.

Any thoughts?

Thank you.

I did all the the things you mentioned except the subframe bushes. It just started creaking again. Its most likely the bushes. I did it myself in the driveway. It was a lot of work. Would take it to a frame shop next time.

The problem l'm having is identifying exactly what it might be.

Is there a way to 'test' if it is the subframe bushes or won't l know until they're actually replaced?

These have been recommended:

I had the same creak. Changed the bushing, and the creak went away for a short period of time then it came back. Said to myself why after I changed the bushings. So I found out it was both the bushings and ball joints. So considering I had to buy the ball joints I bought the complete kit. Upper and lower arm, ball joints and a few other pieces. The rear end on my x is so stiff now. Exactly how I like it.

its the inverted balljoints in the rear knuckle. thats the creaking sound

Creaking sound
 

My mechanic says it is coming from my upper rear control arms. The ball joint in them to be exact. He's suggesting I replace the control arms ($60 each w balljoint) sway bar links (one is broken) and guide rod (I think that is the same as the traiing arm or integral link at $50 each)

Labor will be $250.

Thoughts?

this is when you have to decide which parts you want oem or aftermarket. choose wisely, check out ecstuning.com and get the parts first, then bring them to the mechanic

Sounds like a good deal. Compare fees to stealer....

Job Well Done
 

The job was done, and now my X5 is onto new problems....lol
